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

We have recently released a new member of KAB series – KAB6-415, a 4CH audio amplifier board specially designed for game machine applications. It is developed based on TI TPA3110 amp IC, delivering 15W output power per channel into an 8Ohm load. It features compact size, full protection and high reliability, applying to audio 4.0 system. Thanks to easy installation, KAB6-415 can be integrated into most projects simply. Industrial pluggable terminal blocks make it easy to be integrated in systems. KAB6-415 supports being configured as 2.1 mode or 2.0 mode, greatly improving the flexibility of the whole audio system.
