USER MANUAL MM FLEX THORENS
Congratulations and thank you for purchasing the MM Flex MM phono preamplifier. Please read this manual carefully before operating your unit in order to guarantee the best performance.
The Thorens MM Flex is a high performance moving magnet phono preamplifier that can be fitted directly to the rear of your turntable by means of the unique Velcro™ strip. This allows it to be assembled to your turntable without any irreversible modification. Also, thanks to this system, the MM Flex can be removed and re-fitted without the use of tools.
Your local Thorens dealer or distribution partner will be pleased to assist if you have any further queries or need more information about this product:

Installation and Operation
Assembly
Identify a space on your turntable where you wish to fit the MM Flex and make sure it is dry and free from grease, dirt, dust and fingerprints. This should not be close to the motor or any other source of magnetic field. Peel off the protective film on the Velcro™ strip on the rear of the MM Flex, then, taking care not to touch the adhesive, fix the entire unit to the turntable in the desired position and apply pressure for 20-30 seconds.
Connection and Operation
Please read the following instructions carefully and carry them out in the order shown.
1. Connect your turntable to the MM Flex
Plug the leads from your turntable's cartridge to the input sockets on the MM Flex; the Right channel (red) cable into the Right input and the Left channel (white) into the Left input. If your tonearm has a separate earth wire for shielding purposes, please connect it to the earth binding post on the MM Flex.
Your amplifier should be powered off or muted and The MM Flex's power supply should not yet be connected.
2. Connect the MM Flex to your amplifier
Connect good quality RCA interconnect cables from the MM Flex to an auxiliary line-level input on your amplifier (Aux, Tape in, CD, Tuner, etc.).
Please ensure that the right channel output is connected to the right channel input on your amplifier, and the left channel output is connected to the left channel input on your amplifier.
If your amplifier is already equipped with a phono stage, do not connect the output of the MM Flex to the phono input: this is meant to be connected only to a turntable's cartridge output, not to a line level output such as that of the MM Flex.
Installation and Operation
3. Connect the power adaptor
Make sure the power switch is in the OFF (outwards) position and the power adaptor is not connected to a mains socket.
Connect the Thorens power supply plug to the power socket on the rear panel.
After choosing and installing the correct snap-in mains plug for your country, connect the power adaptor to a live mains socket then press the power button on the rear panel to the ON (inwards) position.
Always use the supplied mains power adaptor or an original Thorens spare part!
If you prefer, the MM Flex can be left powered on thanks to its tiny power consumption. If you plan to leave it unused for a prolonged period of time, we suggest disconnecting the power adaptor from the mains socket.
Your MM Flex is now ready for use. Switch on or un-mute your amplifier and enjoy your favourite music!
