Pioneer DJM-S9 Review

The first thing that struck me was how light the DJM-S9 is – it weighs like a DJ controller, mainly because the bottom is made of hard plastic instead of metal. It doesn’t feel cheap, but I would’ve wanted a more robust construction, especially since you’re bound to take this around if you’re going to be DJing with it at gigs or showcases.

It’s got two pairs of Master outputs (XLR and RCA), plus a pair of 1/4″ Booth outputs. There’s a combo XLR input for connecting a mic, an RCA Aux input, plus two pairs of phono/line jacks for hooking up your turntables and CDJs. This is a two-channel mixer only, so while you’ve got inputs for up to two turntables and two CDJs, you can only use two of them at a time.

From the get go the volume faders are nice and slick, plus the new Magvel Fader Pro crossfader also feels great – if it doesn’t, you can adjust how loose or tight it is depending on your preference. I like to have crossfaders pretty loose, they kinda remind me of the Stanton Focus Fader from the 2000s in those old scratch mixers.

My review model is the gold version, and apart from the flashy / garish appeal (depending on how you feel about bling), it’s completely identical to the standard black model.

It’s meant to work with Serato DJ (it’s got controls for Serato DJ FX, which we’ll get to later), but I found videos online of it working with Rekordbox DJ (plus mapping), and even Traktor Pro 2, but none of them work as tight or straight out the box as Serato DJ.

I hooked up a matching pair of PLX-1000s (so much gold right now), connected my speakers and laptop running Serato DJ, and was off.


One word: complex. Part of what made battle mixers of yore attractive to scratch DJs was how spartan they were: two channels and a smooth crossfader were all you really needed – some scratch mixers like the Vestax 06 didn’t even have three-band EQ and master output cueing! Of course more recent scratch models like the Rane Sixty Two have included modern features like cue points and dual USB, making for a more robust mixer, but in terms of capabilities (and layout crampedness, in my opinion), this takes the lead.

It’s a complicated-looking mixer, but let’s take it apart section by section. There are three parts to the DJM-S9: The top portion includes the EQ, output and browse knobs, loop buttons, and switching matrix. The middle contains the FX selectors, paddle switches, and performance pads, and the bottom contains the volume and Magvel Fader Pro crossfader, as well as the customisation controls for these faders.

The DJM-S9 features EQ knobs for the highs, mids, and lows, as well as trim pots. These all have a nice, quality rubber knob cap that feels great. There are also filters for both channels, but the cap here is made of a hard plastic. I’d have preferred this to be the same rubber material as well, but I guess Pioneer couldn’t find any gold rubber caps here.

The Master and Booth output knobs are also located here in the EQ section of the mixer.

Near the top of the unit is the knob for switching among the input sources for both channels. The DJM-S9 comes with two USB sockets for plugging in two laptops, and you can select whether you’d want a channel to control either laptop through the switching matrix. You can also choose whether you’d want to run a line or phono input through the channels, so if you want to play from CDJs or spin actual vinyl during your DJ set, you can do it here.

There’s a browse knob per channel on the DJM-S9, as well as load and navigation buttons for your library. There’s a “4 Beat Loop” button, that automatically sets a one bar loop (one bar = four beats) in Serato DJ, and there are buttons for halving or doubling this loop. You can also set manual loop in and loop out points by pressing the Shift button, which is found tucked away beneath the Booth output knob and surrounded by the other EQ controls. Not an ideal position, but it works.

The FX section on the DJM-S9 is among the most complex I’ve seen. There are two banks of switches: on the left you’ve got Beat FX Select, which lets you choose from among six of Pioneer DJ’s onboard effects (echo, backspin, flanger, reverb, vinyl brake, phaser), and on the right you’ve got Serato DJ FX Select, which lets you choose from among the six Serato DJ effects slots.

Clicking the FX button of your choice brings up the effect on the DJM-S9’s centre display, which has two parameter buttons that let you modify a setting of a particular effect (delay time, in the case of the delay effect, for instance), and there’s a level/depth knob for controlling how much of the effected audio is sent to your Master output.

ips and tricks for Google's Daydream View

Forget Google Cardboard, Google's first VR headset is available and it's pretty darn good. Before you dive deep into a virtual ocean, or find yourself trying to diffuse a bomb with the help of teammates, there are a few things you need to know.
First, download the app

As you wait for your Daydream View ($77.46 at Amazon.com) headset to arrive, or while charging up the remote for the first time, take a second to install the Daydream app on your phone. Without this app, the headset is just a fancy looking pair of glasses.

