At a Glance
- Senses trigger voltage as low as 0.8 V
- 12 V output with one-second delay
- Supports appropriate speaker-lead or remote-wire triggering
Compatibility & Installation Requirements
Verify the source circuit, ground arrangement and load against the PAC instructions. This module supplies a control trigger rather than amplifier operating power.
Check the connected equipment turn-on requirements. A delayed trigger can address turn-on transients, but correcting a ground or wiring fault may also be necessary.
