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:
- 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.
- Turn all front panel controls to 0°.
- 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 volume 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.
LOUDNESS LEVEL
The system can now be subjectively fine tuned for effectiveness and comfort.
If the sound masking level is too high, turn the volume control knob
counterclockwise, in no more than fifteen minute increments, until the desired
loudness level is achieved. If the sound masking level is too low, turn the
volume control knob clockwise, in 10° increments, until the desired loudness
level is achieved.

If a sound level meter is available, the following spectrums are recommended:
| FREQUENCY | 100 | 125 | 160 | 200 | 250 | 315 | 400 | 500 | 630 | 800 | 1000 | 1250 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1/3 OCTAVE | 47 | 46 | 45 | 44 | 43 | 42 | 41 | 40 | 39 | 37 | 35 | 34 |
| ONE OCTAVE | 51 | 48 | 45 | 40 | ||||||||
| FREQUENCY | 1600 | 2000 | 2500 | 3150 | 4000 | 5000 | 6300 | 8000 | 1000 | |||
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | |||
| 1/3 OCTAVE | 32 | 30 | 27 | 24 | 21 | 20 | 17 | 14 | 11 | |||
| ONE OCTAVE | 35 | 26 | 19 |
OCCUPIED SPACES
If masking sound is being added to an existing space that is currently in use,
THE MASKING MUST BE INTRODUCED SLOWLY, so that it won’t call attention to
itself. Therefore, once the initial installation is complete, it will take
weeks to bring the masking sound up to its recommended level for effective
privacy. After tuning the masking as per the above procedure for unoccupied
new space, record the final settings for both the volume and equalizer
controls. Indicate on the bottom of the DS1042 unit, with a permanent marker,
the recommended settings.
INITIAL MASKING LEVEL SETTINGS FOR OCCUPIED SPACES
If you have a sound level meter, measure the existing ambient background in
several areas and record the lowest reading. Then go to the DS1042 unit and
set the volume so that the masking level is 2 dBA above the lowest ambient
reading that was recorded. If you do not have a sound level meter, set the
volume control on the DS1042 unit to the 60° position.
RAISING THE INITIAL MASKING LEVEL SETTINGS IN OCCUPIED SPACES
After a continuous Monday-to-Friday cycle of non-interrupted masking at the
initial setting, raise the masking level 2 dBA or about 10° on the volume
control from the initial setting. This increase in level must be done on
Friday at the end of the work day, after most of the employees have left the
building. Continue this weekly increase until the most desirable setting as
determined above is met. If there are objections about the masking level being
too high, as the system is being raised to its final design, re-duce the
volume by 4 dBA (or 15°) on the volume control. Leave the masking level at
this setting for two (2) weeks, and then begin to adjust the masking level
higher again as per the above technique until the acceptable level is reached.
