Q: does this have subwoofer output?

demandé par Samu245 sur 2019-01-23 05:57:59

TiemeKuyper No, is has 2 stereo outputs which are already bridged, so not bridgeable for SW.

TiemeKuyper The output is connected to the input on this implementation causing terrible distortion. If you remove "CA" and "CB" (silk marking on the PCB) and connect the audio jack lines using a series 47kΩ and 4µ7 to the - inputs of the opamp (pins 2 & 6) then there is correct analog audio. I also increased the mute C (close to R21) to 33µF to reduce start pops and increased the input R's for the BT module (R1, R2, R5, R6) to 100k to reduce the hiss of the BT module. Working nice now.
