Tuner Audac DMP42 — modular DAB/DAB+ and FM tuner with SourceCon™ connector

Audac DMP42 is a modular DAB/DAB+ and FM tuner designed for professional audio systems. The unit provides both digital and analog broadcast reception and connects via a SourceCon™ connector for quick mounting and hot‑swapping in compatible racks or controllers. It is intended as a dedicated radio source module for commercial audio installations, background music systems, public buildings and venues that require a stable and easy-to-integrate radio input.

Advantages

The DMP42 supports DAB/DAB+ digital radio and FM reception, offering broad coverage of broadcast sources in one compact module. The SourceCon™ connector enables tool-free insertion and removal in compatible chassis or controllers, simplifying service and upgrades. Its design focuses on reliable reception and easy system integration, making it suitable for continuous operation in professional environments.

Suitable for

• Commercial background music systems
• Retail stores, restaurants and hospitality venues
• Public buildings, offices and conference facilities
• Installations requiring hot‑swappable radio sources in a rack or controller

When it may not be suitable

The DMP42 is a modular radio source intended for use with compatible Audac racks, controllers or mounting systems; it does not function as a standalone consumer radio with built-in amplification or loudspeakers. If you need a full-featured standalone tuner with integrated user interface, display and speaker output, a dedicated tabletop or shelf stereo tuner would be more appropriate.

Key specifications

• Reception: DAB/DAB+ and FM broadcast bands
• Connectivity: SourceCon™ module form factor for compatible rack/controller insertion
• Mounting: modular insertion and hot‑swap capability in supported chassis
• Intended use: professional fixed installations and background music systems
• Operation: designed for continuous use in commercial environments

How to use

Install the DMP42 into a compatible Audac rack, controller or mounting slot using the SourceCon™ connector. Follow the host device instructions to secure the module and establish audio routing within the system. Use the host controller or rack interface to select radio sources, tune stations and adjust level or routing as required. For best reception, connect an appropriate external antenna to the host chassis or antenna input provided by the rack.

What to consider before purchase

• Requires a compatible chassis, rack or controller that accepts SourceCon™ modules.
• Does not include built-in amplification, speakers or standalone controls—requires host system for operation.
• Ensure availability of suitable antenna connections and signal strength at the installation site.

Usage recommendations

For reliable reception, use a professionally installed antenna and verify signal levels at the rack location before final installation. Keep spare modules for critical installations that require minimal downtime, and follow routine maintenance and firmware update recommendations provided by the system controller.
