access menu items and front panel lockout.
LCD Screen: Backlit liquid crystal display shows speaker presets and signal
processing.
Signal Indicator: Green LED, one per channel, illuminates when a very low-level
signal is present at input.
?10 Indicator: Green LED fl ashes when output signal exceeds ?10 dB below
clip.
?20 Indicator: Green LED fl ashes when output signal level exceeds ?20 dB
below clip.
Ready Indicator: Green LED, one per channel, illuminates when the amplifi er is
ready to produce audio.
Clip Indicator: Red LED, one per channel, turns on at the threshold of audible
distortion.
Temp Indicator: Red LED, one per channel, illuminates under excessive temperature
conditions.
Power Indicator: Blue LED illuminates when the amplifi er has been turned on
and has power.
Rear panel controls and connectors shall include the following:
AC Line Connector: NEMA 5-15P (15A).
Input Connector: Two 3-pin removable Phoenix-type connectors each accept a
balanced line-level input signal.
