CXL-3120 Installation Instructions v1.0 2
INTRODUCTION
The CXL-3120 is an optional transformer module for the 36-50 Multi-Zone Mixing Amplifier. It permits the 36-50 to directly drive
100 V or 70 V-line loudspeaker systems. The module itself consists of three transformers (one each for Zone 1, Zone 2 and the
Utility Output) mounted on a PCB, and is supplied in kit form with all the necessary fixings and wiring. Any or all of the 36-50’s
outputs may be converted to 70/100 V-line operation as wished. Each transformer is rated at 40 W.
The CXL-3120 transformers are not of the “auto transformer” type, and hence provide a fully balanced output signal which is
isolated from the amplifier.
The module is easily mounted within the 36-50’s enclosure, using pre-drilled fixing holes. The outputs are then available on a 6-pin
5 mm-pitch screw-terminal connector which occupies the hole (shown below) in the rear panel normally covered by a blanking
plate.
