Using the test tone
Use the test tone to balance the output levels of the
speakers. The adjustment of each speaker output level
should be made at your listening position using the
remote control.
1 Press AMP to select the
AMP mode.
“AMP” appears in the display
window on the remote control.
2 Press TEST to output the
test tone.
3 Adjust the volume of this unit so you can
hear the test tone.
The test tone is heard (in order) from the main left
speaker, center speaker, main right speaker, rear right
speaker, rear center, rear left speaker, and the
subwoofer. The tone is produced for 2.5 seconds
from each speaker.
This section explains how to adjust speaker output levels
using the test tone generator. When this adjustment is
complete, the output level heard at the listening position
should be the same from each speaker. This is important
for best performance of the digital sound field processor,
and the various decoders (Dolby Digital, Dolby Pro
Logic, Dolby Pro Logic
and DTS).
Note
• Since this unit cannot enter the test mode while headphones are
connected to this unit, be sure to unplug the headphones from
the PHONES jack when using the test tone.
Before you begin

speakers to be used.

main speakers, press both A
and B.
