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 Evolution 707 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.
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 fl ash.
To change the level setting press the enter key. The digits indicating dB level directly below
the label (LEFT) will stop fl ashing, 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 fi nished to exit from the auto noise sequence menu press the previous
button or the menu button.
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 fl ash 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.
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 fi ne tune the overall sound fi eld 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 fl ash while selected source audio begins. Once the adjustment is completed press the
enter button again, navigate to the next speaker in need of adjustment.
