Note: instead of adjusting volumes while playing noise and reading the
sound pressure at the same time, it is probably easier to write down the
sound pressure readings for each speaker channel and then adjust the
corresponding speaker levels in the SOURCE SETUP-->SPEAKR LEVEL
submenu. After adjustment, it is recommended to verify it by rerunning
the noise and retesting the sound pressure levels.
3. Starting by TEST button on the infrared remote controller.
SP3 goes to the "Pink Noise" screen and starts playing the noise in the AUTOCYCLE
mode, the same as when selecting it by the front panel through TEST submenu, except
that it will exit automatically after the last speaker channel in the sequence (typically
subwoofer) finished playing.
If one presses TEST button again while any of the channel is playing noise in
AUTOCYCLE mode, the AUTOCYCLE mode changes to MANUAL mode (see
below). Once in the MANUAL mode, pressing TEST button each time increments the
speaker channel through the entire sequence of enabled channels (L,C,R,Rs,Rb,Lb,Ls and
SUB, skipping disabled channels).
Global volume level (-80 to +12dB) can be adjusted when the first channel (L) is played,
while the individual speaker levels (-12 to +12dB) can be adjusted while the other
channels are playing. The test ends when the last channel in the sequence has played or
when the left arrow key is pressed (or POWER is toggled) .
