AtlasIED DMA-ML DMA Active Mic/Line Input Wall Plate

The AtlasIED DMA-ML and AtlasIED WTSD-ML are professional mic/line preamp wall plates designed for commercial audio systems requiring clean, high-gain microphone or line-level input at the wall. Part of the AtlasIED DMA Digital Mixer Amplifier accessory line and WTSD active wall plate series, these units provide flexible, low-voltage audio integration for restaurants, schools, hospitality venues, and multi-purpose facilities.

Two versions are available to suit different system designs:

• DMA-ML – Direct connection to AtlasIED DMA Series amplifiers

• WTSD-ML – Universal mic/line preamp for any system with a balanced line input

Both models share the same high-performance mic/line receiver platform, ensuring consistent audio quality and streamlined installation.

Flexible Integration for Commercial Audio Systems

DMA-ML – Direct to DMA Amplifiers

The DMA-ML connects directly to a DMA amplifier using industry-standard Cat5/6 cabling and RJ45 connectors. The installer-friendly, color-coded wiring system simplifies setup and reduces installation time.

• Plug-and-play integration

• Mount up to 330 ft (100 meters) from the amplifier

• Onboard adjustable signal limiter (–3 dB to +21 dB)

• Front-panel signal and limiter indicators

This makes it ideal for podium microphones, wall inputs in classrooms, and hospitality spaces where remote mic access is required.

WTSD-ML – Universal Mic/Line Preamp

The WTSD-ML functions as a standalone balanced mic/line preamplifier, compatible with virtually any audio system featuring a balanced line input.

• Requires PWBOB analog interface box

• Requires external power supply

• High-gain balanced line output for long-distance runs

• Install up to 100 meters (330 ft) from connected equipment

This version provides system designers with maximum flexibility beyond DMA-based systems.

Commercial-Grade Microphone Preamplifier

Both wall plates feature premium microphone preamp circuitry designed for professional environments:

• Ultra-low noise performance

• Mic or line level selection

• Phantom power (for condenser microphones)

• 20 dB mic pad

• 120 Hz high-pass filter (defeatable)

• Rotary detented level control

• High-gain balanced output

These features ensure clean, controlled audio for speech, paging, announcements, and presentation applications.

WTSD Bus Architecture & Daisy-Chaining

The proprietary AtlasIED WTSD low-voltage bus supports flexible expansion:

• Single or multiple WTSD wall plates on the same bus

• Up to three WTSD devices daisy-chained

• Audio from each device summed together

• Independent control maintained per device

This architecture is ideal for facilities that require multiple microphone or input locations while maintaining centralized amplifier management.

 

Installer-Friendly Design

Both models are designed for quick and code-compliant installation:

• Fits standard 1-gang electrical boxes

• Compatible with low-voltage rings

• Requires only 1.5 inches (38 mm) mounting depth

• Surface-mount design (no cover plate required)

• Meets low-voltage electrical codes

The slim profile and flexible mounting options make them suitable for new construction or retrofit installations.

AtlasIED DMA-ML Key Features
