ULTRAGRAPH DIGITAL
Digital Stereo 31-Band 24-Bit 96 kHz Equalizer Feedback Destroyer Dynamics Processor
sUltra high-resolution processor for all EQ, RT and dynamic applications, especially for P and audiophile
mastering
sUnique TRUE CURVE Functionwhat you see on the faders is what you get as frequency response
sRevolutionary FBQ DETECTION system instantly reveals critical frequencies and can also be used as
udio nalyzer
sutomatic 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
sdditional sweepable high and low cut filters for removal of unwanted frequencies like floor rumble and high-
frequency noise
sIntegrated Pink Noise generator for perfect room and loudspeaker equalization
sDigital ES/EBU and S/PDIF interface and selectable sample rates (44.1, 48, 96 kHz)
sUltra high-resolution 24-bit/96 kHz /D- and D/ converters and high-performance 24/48-bit MOTOROL ®
DSP for ultimate sonic resolution
sRelay-controlled hard-bypass with an auto-bypass function during power failure (failsafe relay)
sHighly accurate, 2 x 12-digit LED meters for easy input and output level setting
sUltra high-quality, illuminated 45-mm faders, sealed rotary controls and illuminated switches
sServo-balanced inputs and outputs on gold-plated XLR and ¼" TRS connectors
sInternal switch-mode power supply for maximum flexibility (100 - 240 V~), noise-free audio, superior transient
response and lowest possible power consumption
sExtremely rugged construction ensures long life even under the most demanding conditions
sDesigned in Germany. Manufactured under ISO9000 certified management system
