Technical Data

• Number of filter channels       20
• Spectralrange       100Hz ...8000Hz

Powering:

• Automatic selection of Line voltage
  • 110 V +/- 15%
  • 220 V +/- 15%
• Power consumption.       Approx. 18 Watts

Speech or Signal Inputs:

• Line input   + 6 dBm / 100 K ohm unbalanced
• Microphone input for low-impedance balanced dynamic microphones
  (may be switched off) (2.5 mV, 5 K ohm)

Replacement Sound Inputs:
For voiced replacement signals:

• Two line inputs 0 dBm unbalanced 100 K ohm

• One microphone input       2.5 mV, unbalanced 5 K ohm
  

• Mix these 3 inputs internally.
  

• For unvoiced replacements signals:
  

• Two line inputs 0 dbM unbalanced 100 K ohm

Mix these two inputs internally
Modulation Controls

Output Signals

• Balanced, line (Tuchel)     + 6 dBm
• Unbalanced, line (phone jack)     + 6 dBm

Control Potentiometers

• 20 x Variable channel Emphasis, individually for each filter channel
  
• 20 x Speech Addition/Multifilter, individually for each filter channel
  
• 1 x Speech Addition, simultaneously for all channels
  
• 10 x Silence Bridging, one control for two adjacent channels
  
• 1 x Silence Bridging, simultaneously for all channels
  
• 1 x Bypass for speech, disregarding the volume control, or Bypass for voiced replacement signal through volume control.
  
• 1 x Output Volume
  
• 1 x Speech/Pause detector threshold
  
• 1 x Pause-filling characteristic of the Bypass for voiced replacement signal (control accessible at back panel)
