23. CTRL ROOM/PHONES Knob
This adjusts the signal level going to the
CONTROL ROOM [55] and PHONES [50] outputs.
It has no eff ect on the Main Mix output.
WARNING: The headphone amp
is designed to drive any standard
headphones to a very loud level.
We’re not kidding! It can cause
permanent hearing damage. Even
intermediate levels may be painfully
loud with some headphones. BE CAREFUL! Always
start with the CTRL ROOM/PHONE knob turned
all the way down before connecting headphones to
the PHONES jack. Keep it down until you’ve put on
the headphones. The turn it up slowly. Why? Always
remember: “Engineers who fry their ears, fi nd
themselves with short careers.”
24. TAPE TO MAIN Switch
If you have a CD or Tape Deck connected to the
CD/TAPE inputs, push down this switch to add the
CD/TAPE
signal to the main mix. This is useful if you
want to play some entertainment* while the band is
taking a break. Use the MAIN MIX controls to adjust
the volume level.
* We do not mean to imply that your band isn’t
entertaining, or that any other music could possibly
fi ll in for them.
25. SOLO MODE PFL/AFL
Engaging a channel’s SOLO switch will cause this
dramatic turn of events: Any existing CONTROL
ROOM SOURCE selections are replaced by the
SOLO signal, appearing at the CONTROL ROOM
OUTPUTS, PHONES and at the RIGHT METER
(LEFT and RIGHT METERS when in AFL SOLO
MODE). The audible SOLO levels are then controlled
by the CTRL
ROOM/PHONES
knob [23]. The
SOLO levels
appearing on
the meters are
not controlled
by the CTRL
ROOM/PHONES
knob—you wouldn’t
want that. You
want to see the
actual channel
level on the meters
regardless of
how loud you’re
listening.
With the SOLO MODE switch in the up position,
you’re in PFL mode, meaning Pre-Fader Listen (post-
EQ). This mode is required for the “Set the Levels”
procedure and is handy for quick spot-checks of
channels, especially ones that have their faders
turned down.
With the switch down, you’re in AFL mode,
meaning After-Fader Listen. You’ll hear the output of
the soloed channel—it will follow the channel’s GAIN,
EQ, FADER and PAN settings. It’s similar to muting all
the other channels, but without the hassle. Use AFL
mode during mixdown.
In either mode, SOLO will not be aff ected by a
channel’s MUTE/ALT switch position.
Note: Be careful when switching
from AFL to PFL mode. If you have
the channel fader turned down very
much below unity gain (U) while in
AFL mode, switching to PFL mode
will cause a sudden and startling
increase in volume level.
26. RUDE SOLO LED
This large LED lights when a channel’s solo
is active, as an additional reminder beyond the
indicating LEDs on each channel. If you work on a
mixer that has a solo function with no indicator lights
and you happen to forget you’re in solo mode, you
can easily be tricked into thinking that something is
wrong with your mixer. Hence, the RUDE SOLO light.
It’s especially handy at about 3 am when no sound
is coming out of your monitors but your multitrack is
playing back like mad.
Note: In PFL Solo Mode, the RUDE SOLO LED is
green. In AFL Solo Mode, the LED is red.
27. Meters
The peak
meters are made
up of two columns
of LEDs, with
three colors to
indicate diff erent
ranges of signal
level, traffi c light
style. They range
from –30 at the
bottom (–20 on
the Mix.220FX),
to 0 in the middle,
to CLIP (+18) at
the top.
The 0 LED
in the middle is
labeled LEVEL
