Stereo Audio BTL to XLR Balance Converter Adapter Processor Board DIY Kit
100% Brand New and High Quality
Note: this item is DIY Kit , not assemble. buyers need to welding it .
PCB Size: 70*33mm
Using inverting buffer design, two-channel BTL bridge board.No signal distortion, no signal gain, completely lossless signal output
Dual Channel Balanced Output, BTL Preamplifier Board.
Ordinary two-channel input signal RIN RGND LIN LGND
Output R + RGND R- L + LGND L-
Can be used with ordinary two-channel amplifier to form a balanced (bridged) monaural amplifier.
Power increase four times (at the amplifier output current capacity is enough case)
Connection: one channel (another channel is the same)
XLR balanced preamp output + connected amplifier left channel input +, output GND connection amplifier two channels of input GND.
(The general amplifier two channels of the input are connected together, connect a channel of the GND can be)
Preamp output - connected to the right channel input +.
And then two-channel amplifier connected speakers, amplifier left channel output is + signal, connect the speaker +. Power amplifier right channel output is - signal, connected speaker -.[Amplifier before the unbalanced connection is that the left channel output + connected speaker +, left channel output GND connected speaker - and the balance after amplification, the amplifier output of the GND is empty does not take]
Wiring diagram: Please refer to the main diagram.
