CX-A200 INSTALLATION AND OPERATION MANUAL 1 2 Safety Notes The CX-A200 contains several PCB mounted jumpers which can be set to provide the desired configuration for a specific venue or installation. These adjustments should be performed by a technically qualified person who understands the hazards associated with mains operated equipment. Do not remove the top panel unless you are qualified to do so.
CX-A200 INSTALLATION AND OPERATION MANUAL 4 3 Input Facilities All four inputs are balanced and use 3 pin XLR type connectors. All inputs are wired to the standard convention of pin 1 ground, pin 2 in-phase, pin 3 reverse phase, with the shell of the connector connected to the chassis.

CX-A200 INSTALLATION AND OPERATION MANUAL 5 5 Output Details Binding posts are provided on the rear panel for the four speaker outputs and these can accommodate flexible leads up to 2.50mm². The output connector is not compatible with 4mm 'Banana' plugs. Do not make any connections to the unit with the power cable attached. It is good practice to distance the output wiring from the input wiring.
CX-A200 INSTALLATION AND OPERATION MANUAL 6 circuitry uses the industry standard 'Thats 2150A' VCA providing very low distortion and up to 90dB attenuation. The VCA module can be wired to provide muting by using an auxiliary relay connected to a fire alarm control panel. See section 11 'Remote Level Plate Connections' for wiring details. 10 Fitting a VCA Module Remove the power cable before commencing.
CX-A200 INSTALLATION AND OPERATION MANUAL 12 7 Field Servicing The CX-A200 is ruggedly built and uses proven reliable circuitry. It requires no more than the occasional removal of any dust that may have built up inside the unit as a result of the forced cooling. In the unlikely event of failure, the power amplifier module (4 channels) complete with power supply components and input circuitry can be replaced without special tools and is available as a tested replacement assembly complete with heatsink.
