The unit is equipped with a built-in test signal generator called a
noise sequencer for easy balance adjustment of all five channels.
The sequencer outputs a noise signal that "travels" from channel
to channel, enabling the simple adjustment of sound level to
achieve the same apparent loudness, at your listening position,
from each channel.
Preparation
• Before adjusting the speaker level balance, be sure to set
the speaker size, distance and existance correctly.
• Before adjusting the speaker level balance, turn off the DSP
surround system.
• Operate the unit while playing the source recorded in Dolby
Digital surround or Dolby Pro Logic.

A noise signal is sent to each channel in turn at the interval of
2 seconds as follows:

C 0dB
L/R 0dB
S 0dB

*L or R flashes to indicate one of the front speakers from
which the noise signal is output.

speakers.
While "❇" or "❘" flashes in the display, press JOG + or - on
the remote control so that the sound level of the centre or
surround speakers matches that of the front speakers.
The balance of the front speakers can be adjusted as well
while "❑✳◗" is displayed.

signal.

• When the noise signal cycles through all the speakers for ten
times, the noise signal stops automatically.

"▼◆▼❉ ", their level balance cannot be adjusted. ("❇✤✴❝❆ " and
"❘✤✴❝❆" are not displayed.)
