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
