CST-2120 Overview
The rack-mountable JBL Commercial
impedance and voltage matching from the CSA-2120 amplifier to drive 70V and
100V distributed speakers systems.
This unit allows amplifiers without direct 70V or 100V output capability to drive
distributed speaker systems designed to operate at those voltages.
Features
• Provides two channels of impedance matching for "Constant-Voltage" operation
• Provides 70V and 100V output when used with CSA-2120 amplifiers
• Allows the CSA-2120 to be easily integrated into distributed systems
• Detachable Euroblock input and output connectors are included.
