Bose EdgeMax™ Observation Room Sound System

This Bose observation room sound system comes with 2 Bose EdgeMax™ EM90 in-ceiling premium loudspeakers with proprietary Bose PhaseGuide® technology to create room-filling coverage patterns typical of larger surface-mount speakers with the architect-preferred aesthetics of in-ceiling models. This system is perfect for rooms where installing speakers in the middle of the room is not an option. This sound system provides a simple solution to remotely listen, record and talk back (optional) from a central location. An omnidirectional boundary microphone can be placed in the ceiling, or on a large surface such as a table, floor, or wall, allowing a wide, smooth and very intelligible audio quality. The microphone feed can connect to a single or central observation room. As the observer watches and listens to the case room, the audio can be routed to a recording device such as a computer or digital recorder. The small microphone size and low profile provide an excellent option for listening and recording observation rooms and discrete applications.

For maximum coverage, the unique Bose EdgeMax™ speakers should be spaced approximately 30 feet apart
and are ideal for ceilings up to 14 feet.

Bose EdgeMax™ EM90 Premium In-Ceiling Loudspeakers

The Bose EdgeMax™ EM90 in-ceiling premium loudspeakers feature proprietary Bose PhaseGuide® technology to create a category that combines the room-filling coverage patterns typical of larger surface-mount speakers with the architect-preferred aesthetics of in-ceiling models. Designed to mount near wall-ceiling boundaries, EdgeMax™ loudspeakers provide improved audio quality and coverage, while reducing the number of required units. Bose Professional EdgeMax™ Premium In-Ceiling Speakers are ideal for applications such as retail stores, restaurants, hospitality venues, hotels, offices, meeting rooms and architectural custom sound design applications. They feature magnetically attached white grilles for quick access to wiring, and 8Ω or 70/100V transformer tap settings, as well as auto-hold, spring-loaded mounting arms for fast and easy installations, and they ship with an accompanying tile bridge. They are UL1480 listed for air-handling plenum space code requirements.

AKG PZM10 Boundary Layer Microphone

The AKG PZM10 is part of the Pressure Zone Microphone line, and is designed for security, surveillance, and conference-table use. Since it does not look like microphones, it is inconspicuous. Each mic’s tubular housing mounts in a 25/32-inch diameter hole in a ceiling panel, wall or table. The PZM-10 has a mic level output and a 3-pin XLR-type connector for easy plug-in installation. The mic requires 12 to 48V phantom power. It requires 12 to 24VDC. Like other Pressure Zone Microphones, the PZM-10 uses a miniature mic capsule mounted very near a sound-reflecting plate or boundary, in the Pressure Zone. In this zone, direct sound from the sound source combines in phase at all frequencies with reflected sound off the boundary. The benefits are many: 6 dB more sensitivity, 6 dB less noise, a wide smooth frequency response free of phase interference, excellent clarity and “reach,” and consistent pickup anywhere around the mic. Frequencies below the voice range are rolled off to reduce pickup of air conditioning rumble. The high-frequency response is boosted slightly to help articulation. Because of their tailored response and PZM construction, the PZM-10 will pick up conversations or other desired sounds with extra clarity and definition. The output is balanced, low impedance, which allows long cable runs without hum pickup or high-frequency loss. The mic’s humbucking transformer and steel case prevent hum pickup, even near fluorescent lights.
