ASP-MG24

represents the latest technology in digital signal processing (DSP) engines for sound masking generator/

equalizers. This model features 4 built-in digital noise generators and two analog inputs speciﬁcally suited for paging
input sources. These inputs can be conﬁgured for mic or line level.

The

ASP-MG24

advances sound masking 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 a 1 RU, 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 time 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. This 6 x 4 mix matrix provides the following conﬁguration options
for sound masking systems:

1.   1, 2, 3, or 4 Channel Masking
2.   Dual Two Channel Masking
3.   Single Channel Paging
4.   Dual Channel Paging (From Single Page Input Source)
5.   1, 2, 3, or 4 Channel Mixed Paging & Masking
6.   Dual Channel Mixed Paging & Masking

Dedicated

⁄

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.

For loudspeaker control functionality, the

ASP-MG24

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 Series

ceiling speakers,

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 or RS-232 connection (no awkward USB to Serial adaptors required!).
External UL / ULC Listed international voltage power supply is included.

ASP-MG24TDB

ASP-MT24TDB

incorporates all the features of the standard model with the addition of time / date level control of

all 4 masking inputs for holiday and weekend scheduling. This powerful scheduling tool insures maximum speech
privacy in facilities that may be more or less densely occupied during various times of the day or days of the week.
Ethernet control functionality is also incorporated into this model to provide control of multiple units (up to 32) via a
standard network switch and also allows remote access and monitoring via LAN.
