The AtlasIED ASP-MG2240 is a professional two-zone sound masking controller with integrated 70.7V amplification, designed to improve speech privacy and provide flexible audio control in commercial and institutional environments.
Combining digital signal processing (DSP), two independent 30-watt amplifiers, sound masking generators, and paging capabilities, the ASP-MG2240 provides a compact solution for offices, healthcare facilities, conference areas, and other spaces where confidential conversations and acoustic comfort are priorities.
The controller supports two independently configurable masking zones, allowing sound levels and masking characteristics to be adjusted for different areas within a facility.
With an estimated coverage capability of up to 7,000 square feet in a single-zone configuration or two zones of approximately 3,500 square feet each, the ASP-MG2240 offers flexibility for commercial sound masking installations.
Its included PC control software provides access to DSP settings, equalization, masking adjustments, and system presets.
Two-Zone Sound Masking with Integrated 70V Amplifiers
The AtlasIED ASP-MG2240 features two independent 30-watt amplifier channels operating at 70.7V, eliminating the need for separate amplification in appropriately sized sound masking systems.
Each zone can be configured to accommodate the acoustic characteristics and privacy requirements of its designated area.
The integrated amplification makes the ASP-MG2240 suitable for distributed sound masking speaker systems commonly installed above suspended ceilings or in other commercial spaces.
Potential applications include:
- Open-plan offices
- Private offices and conference rooms
- Medical offices and healthcare facilities
- Reception and waiting areas
- Financial institutions
- Professional service environments
- Administrative and institutional buildings
Actual coverage depends on the number of loudspeakers, selected transformer taps, ceiling construction, ambient noise levels, and acoustic design.
Advanced Sound Masking with DSP Control
The ASP-MG2240 incorporates two independent sound masking generators with adjustable equalization to help create a consistent acoustic background.
Sound masking introduces a controlled background sound that reduces the intelligibility of conversations at a distance.
This can help reduce distractions and improve conversational privacy in shared workspaces.
The controller supports white and pink noise generation, along with adjustable masking characteristics.
Its DSP-based control system allows installers to tailor masking performance to the acoustic requirements of the installation.
The included PC software provides access to masking adjustments, system parameters, and preset configurations.
Chanaud Masking Filters for Speech Privacy
The AtlasIED ASP-MG2240 incorporates Chanaud Masking Filters, designed to support effective sound masking in commercial environments.
These filtering options help installers shape the masking spectrum for the intended space.
Properly designed sound masking systems can reduce the distance over which conversations remain intelligible, improving acoustic privacy in offices and other occupied environments.
Sound masking performance depends on the complete system design, including speaker placement, sound levels, room acoustics, and commissioning.
Speech Privacy Enhancement Mode
For applications requiring additional speech privacy, the ASP-MG2240 includes a selectable Speech Privacy Enhancement function.
This mode allows the system to adjust its operation when increased conversational privacy is desired.
Visual indicators and optional privacy signage can provide occupants with confirmation that the enhanced privacy function is active.
Potential applications include:
- Medical consultation rooms
- Confidential meeting spaces
- Financial service offices
- Human resources departments
- Administrative offices
- Other environments handling sensitive conversations
In healthcare facilities, sound masking can be one component of a broader approach to protecting confidential discussions.
Note: Sound masking alone does not establish HIPAA compliance or guarantee that conversations cannot be overheard.
Integrated Paging and Background Music Inputs
In addition to sound masking, the ASP-MG2240 supports paging and auxiliary audio applications.
The controller includes a balanced microphone/line input and a 3.5mm auxiliary input for connecting compatible audio sources.
Available DSP processing includes:
- Five-band equalization
- High-pass filtering
- Low-pass filtering
- Feedback filtering for paging applications
- Output limiting
These processing features allow installers to tailor connected audio sources to the intended system requirements.
The ASP-MG2240 also includes an assignable balanced line output for integration with compatible external audio equipment.
Push Here Diagnostic (PHD) System
The ASP-MG2240 incorporates AtlasIED's Push Here Diagnostic (PHD) functionality to assist installers with system testing.
The diagnostic feature helps evaluate connected speaker lines and amplifier loading during installation and troubleshooting.
This can simplify initial system verification and help identify potential wiring or load-related problems.
The PHD feature is particularly useful in distributed 70.7V systems where multiple loudspeakers may be connected to each amplifier channel.
Compact 1RU Design for Professional Installations
The AtlasIED ASP-MG2240 features a compact chassis measuring:
- Width: 10.5 inches
- Height: 1.75 inches
- Depth: 11.25 inches
Its 1RU height allows integration into suitable equipment rack installations, with appropriate mounting hardware.
The unit operates from an external power supply accepting 110–230VAC, 50/60Hz, and uses a 24V DC input.
This compact design makes it practical for installations where equipment space is limited.
