SCHEMATICS for v372D needed PLEASE

[[silent:arts]]

There are no power ratings on any of the schems, neither for diodes, caps, resistors, etc

Well, just use 1N4007 for Diodes and 35V rated caps.

Ok. thanks for that

"Pos" is positive, right? (24v)
What about "Fix"? Is that the feed for relays?
What would you use relays for?

Cheers

POS can be 24V, in your case should be the 24V for the V372D cards

What about "Fix"? Is that the feed for relays?

FIX is a utility "fixed" source for relays, meter lamps etc.
To avoid a lot of heat use a TL7824 and 24V relays.

What would you use relays for?

Pad. Polarity Reverse. Mute. Bypass. Things like that.

Thanks for your patience and excuse all these questions but I'd like to understand it all and there is a part that escapes to me.

Please correct me if I'm wrong. 

- the 24v secondary of the transformer goes to "AC" on your FP48PSU
- +24v pin on the v372D goes to POS
- +48v on your FP48PSU would be connected to your MIO where it says 48v (pin 4)
- All GNDs are connected together to the pin marked GND on your FP48PSU except audio gnds (pin 1) that should be connected to chassis.
- If I understand correctly each relay positive (24v) goes to each marking "pad" and "phase" on the MIO board and the relay gnds (pin 3 on the MIO) with the other power gnds to "GND" on the FP48PSU.

If all the above is correct I still need to know if the Pad and reverse circuits are on the boards or have to be added. If they are on the boards where do the switches go? Any special needs for them? If they have to be added can you tell me what circuits would work?

Thanks a LOT for your help and time
Sono
