Note

Push plugs in all the way to make good connections (loose connections can cause noise or malfunctions).

To prevent interference, keep audio cables away from power cords and speaker cables.

The integrated amplifier’s optical digital jacks have shutter-type covers that open when an optical plug is inserted and close when it’s removed. Push plugs in all the way.

To prevent shutter damage, hold the optical plug straight when inserting and removing.

Do not use digital audio signals other than PCM.

*An analog audio cable can be used instead of a coaxial cable. However, we recommend that you use a coaxial or a composite video cable.

Connecting the Power Cord

Supplied power cord

To an AC wall outlet (Plug type varies from country to country.)

Tip

To reduce noise, do not tie signal cables together with the power cable. Wire them so that they are away from each other.

Depending on the country, the integrated amplifier may be polarity-sensitive. In this case, plug the power cord in a way that provides the best sound quality.

Note

Never disconnect the power cord from the integrated amplifier while the other end is still plugged into a wall outlet. Doing so may cause an electric shock. Always disconnect the power cord from the wall outlet first, and then the integrated amplifier.

Turning on the integrated amplifier may cause a momentary power surge that might interfere with other electrical equipment on the same circuit. If this is a problem, plug the integrated amplifier into a different branch circuit.

Do not use a power cord other than the one supplied with the integrated amplifier. The supplied power cord is designed exclusively for use with the integrated amplifier and should not be used with any other equipment.
