Creek Audio has always been a fan of the vinyl disc. For those consumers who have an interest in enjoying this alternative source of high quality music, there are few amplifiers equipped to deal with this as standard. The Creek EVOLTION is designed to accept a plug-in Phono module to enable vinyl reproduction. The module must be fitted inside the amp, in place of the Auxiliary Line input.
The EVOLUTION amplifier is supplied as standard with a bridging link inside that connects the input sockets through to the pre-amp in the same way as its other LINE level inputs. However, when the link is removed, a Moving Magnet or Moving Coil pre-amp can be plugged-in allowing the first input (Disc) to be used to amplify a signal from a turntable.
The circuitry cannot be switched for MM or MC so the correct module must be chosen to match the cartridge fitted on the turntable. The EVOLUTION amp’s display will automatically show Disc, when the amp is fitted with the Plug-in module and selected for that input.
The discrete circuitry used on the Plug-In module is similar to that used in the stand alone Phono pre-amps OBH-15 and OBH-18.
