The Atlas Sound DSP8807 digital processor “Privacy” system is a self contained, compact multi-zone digital DSP-GUI controlled processor
and digital amplifier capable of simultaneous distribution of masking, paging, and background music signals for usemaybe in Industrial,
Institutional, Commercial and Government facilities.
The Atlas Sound DSP8807 unit is capable of automatic mixing, set up and administration of all 8x8 inputs / outputs per zone (channel)
via an intuitive ‘simple to use’ Graphic User Interface (GUI) managed via a local Windows® based laptop or desktop computer. The
DSP8807 has 8 channels of independent on-board digital class-D amplifiers that are capable of delivering 50W RMS at 70V output.
Additionally a simultaneous audio line level output rated at 1V/600
Ω
(nominal) per zone is available for driving higher power amplifiers.
The DSP8807 also has two (2) independent uncorrelated pink noise generators which are random and non-repeating up to 215
hours with EQ adjustments programmable on a per zone basis. The DSP8807 provides dynamic control and management based on
IEEE802.1 AVB standards (Audio-Video Bridging) with independent

Octave (28) band EQ *(Filter type is Butterworth @ 19dB and
Linkwitz-Riley at 24dB) and Parametric EQ for calibration of all PA, ambient level sensing and automatic level control on a per zone
basis. Paging (PA) presets can be assigned in 10dB increments (10, 20, 30dB) per zone with automatic gain control (AGC) for all Telco
and microphone paging inputs.
The DSP8807 GUI is called the ‘Sound Media Interface’. The software has the ability to expand up to (256) systems with over 2,000
zones (2,048) with primary and secondary assignment in a zone paging dialing plan. It also provides the ability to set up All zone page,
Group zone page (up to 32 groups) and Single zone page with an architectural dialing plan (2-digit DTMF) set up in the GUI. Each
DSP8807 is capable of managing remote ambient level sensing microphones (ALM-1) for each zone (x8) wired via a single CAT5e cable
up to 1,000 feet from the DSP8807 for automatic adjustment of the masking level based on real-time noise levels with set up and
control via the GUI.
Introduction
The Atlas Sound DSP8807 system provides the following basic masking capabilities:
• Creates an acceptable level of speech privacy in open work areas
• Enhances speech privacy between modular offices
• Decreases intelligibility and noise distraction caused by stand-up, casual conversations and random room noises
• Reduces awareness of existing sounds
• Increases worker productivity and employee satisfaction
• Enhances clients revenue due to less employee distraction
• Lessens the need for unexpected and expensive acoustical upgrades
• Flexibility which insures specific masking spectrums for varying ceiling types including; t-bar, open, wood slats and clouds
