mastering
s4 concurrently selectable EQ modules (31-band graphic EQ, 10-band parametric EQ, Feedback Destroyer
plus three Dynamic EQs per stereo channel)
sFlexible Compressor/Expander function with Peak Limiter per stereo channel as well as additional Stereo
Imager and Stereo Delay for delay line applications
sUnique VPQ (Virtual Paragraphic EQ) option allows parametric control of graphic EQs
sUltra high-resolution 61-band real-time FF Analyzer with additional auto EQ function for room and loudspeaker
equalization
sMulti-functional level meters (peak/RMS, VU and SPL meter with dBA/dBC weighting via R A mic input)
s64 user memories for complete setups and/or individual module configurations
sSeparate R A mic/line input with phantom power, professional wordclock input and MIDI connections for
full remote control, preset dumps and system updates
sUltra high-quality AKM® 24-bit/96 kHz A/D- and D/A converters (113 dB dynamic range)
sOpen architecture allowing future software updates via MIDI
swo high-performance 32/40-bit floating-point SHARC® digital signal processors for ultimate sonic resolution
sBalanced inputs and servo-balanced outputs with gold-plated XLR connectors, stereo aux output,
AES/EBU and S/PDIF inputs and outputs (XLR and optical)
sInternal switch-mode power supply for maximum flexibility (100 - 240 V~), noise-free audio, superior transient
response and lowest possible power consumption
sManufactured under ISO9000 certified management system
