Front Panel Controls and Indicators
Bridge Mode Indicator: Yellow LED
illuminates when the
amplifier is set to “Bridge-Mono” mode.
Ready Indicator: Green LED, one
per channel, illuminates when the
channel is initialized and ready to
produce audio output. Indicator is
off when the amplifier is in standby
mode via the IQ system.
Signal Indicators: Three green LEDs
per channel indicate the amplifier’s
input and output signal levels.
Signal: Input signal is above –40 dBu.
–20 dB: amplifier output is 20 dB below clipping.
–10 dB: amplifier output is 10 dB below clipping.
Clip Indicator: Red LED, one per
channel, illuminates when the channel’s
output signal reaches the onset of audible
clipping.
Thermal Indicator: Red LED, one per
channel, illuminates when the channel has shut down, or is very near shutting
down, due to thermal stress or overload.
|
Fault Indicator: Red LED, one per channel, flashes when the amplifier
output channel has stopped operating.
