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. 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.
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.
