An auto-standby mode reportedly allows the amplifier to save energy by disabling the amplifier pulse width modulation generator when there is no input signal. The CSA2120 also features thermal and low-voltage auto protection.

The amplifier includes two optional accessories—a mounting kit and transformer module. The mount kit allows for installation into a cabinet or wall and if a loudspeaker system requires higher impedance, the transformer module can be connected to obtain impedance matching.

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 70V and 100V distributed speakers systems. This unit allows the CSA2120 amplifier without direct 70V or 100V output capability to drive distributed speaker systems designed to operate at those voltages.
