While still in the "PINK NOISE" mode, repeatedly press the REAR button until the SSD-66
(5.1)'s display reads "NOISE R SURR". The pink noise should be heard on the right sur-
round speaker and the SSD-66 (5.1)'s vector scope will indicate right surround channel
pink noise with a bobbing green line going diagonally downward to the right, from the
center of the display.

Use the VOL UP or VOL DN buttons to raise or lower the pink noise level until the SPL
meter shows a steady 75 dB.
10
Repeatedly press the REAR button until the SSD-66 (5.1)'s display reads "NOISE L SURR".
The pink noise should be heard on the left surround speaker and the SSD-66 (5.1)'s vector
scope will indicate left surround channel pink noise with a bobbing green line going diago-
nally downward to the left, from the center of the display.

SSD-66 (5.1)'s vector scope will indicate both surround channels' pink noise with a bob-
bing green line going downward from the center of the display.

At this point, your SPL meter should be reading a steady 75 dB. If the meter is reading a
slightly lower or higher dB level, use the VOL UP or VOL DN buttons to raise or lower the
pink noise level until the SPL meter shows a steady 75 dB.
Bass Channel Pink Noise - Subwoofer Level
The bass signal, when dealing with digitally encoded software, becomes an important and
distinct component in home theater. No longer is bass strictly a summing characteristic,
combining bass signals from other channels, for Pro Logic playback. With ".1" encoded ma-
terial (5.1), the bass signal is its own discrete signal. Since each system incorporating an
SSD-66 (5.1) will be used for both AC-3 (and DTS) digital playback as well as Pro Logic
playback, the bass handling will need to be both mode and input specific. That is why the
bass control aspects for the SSD-66 (5.1) will be discussed in greater detail under Acoustical
Parameters. In addition to the Input Label specific setup features of bass summing and bass
redirection, bass level control can also be set per input label. However, prior to proceeding
with this setup, the "global" bass level for the home theater system will need to be set using
the SSD-66 (5.1)'s Pink Noise generator.
14
Press the NOISE button twice. The first time the Pink Noise Sequence will engage and the
second press will activate the Pink Noise per Channel. Press the ALL button to engage
Bass Pink Noise.
15
Use the VOL UP or VOL DN buttons to raise or lower the pink noise level until the SPL
meter shows a steady 75 dB.
Acoustical Preset Programming
At this time you will wish to preserve the settings that you have just calibrated for the five main

Press and hold (do not let go) the VOL PRESET. The display will initially indicate "RECALL
VOL". Continue holding down the VOL PRESET button until the display changes to "STORE
VOL". Release the VOL PRESET button immediately after "STORE VOL" is displayed.
Pressing and holding the VOL PRESET button will toggle between "RECALL VOL" and "STORE
VOL". If you are trying to store the volume parameters and have passed the "STORE VOL" indicator,
continue holding the VOL PRESET button until the display returns to "STORE VOL". Release the VOL
PRESET button as soon as the display indicates "STORE VOL".
