Installation

CAUTION: Before you begin, make sure that the amplifier is disconnected from 
the power source and all level controls are turned completely down (counter-
clockwise).

1.  If you need to mount the transformer module to rack, use a standard 19-inch 

(48.3-cm) equipment rack (EIA RS-310B) . You can have the following options 

according to your application:
•  Rack mounting the transformer module with a CSA-2120 amplifier
•  Rack mounting single unit 
•  Wall mounting

2.  Connect the input of the transformer module to the output of the CSA-2120 

amplifier with the shipped 4-pin cable. 

3.  Determine the proper transformer module tap to use, based on the desired 

constant-voltage of your system.
