Introduction
This user manual provides data about the Christie Vive Audio CDA5/CDA7.5 Professional Power
Amplifiers controls, installation, and specifications.
Overview
Christie Vive Audio CDA5/CDA7.5 Professional Power Amplifiers utilize an advanced design that reduces
the weight of the amplifier significantly while increasing output power, reliability, and thermal
efficiency.
Christie Vive Audio CDA5/CDA7.5 Professional Power Amplifiers are designed with a resonant switch-
mode power supply and a high-speed class D topology that yields superior audio resolution and
efficiency. Advanced technology and extensive protection circuitry allow operation with greater
efficiency into difficult loads and power conditions. The ACL (Automatic Clip Limiting) circuitry
provides trouble-free operation into loads as low as 2 ohms. ACL protects loudspeaker drivers and
ensures that sonic integrity is maintained, even in extreme overload conditions. The CDA’s high-
efficiency design allows the amplifier to operate at very low temperatures, and does not require
massive heat sinks for cooling.
