Designed for permanently installed sound systems where rackspace is at a premium, QSC's CX108V provides unprecedented levels of channel density for multichannel amplifiers. The CX108V provides 100 watts per channel at 70 volts and 90 watts per channel at 8 ohms respectively. Each pair of channels may be bridged to configure these amplifiers as 4, 5, 6 or 7 channel units. Like the entire CX Series, the 8 channel models feature DataPorts for remote amplifier management or signal processing, incorporate QSC's legendary PowerLight™ technology, and deliver our unmatched reputation for quality and reliability.

QSC CX108V Features

  • 100 watts per channel at 70 volts (CX108V)
  • 90 watts per channel at 8 ohms and 130 watts per channel at 4 ohms (CX168)
  • Compact size - only two rack spaces and 14" deep for reduced rack space
  • Channel pairs bridgeable for maximum flexibility
  • Exclusive PowerLight switch-mode power supply technology for high performance and compact size
  • Active Inrush Limiting eliminates AC inrush current, removing the need for expensive power sequencers
