INSTALLATION NOTES
At all times, the amplifier has to be operated under appropriate conditions. This includes that the
operation location provideS sufficient ventilation and the device is not exposed to direct sunlight or direct
radiation or reflection from any heat source. Installing the loudspeaker systems choose a location
that is not affected by extreme and / or constant vibration or other mechanical oscillation. Also make
sure that the speakers are installed at locations that are free from dust and / or moisture.
CAUTION
Do not take the risk of electro-shock or shock hazard. To reduce the risk of electro-shock, all connections
have to be accomplished before it is permissible to connect the amplifier to the main supply, Before connecting
the appliance to the mains supply, once again make certain that all connections are carried out correctly and
that no short-circuits exist. The overall sound reinforcement installation has to be in accordance to the
laws, regulations, standards, and guidelines that are relevant and applicable in the country where the
equipment is going to be operated.
AC POWER SUPPLY CAUTION
Before using the amplifier for the first time, make sure that the appliance's voltage is in accordance to
your mains supply. Connect the amplifier only to grounded mains outlets. Connecting the amplifler to
the mains supply(115/230Vac) has to be accomplished by inserting the supplied mains cord into the
corresponding socket and afterward plugging it into a mains outlet.

This interface allows to play MP3/WMA files from USB port or SD card slot. Changing the source only requires
pushing one button. The information is shown in the LCD display, allowing navigation through folders and files. It
incorporates volume control and REPEAT function.
The interface includes a recorder function, allowing to save the mixing information or messages into SD card
or USB driver.
NOTE: It is only possible to play or record using one USB or SD device at a time. Therefore it is
not possible to play a file from the USB port and to record the mix on the SD card. Therefore,
first select the operation (PLAY or REC) and after select the media (SD or USB) to record to.
NOTE: The maximum SD card or USB memory capacity is 32 GB.
OPERATION
- When you insert the USB or SD device, the interface reads the folders and tracks, showing the total number of
each one. for example, “F02, 006" means 2 folders and 6 tracks in total.
- The folders are named with incrementing numbers according to the alphabetic order of the folders inserted in
the device. The folder created when tracks are recorded is named as “FRE”
To navigate between folders and files.
NOTE: During PLAY mode, push these buttons in order to change to the next or previous
folder (depending on the button pushed).

1. Press “REC” button. “REC” will be showed on the LCD.
2. Press “REC” button again. “REC” will flash for 3 seconds. The LCD will then display a counter
showing the incrementing record time in seconds.
The unit incorporates a 1 second delay in order to take time before recording.
3. When you want to finish the recording, press the
button.
4. The track displayed will be stored in the “FRE” folder (This is shown as the “RECORD” folder
when reading the device through a PC).

CONNECTIONS
Mains Connection (25)
The supply transformer has been designed for use on either 115V AC or 230 V AC, selected by this slide
switch on the rear panel (17). The amplifier is factory set at 230 V AC mains voltage.
Input Connection
Inputs 2~5 incorporate balanced standard COMBO sockets (1/4” stereo jack, and XLR 3P) on the rear panel.
Wiring is as follows:

NOTE: Inputs 2~5 incorporate an input selector (11), according to the input surce type (MIC or
LINE). On the other hand, they incorporate a 24V phantom power position for condenser
microphones.
Potentiometers
Turn the front panel potentiometers (1) clockwise to increase the volume or anticlockwise to reduce the volume.
Priority State
Input 5 has the highest priority (apart fromTEL.EMER), overrulling the rest of inputs. This priority will act when
the device detect an input level over the fixed threshold.
- Priority terminals (40) have the same purpose.
PCA 240 USB provides an auxiliary input (INPUT 1) which may be used for connecting other signal sources
such as a Radio Tuner, CD or Cassette player (LINE level). Select the type of the input from the rear switch
(23), and connect the audio source in the rear connectors (20).
Turn the front potentiometer clockwise to increase the volume or anticlockwise to reduce the volume.
The INPUT 1 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.

Chime On/Off
Switching on the manual chime on/off (10) switch on the rear panel and the priority conditions,
chime function will be activated ( “Ding-Dong” pre-announcement chime) when the priority override is activated.
The default volume of the chime is pre-set at the factory and should be suitable for most applications.
Power In & Pre Out (21-22)
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 Connection
This device provides two different types of loudspeaker outputs :
High impedance lines (25/70/100V) and low impedance (4, 8, 16Ω), 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.
Loudspeaker Direct Outputs
PCA 240 USB provides direct outputs according to the designed use:
- High impedance lines (25/70/100V)
- Low impedance (4, 8, 16Ω)
These outputs, give an output at all times, reproducing any input signal into the amplifier (INPUTs 1-5,
USB/SD interface). The chime and priority functions affect these outputs.

The selected zone button will light. You can select any number of zones. Depress the push button to unselect the
zone; the button will go off.
NOTE: Avoid switching on the amplifier without any load connected or without selecting any zone with the front
panel ZONE SELECT buttons.
NOTE: When using any 100 V line zone connections, low impedance speakers should not be used.
NOTE: The total power load connected to all zones MUST not exceed the nominal amplifier power.
Output terminals for auxiliary loudspeaker (14)
These terminals allow the connection of a small external loudspeaker that gets driven by an internal auxiliary
power amplifier, providing a 1 W nominal output. Only the mixed audio signal coming from "INPUT 1" is
included in the output. In addition, the output signal is controlled only by the Monitor volume control (23).
1W 8 ohm
Telephone/Emergency (16)
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 (24).
The terminals allow connection of a telephone/paging system interface.
NOTE: The telephone/Emergency input has the highest priority; all other units will be overriden.
