CF82E35 Echo Switch Unit >solved<

[mad hias]

Hi guys,

Can anybody tell me what the CF82E35 Echo Switch Unit does? Is that an option like Local Aux? I found schematics in my console service manual but I have no idea where this card is located (it's not in the SL 651G Center Module) nor do I know, if I even have one in my console (4064 G+).

Any hint is very much appreciated!

Cheers,

Matt

If anybody is wondering the same: It's a small pcb with buttons, which is connected to the CF82E30 Stereo Echo Return card.
