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)
