S-1200/ 1200U
4. Calibrate Room Setup
Calibrate volume is where a relative output level for each speaker is set. Level matching for each
of the speakers is measured from the listening position utilizing a SPL meter. The level for each
speaker is to be set to 75db according to the Dolby standard. This is widely accepted as the
standard, however a higher or lower level can be utilized as long as all speakers are set to the same
level for an accurate point of reference. The S-1200/ 1200U outputs a constant pink noise tone for
each of the channels so the calibration can take place. Set the level meter for a slow response time
and C-weighting. The goal is to have all of the levels be as close to 75dB as possible. Each level can
be tuned from -15dB to +15dB in 1dB Increments.
A.
Auto Noise Sequence
– Once auto is selected the automatic noise sequence begins.
Starting from the Left channel the digits indicating dB level directly below the label (LEFT)
will flash. To change the level setting press the enter key. The digits indicating dB level
directly below the label (LEFT) will stop flashing, now using the up and down arrows you
can select the required dB level. Once that level has been set press the enter button again
and the auto setup program will move to the next speaker (CENTER). The auto setup
program will stay on each speaker channel for approximately 3 seconds and then move to
the next speaker channel. Once finished to exit from the auto noise sequence menu press
the previous button or the menu button.
B.
Manual Noise Sequence
– The manual noise sequence works similarly to the Auto Noise
sequence, the major difference being that the automatic portion has been removed. In
manual mode, navigation to each of the speaker components is done using the arrow
keys. Using the arrow keys, navigate to the speaker you want to change, press the enter
button and the digits indicating dB level directly below the label will begin to flash while
the audible pink noise tone will begin. Once the adjustment is completed press the enter
button again, now navigate to the next speaker in need of adjustment.
C.
Program Material
– Program material allows the level adjustment utilizing the movie
sound track or any multi-channel audio from a selected source to be used instead of the
pink noise tone. This mode can be helpful to fine tune the overall sound field while an
actual sound or musical event is being played back. Navigation to each of the speaker
components is done using the arrow keys. Using the arrow keys, navigate to the speaker
you want to change, press the enter button and the digits indicating dB level directly below
the label will begin to flash while selected source audio begins. Once the adjustment
is completed press the enter button again, navigate to the next speaker in need of
adjustment.
