3.2.1 Indicators
The CVA100-2 has a set of indicators for power, signal, and clip located
on both the front and the rear of the amplifier. The redundant indicators
are intended to ease installation by giving feedback regardless of being
in front of or behind the unit.
The “Power” and “Active” LEDs indicate whether the amplifier is be-
ing supplied proper AC power and is active (not in sleep mode) respec-
tively. The amplifier will go into sleep mode after approximately thirty
minutes of no signal on either input. When it does so, the “Active”
light will go out leaving just the “Power” light on. As soon as signal is
detected again the “Active” LED will illuminate indicating that the am-
plifier is now back in normal operation mode.
The green LEDs, labeled “Sig”, will light when an audio signal is pre-
sent on the corresponding audio input channel. The red LEDs, labeled
“Clip” will illuminate when the signal is too hot. The “Level” control
for that channel must be adjusted until the “Clip” LED goes out for un-
distorted sound amplification. If clipping still occurs when the “Level”
control is turned all the way down (counter-clockwise), reduce the sig-
nal at the source.
3.2.2 Controls
All CVA100-2 controls are located on the rear of the unit. There is no
power switch so the amplifier will power up into a sleep state when
power is first applied. The CVA 100-2’s Signal Sense Technology
(SST™) will power up the amplifier from sleep when a signal is detect-
ed. After 30 minutes without an input signal the amplifier will go into
sleep mode.
To adjust the input sensitivity knob, you will need a small flat-head
screwdriver. While a typical program source level is present, spin the
rotary knob as far clockwise as you can without hearing distortion or
without the “Clip” indicator glowing red. If the signal is distorting and
the knob is all the way counter-clockwise, adjust the gain down at the
source level.
