CXA AMPLIFIER FRONT PANEL DESCRIPTION
Figure 1.1
1. Fan Vent
The CXA-8 & CXA-10 amplifiers are cooled by two rear-mounted
fans. Cool air flows through the front fan filters, reducing the
temperature of internal components while forcing the heat out
the rear vents. Never block these vents and keep them clean at
all times.
2. AC Power Switch
This switch powers the unit on and off.
3. Signal Indicators
These blue LED's will illuminate to indicate that a signal is
present at the amplifier input, and that the signal is being am-
plified.
4. Clip Indicators
These red LED's will illuminate at the clipping threshold. These
lights should not light up during normal use as they indicate
signal outside of the amplification range of the amplifier. When
a signal is "clipped" and the clip indicator illuminates, it means
that the signal is being distorted at the output stage. Prolonged
clipping can not only damage your amplifier, but also your
speakers, so be careful to monitor the clip indicator during setup
and use. If the clip indicator is illuminated then simply lower the
channel gain or input signal until the indicator does not light.
5. Active Indicators
These blue LED's indicate that AC power is connected and the
amplifier is turned on.
6. Protect Indicators
These red LED's indicate that the channel is in Protect mode.
When the channel goes into protect mode all output for that
channel will be muted. The protect LED's light when overheating
or other severe problems occur. This is to protect any speakers
connected to the channel. The LED's also light for approximately
five seconds whenever the unit is powered on and fade slowly
when the amplifier is powered off.
7. Channel input level control
These two 21-position detented potentiometers adjust input
level for their respective amplifier channels. In Bridged Mono
Mode, only channel 1 level control is used to adjust signal level.
In Parallel Mode, both input level control are used to adjust sig-
nal level for their respective amplifier channels. At their fully
counter-clockwise position, the signal is attenuated by more
than 80dB. At their fully clockwise position, the signal is at max-
imum gain.When 0 dBu of signal arrives at the input jacks and
the Channel input level controls are set to their fully clockwise
position, the unit delivers full power output.
