Post by Chris72160 »

Hello,

i have a very low signal on LA4140 pin2 (headphone-out).

ac offset values:

Pin1 1v
Pin2 3v
Pin3 3v
Pin4 3v
Pin5 0v
Pin6 3v
Pin7 6v
Pin8 6v
Pin9 3v


The main-out sound-section sounds great! :)

Any ideas? :(

The idiot (me) connected a 3,5mm headphone plug (iPhone-Headset) with such an 6,3mm adapter (see picture).

Because the 3,5mm plug wasn`t getting deep enough into the adapter, i heard nearly no sound.
