Front & rear panel
Front panel description
The front panel of the CAP series slighly varies depending of the output configuration and
power rating, but basically the panel layout for all CAP amplifiers is similar.
Power switch
A power switch allows to switch the amplifier on and off, while the blue indicator LED
located next to the button illuminates when the power is switched on.
Indicator Led’s
Four LED’s for every channel indicate the operation of the amplifier. The green Signal
LED illuminates whenever a signal is present, while the -20dB LED illuminates when the
input signal exceeds the - 20 dBu level. The Clip LED illuminates when the corresponding
channel is working at maximum level. To ensure the best signal-to-noise ratio, the Clip
LED may only illuminate at peak levels.
When the Clip LED illuminates frequently, the amplifier will be overloaded, a distorted
“Clipping” sound will be available on the output. The Protection LED will illuminate when
overheating occurs, or any other fault is detected. When the protection LED is illuminated,
no signal will be available on the outputs. The protection LED’s will also illuminate for a
few seconds when powering up the amplifier, and when the amplifier is switched off they
will slowly fade out.
