The CSA2120 2-Channel Installed Sound Power Amplifier from JBL features 120 watts of output per channel at 4 or 8 ohms and is designed for installed sound applications. Each of its two input channels has dual summing RCA inputs and a 3-pin detachable Euroblock input. Both channels also feature a selectable limiter and high-pass filter at 70Hz. The CSA2120 has a 4-pin Euroblock output connector for powering dual loudspeakers. The auto-standby mode disables the amplifier pulse width modulation generator when there is no signal detected. 

The CSA2120 has both over-heat and low-voltage protection and can be rackmounted with the included rackmount kit. It has front-panel channel volume controls as well as clip, signal, and power LED indicators. The unit is powered by a switch-mode universal power supply.
