ONKYO TX-SR578 Manual Do Utilizador

En

The following table indicates the channels you should use 
depending on the number of speakers that you have. 
For 7.1-channel surround-sound playback, you need seven 
speakers and a powered subwoofer.

*1

If you’re using only one surround back speaker, connect it to 
the SURR BACK OR FRONT HIGH L terminals. 

*2

Front high and surround back speakers cannot be used at the 
same time.

No matter how many speakers you use, a powered sub-
woofer is recommended for a really powerful and solid 
bass.
To get the best from your surround sound system, you 
need to set the speaker settings. You can do this automati-
cally (

23) or manually (

36).

The AV receiver’s positive (+) speaker terminals are all 
red (the negative (–) speaker terminals are all black).

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

Read the following before connecting your speakers:
• (North American and Taiwan models) You can con-

nect speakers with an impedance of between 6 and 16 
ohms. 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 amp protection circuit may be acti-
vated.

• (European, Australian and Asian models) You can 

connect speakers with an impedance of between 4 and 
16 ohms. If the impedance of any of the connected 
speakers is 4 ohms or more, but less than 6 ohms, be sure 
to set the minimum speaker impedance to “4ohms” 
(

36). 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.

• Disconnect the power cord from the wall outlet before 

making any connections.

• 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 negative (–) 
terminals. If you get them the wrong way around, the 
sound will be out of phase and will sound unnatural.

• Unnecessarily long, or very thin speaker cables may 

affect the sound quality and should be avoided.

• Be careful not to short the positive and negative wires. 

Doing so may damage the AV receiver.

• Make sure the metal core of the wire does not have con-

tact with the AV receiver’s rear panel. Doing so may 
damage the AV receiver.
