ARC System 2
sider the main position as a point in the middle of the speakers at a distance
where you usually sit when working on your mixes.
4.5.1 Microphone orientation
The ARC 2 Measurement Microphone must be positioned VERTICALLY for all
ARC 2 measurements (figure 4.6).

Do not attempt to measure the room by pointing the microphone at the
speakers, because all measurements will be wrong, and the resulting cor-
rection will be wrong as well.
After securely clipping the microphone on a standard mic stand, be sure to
point it at the ceiling. Ideally, the microphone should be perfectly perpen-
dicular to the floor.
Try to use a mic stand with a boom arm that is extended as far away from
the stand as possible. This helps avoid reflections from the stand that will
interfere with the measurements at high frequencies. Do not stand or sit
near the microphone while the measurements are running.
