so what exactly do i have to populate at the bypass pcb?
One-by-one.
at the moment i have 24v relays + diode with solder jumper at series connection.
In case of 24V relays, the connection should be PARALLEL, 2 jumpers.
/not the central one, those which right down the relays/
solder jumper at ING.
Connects input xlr pin 1 to case
Right, we shorting the bypass switch on bypass pcb and feeding 24V from EQ pcbsolder jumper at 1+2 at bypass switch 3pin molex (is that right?),
vrel1 2pin molex connected to byp on eq pcb,
Right, 24V from front PCB to bypass board
2-pin Molex marked "24V" on EQ board goes to power supply, 1+ 2-
and input / output 3pin molex wired with the makeup ba283, no rled installed.
Rled on bypass PCB is out of care
3-pin Molex:
IN goes to IN, OUT goes to OUT at make-up PCB
groundplane on bypass pcb to case!
Yes, right!
i measure 24VDC at pin 1 of 2pin molex vrel1
when switching the eq bypass switch either up or down.
I assume 3 position switch ON-OFF-ON used. This way, up is eq+makeup,
center is bypass, down is makeup without EQ.
Let's do next. Connect 24V to bypass board, to VREL, 1+ 2-, and see if bypass works.
Pins 1+2 at 3-pin Molex, BYP_SW, should be shorted.
