10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they
exit from the device.

11. Only use attachments/accessories specified by the manufacturer.

12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the device. When a cart is used
use caution when moving the cart/device combination to avoid injury from tip-over.

13. Unplug this device during lightning storms or when unused for long periods of time.

14. Refer all servicing to qualified service personnel. Servicing is required when the device has been damaged in any way, such as
power-supply cord or plug is damaged, liquid has been spilled, or objects have fallen into the device, the device has been exposed
to rain or moisture, does not operate normally, or has been dropped.

15. WARNING: To reduce the risk of fire or electric shock, this device should not be exposed to rain or moisture and objects filled with
liquids, such as a vase, should not be placed on this device.

CAUTION – When Installing the Product

• Plugging in or unplugging the power cord with wet hands may result in electric shock.

• Never move the device with the power cord plugged into the wall, as damage to the power cord may result.

• When unplugging the cord from the wall, grasp the plug, NOT the cord.

as this may result in electric shock or fire.

• Do not place any containers with liquid or metallic objects on the top of the device.
If any liquid spills into the unit, fire or electric shock may result.

• Never operate this device or touch the power supply cord during an electrical storm, electric shock may result.

• Never exceed the wattage on the product when connecting equipment. Fire and/or property damage may result.

• Operate the device only with the voltage specified on the unit. Fire and/or electric shock may result if a higher

voltage is used.

• Do not modify, kink, or cut the power cord. Do not place the power cord in close proximity to heaters and do not
place heavy objects on the power cord, including the device itself, doing so may result in fire or electrical shock.

• Ensure that the safety ground terminal is connected to a proper ground. Never connect the ground to a gas pipe
as a catastrophic disaster may result.

• Be sure the installation of the product is stable, avoid slanted surfaces as the product may fall and cause injury or property damage.

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.
