2.1 Channel BT Audio Amplifier Module AUX BT5.0 Audio Input Subwoofer Left and Right Channel Output Sound Power Amplifier Board no matter in which mode BT can be connected, as long as BT connection is successful it is BT mode, and BT mode supportsautomatic back to . R&L CHANNEL-TREBLE knob is to control treble,right turn treble enhancement, left turn treble decay. When knob is in middle position, treble is not enhanced and not attenuated. SUBWOOFER-FREQ knob is tocontrol subwoofer cut-off frequency. frequency of right rotationincreases and frequency of left rotation decreases. Frequencyadjustment ranges of 20Hz-200Hz. BT no connection when AUX is inserted is AUX mode, it shouldbe noted that when using AUX mode, you need to confirm that BTconnection of this module has been disconnected. Adopts low noise preamp, shielded inductor, large capacity energystorage capacitor and 3116 amplifier chip, can provide stable and quickconnection, with wide compatibility. one is BTinput mode, another is AUX input mode, BT mode priority. When knob is in rightmost position, bass is not enhanced norattenuated. SUBWOOFER- knob is to control volumes of subwoofer. volumes becomes louder with rightrotation and smaller with left rotation. MAIN- knob is to adjust main volumes, right rotation of main volumes increases, left rotation of main volumes decreases. main volumes has an effect on volumes of both left and right channels and subwoofer. over-voltage, under-voltage, overheating, direct currentdetection, short-circuit protections, safer to use. R&L CHANNEL-BASS knob is to control bass, right-hand rotation bass enhancement, left-hand rotation bass attenuation.
This is a BT audio amplifier module with high and bass independentadjustment, BT + AUX audio input, dual-channel stereo output, withoverheating, overcurrent, short-circuit protections mechanism. higher supplys voltage higher output , smaller speakerimpedance higher output .
