VO+ series

The new VO+ series is specially designed for vocal singing. It has high resolution and high dynamic performance. It is thicker and warmer, easy to sing without effort, and can give super dynamic, not easy to produce cracking sound, suitable for the current mainstream KARAOKE style. The new VO+ series is easy to operate, stable in work, cost-effective, and widely used. In addition to karaoke, it is also suitable for speech reinforcement, small and medium-sized performances, conferences, music restaurants, multi-functional halls and other occasions.


  • High quality toroidal transformer power supply.
  • Class H power module (VO24+/VO36+).
  • High-efficiency Class I™ power module (VO48+/VO52+).
  • XLR input socket and SpeakON NL4 output socket.
  • Three connection modes can be set (stereo/bridge/parallel).
  • The rear panel has input sensitivity selection (0.775V/1.0V/32dB).
  • There is a power circuit breaker on the rear panel.
  • The front panel has independent channel, peak clip warning, signal indicator, protection and power indicator.


  • Party K best choice.
  • Application of public broadcasting, multi-functional theater, cinema and other multimedia engineering sound reinforcement.
