Connection - Onkyo TX-SR503E Instruction Manual

Connecting Your Speakers
Speaker Configuration
For the best surround-sound experience, you should con-
nect seven speakers and a powered subwoofer.
The following table shows which channels you should
use based on the number of speakers that you have.
Number of speakers:
Front left
Front right
Center
Surround left
Surround right
Surround back*
Surround back left
Surround back right
*If you're using only one surround back speaker, connect it to
the left (L) SURROUND BACK SPEAKERS terminals.
No matter how many speakers you use, a powered sub-
woofer is recommended for a really powerful and solid
bass.
Before using the AV receiver, you must specify which
speakers are connected and their sizes (see page 32).
To get the very best from your surround-sound system,
you should also specify the distance between the listener
and each individual speaker so that the sound from each
speaker arrives at the listener's ears at the same time (see
page 50). In addition, you should set the level of each
individual speaker to achieve an equal balance (see
page 50.)
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.)

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.

Speaker Connection Precautions
Read the following before connecting your speakers:
• American model only: You can connect speakers
with an impedance of 6 ohms or higher. If you use
speakers with a lower impedance, and use the ampli-
fier at high volume levels for a long period of time, the
7
built-in protection circuit may be activated.
✓
• Other models: You can connect speakers with an
impedance of between 4 and 16 ohms. If the imped-
✓
ance of any of the connected speakers is 4 ohms or
✓
more, but less than 6 ohms, be sure to set the Mini-
✓
mum Speaker Impedance to "4 ohms" (see page 32).
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 to only positive
(+) terminals, and negative (–) terminals to only nega-
tive (–) 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.
• Don't connect more than one
cable to each speaker termi-
nal. Doing so may damage the
AV receiver.
• Don't connect one speaker to several terminals.
