Description
The Dynasound DS1092 incorporates a masking generator, music and paging mixer, and a power amplifier.
The masking generator is an analog type for true Gaussian noise, and includes a pink / white switch and
variable low-pass filter which is adjustable over a range of 800 to 8,000 Hz. The mixer includes a transformer-
isolated telephone paging interface as well as electronically balanced low-Z mic input and line level input for
use with a tuner, CD player, tape, etc. The mixer also contains bass and treble control as well as power on and
signal presence indicators. A master volume control adjusts the overall level. The power amplifier will produce
40-Watts.
Installation
A. Ventilation
As with any power amplifier, this unit requires proper ventilation for safe use as well as its own long-term
reliability. The DS1092 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
surface such as carpeting, etc. that may effect 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.
B. Connecting & using the masking generator
1.
Connect a 40 Watt (or less) load to the 70 Volt output or an 8 ohm load (or greater) to the 8 ohm
output. Only one output may be used at a time. Don’t attempt to use the 70 Volt and 8 ohm outputs
simultaneously.
2. Turn all front panel controls to “0”.
3.
Connect the DS1092 to a nominal 120 Volt 50-60 Hz source.
4. The green power LED should now be lit.
5. Set the Pink / White switch to the desired position.
6.
Set the Low Pass and Masking controls to 3 and adjust volume to approximately 47 dBA, generally
around 5.
7. Gradually increase the Volume control. The yellow Signal LED should come on at between 2 and 4 on
the volume control setting.
