Installation and Operation

Connect your turntable to the MM 002
Plug the leads from your turntable’s cartridge to the in-put sockets on the back of the MM 002: the Right chan-nel (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 rear panel of the MM 002.

Your amplifier should be powered off or muted and the MM 002’s power supply should not yet be con-nected.

Connect the MM 002 to your amplifier
Use high-quality RCA interconnect cables to connect the MM 002 to an auxiliary line-level input on your ampli-fier (Aux, Tape in, CD, Tuner, etc.). Please ensure that the right channel output is connect-ed 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 and you are upgrading your system with the MM 002, do not connect the output of the MM 002 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 002.

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 cable 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 002 can be left powered on thanks to its very low power consumption levels. If you plan to leave it unused for a prolonged period of time, we suggest disconnecting the power adaptor from the mains socket. The MM 002 is now ready for use. Switch on or un-mute your amplifier and enjoy your favourite music!
