4.9.5 Mic Position
The SRA and SSD wizards do all of the calculations and complex routing through the
StudioLive for you. Two very important decisions are up to you: Where to place the
mic and, in the case of the SRA wizard, what to do with the frequency-response trace.
Improper mic placement can create “problems” in your trace
that actually don’t exist in your sound system.
Primary Mic Position
This is the main reference point for a speaker and can be used
as a single, “representative” position if you’re short on time or
patience and just want to get a “gut check” of your system.
Your goal in setting the primary mic position is to find a point that puts
the microphone in the center (on axis) of a speaker’s throw, within
the listening area. In other words, you want to put the microphone
smack dab in the middle of where your speaker sounds its best.

Secondary Mic Position
You will use two different secondary positions in a multi-point measurement. These
can be on- or off-axis measurements of a speaker within the listening area. This will
allow the SRA wizard to create an average frequency response of your sound system.
Avoid using locations outside the core coverage area of your system or on the edges.
The graphic below displays some good secondary measurement positions relative
to the primary position, as well as some positions that would be more problematic
than useful. With any mic position, avoid creating position-related anomalies.