When you place your phone in a Daydream headset, it's this app that runs the entire experience. The Daydream app is also where you can find Daydream apps, and adjust settings.
Give the controller a solid charge.

It will be hard to resist the urge of putting Daydream View on and playing right away, but if you start playing without a fully charged controller you will run into connectivity issues. Google suggests charging the controller for 2 hours before you use it for the first time. Doing so will give it enough juice to power through 12 hours of use or an entire day on standby.
Install new apps on your phone, not in VR.

You can browse Daydream apps while you have the headset on, but the process is so much faster if you open the Daydream app on your phone and go through the apps there. Plus, if you have to enter your password before every app download, you're not going to enjoy pecking away with the controller on a virtual keyboard.
Are you a lefty?

Surprisingly, during the setup process you aren't asked which hand you hold the controller with. (As someone with two left-handed kids, this is a big oversight.)

You can set your preferred hand, however, in the Daydream app's Settings under Controller or from the Settings icon on the homescreen when actively using Daydran


Depending on how often you wear Daydream View, you may need to wash the face pad to keep it from getting smelly. Gently pull it out, and hand wash it with a bit of warm water and soap.

After it's all clean and dry, place it back in the headset. There are some patches of velcro that you need to line up, but outside of that it's a breeze.
Speaking of velcro...

Don't place Daydream View in a bag or backpack where you have velcro fasteners. It turns out, the fabric Google used for Daydream View is susceptible to getting caught on the velcro, and it could damage the fabric. Nobody wants a headset with strings hanging out of it.

How many times can a 50000 mAh power bank charge your device?

What is a 50000 mAh power bank?

Most power banks hold between 2,000 and 20,000 milliamp-hours (mAh) of charge – the higher the capacity, the larger the physical size of the accessory. The largest EasyAcc models on the market do reach capacity of 26,000mAh, but it’s a rare sight among average consumers due to the size, weight, and price.

Go to eBay and Amazon you may find power banks that are claimed to be 50000 mAh of charge or even an astonishingly larger amount. Some of them are solar enabled power banks, some are traditional Lithium battery enabled power banks. A large number of customers doubt if 50000 mAh really exist, what they are suspicious of is whether the capacity does reach 50000 mAh. However, with the development of technology 50000 mAh power bank will be smaller, lighter and more user-friendly, people who do heavy gaming and video watching will benefit a lot from it.

ow many times can a 50000 mAh power bank (like GOAL ZERO YETI 1250 )charge your device?

It’s quite simple according to the basic rules: divide 50000mAh by the battery capacity of your device. By checking the mAh number of your device capacity you can get the result without a hitch, wait for a second, is it already done? Not yet. Consider this, when power is transferred from a power bank , there is always loss due to resistance. None of the latest Power Banks is able to transfer 100% of their actual capacity to a device, so the basic calculation rule can be only applied in the best case scenario. How many times can a 50000 mAh power bank charge your device indeed?

Let’s add the conversion rate into the calculation first, rating between 80% and 90% are the current industry standard. Be aware of that high quality power bank obtains higher efficiency rating for sure. Hence, the approach of calculation becomes:

Power Bank Capacity Rating (mAh) × Efficiency Rating (80% to 90%) ÷ Device Battery Capacity (mAh)

For instance, assume your device is an iphone 6 and the efficiency rating is 85%, you can charge your device roughly 23.48 times. The battery capacity of iphone 6 is 1810 mAh and 85% efficiency rating is on an average level.

1. Are you using your device while charging?

2. Are you charging from flat battery to full?

3. Does your power bank discharge when it is not in use?

4. Temperature during charging affects the result.

5. If your power bank is a solar one, the calculation will be more complex.

These factors more or less will affect the final result, in order to get a better result I strongly recommend to use a qualified power bank, not only for better utilization, but also for safety concern.

WATCH: What Happened to Solar Power in the US During the Eclipse


On August 21, solar power facilities across the US faced a big test when the sun was eclipsed by the moon for several hours between Oregon and South Carolina. Despite the unavoidable disruption, it seems that current infrastructure was well equipped to handle the situation.

