OBH 18
Phono pre-amplifier
Phono pre-
With modern amplifiers expected to cater for so many new devices, the phono capability has
frequently been one of the features to disappear. At Creek Audio, the engineering team has
always been aware of the benefits of vinyl – that is why the company continues to provide a
number of phono stage options.
An exceptionally popular part of the range has been the OBH 18.
The function of the OBH 18 is to boost the level and correct the frequency response of a low
level signal coming from a moving magnet 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.
The OBH 18 looks the part too! Designed to complement the Creek range of amplifiers, tuners
and CD players, it features an impressive solid aluminium front panel in a silver finish. The
remainder of the 150mm casing is black so the product all but disappears.
