SPK MSK Window SQ 70V T72 XFMR

Ideal Use Cases

The AtlasIED M2000-SM is a surface-mount sound masking transducer intended for office windows and walls where sensitive conversations may be vulnerable to eavesdropping. It transfers a sound masking frequency directly to the selected surface, disrupting the ability to overhear conversations with radio or infrared microphones. Its stated purpose makes it relevant to offices, meeting areas, and other workspaces in which conversations take place near windows or walls.

This model is specifically described as a security product. Rather than functioning as a conventional loudspeaker for music or announcements, it uses the mounted surface as part of the sound masking application. The square enclosure measures 2 1/2 inches across and only 1 inch high, giving it a compact form for placement on a suitable surface.

Why Choose This Model

The M2000-SM combines a defined security-focused application with a compact surface-mount design. Its transformer provides five available power taps: .25, .5, 1, 2, and 4 watts. These selections give an installer multiple transformer settings within the unit’s stated operating range. The supplied product title also identifies this model as a 70V unit with a T72 transformer.

A 117-inch cable is included as part of the transducer assembly. At 3 meters long, this cable provides a clearly documented connection length for planning the installation. The product is also covered by a warranty lasting 60 months from the date of purchase.

Installation and Integration

The M2000-SM is designed for surface mounting on an office window or wall. Its physical dimensions are 2 1/2 inches by 2 1/2 inches square, with a height of 1 inch. In metric measurements, it is 63.5 mm square and 25.4 mm high. These measurements allow the required mounting area and profile to be established before installation.

System planning can account for the five transformer tap options and the 117-inch cable length. Available taps are .25 watt, .5 watt, 1 watt, 2 watts, and 4 watts. The appropriate selection will depend on the requirements of the sound masking installation. No mounting hardware, connection type, or additional included components are identified in the supplied product data.

Performance Highlights

The transducer operates by transferring a sound masking frequency to the surface on which it is mounted. This surface excitation is used to interfere with attempts to capture sensitive conversations through radio or infrared microphones positioned around office windows or walls. The product information focuses on that function rather than specifying conventional loudspeaker performance measurements.

Its documented performance-related configuration centers on the transformer taps. Five settings span from .25 watt through 4 watts, with intermediate .5-, 1-, and 2-watt selections. The supplied information does not state frequency response, sensitivity, impedance, maximum sound pressure level, or coverage measurements, so those values are not represented here.

What Makes It Different

The M2000-SM is distinguished by its direct application to a window or wall and its purpose of disrupting microphone-based eavesdropping. It is not described merely as a source of background masking sound. Instead, the masking frequency is transferred to the physical surface associated with the protected office space.

The compact square format, low 1-inch height, five transformer taps, and 3-meter cable define the model’s supplied installation characteristics. Together, these documented details differentiate it from products that require unspecified placement away from the surface or provide only a single transformer setting.

Final Assessment

The AtlasIED M2000-SM is a purpose-built surface-mount sound masking transducer for office windows and walls. Its role is to transfer a masking frequency to the surface and disrupt the use of radio or infrared microphones for overhearing sensitive conversations. The 2 1/2-inch-square enclosure, 1-inch profile, 117-inch cable, and .25- to 4-watt transformer taps provide the key specifications needed to evaluate its physical placement and integration. A 60-month warranty from the date of purchase completes the documented product information.
