Metering Bus Meters 1-8; Main/Solo Meters; Aux Sends - Mackie 16-8 BUS Owner's Manual

METERING
Bus Meters 1-8
Directly above each bus fader is a peak-reading
meter displaying the bus output level. Zero (0) on
the meter references a level of +4dBu (1.23 volts
RMS) at the output jack.
Note: If the –10dBV switches are engaged at the
Subgroup output jacks, then zero (0) on the meter
references a level of –10dBV at those outputs.
Note: When any SOLO switch is engaged, the
SUBMASTER meters will be extinguished in or-
der to divert your attention to the SOLO/MAIN
meters (discussed below).
MAIN OR SOLO LEVEL Meters
The MAIN OR SOLO LEVEL meters display the
L/R Main Mix levels and are similar to the bus
meters, with these exceptions:
• If a SOLO button is depressed, the meters
display the output of the soloed
signals; if not, the meters show the
level of the signal selected by the
MONITOR SOURCE switches. In
other words, you are always meter-
ing what you're listening to.
IMPORTANT:
When the console
is in SOLO mode,
zero (0) on the
SOLO/MAIN
meters references the actual
internal operating level, or 0dBu
(.775v). If you have just one signal in
the main L/R path and you SOLO it,
the meter level will jump up 4dB.
Don't be alarmed. If you're mixing on
the L/R buses, that's what you'll
meter. If you're checking a tape
playback, that's what you'll meter.
When the meters are following the
monitors (not in SOLO), zero (0) on
the meter references a level of
+4dBu (1.23 volts RMS) at the main
L/R outputs, just like the submaster
meters.
Note: The solo levels displayed on
the meters are PRE-solo level,
thus giving you an accurate
showing of the total level of the
soloed signals.This is also the way
to set initial console levels. See the
discussion of the SOLO function,
earlier in this section.
• Additional red LEDs per side at
the top of the meter show output
clipping at +28dBu balanced,
+22dBu unbalanced. (You don't want these
to ever go on. If they do, try pulling down the
L/R master fader a little.)

AUX SENDS

The six auxiliary send outputs each have a
master level control. Like any level control, turn-
ing the knob turns the volume up or down.
However, the gain of the AUX Sends has been
optimized at the unity (center detent) setting
and should not need adjustment.
The output of each bus is available at its AUX
Send Out jack in the jack panel above. Addition-
ally, AUX Sends 3 & 4 and AUX Sends 5 & 6 are
fed as stereo pairs to the two PHONES SOURCE
switching matrices, for headphone cueing
purposes.
