ChenL Black Bluetooth 5.0 Amplifier sku-17149073903

The ChenL Black compact HiFi power amplifier is listed under Home Audio, Speakers & Soundbars as SKU sku-17149073903. It supports Bluetooth 5.0, USB music playback and selectable 2/4 channel operation. Four speaker output groups can connect up to two pairs of passive speakers or active speakers, and each output has its own volume control.

The amplifier has two wired stereo RCA inputs and works with sources including phones, computers, TVs, MP3 players and CD players. Its U-disk player supports MP3, WAV, APE, FLAC and WMA files. Used as outputs, CH3/CH4 provide four speaker sockets for two pairs of speakers. They can also feed an M4 amplifier to distribute one signal through multiple amplifiers and speaker sets across several rooms.

Used as inputs, CH3/CH4 route signals to their corresponding outputs; for example, a CH1 input signal plays through the CH1 speaker socket. This allows two stereo sources or four mono sources to be used at the same time. Maximum rated output is 50W*4. The supplied 24V/4.5A power adapter is described as capable of driving most home speakers.

The unit uses a compact circuit layout, concise wiring and components described as intended for clear sound and stable operation. Small- and large-signal circuits are separated for protection. Its Bluetooth module is built in without an external antenna.
