🔊 Nobsound 100W Full-Frequency Mono Channel Digital Power Amplifier Audio Mini Amp for Home Speaker, Including Power Supply (Black) Review

The product works well, especially considering its small size. Perfect for the active center channel speaker system I had in mind.

Even more power when operated via your own 24 V DC power pack 100 watts only with 24 V supply. Much energy. No bass or treble controls and no RCA inputs, which I thought was a compatibility issue, but I bought the necessary mini-cables.

I used this to boost the sound for a medium sized speaker I have and ended up removing it from the equation due to the hum and piercing high pitched sound . a tonal note that kept ringing. Noise and ringing persisted (1) even after disconnecting the 12V DC power supply (deep cycle battery) and (2) even without any input. Once I took the amp out of the equation, the sound was perfectly clear. true, softer :) Maybe this amp is only for subwoofers?

A lightning strike paralyzed my home theater and both Yamaha amplifiers. Fast forward a few years and I bought a Yamaha ATS1080-R soundbar pretty cheap. It has internal subwoofers and honestly sounds good for a soundbar but not like a dedicated subwoofer.

At first I thought I'd redo the amp from the inside, but it's part of the…

#1) The 19V power adapter that comes with this unit is not enough for the advertised 100W. You will need a 24V power supply, but you won't find this in the documentation until you've purchased the product. I would recommend that you buy the model without the power supply (is a few bucks cheaper) and then buy the 24v power supply itself. . I had NOT connected any speakers yet, but I could hear sound coming out of the box. There are no speakers in this box. I don't know what is creating this…

I've tried it as a guitar power amp, from a preamp pedal to a mixer to Nobsound and to a 15" speaker cabinet. I measured some decibels using a phone app and this amp was able to push the speaker to around 120dB peaks - pretty loud. There was some distortion to keep this loud though. This was tricky because this amp has a lower input sensitivity than I'm used to with most instruments, so I really had to turn the mixer output down (about -20 to -15 on the master meter). However, it was fairly…
