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 👍 ## Features - Adopting classical TPA3116 amp IC, class D amplification, max output power can reach 100W(4Ω load), easily to drive all home bookshelf/ computer/ desktop/outdoor passive full-frequency speakers and match perfectly with them. - With 3.5mm AUX audio input, perfectly compatible with many audio devices such as phone,TV, MP3, CD players, computers, DAC etc.. With built-in preamplification circuit, can match well with the audio sources that with low signal output. - Reasonable circuit, concise wiring layout and perfect protection, no sparks no shock. Adopting NE5532 op amp with ultra-low distortion, the sound is very smooth and natural, powerful in low frequency and delicate in high frequency, full of music styles. - Mini size with exquisite appearance, aluminum alloy black case looks fashionable and attractive. With strong output power and high-quality sound, especially designed for the customers who pursue HiFi sound. - Warm tips: 1.
