Owner`s manual

Pink noise will begin coming from the Left Front
speaker. Press the /\ or \/ (probably the /\) button to
change the noise level by 0.5dB steps until the SPL
meter reads 75dB. There
is an adjustment range of +/- 16dB. Once begun
the noise will move from Left Front to Center to
Right Front to Right Surround to Left Surround to
Sub-woofer.
(If you press either the < or > buttons the sound
will stop circulating and remain at the current
speaker until you press the < or > button).
When you press either the /\ or \/ button the pink
noise will continue to play at that particular speaker
until three seconds after you stop changing the
level. The noise will continually circle the room, so
you can check the levels of the speakers a couple
of times after you believe you have all of them set
to 75dB. Because the SPL meter is less accurate at
measuring low frequencies you might want to
increase the subwoofer level by 5dB or so.
When you are finished and all speakers have the
same relative output level, press ENTER again to
stop the process.
6.6.2 AUTO CALIBRATION
Automatic Calibration is somewhat easier. You
don’t need an SPL meter, as the SSP-75 has its’
own. Insert the battery (correctly) and turn ON the
microphone. Place the microphone at the preferred
listening position (or near the middle of the seating
area), pointing straight up. (The microphone is
omni-directional in a 180 degree arc, 360 degree
around). Be sure the microphone cable is plugged
into the MIC jack on the rear panel of the SSP-75.
Do not attempt to hold the microphone in your
hand, use an independent support. We recommend
propping it up with pillows or attaching it carefully
to a camera tripod. It is also important that the
room be as quiet as possible during this set up.
Too much noise, whether from a furnace, air
conditioner, people talking or just walking around,
may cause the set-up to fail. You can just start
over when there is less extraneous noise.
6.6.2.1 PRESS A.CAL
Press the A.CAL button on the remote. The
monitor screen immediately changes to red
and the following appears:
Pink noise, at a low level, automatically begins from
the Left Front Speaker and rises slowly in volume.
The SSP-75 generates some noise, listens, then step
by step increases or decreases the SPL until the level
of noise coming back from the speaker is equal to
75dB. It tests each speaker in the same sequence as
above, raising the level to 75dB for each one. The
process automatically stops when all speakers have
been successfully calibrated, unless there is an error.
If there is too much noise the process will cease.
It will also stop if the speaker it is attempting to
play is not attached or if the beginning noise level
output from the speaker is to low. (It will skip those
speakers designated as ‘none’ during setup). Merely
fix the problem and start again. The process
generally begins again with the speaker it stopped
at. We have found some sub-woofers are very
sensitive and require their own input level controls
to be reduced somewhat.
Once you have finished with the Level Calibration
of all of the speakers in your theater system you
can press the MENU key again to reach the next
setup level: Delay Setup.
6.7 DELAY SETUP
Some Notes on Delay Setup:
Delay setup is important to your enjoyment of
movies, and any other Surround mode you use. The
purpose of the setup is to tell the SSP-75 where the
listener is sitting in the room, or actually, how far
all the speakers are from each other and from the
listener. The SSP-75 can then send out the sound
from the different speakers at the correct times so
the sounds of an event get to the listeners’ ears in
the correct order.
This is also an easy setup procedure. You can
measure the distance to each of the speakers in
your system and just put the distances into the SSP-
75 or you can utilize the microphone again and
have the processor figure out how far the speakers
are from the preferred listening position. We
recommend you use the microphone, as the
distances will be automatically corrected for
crossover delays.
6.7.1 MANUAL DELAY SETUP
Use the < or > keys to navigate from one installed
speaker to the next. Measure the distance from
the front of each speaker to the SPL meter or
microphone you used in the Level Calibration
procedure above. Use the /\ or \/ keys to increase
or decrease the number on the screen until it
matches the distance you have measured (within
+/- 6 inches).
6.7.2 AUTOMATIC DELAY SETUP
By using the microphone which is in the preferred
listening position, and using the A.CAL button
you can get the SSP-75 to measure the distance
more accurately.
Press the A.CAL button at any point. Even if
you have set the distances, or even set half the
distances, you can press the A.CAL key and the
processor will begin sending out a series of short,
high pitched noises, moving from speaker to
speaker as it figures out how far each speaker
is from the microphone. The noises may seem
loud, but they will not damage your speakers.
The processor ‘measures’ the time it takes for
the noise to reach the microphone after it has
been played by each speaker.
Again, it is very important there not be any other
noise going on in the room at the same time as the
processor is attempting to set the distances.Once
you have finished with the Delay Setup of all the
speakers in your theater system you can press the
MENU key again to reach the next setup level:
