Ceiling-mounted directional audio speaker for focused messages, product information and sound zones in commercial spaces.
ZKDigimax DG05-SA01 directional audio speaker helps commercial spaces deliver a clear audio message to a defined area without filling the wider environment with the same sound. The Sound Dome uses directional audio technology to create a more localised listening zone, making it a practical option for retail displays, receptions, cafés, galleries, hallways and other locations where a general loudspeaker would be intrusive.
For a shopper standing at a featured display, a visitor approaching reception or a customer moving through an exhibition, sound can add a useful layer of information. The DG05-SA01 is designed to direct that information towards the intended listening position while keeping spill into surrounding zones lower than a conventional broad-coverage speaker. This supports more considered use of promotional, instructional or ambient audio in shared public areas.
The Sound Dome has a stated directional angle of less than 15° at -20 dB and a maximum output of 88 ±3 dB at 2 kHz. Its directional transmission is intended to form an independent audio space, helping operators communicate in a target zone without unnecessarily disturbing people elsewhere in the room. Actual audible coverage and perceived volume depend on mounting height, ceiling construction, source material, ambient noise and the final installation setting.
Its 500 Hz to 13 kHz frequency response is suited to voice-led messages and supported audio content, with MP3 and WAV playback formats listed. A 3.5 mm AUX input and U-disk input provide practical content-source options. The 15 W rated-power design can be integrated into a specified directional-audio solution; project requirements should confirm the content source, power arrangement, mounting method and any associated audio equipment.
The DG05-SA01 measures 294 × 169 × 29 mm and weighs 0.85 kg. It uses DC 24 V, with AC 110 to 220 V listed for the power supply. The specified operating range is 15°C to 45°C at 10% to 90% RH non-condensing, so it is suited to conditioned indoor spaces rather than unprotected outdoor locations.
The brochure identifies a universal bracket, amplifier, card reader, AC adapter and audio cable as accessories. These components and their inclusion can vary by system design, so NZTeco will confirm the required hardware for the intended application. A typical configuration may link a trigger or content source through the appropriate audio equipment to the directional speaker.
Directional audio works best when the message, target position and physical environment are planned together. NZTeco can help assess ceiling height, the intended listener location, ambient sound, playback source and access to power so the resulting audio zone supports the customer experience without becoming distracting. Confirming these details early also helps determine whether any listed accessories are required for the finished installation.
Use the Sound Dome to deliver a focused product explanation near a retail shelf, an arrival message at a reception counter, an interpretation point in a museum, a guidance message in a corridor or a branded audio cue in a café. This is particularly useful where a message should be heard close to the point of engagement rather than broadcast throughout the venue.
