Digital Designs Z1 repair
My DD Z1 broke down.

The loudspeaker relays remain off.
Does anyone have schematics or details on how the coils of the loudspeaker relays are controlled?

Thanks in advance.

On z1, relay control is on secondary board, where pwm for power supply is. On pin 18 comes remote, and relay pin is on 7. So look at those signals.

What about leds, any indication that there is really something wrong with the amp, or only relay part doesn't work?