Solar Edge tracked solar energy generation from over 300,000 systems to produce the video below. It demonstrates that while the eclipse did cause interruptions, panels were able to resume harvesting energy not long after the event, with systems as far east as Idaho and Utah reporting high levels of production by the time the totality was over South Carolina.

The day of the eclipse was also a great success for the California Independent System Operator, which operates the state’s bulk electric power system. California has more solar energy capacity than all other states put together, but the heavens aligned without major issues. Mild weather that negated widespread need for air conditioning, and plenty of water in the reservoirs used for hydroelectric pumps, helped engineers maintain power supply with any major outages.

Over on the east coast, in North Carolina, the story was largely the same. Even when the eclipse was at its most dramatic, and 1,700 of the 2,500 megawatts available in peak conditions were blacked out, Duke Energy was still able to service its customers.


Solar energy is getting more and more popular around the world, but adoption rates in the US are expected to see a sharp uptick when Tesla’s cheap, convenient roof panels become available to homeowners. If this comes to pass, it might spur some extra considerations for the eclipse in 2024.

This time, the states that rely most on solar energy managed to avoid any hiccups, thanks in no small part to the skilled engineers responsible for operating the system. It’s worth noting that Duke Energy had natural gas generators ready and waiting in case it couldn’t meet demand in North Carolina.

Keeping an alternative source of energy in reserve is essential for this kind of scenario — but natural gas generators might not be so palatable if the country has shifted even further toward solar energy in seven years’ time. Instead, Duke is researching large-scale battery technology that could store energy while the sun is being obstructed.

“Solar energy, by definition, is an intermittent form,” says Lio Handelsman, the vice president of marketing and product strategy and co-fonder of Solar Edge, to Futurism. “Think of our water. Imagine a situation where the water company has to pump from the ground exactly the amount of water that was being used in every faucet in the country — that would be a very tricky thing to do.”

Water companies use reservoirs and elevated towers to keep water in reserve, and batteries are the equivalent for solar energy. Now that solar panels (for example: GOAL ZERO NOMAD 20 )
 are becoming more cost-effective and efficient, it’s crucial that similar improvements are made to battery technology.

Our ongoing transition from fossil fuels to renewable energy is good news for the planet, and for its population. However, figuring out how to handle periods when the sun, wind, and flowing water aren’t easily harnessed is essential if we want reliable access to electricity. We’re on the right path, but the more we depend on renewable energy, the greater the challenge.

How can I possibly forgive him?

Despite how it might appear impossible, forgiveness is a crucial part of recovery for the partner of a sex addiction treatment. To forgive is not to forget. Forgiving means being able to remember the past without suffering from the pain all over again. It's recalling -- but attaching different beliefs about the events, and it's a willingness to permit the pain to get decreased relevance with time. Knowing the pain, compulsion and despair that the pornography addiction help has undergone from sex addiction counselors can open avenues to compassion.

To forgive is important primarily for oneself, not for the person one forgives. The opposite of forgiveness is resentment. When we repent, we experience the pain and anger all over again. Serenity and resentment cannot coexist.
sex addiction therapist

The practice of forgiveness begins with acknowledging that a wrong has been done to you. You have to recognize that you have strong feelings about what happened and you need to feel and process those feelings. You're entitled to be angry or hurt. Ideally, you can share those feelings with the person that has hurt you in couples counseling. If that is not possible, then you're able to share the feelings with your therapist or support group. After that, you can choose whether to remain in a relationship with that person. In either circumstance, forgiveness does not imply permission to continue hurtful behaviors. As part of your own treatment, you want to decide which behaviors you can accept in your relationships and which you cannot.

The principal aim of forgiveness is to heal yourself. In a partnership affected by sex addiction therapist, forgiveness is aided by evidence of the partner's changed behavior and commitment to treatment. These are also elements in rebuilding trust. For many couples, forgiving and learning to trust again go together. Both take time, making amends, continued treatment and steady, continual, trustworthy behavior on the part of the addict.

After the acting out has stopped, it's critical to not use his previous behavior as a "hook" to punish or manipulate him. When a desire for revenge exists, you have not forgiven, and you see him in one dimension ("Bastard"). The capability to see him as a whole person (he's not only sex addiction counseling, he's many things) will help you move forward. Couples therapy can help you move toward a sense of him as a multidimensional person with ongoing issues.

