Description
The D-901 from TOA Electronics is a digital mixer/processor, and an ideal solution for a wide variety of installed sound applications, including audio/visual facilities, houses of worship and many others. The unit can be programmed from the front panel, or via PC control software for Windows. Settings can be stored in the unit’s internal memory and can be recalled using front-panel controls.
The digital mixer can be configured with up to twelve inputs, eight buses, and eight outputs. It features all the signal processing functions necessary for sound systems that require feedback suppression, dynamics and EQ, crossovers, delays and auto-mixing. However, the exact configuration of input, output and control functions are left to the end-user. Sixteen modules are available.
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
