There are occasions when the volume control on the switch needs to be taken out of the picture entirely — most commonly when a zone is feeding an AVR that will handle its own volume. This covers setting a zone to pass audio straight through at a fixed, unity level.
- Locking the volume control on a zone
- Disabling the switch's volume control when using an AVR as the amplifier
- Passing audio straight through the switch without changing the volume
Setting Zones to Pass-Through Volume
Set the affected zones to 200 using the VZ command — this is always unity gain (no boost, no cut), regardless of the zone's Min/Max Volume settings:
^VZ @1@5:8,200$ ; set zones 1, and 5 through 8, to pass audio straight throughThen save this as the new power-on default using SS:
^SS 256$ ; save the current volume levels as the new power-on defaults^SS 256$ saves the current volume of every zone, not just the ones you just changed. Before running this, make sure all your zones are sitting at the levels you actually want as their defaults — otherwise a zone you happened to be testing with will come back at that level after a power failure, not its usual one.Keeping the Volume From Changing
Setting a zone to 200 only stops the switch from applying gain — it doesn't stop something else from sending a new VZ or VPZ command later. Make sure your control system isn't set up to send volume commands to this zone. In an AVR setup, the AVR should be the thing your control system adjusts for volume — not the ProAudio switch.
