GENERAL DESCRIPTION PS 680
The PS 680 is designed to be a six channel power
supply in an ASL intercom system and can be used
in portable as well as fixed applications.
It incorporates two adjustable auxiliary signal inputs
and uses only 1U of 19” rack space. The unit is
ideal for use in applications where standard
microphone cable is available and ease of setup is
of paramount importance.
Inside the unit are 2 switch mode power supply
modules, which are fully protected and can together
drive at least 20 Pro Series beltpacks or 10 Pro
Series speaker stations (or a combination)
operating at full power.
The Auxiliary Matrix
:
On the rear panel of the PS 680 are 2 inputs for
external audio signals, so-
called „auxiliary‟ or „AUX‟
signals. Each AUX signal may be injected to each
of the 6 intercom channels, with for each channel a
volume control for each AUX signal. With master
volume control knobs on the front panel the overall
level of each AUX signal to the intercom channels
may be adjusted. Each AUX input may be switched
to either line or mic level. When mic level is
selected, +30V phantom power is available at the
referring AUX input connector.
Fully electronic switching increases reliability and
allows for a Mic Mute and Buzzer Mute function:
By pushing the “All Mics Off‟ button on the
front panel the microphones of the stations
connected to the PS 680 are muted. At
each user station the microphone may be
switched again by pushing a TALK button.
By pushing the „All buzzers Off‟ button on
the front panel all buzzers of the stations
connected to the PS 680 are muted. To
abolish the „all buzzers off‟ status of all
these stations, this button has to be pushed
again.
Remote Mute Control:
The Mic Mute and Buzzer Mute push buttons on the
front panel of the PS 680 allow for sending these
mute signals to all channels simultaneously. In case
it is required that these signals can also be sent to
each channel separately, an external switch box is
needed which can be connected to a D-25
connector on the rear panel.

MECHANICAL INSTALLATION
A vertical rack space of 1U (1.75”/ 44,5 mm) is
required for the PS 680. It is not necessary to
provide rear support by extra bracing or shelving.
Adequate ventilation must be provided by allowing
sufficient space around the sides and rear of the
unit to ensure free circulation of air.
Forced cooling is not required.
The power supply regulator is mounted on the rear
of the unit. After a period of time it will feel hot to the
touch. This is quite normal, and should be no cause
for alarm.
