Loved using this to run room EQ, made things so easy. The result was a very smooth sounding mix and the band was amazed how good everything sounded. I'm expanding my usage now going through my powered systems and aligning them as well.

This was purchased for a church to help rid feedback on the mics and it works great!  Additional after seeing how awesome the preset eq feature works I pulled a 31 band eq from my rack because this works so so well.  We bought this in conjunction with a new set of main speakers thinking we were going to need to get a sub woofer. But when we engaged the sub synth feature all I can say is Wow! No need for a sub woofer now saving around $1k.  For our needs this little Gorack has done everything expected and hoped for. The ease of use is huge too as we are not professionals just volunteers.  Thanks for a truly great product.

I use this to mix 3 computers I use at work, one is a microserver and the other 2 computers are for video editing and general work.

My problem was that, I wanted to hear my microserver alarms and notifications, and at the same time, I wanted to hear what I was edting on my 2nd and 3rd computer. To mix all signals you have to use a mixer, you can't just use Y adaptors, you will kill your outputs.

Before buying this mixer, I was connecting and disconnecting each computer from my hi fi stereo system. With this mixer I solved this problem. Also, my main sound card hasn't the same level of output, its very underpowered, so volume pots are a must have in this situation.

My only complaints are:
1-I forgot to turn it off once and the rechargable battery was at zero the next day, so I had to recharge it. Of course, this until I get the AC power supply. My batteries are 550mah li-ion and the work perfectly fine with this, I use maximal power brand and they are fantastic for guitar pedals, but take into consideration that they won't last a lot on this mixer.

2-The other complain is that you should turn up and down both left and right pots to change volume of each channel. Its uncomfortable, but hey, I found the device very cheap for what it is.

Working great! Love the sound this puts out. It has many more features than I use. The Android App could use a bit of refinement, but it works and does what it is supposed to do.

I use in a 5.1 plus setup -- 4 speakers up front, 2 monitors and 2 wide high. The Audisey sound tuning is great, it automatically figured out the speaker configuration, and it really balanced the room out and helped since my room isn't perfect.

Works fantastic for my application.  Father-in-law purchased a new tv and wanted better sound.  Some of his old stereo equipment was not working or partially working.  Bought this little amp and hooked it up to the TV headphone out and went to the amp input, this way the TV remote can still control the volume.  Used his existing front bookshelf speakers and a little powered subwoofer with speaker level inputs/crossover and it works beautifully.  Sound is much more full than the TV could produce and it can get a bit louder than the TV alone.  We set the Lepai-2020A+ to about 50% and the bass and treble at about 50% and use the TV and sub to adjust the type of sound they wanted.  Mounted the amp in the cabinet behind the TV and it is out of the way and works great for this application.  They can even pivot the TV and turn it up loud enough to watch from the kitchen.  I am sure there are many other ways to accomplish a similar if not "better" sound system, but with limited space, need for simplicity and budget friendly, this is a good solution for our application.  My mother-in-law smiled when she heard the difference between the TV and the "amped up" sound.

We had a Yamaha from 15 years ago that was still good but the sound was not set well for the Bose speakers we have.  We plugged this in and used the microphone to adjust the sound and it has made the room quality go over the top.  I would recommend for any system you want to maximize the sound levels to your personal area.

I was fooling around after I set the knobs for a cheepy gu itar I have and was impressed how bold  and beatuiful it sounded. So, I ran the unit thru the Insert channel on my little pa effecting every thing running thru the pa. I left the graphic eq flat and the sound was so good I had tears in my eyes it was like the sound permeated the room. If lost or stolen I would scope out aphex again.

This worked great to add mic inputs to a ultra small form factor PC that only had headphone jacks. The sound quality is great and the DSP to add extra control in games was great. My son loved this unit and I thought the sound quality was on par with anything else i've heard in the PC world.

I love my Qu-Pac. I was quite surprised how much better my electronic drums sounded (This is what I use it for) over my old Mackie 1402. I thought the Mackie was fine but now I have a slightly different opinion about the Mackie. Granted, this unit is 3 times the price but the built in DSP is top notch, I wouldn't think twice about using it in my professional setting. The EQ sounds great and all of this is recallable as well as the 10 assignable outputs. PERFECT for gigs where you get anywhere form 1 to XX channels. With the Qu-Pac, I can sub mix any set of channels I want and send them to the board out front.
It does take a little time to figure out so don't buy it on your way to a gig! I just read a review on a similar product where the person did exactly that and complained later. he he......

