Connecting your equipment 03

Connecting the speakers

Each speaker connection on the receiver comprises a
positive (+) red, and negative (–) black terminal. For
proper sound you should take care to match these up
with the terminals on the speakers themselves.
If you only have one surround back speaker, hook it
up to the surround back left (
) terminal.
Make sure that all the bare speaker wire is twisted
together and inserted fully into the speaker terminal.
If any of the bare speaker wire touches the back panel
it may cause the power to cut off as a safety measure.
Bare wire connections
Before you start connecting the speakers, make sure that
the speaker cable you’re going to use is properly
prepared with about 10 mm of insulator stripped from
each wire, and the exposed wire strands twisted together

To connect a terminal, unscrew the terminal a few turns
until there is enough space to insert the exposed wire

). Once the wire is in position, tighten the terminal
until the wire is firmly clamped (

Please refer to the manual that came with your
speakers for details on how to connect the other end
of the speaker cables to your speakers.
If you are using a THX certified subwoofer use the
jack on the subwoofer (if your subwoofer
has one) or switch the filter position to

The surround speaker terminals on this receiver can
be connected in a number of ways, depending on
your setup. See

on alternate speaker setups such as using speaker
system B (page 71) and bi-amping (page 72).

Placing the speakers

Where you put your speakers in the room has a big effect
on the quality of the sound. The following guidelines
should help you to get the best sound from your system.
The subwoofer can be placed on the floor. Ideally, the
other speakers should be at about ear-level when
you’re listening to them. Putting the speakers on the
floor (except the subwoofer), or mounting them very
high on a wall is not recommended.
For the best stereo effect, place the front speakers
2–3m apart, at equal distance from the TV.
Install the center speaker above or below the TV so
that the sound of the center channel is localized at
the TV screen.
When placing speakers near the TV, use magnetically
shielded speakers to prevent possible interference,
such as discoloration of the picture when the TV is
switched on. If you do not have magnetically shielded
speakers and notice discoloration of the TV picture,
move the speakers farther away from the TV.
If possible, install the surround speakers slightly
above ear level.
If you have two surround back speakers THX
recommends placing them together and the same
distance from your listening position.
Make sure that all speakers are securely installed.
This not only improves sound quality, but also
reduces the risk of damage or injury resulting from
speakers being knocked over or falling in the event of
external shocks such as earthquakes.
