One channel main station MS-100
Most important features of the MS-100: Main station for 19" rack mounting
1 U (44 mm). Like the main station MS-200 it operates as power supply for
up to 14 beltpacks. The model MS-100 offers a 12 V cigarette lighter which
may also serve as power supply for a mobile refrigerator or to charge a cell-
phone. Also two rack light BNC connectors are provided.

Replace
only with fuse of the same type
. In case the fuse blows again the unit has to be
sent in for repair. Voltage connector 120/240 V (

in the 240 V position. Switching to a 120 V position may damage the unit (no war-
ranty).

using standard microphone cables.
Power supply PS-100
Normally beltpacks, loudspeaker stations or signal lights receive their operating
voltage from an intercom main station. These main stations are normally intended
to be rack mounted. During the past few years a trend to the use of digital audio
mixing consoles could be observed, eliminating in many cases the so called „side
racks" since these mixing consoles also have dynamic processors on board.Sound
engineers therefore avoid additional 19" equipment. We have reacted to this trend
and developed an external power supply for small intercom components such as
beltpacks. The voltage supply is delivered by a standard microphone cable. With the
new power supply PS-100 up to 6 beltpacks may be connected.
Controls on the front side
Power switch
(
1
) – Please switch on only after connecting all other compo-
nents. Voltage selector 120/240 V (

). In Europe leave this selector in the 240 V
position otherwise the unit can be dam-
aged. Fuse holder with glass fuses, 5 x 20
mm, 200 mA slow blow (

). Only replace
with fuses of the same current. In case the
fuse blows again sent in the unit must be
return for repair.
OVERLOAD
LED (

cates that possibly too many components have been connected.
POWER
LED (

).
Controls on the rear side
On the rear side of the power supply PS-100 you will find the power cord outlet
and the two XLR intercom connectors (
5+6
). A total of 6 beltpacks may be
powered by the PS-100 (for example 3 beltpacks per output or 6 on one output).
The case of the power supply is
very rugged and made of steel
with a special coating for years
of flawless operation. Rubber
feet are provided for safe surface
mounting.

Signal light LP-100
The light dome of the LP-100 is made of white matte
glass and can be noticed even at large distances.
The LP-100 has no controls, solely an intercom
connection in-/ and output. This means that you can
position this signal light in the intercom chain wher-
ever you want and where it is needed. The operation
voltage is carried by the microphone cable.
