Digital Stereo Mixer

The M-633D is a stereo mixer equipped with 12 input channels (6 monaural inputs and 3 stereo inputs) and 6 output channels (2 monaural outputs, 1 stereo output, and 1 stereo recording output). It has 2 monaural channel and 1 stereo channel bus lines, allowing each input signal to be assigned to each bus line individually. 1 Stereo input is located on the front panel for easy connection of audio/MP3 players.

It features digital signal processing functions such as Automatic Resonance Control function (ARC), Feedback Suppressor function (FBS), Automatic Clipguard function (ACG), and Automatic Mute function (AUTO MUTE). It performs advanced acoustic compensation by means of automatic processing without the use of an acoustic measuring instrument. It can be mounted in an EIA component rack (1U size).

Digital Matrix Mixer

The NEW TOA M-9000M2 Digital Matrix Mixer redefines the mixer category, by combining a modular matrix mixer and digital signal processor (DSP) in a compact two-rack package. This versatile new modular unit is ideal for multi-zone paging, music distribution and room-combining applications.

The M-9000M2 combines an enhanced GUI programming interface with exceptional audio quality.

The M-9000M2 enables easily configured custom systems with up to eight mic/line inputs and eight outputs. The M-9000M2 has two output channels with built-in DSP, including ten-band parametric EQ, compressor, delay, and more.

Input and output modules include additional DSP. A new integrated operating mode provides powerful functionality for both simple mixing and complex multi-zone paging applications. Features include telephone zone paging, automatic microphone mixing and ambient noise control.


D-2008SP Digital Mixing Processor Unit

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.


D-2000 System Specification

The D-2000 Series is expandable to a massive 128 input input/output configuration,it also includes various modules and can be combined to create the best possible sound in small to medium size venues of all types, including hotel banquet and function rooms,indoor sports facilities, multipurpose halls,places of worship and many others.


Modular Digital Signal Processor with Automatic Resonance Control

The DP-K1 DIGITAL MIXER / PROCESSOR is the ideal solution for a wide variety of installed sound applications including houses of worship, sports facilities, convention centers, airports, and many others. The DP-K1's modular design supports up to eight mic/line inputs and eight line outputs with flexible contact-closure remote control.

The advanced new Automatic Resonance Control (ARC) measurement and processing algorithm from TOA, improves speech intelligibility and sound quality in facilities with challenging acoustic environments. ARC automatically identifies room mode frequencies and applies an inverse response curve to compensate for the measured room response.

Additional audio processing tools include 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 is programmed via PC control software and includes a built-in network interface for remote access.


Digital Ambient Noise Controller

Digital audio processor adjusts BGM/announcement sound volume to match changes in listening area noise levels.

The TOA DP-L2 Digital Ambient Noise Controller is the easy, automatic solution to the problem of keeping BGM and announcements audible and understandable when the ambient noise levels at an airport check-in counter or boarding gate, or a shopping mall, restaurant or pub, are higher because a large number of people are present. Furthermore, the DP-L2 also works to keep music and information audio from reaching levels that are irritating to customers and staff when the surrounding ambient noise levels are not so high.


Modular Digital Mixer

  • The new TOA D-901 Digital Mixer is a fully modular, cost-effective digital mixer featuring a 12-input, 8-bus, 8-output channel configuration (12 x 8 matrix) with easy operation that can be expanded as applications require.
