All Sw1 and Sw2 switches in off position. Using Toslink module, linked to D1 and ground. Lock led is lit. Music is muffled. Any ideas what i am doing wrong.

The relay is 24 volt (+-12v equals 24 volts measured between the rails). What are your readings out of the powersupply for the IVY. Measure between: 1: v+ and gnd 2: gnd and v- Edited by user Wednesday, February 29, 2012 1:26:25 PM(UTC)  | Reason: Not specified

I read both manuals for the power supplies, but had set the voltage on both to 5.25v, Missing the IVY voltage setting of +/-12v so it is little wonder that a 24v relay would not pull in at 10.5 volts.
