Creek OBH-18 MM Phonostage
Creek's OBH-18 Phono Pre-amp offers state of the art build quality and high-grade audiophile internal components. The OBH-18 works with most moving magnet cartridges, bringing the now-famous Creek rhythm and pacing to your system. The aluminum faceplate gives the OBH-18 a simple, timeless look, the sturdy extruded aluminum chassis minimizes vibration and protects the OBH-18 from external RFI and EMI interference.
The primary 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.
