It is designed for use in single or two channel modes with bi-amplified and tri-amplified loudspeakers along with subwoofers. The MX8750 has two input channels each with eight outputs that can be configured in any combination of input to output. Its functions include crossover filters, parametric equalization, shelving EQ, HP and LP filters, delay, polarity and limiting. The range and quantity of processing finctions assures being able to achieve optimum system perfor- Input Type Input Impedance Max. Input Level Output Type Output Impedance Max. Output Level Frequency Response Total Harmonic Distortion Dynamic Range Output Noise Two (2): Active balanced 18k Ohms +20dBu Eight (8): Active balanced 112 Ohms +20 dBu ±.25dB, 20Hz-20kHz <.01% @ 1kHz, +20dBu .110dB, 2-20kHz, unweighted <-90dBu, unweighted The MX8750 is controlled by using EAW software and a Windows PC with an RS-232 or midi interface. There is a full comple- ment of level and status indicatores plus individual output mutes for setting-up and troubleshooting systems. FEATURES - Fully controllable configurations and signal processing func- - Digital processing for precise settings - 6 bands of parametrice EQ on each input, 5 on each output and 7 crossover types ensure optimum performance - Each EQ band is selectable between full parametric or first and second order hi/lo shelving filters - Active balanced input and outputs with XLR connectors The concept of Closed Coupled Electronic ProcessingTM (CCEPTM) is central to the EAW design process. EAW engineers integrate elec- tronic signal processing into the total loudspeaker system but we recognize that electronics can only improve performance after all EQ Filters EQ Filter Type Parametric Bell and Shelving (6dB/ oct. & 12dB/oct.)

The MX8750 Output Delay processor is capable of providing complex asymetrical crossovers, Digital Processing delay compensation, parametric equalization, LPF ands HPF filter- A/D converters ing, shelving EQ and limiting. While all parameters are fully ad justable, the MX8750 can be configured using factory-determined D/A Converters Sample rate 48kHz settings for a particular loudspeaker system. DSP Processing 24 Bit, 56 Bit Accumulator, 200 MIPs CONFIGURATIONS Propagation Delay 1.46 msec The MX8750 processor is field configured (Close CoupledTM) for a particular EAW loudspeaker system. If you have any questions please contact an authorized EAW sales agent or the factory to be certain that you have correctly configured the processor to your system.
