Onkyo TX-SR8250, TX-SR502E Connecting Your Speakers, Attaching the Speaker Labels

Connecting Your Speakers—Continued

Connecting Your Speakers

Before you connect your speakers, read the following:

•Disconnect the power cord from the wall outlet.

•Read the instructions supplied with your speakers.

•Pay close attention to speaker wiring polarity. In other words, connect positive (+) terminals only to positive

(+) terminals, and negative (–) terminals only to nega- tive (–) terminals. If you get them the wrong way around, the sound will be out of phase and will sound odd.

•Only use speakers with an impedance of 6 ohms or higher. If you use speakers with a lower impedance, and use the amplifier at high volume levels for a long period of time, the built-in protection circuit may be activated.

•Unnecessarily long or very thin speaker cables may affect the sound quality and should be avoided.

•Be careful not to short the posi-

tive and negative connections. Doing so may damage the AV Receiver.

•Don’t connect more than one cable to each speaker terminal. Doing so may damage the AV Receiver.

•If you want to connect a single speaker instead of a pair, connect it to either the left or right speaker termi- nals, not both.

Attaching the Speaker Labels

The AV Receiver’s positive (+) speaker terminals are color-coded for ease of identification. (The negative (–) speaker terminals are all black.)

Speaker terminal	Color
Front left	White
Front right	Red
Center	Green
Surround left	Blue
Surround right	Gray
Surround back	Brown

The supplied speaker labels are also color-coded and you should attach them to the positive (+) side of each speaker cable in accordance with the above table. All you need to do then is to match the color of each label to the corresponding speaker terminal.

Connecting the Speaker Cables

1	Strip 5/8" (15 mm) of	5/8" (15 mm)
	insulation from the
	ends of the speaker
	cables, and twist the
	bare wires tightly, as
	shown.
2	Unscrew the terminal. Fully insert the bare
	wires. Screw the terminal tight.

The following illustration shows which speakers should be connected to which terminals.

The SUBWOOFER PRE OUT should be connected to the input on your powered subwoofer. If your subwoofer doesn’t have an amp built-in, you’ll need to use an external amp. See the manual supplied with your subwoofer for more information.
