Thank you for purchasing the OBH 18 phono pre-amplifier. You are
now in possession of a state-of-the-art product. The functions and
operation of the OBH 18 are extremely simple. The following notes
are provided to explain all aspects of its design and use.
The function of the OBH 18 is to boost the level and correct the
frequency response of a low level signal coming from a phono pick-
up on a conventional turntable.
The signal required by most modern amplifiers is described as
being 'LINE' level, which is, in technical terms, between 200 and
500 milli Volts with a flat frequency response.
Unless your amplifier has a specific 'Phono' or Disc input, the level
will be too low and the frequency response will be wrong. The
OBH 18 is designed to boost the signal and introduce an R.I.A.A.
frequency response characteristic.
