METERING
METER TYPES
Brio 36 meter types and ballistics can be set globally within System Settings. Available meter options are shown in
the following table:
Input channel, group and main meters all include integrated dynamics meters for Exp/ Gate/ Ducker, Comp/Lim 1 and
Comp/Lim 2 Dynamics modules. Each compressor/limiter meter displays a small ‘C1 or C2’ (compressor/limiter) and ‘E’
(expander/gate) below, which illuminate as the modules are enabled.
All Brio meters include a peak-spot-on meter bar which remains for a short time to make peak monitoring more accurate.
If a signal reaches the clipping point, the meter background turns red and holds for the peak spot duration, then fades out
over one second, letting you trace overloads very easily.
PPM or VU?
VU (Volume Unit) meters use the amplitude and duration of signals to provide an indication of the perceived loudness of a
program. PPM (Peak Program) meters have short attack and long fall-back times in order to give an indication of the peak
amplitude of an input signal.
Fader Meters
Each fader on the Brio 36 surface has a small input meter bar in the fader display. The bottom of each fader display is
shaded to match its attached path type, to ease identification. Fader meters on the external screen provide a wide variety
of essential information including: fader number/ layer/label/scale etc.. an example of which is shown in Figure 1.
