Creek OBH-22
Thank you for purchasing the OBH-22 Infra-red remote control passive Pre-Amp.
You are now in possession of a State of the Art product. The functions and operation
of the OBH-22 are extremely simple. However, the following notes are provided to
explain all aspects of its design and use.
OVERVIEW
The function of the OBH-22 is to provide input selection
and volume adjustment to your Hi-Fi system from your
armchair, via infra-red remote control. The unit consists
of a high quality motorised volume potentiometer, and
two stereo relays which select the desired input and tape
output, together with a muting relay that can short the
signals to ground. A built-in micro-controller decodes the
infra-red signals transmitted by the handset and
translates them into commands which activate the
motorised potentiometer and the muting and input
selection relays.
controller turns itself off to avoid any possibility of
interfering with the main music signal. LED's are used to
indicate the status and mode of operation.

any gain or distortion into the signal path. It is therefore
suitable to be used as a control Pre-Amp, provided the
sensitivity of the power amp that is being used is high
enough to be driven directly from the source. i.e. CD or
Tuner etc.

not, but without power only Line 1 can be utilised.
