Connecting speakers

Connecting speakers

Notes:

The TX-DS787 is designed to produce optimum sound quality when speakers with impedances within the specified ranges are connected. Check the following information and choose speakers with appropriate impedances for the connections.

CAUTION:

SPEAKER IMPEDANCE

6 min. per each speaker terminal.

Connecting the speaker cable

1.Strip away 15 mm (5/8 inch) of wire insulation.

2.Twist wire ends very tight.

3.Unscrew

4.Insert wire

5.Screw

When you are using only one speaker or when you wish to listen to monaural (mono) sound, a single speaker should never be connected in parallel to both the right and left- channel terminals simultaneously.

To prevent damage to circuitry, never short- circuit the positive (+) and negative (–) speaker wire.

Connecting a subwoofer

Use the PRE OUT SUBWOOFER jack to connect a subwoofer with a built-in power amplifier. If your subwoofer does not have a built-in amplifier, connect an amplifier to the PRE OUT SUBWOOFER jack and the subwoofer to the amplifier.

Be sure to connect the positive and negative cables for the speakers properly. If they are mixed up, the left and right signals will be reversed and the audio will sound unnatural.

Connect speakers with an impedance between 6 and 16 . Connecting speakers with an impedance less that 6 may damage the TX-DS787.

Do not connect more than one speaker cable to one speaker terminal. Doing so may damage the TX-DS787.
