or cut on 1/3-octave center frequencies
• 13-LED resolution of boost or cut per frequency band
• Standard 1-U rack mount chassis
• Analog inputs and outputs with digital internal processing
• 20-20kHz frequency response (+0/-1dB), 0.008% THD,
dynamic range: 103dB (A-weighted)
• Easy-to-use / easy-to-understand user interface
• Individual signal and clip indicator LEDs per channel
• At least 25 user-definable and 25 recallable preset curves
(preset 0 should be “bypass” or “flat” curve)
