Creek OBH 15
Phono Pre-Amplifier

Instructions
Thank you for purchasing the OBH 15 phono
The function of the OBH 15 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 15 is designed to boost the signal and introduce an R.I.A.A. frequency response characteristic.
