Rear Panel overview
Rear panel description
The rear panel of the CAP series slightly varies depending of the output configuration and
power rating, but basically the panel layout for all CAP amplifiers is similar. An XLR input
connector with XLR link-through output connector, a high pass filter switch, a gain control
potentiometer and an terminal block output connector are provided for every channel.
AC Power inlet with fuse
The mains power supply (100~240V AC / 50~60Hz) has to be applied to this AC power
inlet. The connection is made by an IEC power connector and is fitted with a fuse. When
replacing the fuse, make sure that the value of the replacement fuse matches the value of
the original fuse. (CAP224: T4AH/250V - CAP248: T6.3AH/250V - CAP424: T6.3AH/250V
- CAP448: T12AH/250V)
High pass filter switch
By means of this switch, the integrated High Pass Filter (HPF) can be switched ON and
OFF. When the filter is switched ON, frequencies below 400Hz will be suppressed.
This can be useful for eliminating low-frequency hum and noise caused by external
equipment and protects speakers from damage caused by excessive low frequency
transients.
Gain control potentiometer
Each channel is fitted with a gain control knob whereby the level for each individual
channel can be adjusted.
Loudspeaker connections
The loudspeaker output connections are performed using 4-pin terminal block
connectors, making it possible to connect high impedance (100V) loudspeakers to the
amplifier outputs.
Input connections
The input connections of the amplifier are performed using balanced XLR connectors.
Every channel has a XLR input connector and a XLR link output connector. The input
signal from the signal source, pre-amplifier or mixer should be connected to the XLR
input connections. And by means of the XLR link output connectors, the signal can be
linked through to multiple amplifiers.
