• Turn on power switch. Clip, Limit, and Signal LEDs should stay lit for approximately the first 15 seconds, after which
the amplifier should be fully ready for operation. The amplifier's LCD screen will show the firmware version screen after
about 10 seconds, then revert to the operating screen.
• Check power cable, ensure retaining clip is in place.
• Check mains circuit.
Check the LCD screen for output meter activity. If no signal activity, check the following:

• Check that Output Attenuate is not set too low.
• Make sure loudspeakers are wired correctly to output connectors.
• Check that Output Configuration is set correctly.
• Check that Standby Mode is not active.
• Verify source level by monitoring Input Meter. Check that Input Routing and Input Sensitivity are set for optimal gain.
