CVA-1100 is a 100W constant power amplifier board consisting of a power unit and an amplifier unit, designed for distributed speaker systems like background music system, alarm system, broadcast system and so on. It can continuously output 70V/100V RMS directly with no need of an output transformer, which means you can connect the output directly to the distributed speakers with transformers. Besides the default constant voltage mode, CVA-1100 can function as a constant resistance amplifier board, driving an 8Ohm speaker for local audio playback. CVA-1100 features high reliability and stability, guaranteed by equipped full protection circuit, perfectly applicable to high demanding commercial and industrial applications.

Features:

Transformer-less 70V/100V RMS Output

Supporting Both Constant Voltage and Constant Resistance Mode

Wide Power Supply Range as 90VAC-254VAC

Two Levels Gain Adjustable

STRONG ENOUGH, To survive in the most harsh environments.

SMALL ENOUGH, To make each space most effective.

SURE Electronics will be transformed into a professional designer and a manufacturer of Class-D audio amplifiers and matched power supplies. So SURE brand will fade away from retail and Sure Electronics will be committed to provide solutions, instead of direct products, for our distributors and partners. Our company name, Sure Electronics, will always remain the same.
