Connecting the record player

Insert the output lead of the power supply into the recep- tacle (14) at the rear panel of the TD 550. By means of the supplied power cord connect the IEC input at power sup- ply with mains wall outlet.

ATTENTION: Never try to feed 230V mains voltage into the receptacle (14), as this will definitely de- stroy the electronic circuitry inside.

Press Power button (1) whereupon the blue-illuminated Thorens-logo (3) in the centre of the front panel and one of the speed-LEDs will light up.

The brightness of the Thorens-logo and LEDs can be changed at the dimmer potentiometer dubbed Am- bience (12) at the rear panel with the help of a small bladed screwdriver (trimmer).

Proceed by inserting the supplied RCA interconnects (or any other suitable RCA/XLR interconnects of your choice) into the signal output jacks at the rear panel.

Connect the leads with the phono input at your amplifier. The TD 550 features balanced XLR-connectors (9+10) as well as unbalanced RCA-connectors (6+7).

Note: nearly all vinyl records have been recorded ac- cording to the international RIAA standards and rules. For this reason they need a dedicated phono amplifier stage which is to equalize and amplify the usually low- level signals coming from the pickup cartridge. If the TD 550 is directly connected to a high-level input of the amplifier, the result will be a weak and distorted rendi- tion of the music.

If you happen to own a preamplifier/amplifier with integrat- ed phono stage which also features balanced (XLR) inputs, you should in any case use this high-grade connector for sonic reasons. In case your amplifier is not equipped with a phono stage or with one of rather mediocre quality, we can highly recommend to acquire the Thorens TEP 302.

Take the dustcover and carefully insert it into the hinges by the marked areas.
