Stewart Audio – CVA40-1-CV-D

The CVA40-1-CV-D is a single channel PoE++ (60W port power or injector) Dante™ amplifier in a plenum-rated, compact, flange mount enclosure. The CVA40-1-CV-D is a single channel PoE++ (60W port power or injector) Dante™ amplifier in a plenum-rated, compact, flange mount enclosure.
  • One Dante™ input channel
  • Single category cable solution for both signal and power
  • Plenum rated package
  • AES67 support
The PoE++ Amplifier Series leverages the higher power 802.3bt PoE++ standard (60W port power) to power two amplifier models, the AV20-2-LZ-D (20W x 2 @ 4/8Ω) and the CVA40-1-CV-D (40W x 1 @ 70V/100V). These compact Dante™ amplifiers are designed to be single cable solutions for small/medium zones without the need for a local power outlet. This amplifier series leverages the ubiquitous nature of existing CAT 5e/6 cable in zones and also the inexpensive process of pulling new cable to zones. It creates an opportunity to reduce labor costs with a single, reliable, twisted pair cable that carries power and data to where you need it. Simply plug the PoE++ CAT 5e/6 cable into the amplifier, wire the speakers and route audio and repeat for the next zone. The plenum rating and compact size, allows this amplifier series to be placed in the air handling space, closets, the rack or any other convenient space. The confluence of readily available and inexpensive CAT 5e/6 cabling, Dante™ networked audio and quick installation, makes this amplifier series an essential problem solver.
