1 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.
Remove the power cable from the unit before removing the top panel and do not make any adjustments with the unit switched on.
The CX-A200 is supplied with a power cable fitted with a moulded plug. If the plug is cut off the lead for any reason, remember that the discarded plug is a potential hazard and should be disposed of in a responsible manner.
2 General
The CX-A200 is a four channel power amplifier with a maximum output of 50 watts per channel into 4 ohm loads. The unit features extremely low distortion and low noise together with a high slew rate. Full circuit protection is provided and the load is disconnected if the heatsink overheats or any DC is detected at the output. A five second switch-on delay operates to avoid any switching thumps or other extraneous signals reaching the speaker system.
All four input amplifiers are balanced and connect via 3 pin XLR type connectors with adjacent level controls, all mounted on the rear panel. Input signal routing jumpers are provided and allow the unit to operate in many configurations whilst retaining simple input connections.
The CX-A200 amplifier can be used with up to two optional plug-in two channel VCA modules to provide remote level control. Each plug-in module can operate as two individual attenuators with two remote level controls, or can be linked to operate as a stereo pair with one remote level control.
3 Installation
The CX-A200 is suitable for mounting in a standard 19" equipment rack and occupies two units of rack space. Sufficient ventilation must be provided for the unit. The amplifier draws cool air through the front panel and exhausts through the back panel and care must be taken not to obstruct the air flow otherwise the unit may intermittently turn off due to the built-in thermal protection. The unit is 300mm deep but a depth of 375mm should be allowed to clear the connectors.
