Viking 7.5 Minute Digital Voice / Promotion-on-Hold Announcer - DVA-2WA

Viking Electronics DVA-2WA Digital Voice Announcer with Built-In Amplifier

Overview

The Viking Electronics DVA-2WA is a wall-mountable digital voice and promotion-on-hold announcer built for commercial lobbies, retail floors, warehouses, and any facility needing reliable, self-contained audio messaging. With 7.5 minutes of recordable digital memory and a built-in 2-watt amplifier, the DVA-2WA handles everything from door-entry greetings to multi-zone paging — without a separate amp rack. It accepts both 120VAC and 12VDC power inputs, making it equally at home in a wired electrical closet or a battery-backed access control panel. Viking's Viking Electronics product line has long targeted integrators who need telephony and paging solutions that install cleanly with minimal hardware overhead.

Key Features

• 7.5-Minute Recordable Memory: Enough runtime for multi-message rotation — hold announcements, emergency instructions, and promotional content can all coexist without file juggling. Sampled at 64K equivalent for voice-grade clarity across the 100–3.4 kHz frequency range.
• 2-Watt Built-In Amplifier: Drives up to three 8-ohm speakers directly — no external amplifier needed for small-to-medium zones. The 2.66-ohm minimum speaker impedance floor keeps the output stage stable under typical multi-speaker parallel loads common in commercial paging systems.
• Flexible Audio I/O: Audio input accepts 30mV–1.0V RMS, covering both low-level mic sources and line-level inputs from phone systems or music servers. Output is 0.3V RMS maximum — sized correctly to feed downstream amplifiers or phone system MOH ports without overdriving them.
• Dual Power Input (120VAC / 12VDC): The 500mA AC adapter and 12VDC option let you power the unit from a standard outlet or integrate it directly into a 12V access control or paging panel. This dual-supply design eliminates a separate power supply in most panel installations and is UL listed.
• 4,000 ft Remote Trigger Wire Run: The remote trigger can be wired up to 4,000 feet away — practical for large warehouse or campus deployments where the trigger source (door contact, motion sensor, push button) is far from the announcer chassis. The IO COM wire run supports up to 1,000 feet, suitable for most building-wide distributed installs.
• Compact Form Factor: At 5.25″ × 3.5″ × 1.75″, the DVA-2WA fits inside a standard enclosure or mounts directly to a wall without consuming rack space. Useful in telecom closets and access control panels where space is at a premium.
• Wide Humidity Tolerance: Rated 5%–95% non-condensing, covering both climate-controlled offices and less-regulated storage or industrial spaces. Operating temperature range of 32°F–90°F covers most indoor commercial environments without supplemental heating or cooling.

Integration & Compatibility

The DVA-2WA is compatible with Viking 25AE paging amplifiers and supports up to three 8-ohm speakers wired in parallel. For facilities requiring telephone entry or door intercom integration, the unit's trigger input and IO COM interface make it straightforward to link to most access control panels. The analog audio output at 0.3V RMS feeds cleanly into phone system music-on-hold ports, making it a direct drop-in for on-hold messaging without additional impedance matching hardware. For larger multi-zone deployments, pair the DVA-2WA with a distributed paging amplifier to extend coverage beyond the built-in 2W output stage.

Frequently Asked Questions

Q: How many speakers can the DVA-2WA drive directly?

A: Up to three 8-ohm speakers can be connected to the built-in 2-watt amplifier. The minimum speaker impedance is 2.66 ohms, which corresponds to three 8-ohm speakers wired in parallel.

Q: What is the maximum recording time on the DVA-2WA?

A: The DVA-2WA provides 7.5 minutes of recordable digital memory, sampled at a 64K equivalent rate for voice-grade audio across a 100–3.4 kHz frequency response.

Q: Can the DVA-2WA be triggered remotely?

A: Yes. The remote trigger input supports wire runs up to 4,000 feet, making it suitable for large facilities where the trigger source — a door contact, motion sensor, or push button — is located far from the announcer unit.

Q: What power sources does the DVA-2WA accept?

A: The DVA-2WA accepts both 120VAC (via a 500mA UL-listed adapter) and 12VDC, allowing integration into standard electrical circuits or 12V access control and paging panels without a separate power supply.

Q: Is the DVA-2WA suitable for music-on-hold applications?

A: Yes. The 0.3V RMS audio output level is sized to feed phone system MOH ports directly. The 30mV–1.0V RMS input range also accepts line-level sources from PBX or key systems for pass-through hold audio.

Q: What are the installation dimensions of the DVA-2WA?

A: The unit measures 5.25″ × 3.5″ × 1.75″ (133mm × 89mm × 44mm), compact enough to mount inside a standard enclosure or directly on a wall in a telecom or access control closet.

The DVA-2WA is one of those units that earns its keep by doing exactly what it says without requiring support hardware. The 4,000-foot remote trigger wire run is the spec I point to first — in a distribution center or multi-building campus, that reach means you can position the announcer chassis wherever power is convenient and still trigger it from a door contact or motion sensor on the far end of the facility.

Technical Highlights:

• 7.5-Minute Memory at 64K Sampling: Adequate for rotating hold messages, door-entry greetings, and emergency tone sequences within a single unit — no external media or network dependency for playback.
• Dual 120VAC/12VDC Input: The 500mA UL-listed adapter plus 12VDC input means you can power this directly off an access control panel's aux supply. Eliminates a wall-wart in most panel installs.
• 0.3V RMS Audio Output: Matches phone system MOH input levels without a pad or impedance transformer. The 30mV–1.0V RMS input range is wide enough to accept mic-level and line-level sources interchangeably.

Deployment Considerations:

• The built-in amp tops out at 2 watts peak driving a 2.66-ohm minimum load — fine for a three-speaker lobby or entry vestibule, but plan a separate distributed amp if you need more than three zones or higher SPL in a large open space.
• Operating temperature ceiling is 90°F — confirm ambient temps in equipment closets that lack active cooling before installing, especially in southern climates where unconditioned telecom rooms can exceed this in summer.

For a retail or medical office environment needing on-hold messaging plus door-chime announcements from a single compact unit wired into an existing 12V panel, the DVA-2WA (sometimes searched as DVA 2WA) is a clean, low-overhead solution that doesn't require an amplifier rack or a separate power circuit.
