Review on 🔊 Q100 Bluetooth Amplifier 80W+40Wx2, DSP BT 4.2 Digital Bass Amp with DC 24V 3A Power Supply, 2.1 Channel Mini Class D Stereo Audio Receiver, Wireless Home Theater Power Speaker Amp - Black by Brandon Gaines

I bought this amp specifically for Bluetooth connectivity to pair with Echo Point or a cell phone. Bluetooth range is adequate and easy to connect, but audio lag is extremely noticeable, making it impossible to use with movies or with other speakers (multiple setup rooms) or as a remote surround application. Output power with included power supply is less than 10W per channel (edit after 1 year of purchase, that's 5W x 2 + 8W sub at 5% distortion). with a roll-off to 120 (or so), making the use of a subwoofer mandatory for movies and other applications, is unnecessary for casual listening. if I had known that before buying, I would have chosen a different Amp.Pro; comes with cables and power supply, subwoofer level control and compact design. For average usage, 5 watts is more than enough (fills a medium-sized room), especially when paired with high-sensitivity speakers. minuses; With significant Bluetooth audio delay, the subwoofer channel is deprived of power for distortion-free use in movies and popular music. To edit. After a year of purchase without changing the 24V/3A power supply, the amp simply stopped working after 8 minutes, the problem was limited to the power supply. Adapter. for everyday this is not a problem, but for films for everyday it will not work.
