Introduction

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/600Ω (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
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.

70V SPEAKER TERMINATION

Dockable 2-pin/socket connectors (commonly referred to as ‘Phoenix’ type) are used which are keyed or polarized to fit one way – do

not force fit these connectors and follow these basic instructions;

• Do NOT force fit the connectors – they are polarized to fit in one direction

• Follow the +/- wiring polarity to all speakers

• Use only 70V speakers

• Ensure that total speaker wattage taps per channel does NOT EXCEED 80% of the rated output of 50W RMS per zone.

AC POWER INPUT (120VAC @ 60Hz or 240VAC @ 50Hz)

As noted in the ‘important notices’ section the DSP8807 utilizes a UL recognized IEC AC power plug and cord (provided with the unit)

which must not be changed or defeated. Please follow these important instructions. Failure to do so will void the product warranties.

The Mains Plug is the main disconnect device for the product, and shall be located so as to be readily accessible.

NOTE: Once the AC power is switched ‘ON’ it will take approximately ‘30’ seconds to initialize and start up.

• Do not defeat the safety purpose of polarized, keyed or grounding type connectors. A polarized plug has two (or multiple) contacts

with one wider or longer than the other. A grounding type plug has two blades and a third grounding plug. The wide blade or third

prongs are provided for your safety. Do not defeat or change these. If the provided IEC power plug does not fit into your outlet,

consult an electrician or your local authority having jurisdiction to replace the outlet to ensure meeting local building codes while

assuring proper connection.

• Protect the power cord from being walked on or pinched particularly at the plug, receptacle outlet, and the exit point of the unit.

settings for zones 1 through 8.

Setting example: If you select 57dB, 63dB and 69dB the masking noise level will raise 1dB as each ambient level is

reached this will occur as each level is passed for a total of 3dB masking noise increase as the ambient level passes

69dB. The reverse will occur as the ambient level decreases past the selected ‘trip points’ so that the masking noise

level returns to the base level setting.

PAGE PLANS

1. In setting up the DSP8807 ‘Page Plan’ select the ‘PAGE PLANS’ button. This will drop down the ‘Page Plans’ box. Select which

‘Local Zones’ 1 through 8 (specific to each DSP8807 unit being programmed) are to receive Telco, Mic/Line 1, or Line 2 source

inputs to be broadcast into these zones. Repeat this step relative to the ‘Network Zones’ to be sent these broadcast pages or

sources. The Telco ‘Page Plan’ zones are 2-digit DTMF codes ranging from ‘00’ to ‘99’. The ’Page Plan’ consists of 100 Telco dial

plans from 00 to 99 and one (1) for Line1 and Line2 and Microphone. NOTE: The switch ‘dry’ contact closures or the rear panel are

used to select the Line 1, Line 2 and Mic page plans.

Digital Processor

2. Each Page Plan has ‘Local’ and ‘Network‘ zones. Page input sources will route to those which are selected.

For multiple DSP8807 units; when any unit, executes a page it will broadcast to all other units connected on the network. The ‘Network

Zone’ button within the ‘Page Plan’ when selected will route the page output to the selected ‘Network Zone’ outputs

EXAMPLE: There are two units networked together, one on each floor of an office building with (8) zones per floor. There is a

requirement for an ‘All Page’ to (16) zones from the ‘Mic’ input. To do this you set the ‘Mic Page’ plan to output to all local zones and

all network zones.

selected to view status of microphone operation as a ‘signal present’ voltage (milliamps) to indicate DSP8807 is receiving input

signal. There are two independent meters: Left meter reads every (2) seconds averaged over one (1) minute the Right meter is the

real time dB level based on settings made in the ‘Noise Trim’ option.

TROUBLESHOOTING GUIDE

1. Read and review all sections and follow instructions in this manual.

2. Before terminating speakers to ‘Speaker Output (70V)’ Zone 1 to 8, verify that all wiring is free from shorts, opens, crosses, ground

problems or loose or frayed wiring. Ensure wiring follows the correct polarity (+ / -).

3. Ensure AC power is correctly terminated with the IEC power cord provided. If after power is activated and system input and output

terminations are verified and no audio is detected, ensure all volume and activation settings have been properly set and applied in the

operating GUI/Sound Media Interface per instructions. Ensure that all speakers are connected to the DSP8807.

4. If you continue to experience difficulty please contact Atlas Sound Customer Service department by telephone at 1-800-876-333,

online at www.AtlasSound.com, or by email at [e-mail].
