
VariGraph: frequencies for the bands 1 and 12 can be arbitrarily chosen (for each channel, minimum
spacing approx. 2 octaves), Q-factors as well as all intermediate bands are automatically calculated
accordingly (allows for an optimal adaption of the equalizer to each application)
Fully parametric equalizer

16 bands (4 per channel)

Frequency: 20 Hz to 20.45 kHz (each band), very good resolution of 96 steps per octave

Gain: +18 to -44 dB (each band), fine 0.5 dB steps from +18 to -20 dB

Q-factor: 0.2 to 100 (logarithmic scaling 0.2, 0.22, 0.25, 0.28, 0.32, etc.), this permits extremely
narrowband notch filters for feedback elimination without loss of sound quality
Limiter

Can be enabled separately for each channel, reliably protects the sound system from sudden,
unexpected increases in signal level that can lead to amplifier clipping or loud-speaker damage
Preset (set of programmable parameters)

Available number of presets: 20

Preset parameters: master volume, output on/off, preset name
VU meter and master volume indicator

VU meter for one channel (freely selectable), headphone connection (for monitoring) renders the
selected channel

VU meter range: 0 to -50 dB, 14 bars (0 dB corresponds to the peak output level of the DSP output)

Volume bar: renders graphic representation of the master volume
User Interface

Display: 2 lines of 20 characters each, user input via two rotary encoders with integrated pushbuttons

All settings are adjusted directly on the instrument by menu-driven user guidance (i.e. without external
PC or laptop)

Separate parameter domain (EQs, delays, etc.) and user domain (master volume, preset, channel on/off)

The parameter domain is safeguarded against unauthorised access, the safety mechanism works
without a password (eliminates the problem of forgotten passwords)

The user domain can be protected against accidental change of settings

Freely definable welcome message upon power-up (2 lines of 16 characters each)

For each channel a name can be freely defined (up to 7 characters) which appears in all relevant menus
on the display
DSP internals

ADC / DAC resolution and sampling rate: 24 bit, 96 kHz

DSP internal accuracy: 48 bit, entire data path

DSP audio clock frequency: 96 kHz, entire data path (thus, EQs are very precise at high frequencies)

DSP internal overload reserve: 48 dB (renders a DSP internal overload in conventional applications
virtually impossible)
Line

Maximum level: 100 mV (max. gain), 3 V (min. gain)

Gain: 8 mV (-40 dBu) / 430 mV (-5 dBu)
Microphone

Maximum level: 2.5 mV (max. gain), 200 mV (min. gain)
 Input impedance: 0.6 mV (-62 dBu) / 45 mV (-25 dBu) 1 dB

CMMR: > 60 dB at 1 kHz

THD level: 10 dB

Hi-pass-filter: 100 Hz, 6 dB/oct

Phantom power: + 48 V
Tape/CD

Impedance tape: 16 k

Impedance CD: 28 k

Input sensitivity tape: -12 dBu

Input sensitivity CD: -7 dB
Outputs
 Output impedance OUT 1, 2, 3, 4: 140  balanced; 70  unbalanced
