Connecting the Deck to an Amplifier (Mixer)

•

Before connecting the deck to your amplifier, please review your amplifier's instruction manual. Use the white plugs for the left channel and red plugs for the right channel.

Tape Dubbing

Many stereo amplifiers and receivers have tape dubbing circuitry so that tape duplication can be performed between two or more tape decks. Review your amplifier's instruction manual for a full explanation of this mode of operation.

Connecting Headphones

•

To listen through headphones, plug your headphones into the PHONES jack.

Installation Precautions

• If the deck is placed near an amplifier, TV or tuner, noise (induced

hum) or beat interference may result, especially during FM or AM reception. If this occurs, place the deck further away from other components or reorient its position.
