APPLICATION
The 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 generator and two analog
input specifically suited for use as a paging input. 6x4 mix matrices are
provided to allow operation in the following configurations:
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
The ASP-MG24 offers a variety of user selectable filter options
including one-third octave, parametric high/low pass, and high/low
shelving filters. All set-up and operating functions of the ASP-MG24
are conducted from a PC using software provided for Windows XP.
After defining and downloading the control functions through the PC,
the settings will be stored within the unit in non-volatile memory (no
battery required). The ASP-MG24 model features 16 program setups.

ARCHITECT AND ENGINEER
SPECIFICATIONS
The Atlas Sound ASP-MG24 shall be a 1RU
DSP 40 bit 96 KHz 2x4 signal processor with
internal masking generators. The ASP-MG24
shall provide two balanced audio Mic/Line-level
inputs along with four independent internal digital
white/pink noise generators inputs. The mic/
line inputs shall provide 30dB of gain. Each
of the Mic/Line inputs shall have independent
gain control, parametric filter, compressor limiter
and mute function. All inputs and outputs shall
be provided on plug-in Euro / Phoenix type
dockable connectors. The four independent
assignable white/pink noise generators shall
have a spectral purity of ±0.1dB from 0Hz to 20
kHz, precision low-pass filtering of +/-3dB per
octave, and an extended “non-apparent” repeat
time of 200 minutes. The DSP processor shall
provide four independent output channels with
gain management, parametric equalization, delay,
limiting, mute and mixing matrix. The ASP-MG24
shall have four differentially balanced outputs.
Equalization shall be combined 1/3 octave
& parametric, fixed high/low shelving filters,
and variable high pass-low pass filters. Delay
time shall be adjustable for each output, with
automatic distance/delay calculation (at STP.)
The masking generators shall provide power
failure programmable ramp function. The ASPMG24 shall include an internal socket for an
optional advanced masking scheduler card. The
ASP-MG24 software shall provide an intuitive
GUI interface with level metering capability.
All processor controls shall be provided via
software graphic interface. Sixteen nonvolatile
memory presets shall be available to store/recall
processor settings. Serial ports shall allow RS232 or USB control, with Windows
software. The ASP-MG24 shall provide front
panel LED monitoring of input and output levels.
Optional remote control is available. Frequency
Response shall be +0/-0.5dB (20Hz-20kHz
@ +4dBu). THD+N shall be less than 0.002%
(20Hz-20kHz @ +4dBu). Dynamic Range shall
be greater than 100dB (20Hz-20kHz @ unity
gain). Power Consumption shall be less than 21
watts. Dimensions shall be 1.75” high, 19” wide,
& 8” deep. Weight shall be 13.2 lbs. Warranty
coverage shall be 1-year. The noise masking
processor shall be CE marked, include a ULC/UL
Listed power source. The processor shall be an
Atlas Sound ASP-MG24.
