JBL CST2120 Transformer Module

The JBL's CST-2120 is a transformer module designed to provide impedance and voltage matching for the CSA-2120 amplifier, allowing it to drive the 70V and 100V distributed-speaker systems common in most commercial venues. This signal processor is suitable for use in restaurants, theatre lobbies, grocery stores, and other places requiring background music. In other words, this transformer module enables amplifiers that were previously unable to deliver output voltages of 70V or 100V to function with systems that were meant to operate at those levels. It has two channels for this purpose, each with a power output of 120W.

• Provides 2 channels of impedance matching and voltage matching for constant voltage operation
• Provides 70V and 100V output when used with CSA-2120 amplifiers
• Rackmountable; can be easily integrated into distributed systems
• Detachable block-input/output connectors
