AVR
Step One - Determine Your Speakers' Crossover Frequencies
Without using the EzSet/EQ process, the AVR can't detect how many speakers
you've connected to it; nor can it determine their capabilities. Consult the technical
specifications for all of your speakers and locate the frequency response, usually given
as a range, e.g., 1OOHz - 20kHz (±3dB). Write down the lowest frequency that each of
your speakers (except the subwoofer) is capable of playing (1OOHz in the above example)
as the crossover in Table A3 in the Appendix. NOTE: This is not the same as the crossover
frequency listed in the speaker's specifications.
The AVR's bass management determines which speakers will be used to play back the
low-frequency (bass) portion of the source program. Sending the lowest notes to small
satellite speakers will result in bad sound and may even damage the speakers. The
highest notes may not be heard at all through the subwoofer.
With proper bass management, the AVR divides the source signal at a crossover frequency.
All information above that crossover frequency is played through your system's speakers,
and all information below the crossover frequency is played through the subwoofer. This
way, each loudspeaker in your system will perform at its best, delivering a more powerful
and enjoyable sound experience.
Step Two - Measure the Speaker Distances
Ideally, all of your speakers would be placed in a circle, with the listening position at the
center. However, you may have had to place some speakers a little farther away from
the listening position than others. Because of this, sounds that are supposed to arrive
simultaneously from different speakers may blur, due to different arrival times.
Your AVR provides a Distance adjustment that compensates for these real-world speaker
placement differences.
Measure the distance from each speaker to the listening position, and write it down
in Table A4 in the Appendix. Even if all of your speakers are the same distance from
the listening position, enter your speaker distances as described in Set the Speaker
Distances, on page 32.
Step Three - Manual Speaker Setup Menu
Now you are ready to program the AVR. Sit in your usual listening position, and make the
room as quiet as possible.
With the AVR and video display turned on, press the OSD/Menu button to display the
menu system. Select the Speaker Setup menu, and then select Manual Setup.
If you have already run the EzSet/EQ process as explained in Configure the AVR tor Your
Speakers, on page 22, the AVR saved the results. To fine-tune the EzSet/EQ results, or
to configure the AVR from scratch, select Manual Setup. The Manual Setup screen will
appear.
Advanced Functions
NOTE: To save the current settings, press the Back/Exit button.
For best results, adjust the submenus in this order: Speakers, Crossover, Distance and
Output Adjust.
Speakers
This selection lets you program the correct setting for each speaker group. The settings
in this menu affect the remainder of the speaker setup process and the availability of
various surround modes at any time.
Select ON when the speakers are present in the system; select OFF for positions where
no speakers are installed. The Front Left & Right setting is always ON and may not be
disabled.
Any changes will be reflected in the total Number Of Speakers displayed at the top of
the screen.
AVR 171 OS/AVR 171 S only: The Assigned AMP setting includes four options:
• Surround Back: Select the Surr. Back option if your main system is a 7 .1-channel
system and you are using surround back left and surround back right speakers.
• Zone 2: Select the Zone 2 option if your main system is a 5.1-channel system and
you want to use the Assigned Amp speaker outputs to power speakers in Zone 2. See
Install a Multizone System, on page 19, for more information.
• Front Height: Select the Front Height option if your main system is a 7.1-channel
system and you are using Front Height speakers with Dolby Pro Logic liz.
• Off: Select Off if you have not connected speakers to the Assigned Amp speaker
outputs.
NOTE: When you set Assigned AMP to "Zone 2," the speakers connected to the Assigned
Amp outputs will not be configured during the EzSet/EQ process. Configure the speakers
manually, as explained below.
When you have finished, press the Back/Exit button.
Crossover
After you return to the Speaker Setup menu, navigate to the Crossover line and press the
OK button to display the Crossover menu.
The AVR will display only those speaker groups you set to On in the Number of Speakers
menu.
Refer to Table A3 to see the crossover frequencies that you wrote down for your
speakers.
