About the JBL CST-2120

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.

JBL CST-2120 Features

  • Providing two channels for constant voltage operation
  • 70V/100V Outputs
  • Rack-mountable with CSA2120
  • Detachable block input and output connectors
