The OBH-18 was released in late 2003. 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 OBH-18 is designed to boost the signal and introduce an R.I.A.A. frequency response characteristic.

Overview

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.

The OBH-18 looks the part too! Designed to complement the Creek range of amplifiers, tuners and CD players, the new OBH range features an impressive solid aluminium front panel in a silver finish. The remainder of the 150mm casing is black so the products all but disappear.
