EN 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.
EN USB/SD INTERFACE DIGITAL AUDIO PLAYER /RECORDER VOL SD MMC REC VOL RPT SD USB 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.
EN CONNECTIONS Mains Connection (33) The supply transformer has been designed for use on either 115V AC or 230 V AC, selected by slide switch on the rear panel (32). The amplifier is factory set at 230 V AC mains voltage. Battery Connection (24V DC) (15) When using externaI batteries, the amplifier must be earthed via the screw terminal due to the high voltages present. This is necessary to ensure the case is earthed and ensure electrical stability.
EN Aux Connection The PCA 120 USB provides an auxiliary input (19) & (20) 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 (CD or AUX) from the front panel switch (6), and connect the audio source in the adequeate rear connectors (19) or (20). Turn the front potentiometer (5) clockwise to increase the volume or anticlockwise to reduce the volume.
EN Example loudspeaker output connections (15) & (16) 8A 8A + 0 100V 0 100V 0 100V 8 ohm Connecting a single speaker to 8 ohm output Connecting multiple speakers in parallel to the 100V PRORITY ONLY output Output terminals for auxiliary loudspeaker (39) 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 "AUX IN" is included in the output.
