OBH-15 MK2 MM/MC

The OBH-15 mk2 has a completely new circuit design, with a discrete transistor MC and integrated circuit MM stage. Unlike its predecessor, the new amp has multiple gain settings and matching capabilities for capacitance and resistance. The signal required by most modern amplifiers is described as being ‘LINE’ level which is, in technical terms, between 200 and 500 milli-Volts sensitivity with a flat frequency response.
