More details on the AtlasIED Sound Masking Bundle
System Overview: The Atlas SM2Z Sound Masking bundle includes an Atlas MG2240 sound masking controller/amplifier, six M1000 8" sound masking speakers, six MCHAIN72 72" speaker suspension chains, and a 500' spool of Liberty 18AWG, 2-conductor speaker wire that's rated for commercial use in plenum air spaces.
Amplifier Overview: The Atlas MG2240 is a 2-zone sound masking system that can provide high quality speech privacy as well as background music and paging. The MG2240 includes a multitude of features enabling it to conform to most design requirements, while remaining intuitive enough for simple operation. Designed for 70V use, the MG2240 can provide up to 7,000 sq. ft. of sound masking coverage for a single zone, or 3500 sq. ft. of sound masking for 2 separate zones, making it ideal for businesses, conference rooms, and office spaces. In addition to sound masking, the MG2240 can also provide paging and background music (BGM), with a 3.5mm stereo summed input, as well as a 3-pin Euroblock (Phoenix) audio/paging input that can accept either Line or Mic signals.
2-Zone: The Atlas MG2240 can provide up to 60W of power to 2 zones (30W per zone) for 70 volt commercial speaker systems. Low impedance speakers (8Ω) are not supported. Each Zone features its own integrated analog noise generator using proprietary Chanaud masking filters, with user-selectable Pink or White Noise. Each Zone can be independently configured and controlled. Two rear-panel Phoenix connectors provide the powered outputs - Amp A and Amp B.
Speech Privacy Enhancement: The MG2240 features a Speech Privacy Enhancement mode that can be engaged while a meeting is in progress. This mode applies additional acoustical energy to the surrounding environment, increasing the privacy for the room occupants. Atlas' unique secured speech filters have been approved and implemented in many installations around the world including military and government facilities, and meets federal HIPAA law requirements. Activation of the Speech Privacy Enhancement feature can be done using a hardwired contact switch (not included) attached to the rear-panel 3-pin Privacy Enhancement connector. A rear-panel connector port can supply +10VDC/100mA to power an optional LED sign that can be a visual aid to notify attendees when Enhanced Privacy Mode is active. When engaged, the front panel LED will light and the masking level will change to the user pre-set level.
BGM & Paging: In addition to exceptional sound masking, the MG2240 can deliver high quality background music (BGM) and paging as well. The Mic/Line and 3.5mm Aux inputs each have 5-band EQ along with high- and low-pass filters for maximum performance. For paging applications, the MG2240 uses a unique high-Q feedback filter that's specifically tailored to the vocal frequency range, as well as output limiters to protect against system overdrive.
24/7 Scheduler: This feature can incrementally increase the sound masking level through the work day; starting off low in the morning when less masking is needed and increasing as the ambient noise level increases throughout the day.
System Commissioning Ramp (SCR): Each zone can have its own independent System Commissioning Ramp that will gradually increase the sound masking level by 1dB each day over a 14 day period. This is a useful way for people to get acclimated to the sound masking over several days.
Push Here Diagnostic (PHD): The MG2240 sound masking amp includes a patent pending automatic system test to check the connected speaker lines for wiring and impedance errors. Two front panel Push Here Diagnostic (PHD) buttons, one each for Ch. A and Ch. B, can automatically verify that the attached speakers' tap settings do not exceed the amplifier's rated power, that no speakers are mistakenly tapped at 8Ω, and the speaker wire is not shorted anywhere.
Configuration & Presets: Configuration of the MG2240 is done via a connected PC computer running Windows 7 or newer, 32- or 64-bit (MAC not supported). A USB flash drive is included containing the configuration software. Once loaded onto your computer, the computer can be plugged into the sound masking amp's front panel micro-USB port, letting you customize settings as well as store/load user-configurable Presets (Projects), both to the MG2240's internal memory and to your computer. Four factory Presets are available: Open Ceiling, Above Ceiling, Below Floor, and Factory, along with 6 user-definable Presets. Some of the key on-screen (GUI) configuration options include: Independent level controls for the Mic/Line, Aux, Masking Outputs (Amp A & B), Master Output Level, and the Line Output Level. This also includes individual levels for Privacy Level and options to Mute each channel.
