Applications
The ASP-MG2240 is suited for applications requiring a secured speech
environment, paging or background music (BGM) audio. The
ASP-MG2240 is designed to provide detailed masking privacy for a wide
range of acoustical environments including open office areas, conference
rooms, huddle/meeting rooms, as well as delivering non-masking
content to areas where needed.
General Description
The AtlasIED ASP-MG2240 is a two zone masking controller with
integrated amplification. The compact design incorporates features
including two-channels of amplification, separate analog masking
generators with EQ, 24/7 scheduler, System Commissioning Ramp,
balanced Mic/line input, auxiliary input for background audio, and a
line output. The PC control software allows the user to customize the
system to meet the installation requirements. Settings can be stored in
the unit or in the PC for file back up or recall. The ASP-MG2240 offers
industry leading preconfigured presets that are specific to common and
advanced masking applications. These settings are based on AtlasIED
proprietary Chanaud Masking Filters.
Precise sound masking is now quick to implement. The compact
ASP-MG2240 can deliver quality audio in a single masking zone up to

7000 sq. ft. or can be spilt into two 3500 sq. ft. zones. This compact
integrated solution features two internal 20-watt amplifier channels along
with internal DSP with intuitive control software. This software makes
setup fast because of the practical real life preset configurations that can
be selected and modified for customization.
Speech Privacy Enhancement for conference rooms or medical offices
is an economical solution to meet federal HIPAA law requirements. The
ASP-MG2240 features a customizable speech privacy solution for any
environment. When in a private meeting that requires speech privacy,
a switch can be pressed to activate the "Speech Privacy Enhancement"
mode. The masking signal level will increase to a pre-set level to
enhance privacy one the button is pressed. A variety of optional Speech
Privacy Enhancement signs are available to connect to the ASP-MG2240
that provide visual indication that a room is being used and that the
speech privacy system is in use.
The ASP-MG2240 is an all-in-one solution for most environments. The
ASP-MG2240 not only supplies speech privacy but also delivers paging
and background music audio. Mic / line and AUX inputs each have a
selectable five band EQ and Hi & Lo pass filters. For paging applications,
the ASP-MG2240 incorporates a unique hi Q feedback filter specifically
tailored to the vocal frequency range. Adjustable output limiters are in
the audio chain to protect against system overdrive.
Many installations are incorrectly installed for a variety of reasons and
are a leading cause of equipment failure. The ASP-MG2240 includes a
patent pending automatic diagnostic system test, called the Push Here
Diagnostic (PHD). The PHD button is designed to check the connected
speaker lines for wiring and amplifier loading errors. This test can be
activated once all speakers are connected and the circuit automatically
verifies that the attached speakers' tap settings do not exceed the
amplifier's rated power and the speaker wire is free from shorts.
Most traditional sound masking systems require the speaker wire to
be placed in electrical conduit because of the high voltage output of
the amplifier. This method is effective but is expensive to implement.
The ASP-MG2240 meets low voltage Class 2 wiring electrical code
requirements, eliminating the need to run the speaker wire in expensive
conduit. This is a huge cost savings for any installation. The ASP-MG2240
utilizes advance technology to meet the Class 2 electrical codes but still
delivers quality speech privacy, paging, and background music audio.
The integrated amplifiers are more than 90% efficient and when
combined with a 24 / 7 masking scheduler, the system has the perfect
balance between audio performance and energy conservation. When
the scheduler is set to minimum use, the ASP-MG2240 only draws
4.4-watts, during everyday use the average power consumption is only
19-watts, and under maximum use power consumption is 67-watts. The
ASP-MG2240 is one the most energy efficient sound masking systems
available today.
