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.

Rear panel overview

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.
