Introduction
Compact dual-channel power amplier
The SCP series is a range of extremely powerful compact dual-channel power ampliers for commercial use.
These half 19” devices can be used in stereo low impedance or 70/100V bridge mode. There are 3 different
models to serve a wide range of applications with power ratings that vary between 240W to 600W in a half 19”
rack space housing.
The compact and elegant design of the half 19” rack space enclosure allows for single installation in a 10.5”
equipment rack, or side-by-side (two devices) in a 19” equipment rack.
A connection to the WP2xx series input wall panels or volume controllers can be made via the RJ45 connectors
on the back of the SCP.
Equipped with a standby mode switch, the SCP series will enter an energy-saving standby mode after a period
of inactivity. This feature together with the overall energy-efcient design makes the SCP meet the high standards
of the Energy Star certication.
When you combine the SCP series with a suitable pre-amplier or wall-mounted input panel you create a powerful
and complete solution for background music installations.

Front panel overview
Indicator LEDs (VU):
Channel monitoring is made convenient by four indicator LEDs for each channel.
The LEDs give a continuous indication of the operation of the corresponding channel. The green signal LED illuminates
whenever a signal is present, while the -20dB LED illuminates when the input signal exceeds the -20 dB 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 should illuminate only (or maximum) at peak levels.
When the Clip LED illuminates, the output limiter of the amplier will intervene avoiding a distorted “Clipping” sound 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 will also illuminate when the external mute contacts
are activated.
Power switch:
A power switch is used to switch the amplier on and off. The LED ring around the switch illuminates in blue colour when the
power is switched on or will illuminate in orange color when switched to standby mode.

AC Power inlet with fuse:
The mains power supply (100-240V AC - 50/60 Hz) has to be applied to this AC power inlet.
Mute connection:
A priority mute contact connection is present which allows complete muting of background music at presence of a contact
closure between both ‘MUTE’ contacts.
This contact is convenient for situations where a separate emergency system is installed and complete background music
muting is required. For example at the occasion of a re alarm. The emergency system output contacts can be linked to
this contact input. When a N.C. contact trigger is being used, a contact bridge shall be used between both N.O. contact
terminals.
Audio output connection:
The speakers shall be connected to the terminal block output connector. Depending on the setup, two speakers can be
connected in low impedance stereo setup, or one speaker line can be connected in constant voltage 70/100V bridge
conguration. Typical wiring applications are shown in the following diagrams.

Remote audio input:
A remote audio wall panel (e.g. WP2xx) can be connected to the bottom ‘Remote audio’ RJ45 connector for providing a
remote audio input. The connection of this extension port can be made by using CAT5e (or better) twisted pair cable in a
straight pinout conguration.
Pinout and colour coding is described in Chapter 1 of this instruction manual. The remote audio input provides stereo balanced
line input with an input sensitivity of +12dBV and a +24V output for powering external audio panels. The audio signal from
the remote audio input is mixed with the ampliers line inputs.
Remote volume control:
The top ‘Vol Ctrl’ RJ45 connector allows for an external control of the main volume of the SCP amplier. The connection of
this extension port can be made by using CAT5e (or better) twisted pair cable in a straight pinout conguration. Pinout and
colour coding is described in Chapter 1 of this instruction manual.
The remote volume controller connection is designed for use with a suitable volume controller (e.g. Audac WP200, VC3208). It
is a VCA input, working between 0-10V (linear envelope), and can be used with an external 0-10V control system. The ampliers
overall volume is controlled dependent on the applied control voltage. A control voltage of 10V means no attenuation, while
0V mutes the amplier. When no external controller is connected, the volume is at maximum.
Standby switch:
The Standby mode of the SCP can be turned on or off. When enabled, the SCP will automatically go into standby
mode after 30 minutes of inactivity (no signal detection).
Stereo- (Lo-Z) / bridge- (Hi-Z) mode switch:
Provides the possibility to switch the amplier between Lo-Z and Hi-Z mode. If this switch is set to Lo-Z stereo, the output
will be stereo can capable of driving low impedance speakers. If it is set to Hi-Z BTL/HPF, both output channels are bridged
and capable of driving high impedance / constant voltage speaker systems. The output voltage can be switched between
70/100V through using corresponding switch, depending on the requirements of the installation. An HPF (70 Hz) will be
enabled when switched to Hi-Z.
70V / 100V switch:
When switched in Hi-Z mode (STEREO - BTL-HPF) the output voltage can be switched between 70/100V using this switch.
Balanced stereo line input:
The balanced stereo line inputs use 3-pins terminal block connectors. All different kinds of balanced and unbalanced line
level audio sources can be connected to the line inputs. Some examples are pre-ampliers, mixers and spoken messages
through an audio source. It is tted with a gain control potentiometer by which the input sensitivity can be controlled within
a range of -3 dBV ~ +7 dBV.
