Description
The sub compact CVA-25-1 and CVA-50-1 are built to meet the rigorous demands of high quality commercial, industrial and Pro Audio sound installations. Low cost, lightweight and convection cooling make this Class D amplifier flexible enough for a broad range of applications requiring quiet amplification. With an extremely compact form factor, the CVA's allow amplification to be located in places normally off limits to standard amplifiers without compromising sound or power.
Features- Sub Compact 1/4 rack package
- Mono constant voltage amplifier (25V or 70V)
- Music and fire alarm muting
- Clean full"–range dynamic power
- Signal Detect trigger for sleep & wake up
- Remote volume control
- Multiple mounting options
- External inline power supply
The Plenum rating (UL 2043) and remote volume control further compliment the recessing options. Our Signal Sense Power Technology TM (SSPT TM) ensures the amplifier is only powered when there is a signal present, saving energy and extending product life. Like all Stewart products, the CVA's are designed for sonic accuracy, high efficiency and extended duty cycles.
