38. MAIN MIX / MON 1 Switch
This switch allows you to choose if the stereo graphic
EQ [37] is used for the stereo left and right main mix
or if it is used for monitors. For example, there may be
times when the graphic EQ may be used wisely in the
monitor mix to reduce feedback in the monitors from
nearby microphones. Note that this does not affect the
monitors 2 send, only the monitors 1 output.
39. EQ IN / BYPASS Switch
This switch allows you to quickly engage or disengage
the stereo graphic EQ [37]. This may be used for quick
checks of your EQ settings, or to shorten the signal path
if you do not need to use the EQ.
40. MAIN METERS
These peak meters are made up of two columns of
twelve LEDs, with three colors to indicate different
ranges of signal level, traffic light style. They range from
–30 at the bottom, to 0 in the middle, to +20 (CLIP) at
the top.
When a channel is soloed, the right meter shows no
reading, and the left meter shows the level of that
channel’s signal level, pre-fader.
The left meter's 0 dB LED is labeled “level set” to
show where the level should be when adjusting a
channel’s gain [9] in the solo mode.
When0dBu(0.775V)isatthemainleftandright
TRS outputs [30], it shows as 0 dB on the meters.
You can get a good mix with peaks flashing anywhere
between–20and+10dBonthemeters.Mostampliers
clip at about +10 dBu, and some recorders aren’t so
forgiving either. For best real-world results, try to keep
your peaks between “0” and “+6.” Remember, audio
meters are just tools to help assure you that your levels
are “in the ballpark.” You don’t have to stare at them
(unless you want to).
41. RUDE SOLO LED
This large red LED flashes when one or more solo
switches are engaged [22]. This acts as a reminder that
what you hear in the control room and headphones
is the soloed channel(s). If you forget that you are in
solo mode, you can easily be tricked into thinking that
something is wrong with your mixer. Hence, the rude
solo light. Please forgive its rudeness, it is only trying to
help, and wants to be your friend.