It is very unusual to find a small, light EQ, particularly one with as many level, volume and filtering options as this one.  It won't take too much knocking-around so care should be taken if used for travel, but it's nice to be able to have this much control with portable sources.

Received this as a gift for Christmas this year. I love this.
In playing around with it so far I have hooked it up to my Tascam DP-008EX ( https://www.amazon.com/DP-008EX-Portastudio-Portable-Multi-Track-Recorder/dp/B00B9060X6/ref=sr_1_2?s=musical-instruments&ie=UTF8&qid=1482944465&sr=1-2&keywords=tascam+dp-008ex ) I dialed the sound in, AND THIS WAS CLEAN. I heard no buzzing or even much background noise. (I wasn't in a booth) My voice came out crystal clear and strong.

I bought this to have something to power a couple of Bose 301's while my reciever is in the shop. I got a TV plugged into one input and a bluetooth reciever into the other to listen to mp3s. It's been running 24-7 for a couple of weeks without a hitch. I can get it to about 2/3 volume before the distortion gets noticable. Thats plenty enough to tick off the guy upstairs. When the reciever is back I'll put it in the garage.

I was looking for a surround system for the living room remodel I'm doing and this guy fit the bill nicely.  I love the gadget that lets you automatically set up the sound system settings for your particular room.  In fact, because I have an odd shaped room with 12' ceilings, it was a big selling point for me.

I didn't use the center speaker.  It sounded fairly impressive for what it was but I upgraded with a Klipsch Reference Series center speaker.  Also be aware that the electronics that Yamaha chose to use for the "on/off" function causes problems with the DirecTv remote control... and probably with others as well.  Yamaha uses a simple toggle on/off instead of discrete on and off functions.  This means that you can't program a DirecTv remote to control the on/off function... at least without jumping through hoops.  There is a bit of a work around which allows me to control the receiver from DTV remote but it does involve pushing a few more buttons to turn the thing on and off.

I spent a long time looking at this system, debating about how it would work for my set-up. I have an old home with hardwood floors, there was no great solution for running wires or placing rear speakers, so that ruled out true surround. Looking at the various bar systems, I wanted a sub and didn't really trust the high-end systems to satisfy me. I placed this guy on my wishlist and waited for a gift.

I've had it set up for a week or so now. My first impression is that this sounds so much better than television speakers, the sub adds a lot of richness. Several people complained about the high-end volume levels not being loud enough. I honestly think they might have either faulty systems or not set it up right. Granted my room has no carpet, but I sit 12 feet away from the system and at about half it's full power, it's pretty loud. You CAN adjust the balance between the center speaker and the sub so that as you turn up the volume dialogue does not get washed out by bass.

All in all this is a great solution. There's no true surround effects, but things go boom now and it can fill the house with sound.

I just bought one of these as a secondary PA to serve as either monitors to my JBL/Yamaha main system or as a 'secondary room' system which is the real reason I became interested (so many gigs suddenly inform you that the ceremony is somewhere else or they need sound upstairs too etc) I bought it and actually prefer to play through it for practice due to the great sound at medium and high volumes and portability. I have used it twice for the secondary room scenario and use it at home in favor of the bigger PA to practice with.  The thing sounds great at any volume and can really get the job done for smaller events. I recommend the passport series wholeheartedly.

I use it to control the various desk speakers, headphones, and a subwoofer.  Clean sound, and tough.  I've had this rig at least a couple of years.

This is the second unit I've purchased and I love it. Amazingly inexpensive, it's a perfect home device. You can configure each channel (8, or 4 stereo) to split off of the main input, or combine (mix) into the main output. Each as level controls (see the manual) that make it flexible for enough for a small home studio. I have audio out from my computer, synthesizer, and sometimes guitar and electric violin. I route outputs to a home stereo, studio monitors, headphones, effects processor, small guitar amp, and etc. The separate gain controls makes it possible to match impedance levels without  separate DI boxes (although those are still useful sometimes)

(The first one was several years old (maybe 10?) and suffered in my last move. The old one still works as a mixer, not as a splitter. I started noticing crackling and drop outs. Fair enough after years of being left on all the time)
