About the DS1404
The DS1404 is a four channel, PC programmable, line-level attenuator used primarily to control soundmasking
levels based on date and time-of-day. The DS1404 can also be used to provide attenuation schedules for
background music or paging signals. Highly configurable custom schedules can be created and downloaded to
the DS1404 using the provided Windows based software.
The front of the unit provides buttons used for minor changes, such as adjusting the time of day. The front panel
buttons are also used to toggle the display between channels 1-2 and 3-4. The rear panel provides line level input
and output connections via industry standard Phoenix™ connectors, a com port for PC connections and bypass
controls.
