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.
