Features · Digital Input for up to 16-Channels of audio · Networked audio I/O via CobraNetTM · Network control and monitoring via SNMP · Serial automation control via RS-232 · Analog Inputs for film processors, non-sync and Mic/line · Master volume and full 1/3 Octave Graphic EQ on all channels (except subwoofer) · Booth Monitor with touch screen control for easy operation · Digital Loudspeaker Crossovers · Three or five screen channels -- Passive and 2, 3 or 4-way crossovers · Compatible with all existing DCA amplifiers -- thousands of DCA equipped screens are ready for full network monitoring and control · Dual power supplies with load sharing for seamless operation in the event of failure · SD Memory card for quick unit swap -- restores all settings · Multiple Bypass modes routes audio around failed components to insure that the show will go on · DSP presets for DCS speakers for great "out of box" performance and reduced set-up time · QSControl and QSCreator allow for the creation of custom control screens and remote access for fault reporting and diagnosis · Easily integrates with existing film processors for dual film/ digital projection systems · CobraNet offers digital non-sync routing and future expansion capability · Continued development of software and firmware will add new capabilities to the existing hardware with easy firmware updates · The EX 4000 is part of a new generation of QSC products designed expressly for the needs of D-Cinema sound systems Digital Signal Processing The EX 4000 digital signal processing capability outperforms traditional analog crossovers and equalizers for optimized speaker performance. [. . . ] Crossover frequency, 1/3 octave graphic EQ, parametric equalization, polarity, delay and gain can be precisely adjusted for each speaker in your system. Active 2-way, 3-way and 4-way crossovers are available. Advanced crossover presets for QSC DCS speakers speeds system set-up and insures maximum performance. Less Wiring, Faster Set-up DCPs greatly simplify system wiring and set-up, significantly reducing installation time and labor cost. Input to the DCP is provided via standard DB-25 cables from the D-Cinema server and/or 35 mm cinema processor. Connections to DCA amplifiers for input and monitor signals are made through a single QSC DataPort/VGA-style cable. The NAC 100 Ethernet remote control panel provides remote operation in a multiplex from anywhere on the local network.
