QSC debuts the DXP digital expansion processor at CinemaCon

News

Las Vegas—QSC Audio Products LLC is introducing its DXP digital expansion processor for the first time at the company’s booth at CinemaCon, the annual convention of the National Association of Theatre Owners, which runs until April 26.

The DXP works with the existing DCP 200 and 300 cinema processors to create an exceptionally powerful networked audio solution for cinema. The DXP is a 1U rack mount DSP processor that connects to the DCPs via CobraNet. CobraNet routes digital audio and control information over Ethernet to allow the DXP to be mounted near the loudspeakers if desired.

The QSC DCA Series amplifiers connect to the DXP via a DataPort interface. The DataPort connection supplies audio to the amplifier and controls the AC power while monitoring key amplifier conditions such as clipping and heat-sink temperature. The audio output of the amplifier is returned to the DCP by the CobraNet connection so that it can be listened to via the DCP's built-in monitor speaker.

When mounted behind the screen with the amplifiers, the DXP eliminates the need for long and expensive speaker cables and conduit. Inexpensive Ethernet cable and a local AC power source can greatly reduce the cost of system wiring. The DXP is also useful in "boothless" cinema concepts, as the entire sound system need not be located in a single, large rack.



The DXP provides 12 DataPort connections and all of the necessary DSP for loudspeaker crossovers. For very large systems, up to two DXPs may be connected to each DCP. The DCP/DXP combination is ideal for multichannel audio systems with up to 16 inputs.


The QSC Cinema Solutions portfolio, featuring the new DXP digital expansion processor, can be seen at CinemaCon tradeshow Booth 613F in the Augustus Ballroom at Caesars Palace in Las Vegas.
