DESCRIPTION
The OMNITRONIC PA 240 is designed for professional application. The inputs and outputs are located on the
rear panel, the gain controls on the front panel.
The OMNITRONIC PA 240 is sustained short-circuit proof, protected against overtemperature and features
turn-on delay and load-independent clipping LEDs.
The OMNITRONIC PA 240 is equipped with 6.35mm and Cinch input jacks and Screw/clamp output jacks.
RACK MOUNTING
The amplifier is built for 19" racks/483mm. The height is 108mm only. You can fix the amplifier with four
screws M6 in the rack.
When mounting the amplifier into a rack, please make sure that there is a proper air circulation. Steady over-
heating will damage your device.
The amplifier’s total power consumption consists of the output power passed on to the speakers and the po-
wer loss which has to be passed on to the air in the form of heat.
Please make sure that there is enough space around the device so that the heated air can be passed on. The
rack should be provided with a cooling fan.
Your amplifier additionally features built-in cooling fans that supply the necessary ventilation. Since the heated
air is passed on through the device’s rear panel, the back of the rack should be left open during operation.
Be careful when mounting the amplifier into the rack. Put the heaviest devices into the lower part of the rack.
Be aware that fastening the amplifier with four screws on the front panel is not enough. In order to ensure
safety, additional fastening by using ground and side bars is necessary.
If racks are to be transported or used for mobile use, additionally fasten the devices by connecting the rear
brackets with the side or ground bars of the rack. In this way, the amplifier cannot be pushed backwards. The
front panel alone is not designed to absorb acceleration forces occuring during transportation.
