D-2000 System Specification

CobraNet was developed by Cirrus Logic, a US company and is a network protocol utilizing Ethernet networks to perform high-quality multi-channel digital transmission. It allows using existing Ethernet equipment such as CAT-5 switching hubs.

Auto-mixing advantages
NOM (Number of Open Microphones) - automatically adjusts output level based on the total number of open microphones.Ducker function (Auto-Mute function) - automatically works to attenuate outputs of channels with low priority.
Highly effective feedback suppression.
The D-2000 Series provides feedback elimination for up to 4 channels.
In addition, each channel can control 12 problem frequencies. This
makes it convenient for feedback suppression in different areas of the
same hall. 2 versatile suppression modes.Either presettable Auto Mode or realtime Dynamic Mode can be selected to suit the situation and eliminate feedback.
Essential audio processing
Delay, High-, Low-Pass and Notch Filters, Parametric Equalizers, Compressor/Auto Leveller, Gate, Crossovers and Crosspoint Gain.
32 preset memories for user convenience.
Up to 32 different routing and parameter configurations can be stored in memory and called up to handle venues such as multi-purpose halls
and conference rooms that require frequent changes in staging,seating and speaker arrangements.
Intuitive GUI
The dedicated software’s graphic, visually attractive user interface
helps streamline settings and adjustments.
Mixing console option
The D-2008SP can be connected via network to the D-2012C mixing console with 12 motorized faders and 8 rotary encoders. This enables simplified mixing operation that suit non-professional users. Using the D-2012C, allows input and output channel signal levels to be monitored,volume changes made as well as recalling preset memory settings, and contact control.
VCA control
D-2000 Series units used in conjunction with the optional D-911 VCA
Fader Unit provides more of an analog mixer user interface.
RS-232C control
The RS-232C port allows external control when connected to external
devices such as AMX*1 and Crestron*2 control units. This also allows full control over venue lighting and power curtains (blackout) from a central remote location. This feature is particularly suited for AV presentation rooms, conference rooms and hotel banquet rooms.

The D-2012C, allows input and output channel signal levels to be monitored,
volume changes made as well as recalling preset memory settings, and contact control.

A dedicated VCA fader unit that significantly expands the operational scope of the D-901 Digital Mixer. It adds useful control capabilities when connected to the D-984VC. In such a connection setup, full VCA operation becomes possible, allowing all the D-901's
12 inputs and 8 outputs channel gain levels and 8 contact controls.
