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.
WEIGHT
Creek Audio Ltd reserves the right to change or modify
the specification of its products without prior warning.
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.
Designed and made in the UK.
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. After each operation,
the micro-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.
Handset
The OBH-22 is purely passive and does not introduce
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.
