Global Setup - Channel Balance & Volume Preset
This section pertains to balancing the speaker channels. The SSD-66 (5.1) has a built-in
"pink noise" generator that permits you to raise and lower individual channels' volume levels
to precisely set volume levels in your room. While it is possible to set the speaker levels by
listening to each channel, it is recommended to follow these procedures using a Sound Pres-
sure Level Meter (SPL Meter).
Pink Noise
The SSD-66 (5.1) has two "pink noise" modes. One permits you to select a channel and
manually switch to another channel when you are ready ("PINK NOISE" mode). The second
"pink noise" mode automatically sequences through all speaker channels ("PINK NSE SEQ"
mode). The first mode is typically used during initial setup and the second mode is used for
confirming final calibration by automatically providing sweeps of the entire speaker array.
To engage the SSD-66 (5.1) "pink noise" generator:
1
Press the NOISE button. The SSD-66 (5.1)'s display will read either "PINK NOISE" or
"PINK NSE SEQ". To toggle between "pink noise" modes, repeatedly press the NOISE
button.
2
To exit the SSD-66 (5.1)'s "pink noise" generator, press either the INPUT SELECT button
at any time.
Initial Channel Balance
Typically, it will be easier to balance channels correctly with the "pink noise' generator set to
"PINK NOISE" rather than "PINK NSE SEQ". Situate the SPL meter in the center of the room
and make certain that the meter's range is capable of reading 75 dB. Additional SPL meter
settings call for the unit to be set to "C-Weighted, Slow Mode".
Front Channel Balance
1
Repeatedly press the NOISE button until the SSD-66 (5.1)'s display reads "PINK NOISE".
2
Press the CENTER button. The pink noise should be heard on the center speaker and the
SSD-66 (5.1)'s vector scope will indicate center channel pink noise with a bobbing green
line going upward from the center of the display.
3
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.
4
Press the RIGHT button. The pink noise should be heard on the right speaker and the
SSD-66 (5.1)'s vector scope will indicate right channel pink noise with a bobbing green line
going diagonally upward to the right, from the center of the display.
5
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.
6
Press the LEFT button. The pink noise should be heard on the left speaker and the SSD-
66 (5.1)'s vector scope will indicate left channel pink noise with a bobbing green line going
diagonally upward to the left, from the center of the display.
7
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.
Surround Channel Balance
The surround channels need to deliver an SPL reading of 75 dB when pink noise is played
through both speakers simultaneously. However, you will want to balance the two channels
individually prior to setting the pink noise for both surround channels. The SSD-66 (5.1)
permits you to select the left, right, or combined rear channel noise by repeatedly pressing the
REAR button. This will toggle the SSD-66 (5.1) between the rear channel pink noise options.