Portable solar power

As the cost of solar cells has declined, the industry has started to increase the physical size of individual solar modules. This not only has reduced manufacturing costs, but, because of the larger modules, has also reduced the number of field wiring connections needed to install the same size system. This market trend has also increased the weight of each module and the size of the aluminum frames and heavy tempered glass.

Smaller wattage solar modules ( for example: GOAL ZERO NOMAD 100)  first manufactured during the 1980s for off-grid and battery charging applications, are becoming harder to find as manufacturers have rushed to supply the faster-growing market for larger residential and commercial systems. In addition, as module sizes have increased, the 12-volt DC nominal voltage (actually 16 to 17 volts) standard that was first used with smaller modules was too low to handle the higher wattage of these larger modules.

Most modules over 125 watts now have a nominal 24-volt DC (actually 30 to 39 volts) output that is too high to directly charge 12-volt batteries or power most low-voltage DC devices. In addition, solar charge controllers that can match higher-voltage solar modules with lower-voltage batteries are expensive and sized for much larger systems. This means it can be a challenge to find smaller low-cost solar systems suitable for charging 12-volt batteries and re-charging 12-volt electronic devices.

Although smaller 12-volt solar modules are becoming harder to find and cost more per watt than larger wattage modules, you can now buy portable fold-up solar modules with built-in voltage regulators specifically designed for charging 12-volt batteries. This means you can connect these fold-up solar modules directly to a battery without the need for a separate solar charge controller or other electrical components typically needed for a fixed solar installation.

Several years ago the largest fold-up solar modules available were under 5 watts, about enough power to keep a cell phone or iPod charged. However, non-glass modules which can be folded-up to the size of a small book are now available in larger 25- to 30-watt sizes, which will easily power a laptop computer or keep your boat/RV battery fully charged. A portable 12-volt DC module with a 25-watt rating can provide more than 2 amps of output in full sun, yet can be easily folded up to fit in your car’s glove box or a camping backpack when not needed. A module this size can keep your fishing boat’s trolling motor or laptop computer battery fully charged in addition to recharging your cell phone and iPad.

Fold-up modules typically include a metal grommet in each corner, making it easy to tie on the hood of a car or deck of a boat, or to suspend between two trees when camping. Fold-up solar modules are advertised as having a rugged construction and long-life, but I am not sure I would use these for permanent installations or where these would be subject to months of hostile weather. However, including one of these flexible modules in a bug-out bag or as part of your emergency preparation supplies is almost mandatory these days.

Many of us would feel helpless today without our cell phones, iPod’s, Kindles, Nooks, laptops, iPads, digital cameras, email devices, and portable radios, and since we can easily recharge these devices in any nearby wall outlet, we never think about their limited battery run time. In fact, most of these electronic devices will be totally useless in less than 24 hours if we suddenly find ourselves without utility power for recharging. Of course, if you have to evacuate due to a fast-approaching wildfire, hurricane, tornado, or chemical spill, packing all these electronic books, videos, and games may not be your first concern. However, taking along a cell phone, portable radio, and a flashlight will keep you in communication with the outside world and make life much less threatening during a crisis, assuming you have a way to keep them charged.

Of course you could pack a ton of “AA” and “AAA” batteries, which will keep most portable radios and flashlights operating for weeks. However, today’s cell phones and portable computer devices utilize built-in high-capacity battery packs that cannot be replaced. In addition to having varying voltages, most of these built-in batteries can only be recharged using a special power connector and battery charger.

Designers of these portable electronic devices know that most daily recharging will be from a 120-volt AC wall outlet, but utility power may not be available during emergencies or on a camping trip.

All of the portable solar modules represented in this article include a large complement of DC plug adapters and a “female” 12-volt DC auxiliary car (cigarette lighter) outlet. This means it is now possible to recharge almost any electronic device that includes its own 12-volt DC car charger.

Most of the adapter cables supplied with each fold-up solar panel will also include a set of large spring clamps to easily attach to your car or boat battery terminals for emergency recharging. Of course solar modules cannot charge your batteries at night, so if you find yourself stranded with a dead car battery, you will be waiting for sunrise before getting back on the road!

