Can support 100W (ba channel) + 50W (left channel) + 50W (right channel) three-channel output. Support Bluetooth audio receiving, external audio source input interface, with preamplification, ba frequency division proceing; ba volume, ba frequency, left and right channel volume, treble, function control switch / total volume, 5 adjustment potentiometers. Wide operating voltage, power-saving design, efficiency up to 90%.

The main product parameters: Size (L * W * H): 101 x 100 x 25mm, excluding potentiometer and socket projection Operating voltage range: DC 11-25V (current 3-4A, or 19-24V / 4-5A, such as high power requirements 20-24V / 8-9A above) Note that the DC no-load voltage should not be greater than 25.5V. Bluetooth receiving distance:> 8 m (meters) Audio input sensitivity: 600-800mV Frequency response range: 20Hz-20KHz Speaker impedance: left and right channel speakers: 4-8 ba speaker impedance: 2-8 The output power is related to the supply voltage/current, the speaker impedance, and the size of the audio input. When the power supply voltage/current is sufficient, usually the power supply voltage is higher and the relative output power can be made larger. Speakers with different impedances have different output powers. Usually, the speaker impedance is smaller and the power is easier to achieve. Function switch Instructions for use: 1. Plug in the power on default Bluetooth mode 2. Bluetooth disconnected, long pre the switch can switch to the audio input mode 3. Bluetooth play status, short pre the switch to pause / play
