QSC CX168 8-Channel Commercial Power Amplifier

CX168

Designed for permanently installed sound systems where rackspace is at a premium, QSC’s CX108V and CX168 provide unprecedented levels of channel density for multichannel amplifiers. The CX108V and CX168 provide 100 watts per channel at 70 volts and 90 watts per channel at 8 ohms respectively. With both models, 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.
