AUDAC CEP Series User manual

CEP series
Multi-zone Amplier
The quick start guide gives you an overview of all the front and rear panel controls and connections on the
CEP series ampliers. The CEP series include the CEP408 (4 x 80 Watt) and the CEP 803 (8 x 30 Watt).
It allows you to get started with the installation of it in your project.
To get a detailed explanation of all functions, please check the complete manual which is available on the
web page https://manuals.audac.eu/CEP408 or scan the QR code as shown on top of this page.
Front:
2) Power switch with LED:
Allows to power the system ON and OFF. The indicator LED
illuminates in blue when switched ON. When switched to
standby (energy-saving) mode, the power LED will illuminate
in orange colour. The amplier switches automatically to
standby mode when no signal is available for 30 minutes.
2) Rackspace enclosure
The CEP series is equipped with mounting options for a 19”
1HE rackspace.
1) Indicator LED (VU):
The (VU) indicator leds indicate the output level and status
of the amplier (Signal / -10dB / Clip / Protect).
1) AC Power inlet:
The mains power supply (100-240V AC - 50/60 Hz) has
to be applied to this AC power inlet. The connection is
made by an IEC C14 power connector.

3) Speaker output
A) Loudspeaker output connections:
The loudspeaker output connections are performed using
4-pin terminal block connectors, making it possible to connect
high and low impedance loudspeakers to the amplier
outputs. Selection can be made between low impedance
(4Ω) or constant voltage (100V / 70V) depending on project
requirements. More information about loudspeaker output
connections is described in the ‘connecting the system’
chapter.
A) Input connections:
Balanced mono sources can be connected to the
3.81mm Terminal block input. A gain control potentiometer
adjusts the sensitivity within a range of 0 dB ~ 50 dB which
allows connection for both microphone or line-level audio
sources.
B) Auto standby switch:
The amplier has an automatic standby function. The amplier
switches automatically to standby mode when no input signal
is available for 30 minutes. If desired, the automatic standby
mode can be disabled via this switch. The standby function
is by default activated.
B) Linking switch :
Different input channels can be linked together. Pushing the
button between two channels will link them to each other. This
function eliminates the need to connect inputs with cables.
By pushing the buttons sequentially, multiple channels can
be linked together.

Connecting the system:
ATTENTION:
Make sure the power of the device is turned OFF before
any connections or wiring adjustments are made.
Disregarding this rule can lead to permanent damage of
the equipment.
For operating using constant voltage (100V / 70V) audio
distribution systems, all speakers shall be connected in
parallel on the corresponding output terminals, non exceeding
the maximum wattage / minimum impedance of the amplier
The loudspeakers should be connected to the 4-pin terminal
block connectors on the rear panel of the amplier. Selection
can be made between low impedance (4Ω) or constant
voltage (100V / 70V) depending on project requirements.
The corresponding terminals and settings shall be chosen
depending of the loudspeakers and installation type.
The table below shows the output voltage, impedance and
maximum power load per channel for each amplier model.
For operation in low impedance (4 ohm) mode, any
loudspeaker (or combination) with an impedance higher or
equal to 4Ω can be connected.
CEP408 4 Ω 62,5Ω/70V 125Ω/100V
167Ω/70V 333Ω/100V
80W
CEP803 4 Ω 30W
Depending on the chosen connection method (low
impedance or constant voltage), the output conguration
setup shall be congured accordingly.
Do not connect high and low impedance speakers to one
output at the same time.
