Modular Digital Mixer, Up to 12 Mic/Line Inputs/8 Line Outputs

The D-901 DIGITAL MIXER is the ideal solution for a wide variety of installed sound applications including audio/visual, houses of worship and many others. The D-901's modular design supports up to twelve mic/line inputs and eight line outputs with flexible RS-232 or contact-closure remote control. Audio processing tools include automixing, feedback suppression, multi-band parametric filters, compressors, limiters, noise gates, crossovers, delays and more. Full input-to-output matrixing allows users to store and recall any input to output combination for multi-zone or room-combining applications. The unit can be programmed via the front panel display or with configured off-site with PC control software for later uploading. The D-901 is covered with a five year product warranty.

D-901 features include:

  • Rack-mount digital mixer/processor for installed sound applications such as audio/visual facilities, houses of worship, and others
  • Modular design allows versatile configurations - up to twelve inputs and eight outputs (modules not included)
  • Audio processing tools include a digital mixer, feedback suppression, auto mixing, parametric EQ, compression, delay and echo
  • Feedback suppressor automatically processes feedback at certain frequencies through constant monitoring then automatically attenuates only the precise problematic frequencies, keeping the audio sounding natural
  • Ducker automatically adjusts all channel gains in response to input signal level
  • NOM (Number of Open Microphones) Attenuation automatically adjusts the input gain of open microphones corresponding to the number of open microphones in the system
  • Eight-bus matrix allows flexible input-to-output signal routing for zoning or room-combining
  • All settings can be performed at the unit using the LCD screen and setting keys and knobs located on the front panel
  • PC software for offsite programming and archiving settings
  • Sixteen internal memories for storage and recall of different signal routing and parameter configurations
  • An RS-232C port permits remote control of the unit using an AMX or Crestron controller, or similar external equipment
  • The use of an optional D-981 or D-983 Remote Control Module, or an optional D-984VC VCA Control Module permits easy remote operation of volume control and preset memory recall
  • The use of an optional D-984VC VCA Control Module permits the sound volume to be adjusted from remote locations using the faders or volume controls
  • Input and output channel metering
  • A protect function prevents accidental changes of front panel key settings
