External Connection
Always use proper ready-made insulated mains
cabling (power cord). Failure to do so could result
in shock or fire. If in doubt, seek advice from a
registered electrician.
Do not Remove Any Cover

Mains Connection (15)
The supply transformer has been designed for use on either 115V AC or 230 V AC, selected by a slide
switch on the bottom of the device. The amplifier is factory set at 230 V AC mains voltage.
Input Connection
Inputs 1-4 feature both balanced standard COMBI socket (1/4” stereo jack, and XLR 3P) and terminal blocks
on the rear panel.
Wiring is as follows:

Selected Functions by Dip-Switch block
Each input incorporates several functions
configurable through a dip-switch block:
Switch 1: AUDIO SOURCE SELECTION: Setting the switch to the ON position, the input will accept
microphone level audio. Setting it to the OFF position, the input will accept LINE level.
Switch 2: PHASE INVERSION: Setting the switch to the ON position, the signal will be inverted 180º.
Setting it to the OFF position, the signal will be unaffected.
Switch 3: HIGH PASS FILTER: Setting the switch to the ON position, the input will be processed by a
high pass filter with a 200Hz cutoff frequency. Setting it to the OFF position, the
signal will be unaffected.
Switch 4: PHANTOM POWER: Setting the switch to the ON position, + 48V phantom power will be applied
for condenser microphones. Setting it to the OFF position, this function will be disabled.

user manual
The PCA 410 provides two auxiliary inputs (AUX 1-2) which may be used for connecting other signal sources
such as a Radio Tuner, MP3 player, computer, CD or Cassette player (LINE level). Connect the audio source to
the rear connectors (19, 20).Turn their respective potentiometers clockwise to increase the volume or
anticlockwise to reduce the volume.
These input sockets are standard RCA phonos, two sockets are supplied and these are linked together
internally in parallel, this allows stereo signal source to be used without the need to obtain a special lead,
however you may wish to check with the manufacturer of the signal source to ensure that no damage will result if
the left and right output channels are connected together in parallel.

PRIORITY
INPUT 1 has the highest priority (apart fromTEL/EMER), overriding the rest of inputs. To activate the priority state
short-circuit the Priority terminals (21) on the rear panel.
CHIME ON/OFF
To activate the CHIME, both the front panel switch (10) must be depressed, and a short-circuit made between the
CHIME PRIORITY terminals on the rear panel(30). This will activate the chime function (‘Ding Dong’
pre-annoucement chime). Whilst the CHIME state is enabled all inputs will be overridden.
The volume of the CHIME can be set from the CHIME potentiometer on the front panel.
SIREN ON/OFF
SIREN can be activated in one of two ways:
- Pressing the front panel switch (11)
In that case, the SIREN WILL BE ACTIVATED UNTIL THE SWITCH IS PRESSED AGAIN (OUT POSITION).
- Making a short-circuit in the SIREN terminals (29) in the rear panel.
In that case, the SIREN WILL BE ACTIVATED UNTIL THE SHORT-CIRCUIT IS REMOVED.
Whilst the SIREN state is enabled all inputs will be overridden.
The volume of the SIREN can be set from the SIREN potentiometer on the front panel.

Telephone/Emergency (28)
The Telephone/Emergency input is for emergency announcements/signals and is not affected by the Master
volume control. The volume can be set by the tel. paging volume control (27).
The terminals allows connection of a telephone/paging system interface.
NOTE: The Telephone/Emergency input has the highest priority, all other units will be overriden.

Power In & Pre Out (17-18)
These sockets connect the mixer/preamplifier stage to the power amplifier stage. The connecting link must be
plugged in for normal operation as a mixer/amplifier. If a compressor/limiter, equalizer, or other external signal
processor is used in the sound system, connect the “PRE OUT” to the input of the external processor
and the output of the processor to “POWER IN” In the signal chain, “PRE OUT” is after the tone controls
and the master volume control.
Loudspeaker Connections
The PCA 410 includes 4 discrete outputs and each output section provides two different types of loudspeaker
outputs in each one: High impedance lines (25/70/100V) and low impedance (4, 8Ω). You can only use one of
these outputs at any one time; any attempt to use two or more of these may result in damage to the amplifier.
