INSTALLATION GUIDE

DYNASOUND PRO DS1042

SOUND MASKING SYSTEM

UNPACKING

The unit was carefully checked before leaving the factory. Inspect both the unit and its shipping container

for indication of improper handling. Report any equipment damage to the distributor immediately. If the

unit was shipped to you, notify the shipping carrier without delay and place your claim. Unpack the unit.

It is ready to be installed.

NOTE:

When a control knob is set to OFF, it is at the 0° setting. To adjust the volume or equalizer con-

trol, you can move the knob either clockwise or counter-clockwise within a range of 0° to 359°. Using a

clock as an example, the 90° setting is at 9:00 o'clock, 180° at 12:00 o'clock, and so forth. If you turn the

knob from the 180° position to the 135° position (halfway between 90° and 180°), you have moved the

knob 45° counterclockwise.

DESCRIPTION

This model contains a digital masking generator, low pass filter, 25 watt amplifier, volume control, and an

equalizer control. The 70 Volt outputs consist of two phono plugs and one terminal strip.

INSTALLATION

As with any power amplifier, this unit requires proper ventilation for safe use as well as its own long-term

reliability. The DS1042 requires a free flow of cooling air on all sides as well as the top and bottom. Never

place articles such as books, etc. on top of the unit or against its sides. Never operate the unit on a soft sur-

face such as carpeting, etc. that may affect airflow on the bottom of the unit. Never operate the unit near a

heat vent or other heat-generating devices. The power amplifier relies upon its ability to get cool air.

CONNECTING & USING THE MASKING GENERATOR/AMPLIFIER:

1. Connect a 25 watt (or less) load to one terminal strip. 70 Volt output. The 70 Volt outputs consist

of two phono plugs. When you connect any masking devices to the phono plug and/or terminal

block, make sure that the load does not exceed 25 watts.

2. Turn all front panel controls to 0°.

3. Plug the DS1042 power cord into the outlet. Turn the Volume control (left control) clockwise until

you hear the masking sound coming from the first masking device. (The setting will be at about

135° on the dial.) It should be set very low so you can just hear it. The purpose of this is to make

sure that each masking device is operational.

EQUALIZATION

Set the volume control on the DS1042 unit to 90° and the equalizer (low pass filter) control to 0° (off po-

sition). Check all speakers to make sure that they are connected and operating properly. Make sure that all

ceiling panels that have been removed are put back in place if the installation includes plenum speakers.

FOR NEW SPACES

For 9 foot high, 1/2" to 3/4" thick mineral fiber ceilings with ceiling plenums that are reflective (no spray-

on or batt insulation), set the volume control indicator to the 85° position on the dial and the equalizer

control to the 120° position. For 1" foil-backed glass fiber ceilings with conditions as above, set the vol-

ume control indicator at the 75° position on the dial and the equalizer control to the 165° position.

If these design characteristics do not apply, contact Biamp for tuning assistance.
