Atlas Sound DSP8807 Overview

The Atlas Sound DSP8807 Self-Contained, Multi-Zone Digital Controlled Sound-Masking Processor is a self-amplified, sound-masking controller with extensive digital signal processing and telephony interface capabilities. All aspects of signal routing, processing, and prioritization are administered through an intuitive graphic user interface (GUI) managed via a local Windows-based laptop or desktop computer. The software can expand to 253 systems with over 2000 zones (2048) with primary and secondary assignment in a zone-paging dialing plan. It also provides the ability to set up an “All zone” page, a “Group zone“ page (up to 32 groups), and a “Single zone“ page with an architectural dialing plan (2-digit DTMF) set up in the GUI.

The AVB (Audio Video Bridge) audio networking allows distribution of paging, BGM, and line-level inputs between multiple DSP8807 and/or DSP2212 units across TCP/IP data networks. The DSP8807 processor features 8 channels of independent on-board digital Class-D amplifiers capable of delivering 50W RMS per 70.7V output. Additionally, a simultaneous line-level output rated at 1V/600 Ohms (nominal) per zone is available for driving higher power amplifiers.

The DSP8807 masking processor includes two independent, uncorrelated pink noise generators, which are random and non-repeating up to 215 hours with 1/3-octave EQ adjustments programmable on a per zone basis. It is capable of managing remote ambient level-sensing microphones (ALM-1) for each zone (x8) via a single CAT5E cable up to 1000’ from the DSP8807. These microphones can provide automatic adjustment of the masking level based on real-time noise levels with setup and control via the GUI.
