User manual QSC AUDIO EX 800

[. . . ] The EX 800 offers most of the features of the DCP 300 but at a lower price point for systems that don't require screen channel crossovers but instead utilize CobraNet network audio distribution to additional Basis processors. [. . . ] The EX 800 covers cinema systems ranging from three to five screen channels and up to 16 digital inputs. Outboard Basis processors support passive, bi-amp, tri-amp or quad-amp crossovers and subwoofer outputs. The EX 800 is compatible with all analog cinema processor formats including Dolby® Digital SurroundEX and DTS-ES and features a 10-channel analog input for integration with existing 35 mm audio systems. Features · Digital Input for up to 16-Channels of audio · Networked audio I/O via CobraNetTM -- supports behind-the-screen mounting of Basis processors for screen channel and subwoofer DCA amplifiers · 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 · DataPorts for surround channel amplifiers · 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 · 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 audio routing via Basis processors · Continued development of software and firmware will add new capabilities to the existing hardware with easy firmware updates · The EX 800 is part of a new generation of QSC products designed expressly for the needs of D-Cinema sound systems Digital Signal Processing The EX 800 digital signal processing capability outperforms traditional analog processors for optimized audio performance. Fader level, 1/3 octave graphic EQ, parametric equalization, polarity, delay and gain can be precisely adjusted for each channel in your system. In addition, the DCP detects all amplifier clipping, protect modes and heat sink temperature for reporting via SNMP or a QSControl Ethernet monitoring system. QSControl and QSCreator allow for the creation of custom control screens and remote access for fault reporting and diagnosis. The NAC 100 Ethernet remote control panel provides remote operation in a multiplex from anywhere on the local network.
