JBL Commercial CST-2120 CST Transformer Kit for CS Commercial Solution Series Public Address System

The rack-mountable JBL Commercial CST-2120 transformer module provides impedance and voltage matching from the CSA-2120 amplifier (with 4 and 8 ohms outputs) to drive 70 V and 100 V distributed speakers systems. This unit allows the CSA-2120 amplifier without direct 70 V or 100 V output capability to drive distributed speaker systems designed to operate at those voltages.
