Rated 5 out of 5 by from A great amp !! Work excellent !I bought this unit about 2 weeks ago. I'm very pleased with its performance.I would definitely recommend this product without any hesitation. Thanks for offering such a great product !

Rated 5 out of 5 by from Good replacement for older ampsI got tired of repairing the two driver boards in my Sansui 5000X. I bought the Sansui receiver/amp in 1971 so it holds sentimental value for me. This little amp fit very nicely in the 5000x chassis after removing the driver boards and capacitor banks. I had a 12volt, 4 amp SMPS that fit the underside of the Sansui chassis.At this price point, this little amp can't be beat. Although mine only delivers aprox. 48 watts it drives a pair of ESS AMT PS-820 speakers with ease. Those with less efficient speakers would want a larger voltage/current PS.Products quality is outstanding and parts placement is well thought-out.No knocks for this product so far.

Rated 5 out of 5 by from Very Good soundI have 2 tuba amps which costs several 100 euro each.But this amp seems to beat them.....Never expected this quality.

Rated 5 out of 5 by from very nice amp - runs cool and quieti'm using this with a switch to turn on eight speakers (2 at a time). it is really more than i had expected. need to look into the factory tuning mentioned here - will probably pull off the heat sink and take a look.i got some good advice from an engineer at parts-express too. just having 60 seconds to run an idea by someone was worth a lot.

Rated 5 out of 5 by from Stage monitor amp.Got one of these from a friend. I had a all 2-4" speaker stand mount personal monitor filling a dead spot. Added this amp and an Load. Perfect. Clean and reliable.

Rated 4 out of 5 by from Wow this sounds niceI docked it a star because the volume control does not work with it (sold separate). I docked it's features because it has no gain control. Previous models have more features, features I wanted. That model is 14 v and wouldnt work for me.That said, this thing is ridiculously nice. You will land up tuning the DC offset. out of the box one side on mine was tuned perfectly, the other was at 40mv which is pretty far out. At 50mv you can hear it, and above that you may damage your speakers. This also accounts for a feature star being removed. You need to remove the heatsink to tune it , the directions say its factory tuned. It is not. It still sounds out of hand good before tuning it , but it should be tuned as the factory says it is. This is sure, not PE dropping the ball and PE should be speaking to them since they are not doing it.In the big picture this is of tiny importance unless it is farther than 40mv out and you can tune it. For the money this is a small price to pay for the amazing sound this amp makes. Granted I have some really nice speakers but as others note it does a nice job even with homemade speakers.Highly recommend , as long as you dont mind no volume control, its perfect for a Pi or mp3 player or what ever you want amazing stereo sound in.Even the box tells you it is nice.Ideally a 12 v version that accepts the volume control would be available , for my use case but this worked out perfectly in the end. You can control the volume in XBMC on the pi by hitting - or +. The drawback is it gets loud quick. For night time listening in an apt, I find the volume is usable for about 0-5% on the pi. Any more than that and its just too loud. For daytime listening it is 'loud' running 8 ohm speakers at about 30-40 %.The sound is seriously astonishing. If you have any hum it is not the amp, try a ground loop isolator.

Hi Sir/Mdm, Can I bridge the 2 channel become 1? Regards,

Asked by: furion828
Unfortunately this amplifier is not bridgeable.

Hi, I want to know if you can add a 12 volt out next to the power in? I have the correct connector. It would be like the other 2 x 100 Watt amp. Would it be 12 volt if I am putting in 24 volts? Michael

Asked by: Mpjadvo
If i understand correctly you want to input 24V to the amp and are asking if it will output 12V from the second power plug? Unfortunately no, it will only output the same voltage you are feeding into the amplifier.

May be a silly question but I was wondering if a basic printer adapter will work for this? The adapter is 30v @ 500 mA. Thanks in advance for your answer.

Asked by: CDub73
500 mA will be enough to power it up but will not provide enough current draw for much output. The power supply we recommend for this amplifier is no less than 5000 mA.

Hi, I looked up the specs for the TK2050 chip and it says that the outputs can be connected in parallel. Will this board allow me to do that? Thanks!

What else do I need with this amplifier?

What power cable do I need, what pre-amp do I need. How do I connect the blue tooth dongle to it?
Asked by: isanglitro
I'd go with 12-10 gauge power cable. No preamp is needed. You'll need a dongle with a 3.5mm stereo output, then a 3.5mm to male RCA cable.
