Remote Turn-on
To operate an amplifier channel in low power standby with remote turn-on, set its rear panel switch to SLAVE. External +5 volts con-
nected to the FAULT FLAG holds the amplifier in standby. Floating the FAULT FLAG or connecting it to ground turns the channel on.
Fault Reporting
To have an amplifier channel report a fault to a control system or back up amplifier, set it to Master. °e
Fault Flag is held high (+5 volts) during normal operation and goes low (passive pull down) when a fault
occurs. For details on Fault Flag operation, see page Manual-3.
Remote Level Control inputs are provided for each channel. °e Rane VR 2 or any other linear potenti-
ometer 10k to 100k Ω may be connected to these inputs (diagram at right).
