Atlas IED ASP-MG24TDB DSP Soundmasking Processor

The ASP-MG24TDB advances sound masking control including time based level control to a whole new level while providing the secondary benefit of loudspeaker processing for the most popular Atlas Sound loudspeaker systems.

The ASP-MG24 is 1RU, 6 input x 4 output DSP configurable by a very intuitive set-up GUI. Four inputs are tied to independent white/pink noise generators with adjustable ramp-up to allow gradual acclimation to masking levels. Two additional inputs are available for mic or line sources to allow paging and/or music sources to be blended with the masking sources to any of the 4 outputs.

Dedicated 1/3 octave filter sets are available for each of the 4 generator outputs, 8 band parametric EQ blocks along with dynamic control is available for each of the two mic/line inputs. Any mix of all 6 inputs may be easily matrixed to the 4 output DSP blocks for additional parametric equalization, delay, and limiting (if required).

Factoring in all features, a very complex 4 zone sound masking system can be easily configured with 2 external music or page sources. The MGTDB internal module allows timing and level control of all 4 Masking inputs for daytime holiday and weekend scheduling.

For loudspeaker control functionality, the ASP-MG24TDB may be configured in 2 input x 4 output mode for stereo full range. Other configurations include full range plus sub operation with Atlas Sound FAP ceiling speakers, SM series surface mount speakers, or AH series stadium horns for complete control of crossover types, equalization, delay, and dynamic control.

Computer interface is simplified by USB, RS-232 and Ethernet connection (no hard to use USB to Serial adaptors required!). External UL listed international voltage power supply is included.
