VA series

The VA series two-channel ring variable power amplifier adopts the SAE patented technology Class I™+ ring variable power supply technology topology, achieving high efficiency, low distortion, and pure sound quality performance. After dozens of rounds of layout optimization and circuit adjustment, as well as technical details demonstration of “electromagnetic compatibility analysis” and “signal integrity verification”, the product manufacturability and pass rate have been greatly improved.
With a super-wide power range from 400W to 1500W, it flexibly adapts to different-sized application venues, easily handling everything from conference rooms and multi-function halls to theaters and live houses.

Features

  • Powered by a high-quality toroidal transformer.
  • High-efficiency Class I™ power amplifier module.
  • High-sensitivity CMRR balanced input enhances noise suppression
  • With S/N rate(A) ≥110dB, it boasts high resolution and dynamic performance.
  • XLR input/link socket; two red and black poles and SpeakON Nl4 output socket.
  • The front panel features independent channels for power supply, protection, peak clipping warning, and signal indicator lights.
  • The rear panel features an input sensitivity selection.
  • The back panel offers three connection modes for setting (stereo/bridge/parallel).

application

  • Fixed installations requiring long-term operation, such as theaters, churches, and stadiums.
  • Lightweight body and high cost-effectiveness, suitable for rental and small to medium-sized outdoor mobile performance applications.
  • High-end entertainment sound reinforcement applications with high sound quality requirements and moderate prices, such as premium KTV, Livehouse, bars, and multi-function halls.
