TASCAM MM-4D/IN-E
Brian Long
Introduction
The TASCAM MM-4D/IN-E is a compact four-channel mic/line input converter that brings professional analog sources into a Dante network. Four balanced Euroblock inputs feature TASCAM microphone preamps, remotely adjustable gain, and +48V phantom power, making the unit suitable for microphones, mixers, wireless systems, and other analog sources in permanent AV installations.
More than a basic analog-to-Dante interface, the MM-4D/IN-E incorporates a DSP matrix mixer with input EQ and dynamics, ducking, ambient noise compensation, flexible routing, and scene storage. Four Dante input and four Dante output channels allow the processor to participate in a larger networked audio system, while PoE, AES67 support, Dante Domain Manager compatibility, and software-based remote control make it particularly useful for conference facilities, education, houses of worship, hospitality, corporate AV, theaters, and other installed audio environments.

Features
- Four Mic/Line Inputs: Converts up to four professional analog microphone or line-level sources to Dante network audio.
- Balanced Euroblock Connections: The MM-4D/IN-E uses installation-friendly Euroblock connectors for its four balanced analog inputs.
- Four Dante Inputs and Four Dante Outputs: Provides 4 × 4 Dante network audio connectivity for flexible routing and DSP applications.
- Analog-to-Dante Conversion: Converts connected microphones and line-level sources directly to Dante for routing across standard Ethernet infrastructure.
- Up to 96kHz / 24-Bit Audio: Supports professional network audio at sampling frequencies up to 96kHz with 24-bit resolution.
- TASCAM Microphone Preamps: High-quality microphone preamps provide clean amplification for professional microphone sources.
- Wide Mic/Line Input Range: Supports input levels from low-output microphones through professional line-level equipment.
- +48V Phantom Power: Each microphone input can provide phantom power for compatible condenser microphones.
- Remote Gain Control: Microphone preamp gain can be configured remotely through supported TASCAM control software and compatible control systems.
- Integrated DSP Mixer: Built-in processing provides signal conditioning, mixing, and routing without requiring a separate DSP processor for many applications.
- Eight Available DSP Sources: The internal processing environment can work with the four analog mic/line inputs and four Dante input channels.
- Flexible Matrix Routing: Analog inputs and DSP mixer outputs can be assigned to Dante output channels according to system requirements.
- Matrix Mixer Bypass: The unit can also operate as a straightforward mic/line-to-Dante input interface by bypassing the matrix mixer.
- Four-Band Input EQ: Individual input equalization provides tonal adjustment and corrective processing.
- Input Compression: Integrated dynamics processing helps control sources with wide level variations.
- Automatic Level Control: Built-in processing can help maintain consistent program levels when source volume varies.
- Input Phase Control: Individual input phase settings assist with microphone and system alignment.
- Input Fader and Mute: Each input can be level-controlled or muted within the DSP environment.
- Ducking: Priority audio can automatically reduce the level of selected program sources, making the MM-4D/IN-E useful for announcements and paging applications.
- Ambient Noise Compensation: Detects changes in environmental sound level and can automatically compensate program levels accordingly.
- 50 Scene Presets: Store and recall system configurations for different room arrangements, events, or operating modes.
- SNTP-Based Timer Events: Stored scenes can be triggered by timer events for automated operation.
- Dante Controller Support: Audinate Dante Controller provides network routing and Dante device configuration.
- AES67 Support: AES67 mode enables interoperability with compatible AES67 network audio systems.
- Dante Domain Manager Support: Compatible with Dante Domain Manager for managed and enterprise Dante environments.
- Dual Gigabit Ethernet Ports: Two RJ-45 network connections provide Dante networking and flexible system connectivity.
- 1000BASE-T Ethernet: Gigabit Ethernet provides professional low-latency network audio transport.
- PoE Support: PoE Class 0 allows compatible Ethernet infrastructure to carry both Dante audio and operating power.
- Optional AC Power: The unit can alternatively be powered using a compatible TASCAM external AC adapter.
- DC Power Daisy-Chaining: Compatible units can share external DC power in supported installation configurations.
- TASCAM DCP CONNECT Support: Provides system integrators with access to detailed DSP, routing, scene, and device settings.
- TASCAM EZ CONNECT Support: Offers simplified end-user access to selected system controls without exposing detailed installation settings.
- External Control Integration: Network control capabilities allow the MM-4D/IN-E to participate in larger professional AV control systems.
- Compact Half-Rack Design: A 1U-high, half-rack-width enclosure provides four microphone inputs, DSP, and Dante networking while conserving rack space.
- Flexible Mounting: Included mounting hardware supports installation beneath desks, tables, lecterns, and other suitable surfaces.
- Optional Rack Installation: The TASCAM AK-RS1 rack shelf supports conventional rackmount installation.
- Euroblock Version of the MM-4D/IN Platform: Designed specifically for fixed installations where secure, compact terminal-block analog connections are preferred.
