Adjusting The Speajer Levels (Test Tone) - Koss KS4380-2 Instruction Manual

Adjusting the Speaker Levels (Test Tone)
The levels of the five satellite speakers have been preset
at the factory at "0 db". This means that if you were able
to position all of the satellites the same distance from your
normal listening position as recommended, the sound
from all five satellites will sound equally loud at your
normal listening position. This "equality" in the satellites
will provide the most realistic surround sound experience.
However if, because of the size or shape of your listening
room, you are not able to position all of the satellites an
equal distance from your listening position, the TEST TONE
function will allow you to Increase or decrease the levels
of the center and rear speakers to achieve the proper
surround sound balance. Note: You cannot change the
levels of the left front and right front speakers with the
TEST TONE function.
After you have positioned the 5 satellite speakers in the
listening room you can adjust the Center and Rear
speaker levels with the Test Tone as follows:
Note that in order for the TEST TONE function to work,
the system needs to be in stop mode AND the disc tray
must be empty.

3. Press the TEST TONE/MODE button on the remote.
You will hear a "hissing" sound (pink noise) from the left
front speaker for a few seconds. The hissing sound
will move from speaker to speaker as follows: Left ®
Center ® Right ® R Rear ® L Rear, etc. If necessary
press the VOLUME Ù button to increase the master
volume level so you can hear the sound more clearly.
Allow the sound to travel around the five satellites
several times. If the sound level from all five satellites
sounds approximately the same, no further adjustment
is necessary. Press the TEST TONE/MODE button again
to cancel the Test Tone function. It is not necessary
for you to make any further adjustments.
4. If the sound level of the Center of Rear speakers is
higher or lower than the Left front and Right front
speakers you can increase of decrease the level of
those speakers with the CH.LEVEL + or - buttons.
Wait until the "hissing" (pink noise) sound is coming
from the speaker which needs to be adjusted, and then
immediately press the CH.LEVEL + or - buttons to
increase or decrease the level of that speaker. The
range of adjustment is + or - 10 dB in 1 dB steps.
5. After you make the necessary adjustments allow the
pink noise to circle the room a few more times to
confirm that the level of all five satellites sounds the
same at your normal listening position. Re-adjust if
necessary.
6. When you are finished with the level adjustments
press the TEST TONE/MODE button again to cancel
the test tone function.
