Masking System (PZA)

Amplified sound masking system with integrated DSP

The AtlasIED ASP-MG2240 is a two-zone sound masking controller with integrated amplification. This compact device incorporates many useful features including two amplification channels, separate analog masking generators with EQ, 24/7 scheduler, balanced mic/line input, auxiliary input for background audio, and line output. PC control software allows the user to customize the system to meet installation needs. Settings can be stored on the drive or on the PC for backup or recovery of files. The ASP-MG2240 offers industry-leading presets that are tailor-made for many common and advanced sound masking applications. These configurations are based on Chanaud's patented masking filters.

Now it's quick to implement precise sound masking. The compact ASP-MG2240 can deliver quality audio in a single masking zone of up to 7000 feet. ² or it can be divided into two 3500 foot zones ^{2 .} This compact, integrated solution features two internal 30-watt, 70.7V amplifier channels along with an internal DSP with intuitive control software. This software streamlines setup thanks to the reql world presets that can be selected and modified for customization.

Improving speech privacy in conference rooms or medical offices is now easy to do, allowing for compliance with federal HIPAA standards. The ASP-MG2240 features a customizable voice privacy solution for any environment. When you're in a private meeting that requires voice privacy, simply flip a switch to activate Voice Privacy Enhancement Mode. If necessary, a visual aid is needed to indicate when the room is safe for speech privacy. A variety of optional speech privacy enhancement signals are available to connect to the ASP-MG2240.

The ASP-MG2240 is an all-in-one solution that is effective in most applications. The ASP-MG2240 not only provides voice privacy, but also offers PA and background audio. The mic/line and aux inputs each have a selectable 5-band EQ and high- and low-pass filters. For PA applications, the ASP-MG2240 incorporates a unique, high-quality feedback filter designed specifically for the vocal frequency range. There are adjustable output limiters in the audio chain to protect against system overdrive.

Finally, the ASP-MG2240 includes a patent-pending self-diagnostic system test, called Push Here Diagnostic (PHD). The PHD button is designed to check connected speaker lines for wiring errors and amplifier loading. This test can be activated once all speakers are connected and the circuit automatically verifies that the bypass settings of the connected speakers do not exceed the amplifier's power rating and that the speaker wire is not shorted.
