THORENS MM-FLEX

The Thorens MM-Flex phono preamp is a high-quality preamplifier with portability in mind. Attach it to any surface with the included velcro adhesive—and better yet, due to its size you can take it with you! The Thorens MM-Flex is ideal for the on the go audiofile who may find themselves in a warehouse, surrounded by a particularly large sound system...for whatever reason.

MM-FLEX FEATURES
  • Compact MM phono preamplifier
  • Attaches to rear of turntable with integrated Velcro strip
  • Can be easily removed and re-fitted without irreversible modification

The Fono MC is an exceptionally high quality MC phono stage designed to maximise the potential of any MC cartridge. Although specifically to compliment the latest Rega range of  moving coils you will find full adjustability for loading is available via dip switches conveniently placed on the rear panel with two different gain settings located on the back panel making the Fono MC compatible with most low output MC cartridges.

The Fono MC has been designed to be effective, easy to use, and above all, to reproduce music. The Fono MC uses the Linear Systems low noise LSK389 FET in an all discrete input stage where low noise and linearity are vitally important to get the best from an MC cartridge. Because of the high input impedance of FET, the loading effects of the amplifier circuit are minuscule and do not affect the performance of the cartridge.

A MUSE operational amplifier is used in the RIAA equalization amplifier. Polypropylene capacitors have been used in the signal path and in the RIAA equalization circuits. There is selectable input loading for both resistance and capacitance along with two different gain settings located on the back panel making the Fono MC compatible with most low output MC cartridges.

The aesthetic design of the Fono MC was as important as the quality of its electrical capabilities, so it benefits from the same aluminium case as the Rega TTPSU and Fono MM amplifier, giving it a design which offers a familiar feel and moreover brings it in line with its illustrious bigger brothers. The new Fono MC circuit resulted from the design work carried out on the Aria phono amplifier.

The Fono disk stage is designed to amplify the signal from a moving coil cartridge to a level which can feed into a 200mV line level input on a standard hi-fi amplifier.

Both Microsoft® Windows® and Apple® Mac OS® come with very simple audio recording software pre-installed. However, to take full advantage of the high-resolution recording facilities offered by the MM 008 ADC, we recommend recording software that can record at 24 bits/96 kHz and save lossless high-resolution audio files such as FLAC or Apple® Lossless.
