Adjusting Speaker Level Balance - Aiwa AV-NW30, AV-NW31 Operating Instructions Manual

ADJUSTING SPEAKER LEVEL
BALANCE
BALANCE
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.
1 Turn SURROUND on.
2 Press and hold MANUAL SELECT on the remote
control until "L" of "L/R 0dB" starts to flash.
A noise signal is sent to each channel in turn at the interval of
2 seconds as follows:
L/R 0dB (Left front speaker)*
(Center speaker)
C 0dB
L/R 0dB
(Right front speaker)*
S 0dB (Right surround speaker)
S 0dB (Left surround speaker)
* L or R flashes to indicate one of the front speakers from
which the noise signal is output.
3 Adjust the sound level of the center and surround
speakers.
While "C" or "S" flashes in the display, press JOG + or - on
the remote control so that the sound level of the center or
surround speakers matches that of the front speakers.
The blance of the front speakers can be adjusted as well while
"L/R" is displayed.
4 Press MANUAL SELECT again to stop the noise
signal.
NOTE
• When the noise signal cycles through all the speakers for ten
times, the noise singal stops automatically.
• When the center speaker and/or surround speakers are set to
"NONE", their level balance cannot be adjusted. ("C 0dB" and "S
JOG +,-
0dB" are not displayed.)
