Techno Tidbits & Problem-solving
Speaker Placement for a Complete THX Speaker System
If you have a complete THX Speaker System set (LucasFilm authorized), follow the diagram below to
place your speakers.
Notice the surround speakers should output at an angle parallel to the listener. Also, notice the angle
of the front speakers.
If you have two surround back
speakers we recommend placing
them together and the same dis-
tance from your listening position so
you can take advantage of the ASA
feature. For more details see page
108.
Speaker Placement for DVD-A (etc.) Sources
The best speaker placement for DVD-A (and other
multichannel music sources) may be different than for regu-
lar DVD discs. For these formats follow the diagram at right
as opposed to the home theater setups of the preceding
pages. If you want to use both home theater and DVD-A
discs (through the MULTI CH INPUT) follow the diagrams
below and set up your MULTI CH IN SELECT output mode
accordingly.
In order to choose the best MULTI CH IN SELECT output
mode (see p.101) use the diagrams here. Find the diagram that most closely resembles your surround
and surround back speaker setup and then chose that output mode.

*In this diagram the white sound waves represent the actual transmitted sound and the shaded sound
waves represent the how the sound will seem to the listener (the virtual sound).
This setting is only achieved when listening to input sound from MULTI CH INPUT terminals. To
achieve a similar effect at other times, set the listening mode to STANDARD SX.
