Advanced Applications
Remote Turn-on
To operate an amplier 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 amplier in standby. Floating the FAULT FLAG or connecting it to ground turns the channel on.
Fault Reporting
To have an amplier channel report a fault to a control system or back up amplier, 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).
