The TASCAM MM-2D is a compact bidirectional Dante converter with two balanced analogue microphone/line inputs, two balanced analogue line outputs and four-channel Dante input and output.

Its built-in DSP and 6-input/4-output matrix mixer allow analogue and Dante sources to be processed, mixed and routed without requiring a separate hardware mixer or external DSP processor. It is designed for conference rooms, restaurants, retail stores, broadcast facilities, educational venues and other professional network-audio installations.

Channel Configuration

Analogue inputs:

• Two mic/line channels

Analogue outputs:

• Two line-output channels

Dante network audio:

• Four Dante inputs
• Four Dante outputs

DSP matrix:

• Six input sources
• Four mix outputs

The six matrix sources consist of the two analogue inputs and four Dante input channels. The resulting mixes, direct inputs and Dante sources can be routed to the two analogue outputs and four Dante outputs.

Analogue Mic/Line Inputs

Each analogue input can receive microphone-level or line-level audio.

Input specifications:

• Minimum input level: −74 dBu
• Maximum input level: +26 dBu
• Input impedance: 2 kΩ or higher
• Phantom power: 48V
• Remotely adjustable microphone gain

Connector type:

• MM-2D-E: Balanced 3.81 mm Euroblock
• MM-2D-X: Balanced three-pin XLR

Analogue Line Outputs

The MM-2D provides two independently processed balanced line outputs.

Connector type:

• MM-2D-E: Balanced 3.81 mm Euroblock
• MM-2D-X: Balanced three-pin XLR

Output impedance:

• 200Ω or lower

Selectable maximum output levels:

• +15 dBu
• +18 dBu
• +20 dBu
• +22 dBu
• +24 dBu

The selectable reference levels help the converter integrate with consumer, professional and broadcast audio equipment.

Input DSP Processing

Each analogue input includes:

• Mic/line selection
• 48V phantom power
• Microphone gain
• Input trim
• Phase inversion
• Four-band equaliser
• Compressor
• Automatic level control
• Digital fader
• Mute

These settings are controlled remotely using compatible TASCAM software.

Matrix Mixer

The built-in 6-input/4-output matrix mixer can combine:

• Analogue Input 1
• Analogue Input 2
• Dante Inputs 1–4

The matrix mixer provides:

• Independent source levels
• Flexible output routing
• Digital faders
• Mute controls
• Automatic ducking
• Ambient Noise Compensation

Ducking can lower background music when a priority microphone becomes active. Ambient Noise Compensation can automatically adjust an output level according to changing environmental noise.

Output DSP Processing

Output processing includes:

• Ten-band equaliser
• High-pass filtering
• Low-pass filtering
• Adjustable delay
• Limiter
• Phase inversion
• Output fader
• Mute
• Fader and mute grouping

Each output can be processed independently to match its connected amplifier, powered speaker or room zone.

Dante Network Audio

Network connections:

• DATA: RJ45
• DATA+PoE: RJ45

Network standard:

• Gigabit Ethernet
• 1000BASE-T
• IEEE 802.3ab

Recommended cable:

• Shielded Cat5e or higher

The two network ports support switched daisy-chain operation, allowing compatible Dante devices to be connected without a separate network switch in smaller systems.

AES67 and Dante Domain Manager

The MM-2D supports Dante AES67 mode for integration with compatible AES67 and Ravenna network-audio systems.

It is also compatible with Dante Domain Manager for managed Dante networks requiring user authentication, system segmentation, remote monitoring and enhanced security.

Control Software

TASCAM DCP Connect

DCP Connect provides detailed system configuration for installers and system integrators.

It can control:

• Input gain and phantom power
• Input and output DSP
• Matrix mixing
• Dante and analogue routing
• Scene presets
• Output levels
• Mute settings
• Signal monitoring

TASCAM EZ Connect

EZ Connect provides simplified daily controls for end users, such as:

• Source selection
• Zone-volume adjustment
• Mute
• Preset selection

The installer can restrict which controls are available to end users.

Scene Presets

Up to 50 scene presets can be stored.

A scene can contain:

• Input settings
• DSP parameters
• Matrix-mixer levels
• Routing
• Output processing
• Fader positions
• Mute states

This allows the system to be quickly reconfigured for different room layouts, events or operating conditions.

External Control on MM-2D-E

The Euroblock version provides additional external control connections.

These can be used for functions such as:

• Input muting through an external switch
• Output-volume control using a compatible external potentiometer
• External LED-status indication

These connections are available on the MM-2D-E and are not provided on the MM-2D-X.
