Thank you for purchasing the OBH-10 Infra-red remote control module. You are now in
possession of a State of the Art product. The functions and operation of the OBH-10
are extremely simple. However, the following notes are provided to explain all aspects
of its design and use.
OVERVIEW
The function of the OBH-10 is to provide volume adjust-
ment to your Hi-Fi system from your armchair, via infra-
red remote control.
The unit consists of a passive volume potentiometer,
with a motor connected to its control shaft and a two
channel relay that can short the signal path to ground to
mute it. A microprocessor control circuit can decode
infra-red signals transmitted by a separate handset and
translate them into commands that will activate the
motorised potentiometer and muting relay.
The OBH-10 is purely passive and does not introduce
any gain or distortion into the signal path. It is therefore
suitable to be inserted into the signal path of any piece
of audio visual equipment with a suitable signal level.
MAINS CONNECTION
When unpacking the module please keep the packing
material in a safe place for possible future use.
