4 - Using the ARC 2 Measurement
3 5
ARC System 2
Example 5
Project studio (figure 4.16).
figure 4.16
Main position is marked as 1 and it is perfectly centered between the two
speakers at the main listening position. This is the position you should use
to calibrate levels and for the 1st measurement.
All other measurements are symmetrical to an imaginary central line, so
measurements after the first one (Main position) are taken alternatively on
the Left and Right side.
A minimum of 7 measurements is needed but, as shown in figure 4.16, we
suggest to take at least 11-16 measurements.
Please note that these are just examples. Since all rooms are different, you
should experiment with various measuring patterns and take several mea-
surement sets to maximize the ARC System 2 capabilities and expand your
monitoring options. Then you can store all measurement sets and recall
them later in the ARC 2 Plug-In allowing for direct on-the-fly comparisons.
It should be noted that the quality of the correction curve is only as good as
the accuracy and care taken when doing measurements. Since the measure-
ment process is supposed to be done only once, we strongly suggest giving
this process the importance it deserves.
See the next paragraph for a step-by-step description of how to take all
measurements.
