The TOA DT-940 AM/FM Stereo Tuner is a professional broadcast tuner designed for commercial and installed audio systems that need reliable access to AM and FM radio programming. With 40 station presets, automatic station scanning, direct frequency entry, and both stereo and mono audio outputs, the DT-940 provides a flexible source for background music, foreground music, news, and other broadcast content.

Designed to integrate with commercial mixers, amplifiers, and distributed audio systems, the DT-940 provides straightforward operation in a compact rack-friendly chassis. Its frequency-synthesized tuning system helps provide stable station reception, while the large front-panel display makes it easy to monitor the selected station and operating mode.

The DT-940 is a practical choice for restaurants, retail locations, offices, hotels, schools, public facilities, and other commercial environments where broadcast radio is part of the audio system.

40 AM/FM Presets for Easy Station Selection

The DT-940 provides memory for 40 radio stations, with:

• 20 AM presets
• 20 FM presets

Stations can be selected using several tuning methods, including:

• Automatic station scanning
• Manual tuning
• Direct frequency entry
• Preset station recall

This makes it easy for staff to switch between frequently used stations without manually searching for the desired frequency.

Automatic Preset Tuning

The Automatic Preset Tuning (APT) function can automatically scan the available AM and FM bands and store stations in memory.

Up to 20 AM and 20 FM stations can be stored, providing a quick way to configure the tuner when it is first installed.

Clear Digital Display

The DT-940 features a large digital LCD display that provides useful information about the current radio selection and tuner operation.

The display can show information such as:

• Selected frequency
• AM or FM band
• Preset number
• Tuning mode

The straightforward front-panel layout makes the tuner easy to operate without complicated controls or menus.

Stereo and Mono Audio Outputs

The DT-940 provides multiple output options for integration with commercial audio equipment.

Audio connections include:

• Stereo RCA line-level output
• Mono balanced output through an M3 screw terminal

The stereo output is useful when the system is designed to reproduce music in stereo, while the mono output can be useful in commercial distributed audio systems where a single combined signal is preferred.

This allows the tuner to integrate with a variety of commercial mixers, amplifiers, and audio distribution systems.

Designed for Commercial Audio Systems

The DT-940 is designed to operate as a dedicated audio source within a larger sound system rather than as a consumer home stereo component.

It can be used as a radio source for:

• Background music systems
• Foreground music systems
• Restaurants
• Retail stores
• Offices
• Hotels and hospitality facilities
• Schools
• Public buildings
• Commercial distributed audio systems

For installations where radio programming is regularly used as part of the audio system, a dedicated tuner provides a simple and reliable source that can remain connected to the system.

Frequency-Synthesized Tuning

The DT-940 uses frequency-synthesized tuning for precise station selection.

The available tuning ranges are:

FM: 87.9–107.9 MHz in 100 kHz steps

AM: 520–1710 kHz in 10 kHz steps

The tuner also provides an FM antenna input using a 75Ω F-type connection and an AM antenna connection supporting the supplied loop antenna or a compatible external antenna.

Easy Rack Installation

The DT-940 uses a compact chassis measuring approximately 16.54 inches wide, allowing it to integrate easily with other professional audio equipment.

An optional MB-15B rack mount kit is available for rack installation.

The front panel features a black aluminum finish, while the chassis uses a black pre-coated steel construction designed to complement commercial AV equipment.