If your emergency power needs are limited to portable radios and flashlights that still use “flashlight” batteries, I found a really great battery charger called AccuManager that can recharge all sizes of flashlight batteries, including the rectangular 9-volt batteries typically found in many portable radios and electronic games. What I really like about this charger is that it has electronic charger controls that will sense what type battery is inserted in any of the multiple charging slots and will separately adjust the recharging voltage and current for each specific battery, and charge multiple batteries at the same time.

This is a great feature since Ni-Cad, Li-ion, and NiMH rechargeable batteries each have a totally different charging cycle. Of course, this means you will need to replace any expendable batteries in your devices with the more expensive rechargeable batteries, but you now will be able to operate these electronic devices and flashlights almost indefinitely using solar power and this battery charger.

This charger also includes its own 12-volt DC plug which exactly matches the adaptor cable furnished with these fold-up solar modules. Although this charger is very lightweight, it is still too large for a tightly packed bug-out bag, so it is more suitable for RV or remote cabin use.

The criminal world is also starting to realize several thousand dollars’ worth of solar modules will easily fit in the back of an old pickup truck, so theft is becoming a concern for owners of solar modules mounted on remote cabins in sparsely populated areas. For this reason, I am getting calls from people looking for a solar array they can easily move outside during weekend use or a power outage, and then bring back inside when they leave or the utility power is operating again. This is a great application for fold-up modules since several can be wired together to increase capacity and temporarily tied down on the south-facing roof of a cabin, woodshed, or storage building.

For example, combining the output of four 25-watt fold-up modules will produce more than 8 amps of 12-volt DC power which can recharge two deep-cycle 6-volt golf cart batteries. When wired in series to provide 12-volts, these batteries can power a small DC to AC inverter that will power a microwave oven, television, or small well pump. This portable solar power system will also have the capacity to power multiple low-voltage lights in a multi-room cabin or RV. For extended run time, I would first convert any 12-volt DC fluorescent or incandescent light fixtures you are using to 12-volt LED lamps, which will allow your battery charge to last up to four times longer.

Since most of the larger wattage fold-up modules can cost more than $200, there are several low-cost alternatives if you only need solar power for emergency lighting. Solar-powered lights for camping are now available for less than $65. They are lightweight and will easily fit in a bug-out-bag.

I like the portable solar light shown in the previous picture, as this fold-up desk lamp fits into slots on the back of the included solar module for packing. This model includes a long connecting cable so the solar module can be placed outside a tent, car window, or cabin, while the light can be placed by a nearby desk or bed. This light also includes a built-in photocell which turns the light off during the day to save battery drain in case you forget to turn it off. Although not much larger than your fist, this miniature desk lamp is very bright and will run many hours on a charge.

It is now much easier to find a solar-powered battery charger in a size that fits your budget and emergency needs. However, it is important to take inventory of all electronic devices you now own and decide which ones are absolute necessities to operate during an emergency. I recommend shopping for a car adapter charger that fits more than one device.

For example, although my wife and I have different brands and models of cell phones, I discovered they both have the same charger plug and can use the same charger. When I purchased a portable radio and several LED-style flashlights, I selected models that use the same size and type of batteries. This simple plan will make it easier for a single fold-up solar module to charge multiple devices, and will help reduce the need for multiple chargers, batteries, and adapter cables.

Remember, during an extended emergency, all of your cell phones, laptops, electronic devices, and flashlights will be totally useless after the first day if you have no way to recharge them, so keep this in mind when planning for your family’s safety.

Defining Business Blogging Success

Defining Business Blogging Success

When talking with blog or M&O Account Teams about new clients, it is inevitable that I will ask if there is a blog involved. There are simply too many advantages to enabling a web site with fresh, themed content that is well structured for SEO benefits and that also offers a great platform for creative promotion, not to consider it in the online marketing mix. However, the mis-perceptions about what a blog is and is not abound, even with self-described “blogging experts”.

Despite that, I think it’s a perfectly reasonable question for a company to ask: “Why should we have a blog and what will it do for us?” Answering that question in the most effective way possible starts with understanding the business and marketing goals of the company. Too many SEOs and blogging consultants focus on the mechanical capabilities of a blog and not on the business goals that can be met.

Blogs are simply tools and are only as effective as the programs and people put in place to use them. The degree to which company goals can be met with the applications and current/future benefits of a blog are what we use to determine whether a business blog is appropriate or not.
