Memphis MC 1
Discrete Solid State Moving Coil Phono Stage
The new phono stage Memphis MC 1 is a discrete no-(global)feedback concept with BJTs only in the direct signal
path. It comprises one single gain stage only to amplify the MC signal above line level. It is followed by a passive RIAA
equalization and a subsequent emitter follower at the output (fig. 1). A step-up transformer elevates the MC signal
close to MM level. The first stage is designed as a high gain transconductance amplifier. It injects the amplified audio
signal current into the RIAA network as a frequency dependent load. The voltage across the load drops with
ascending frequency according to the RIAA equalization curve.
