Product Description

The Atlas IED ASP-MG24DB is an advanced Sound Masking Generator and Zone Controller featuring 4 built-in masking generators for 4 individual zones. The ASP-MG24TDB also features 2 additional audio inputs for mic or line sources.

This effectively provides DSP configurable audio matrixing, allowing the mic and/or line sources to be sent to any or all of the 4 output zones with priority over the masking sources. Each of the 4 masking generators adjustable ramp-up to allow gradual level increase of masking levels.

This advanced sound masking generator also features an integral scheduler card, allowing full control of each of the 4 masking generators to be timed with level control according to the changing use and noise levels of the environment throughout the day and on different days of the week.

Dedicated 1/3 octave filter sets are available for each of the 4 generator outputs, 8 band parametric EQ blocks along with dunamic 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).

For speaker 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 AtlasIED FAP ceiling speakers, SM series surface mount speakers, or AH series stadium horns for complete control of crossover types, equalization, delay and dynamic control.

The Atlas IED ASP-MG24TDB Sound Masking Generator is fully configurable via an intuitive windows-compatible set-up GUI.
