1.0 GENERAL DESCRIPTION
The PS 10 is a single channel analog intercom
station for “Listen Only” purposes. It is often used
as an IFB Receiver. The unit is housed in a
strong metal case provided with a metal belt clip.
On the front panel are a Volume (listen level)
control and a mini jack connector to connect a
headphone or earpiece.
On the rear panel is an XLR-3 connector for the
intercom connection cable (the party line).
By applying low noise / high speed op-amps, a
propriety speech presence filter and a high power
headphone amplifier, communication is very
comfortable even in environments with a high
level of background noise.
2.0 UNPACKING
After unpacking the unit please inspect for any
physical damage and retain the shipping carton
and relevant packing materials for use should the
unit need returning.
If any damage has occurred, please notify your
dealer immediately so that a written claim can be
initiated. Please also refer to the warranty section
of this manual.
3.0 INSTALLATION
Connecting the PS 10 to an intercom system is
straightforward. The necessary DC voltages are
derived from the intercom master station or
power supply, via the intercom connection cable.
Use professional flexible microphone cable with 2
wires and 1 shield only.
Connect this cable to the LINE connector on the
rear panel of the PS 10. The unit is fully protected
against wiring mistakes (reverse power) or short
circuit in the interconnecting cables.

8.0 POSSIBLE SYSTEM CONFIGURATION
In drawing above a typical IFB (Interruptible Fold
Back) configuration:
Two PS-10’s are via two intercom party lines
connected to a PS 6379 Mk2 Master Speaker
Station, to channels E and F. These channels
can be configured as so-called IFB channels.
If one pushes a TALK button of such a channel
the AUX signal routed to that channel is dimmed
by an adjustable degree (“volume ducking”)
The (one way) intercom signal is for instance the
director talking to the host of a TV show and the
AUX signal for instance the “N-1 On Air” signal.
