Monitor Section
Monitor Calibration cont.
C-weighting is the most wideband weighting filter and most
similar to the human ear at 85 dB
SPL
. Place the microphone in
the listening position and adjust the monitor level pot until you
read 85 dB
SPL
from each loudspeaker. By returning to this level
on program material you have a good chance of obtaining a
constant and accurate reference level.
Dim Level
The monitor section includes a user-specified dim
level that will lower the level of the output feeding
the speakers when the dim function is engaged
(17). Dim can be set anywhere from 0 to -20 dB
Polarity Invert
Engaging the polarity invert function inverts the
polarity of the left channel of the mix, allowing
you to check for stereo “difference” content when
summed to mono, essentially creating a L-R instead
of a L+R sum. The switch is momentary to ensure it
is not left on by accident!
Mono Sum
Engaging this function sums the left and right signals
in the monitor section to produce a mono output.
This is a useful feature for checking any issues that may
arise with out of phase stereo content (especially at low
frequency) and mono compatibility. It is also very useful
to engage during the microphone placement process
(when tracking), by adjusting stereo pair microphones in
mono - until they provide the best tonal balance - thus
hopefully minimising any phase cancellation when
switched back into stereo.
