Chapter Two : Setting Up PowerTouch
SP Level
In this step you will use your ears to balance the volume level
of all the system's speakers except the subwoofer for your room
and listening position. (To set the subwoofer level, see "Set-
ting the Subwoofer Level" on this page.) When all the speak-
ers are set at the same volume level, your system will create a
more realistic, spacious surround sound environment.
It is recommended to use a SPL meter to adjust the speaker
levels accurately. (See "To obtain accurate output levels" on
this page)
When setting the speaker levels, be careful against the
high-level test tone that is produced.
1. Eliminate as many external noise sources as possible.
2. Sit in the place where you and your guests are most likely
to sit while watching movies or listening to music.
3. If you are not already there, touch
Setup Surround menu to open the Speaker Level menu:
4. Touch
until the Test Tone display reads "Manu".
5. Test noise will play from the front left speaker. Care-
fully listen to the volume level of the noise.
6. Touch
or
to select the next speaker.
7. Carefully listen to the volume level of the test noise. If
the noise is a different volume than the noise from the
front left speaker, use
or
ume so that the volume matches the volume from the
front left speaker.
(Do not be concerned with the volume number read-
out on the Level display—this is for reference purposes
only. Use your ears to determine if the two speakers are
playing at the same volume).
8. Repeat steps 6 and 7 until all the system's speakers (except
the subwoofer) play at the same volume.
9. To confirm the volume levels, touch
Tone display reads "Auto". The test noise will automati-
cally cycle between all of the speakers. Fine-tune the chan-
nel levels as necessary.
10. When all the channels sound like they're the same vol-
ume, you've balanced your system.
11. To turn off the test noise, touch
display reads "Off".
Setting the Subwoofer Level: Because of the way hu-
mans hear, the test noise the Speaker Level menu sends
on the
through the subwoofer will not sound as loud as it re-
ally is. (The Speaker Level menu subwoofer test noise is
designed to be used with a sound pressure level meter
for balancing.)
Because of this, you cannot use that test noise to prop-
erly calibrate the level of your subwoofer by ear. To set
the subwoofer level, listen to familiar music or films
that have strong bass content and adjust the subwoofer
level until it sounds balanced with the rest of the speak-
ers.
12. Touch
to move to the next speaker setting or touch
to return to the Setup Surround menu.
To obtain accurate output levels
To obtain accurate output levels, it is recommended to use
a handheld Sound Pressure Level (SPL) meter. Readings
should be taken from your actual listening position and
adjust the level of each speaker to 75 dB SPL (C-weighted/
slow meter mode).

Bass Peak Level
In this step, you set the maximum volume of the bass sound
so that the speaker sounds are not distorted even when
excessively-large bass signal is input. When playback is
performed hereafter, the bass sound is regulated automatically
so as not to exceed the level set here.
