QSC's new 4-channel Digital Cinema Amplifier models (pictured right) and the two-channel DCA3422 have received THX approval from Lucasfilm, which has now passed the entire DCA line for use in THX-certified cinema auditoriums. The seven-model DCA line includes five two-channel models ranging in power from 600 to 1,700 watts per channel (2 ohms). Two 4-channel models, the DCA1824 (450 watts per channel, 2 ohms) and 1644 (400 watts per channel, 4 ohms), are ideal for tri-amped loudspeaker systems, since a pair of channels can be bridged to feed a three-way speaker configuration. All DCA amplifiers feature PowerWave switching power supply technology for added dymanic range, and are equipped with an HD-15 DataPort for interface with QSC's Digital Cinema Monitor (DCM) Series products.
