ULTRAGRAPH DIGITAL DEQ1024
Digital Stereo 31-Band 24-Bit/96 kHz Equalizer/Feedback Destroyer/Dynamics Processor
s Ultra high-resolution processor for all EQ, RTA and dynamic applications, especially for PA and audiophile mastering s Unique TRUE CURVE Functionwhat you see on the faders is what you get as frequency response
s Revolutionary FBQ DETECTION system instantly reveals critical frequencies and can also be used as Audio Analyzer s Automatic and ultra-fast Feedback Destroyer plus feedback indication via fader LEDs
s Inaudible Noise Gate/Peak Limiter function plus amazing Stereo Imager for spatial enhancement
s Additional sweepable high and low cut filters for removal of unwanted frequencies like floor rumble and highfrequency noise s Integrated Pink Noise generator for perfect room and loudspeaker equalization
s Digital AES/EBU and S/PDIF interface and selectable sample rates (44.1, 48, 96 kHz)
s Ultra high-resolution 24-bit/96 kHz A/D- and D/A converters and high-performance 24/48-bit MOTOROLA DSP for ultimate sonic resolution s Relay-controlled hard-bypass with an auto-bypass function during power failure (failsafe relay) s Highly accurate, 2 x 12-digit LED meters for easy input and output level setting
s Ultra high-quality, illuminated 45-mm faders, sealed rotary controls and illuminated switches s Servo-balanced inputs and outputs on gold-plated XLR and " TRS connectors
s Internal switch-mode power supply for maximum flexibility (100 - 240 V~), noise-free audio, superior transient response and lowest possible power consumption s Extremely rugged construction ensures long life even under the most demanding conditions s Designed in Germany. Manufactured under ISO9000 certified management system
