1 7 MC2.1 - Monitor Controller
Holding the SPL - Set the meter to C weighted and on the slow scale. Start by sitting
in your normal mixing position, hold the SPL meter at arm’s length and at chest
level with the microphone of the meter facing toward the monitor to be calibrated.
Maintain this position throughout the calibration process - this could be easier if it
is fixed via a stand and bracket, and moved only to point at the relevant speaker.
The following method sets the sound pressure level to 85dB - the standard listening
level for film, tv and music, however, due to the sound being altered by the size of
the room, this can alter, essentially, the smaller your room is, the lower your listening
level should be, down to around 76dB. The following table should give an idea of
the sound pressure level to use for your environment.
