Review: Full Freq, Sums Stereo Input to Mono - This is a great little amp. I bought the full Freq version and a 24v 6amp power supply, have stereo Bluetooth as an input which is summed to a mono output by the amp. Output (banana plugs required) goes to two outdoor Yamaha wall mounted speakers wired in parallel (halves the speakers ohms) to give mono music (ideal for outside) all around the patio. Very powerful, very little, very impressed. Would buy a second one for another project in a heartbeat.
Review: Sub and full frequency mono amp - If you open the case, you can change the Jumper shown by red arrow, to swap between the two, make sure unit is disconnected from power before you change jumper. Circuit is labelled for jumper. The full frequency amp is on definitely on the bright side of sound, sub doesn't seam to have a high enough low pass filter, it could do with going over 150 to 250 hz for more usability 👍 Recommend for full frequency mono to a crossover, or cinema sub, not music sub. Highly recommend 👍

## Questions & Answers

**Q: Can you plug samsung phone into this to boost the output.**
A: You could do  and it would work. My Nobsound has two separate input jacks (rca) therefore if  you are  intending to use this to power two speakers. then you would be advised to get a 3.5mm phono jack to  two RCA plugs. I used my Nobsound to power a small 8" subwoofer  through a filter (to get rid of everything above 250 hze.

**Q: Could you plug a Bluetooth adapter into the aux with it being a stereo signal going into the amp from my phone and a single speaker from the amp ?**
A: Yes

**Q: My amplifier only has a 3.5 lineout for an active subwoofer. Can this unit be used with my passive subwoofer? Any recommendations?**
A: The low frequency version should work for you by amplifying your passive subwoofer from your stereo amplifier pass-through.
I have two of the full-frequency versions which I use in different rooms for powering mono centre channel speakers as tv 'sound bars'. One set up works very well but the other suffers from hum that I have not yet eradicated,. My experience chimes with reviews that suggest that these small amps can work well but are sensitive to ground-loop and interference issues in their set-up.

**Q: Can I use this to power a 70 watt with 8 ohms speaker?**
A: I think not. It should be like 50W @8 ohms
