Appendix A: Optional Item - Transformer Module

The rack-mountable JBL Commercial

CST-2120 transformer module provides impedance

and voltage matching from the CSA-2120 ampliﬁer (with 4 Ohms or 8 Ohms outputs) to

drive 70V and 100V distributed speakers systems.

This unit allows ampliﬁers without direct 70V or 100V output capability to drive distributed

speaker systems designed to operate at those voltages.

Features

• Providing two channels of impedance matching for “Constant-Voltage” operation

• Providing 70V and 100V output when used with CSA-2120 ampliﬁers

• Allowing ampliﬁers without direct Constant-Voltage capability to be easily integrated

into distributed systems

• Detachable Euroblock input and output connector
