To configure the Model PT-7000 for your speaker system
:
1. Press the MENU button to enter the Main Menu.

3. Press SELECT to enter the Speaker Conguration menu.
The Speaker Conguration menu appears on the Front Panel Display and
the OSD (see gure 2). The selected menu item should be
FRONT
.
The rst three settings in the Speaker conguration menu deal with
the type of speakers you are using in your system. It is very important
that you understand what is meant by the LARGE and SMALL settings
in this menu. They do not refer to the physical size of the speakers, but
to their ability to handle very powerful deep bass. Most loudspeaker
systems on the market should be classied as Small, since they do not
have the capability to handle the often extraordinary amount of deep
bass content lm soundtracks can contain.
It is strongly recommended that you consult your loudspeaker instruc-
tion manual regarding the capabilities of your particular system with
regard to low bass/low frequency reproduction.
Please note that all THX certied loudspeaker systems are classied
under this method as SMALL since a subwoofer is required for any THX
certied loudspeaker system.
In any case you should consider using a subwoofer for any system which
you expect to effectively handle the low frequency dynamics of modern
motion picture soundtrack sources such as DVD or HDTV feeds, and
many other discrete multi-channel programming sources.
If you aren’t sure about your speaker’s real world capabilities and you
are using a subwoofer, choose Small, since this will insure that all the
appropriate low frequency information is directed to the subwoofer where
it can be most effectively handled.
4. Use the < and > buttons to cycle through the speaker options for
the FRONT speaker.
The following options are available for each group of loudspeakers:
For FRONT you can select
SMALL
or

For CENTER you can select

For SURR(OUNDS) you can select

,
LB/RB

LB/RB means you have a Left Back and Right Back rear surround
speaker setup for use in a 7.1 conguration. BS(LB) means you
have a single centrally placed BACK Surround speaker for use in a
6.1 (EX) type conguration.

5. Press the button when you have made a selection.
Repeat steps 4 and 5 until you have completed selecting the speaker type
for each loudspeaker in your system.
6. Press the button when you are nished to select the Front
Crossover (XOVER) menu.
The Front, Center and Surround Crossover menus are used to indepen-
dently set the internal High Pass lter of the PT-7000’s Cirrus Triple
Crossover for each of these three speaker groups.
7. Use the < and > buttons to adjust the Front Crossover.
The crossover settings appear as follows as you scroll through them:
40Hz60Hz80Hz100Hz120Hz150Hz
You can scroll in either direction using the < and > buttons .
Consult the material that came with your loudspeakers to determine the
correct settings, if any are recommended. The THX standard is 80Hz. We
recommend you set all speakers for no lower than 60Hz and preferably
80Hz unless otherwise directed by the manufacturer. If you are using
very small satellite speakers you may need to set the crossovers to 100 or
even 120Hz. When correctly set, you should hear a smooth transition of
lower to upper bass between the satellites and the subwoofer.
8. Press the button when you have made a selection.
Repeat steps 7 and 8 until you have completed the speaker crossover
settings for each group of speakers.
9. Press the button to select the Return to Main Menu option.
10. Press the SELECT or MENU button to return to the Main Menu, or
press the MENU button twice to exit the menu system.
