We always quote 'real world' performance figures (measured to the AES17 standard). Some companies choose to quote chipset performance, which is misleading, and here's why.
EIN: -128dB with 150 Ohm terminating impedance at 60dB of gain
Noise: -97dBu
THD: 0.001% with -20dBu 1kHz input and 20Hz?22kHz bandpass filter
Compressor (VCA mode)
Threshold Range: -28dB to +12dB
Ratio: 1.5:1 to 10:1
Slope: Soft knee
Attack: 100? to 100ms
Release: 100ms to 7s, variable or auto (program dependent)
Compressor (Vintage Opto mode)
Threshold Range: -28dB to +12dB
Ratio: 1.5:1 to 5:1 in Comp mode, 5:1 to 20:1 in Lim mode
Slope: Soft knee in Comp mode, Hard knee in Lim mode
Attack: Fixed
Release: Fixed
EQ
Low Pass Filter: 18dB/oct from 400Hz to 22kHz
High Pass Filter: 18dB/oct from 20Hz to 1k6Hz
Parametric section is comprised of: Low-mid & Hi-mid parametric, each with continuously variable boost/cut with centre detent, frequency sweep control with two ranges, and fully variable Q. Low-mid frequencies 40Hz to 400Hz (120Hz to 1k2Hz when x3 is pressed). Hi-mid frequencies 600Hz to 6kHz (1k8Hz to 18kHz when x3 is pressed)
Shelving section is comprised of: High Frequency Shelf: The frequency range steps are 1.5kHz, 3.3kHz, 6.8kHz and 15kHz (2.2kHz, 4.7kHz, 10kHz and 18kHz when Hi Range is engaged). Low Frequency Shelf: The frequency range steps are 20Hz, 56Hz, 160Hz and 460Hz (33Hz, 95Hz, 270Hz and 655Hz when Hi Range switch is engaged)
