Master Left Right Fader; Tape Return - Mackie SR24•4 Owner's Manual

MASTER LEFT/RIGHT FADER
The MAIN MIX LEFT/RIGHT fader [8] is
a stereo fader located at the far right of the
console. The fader controls the level of the
main L/R mix bus, with precise dB markings
and a unity gain point marked on the panel.
This fader, like the bus faders, is located in
the circuit after the bus insert jack but before
the final line amplifier.
PHONES/C-R LEVEL
For SR (sound reinforcement) work, the
SR24•4 has dual stereo headphone jacks on
the rear panel to enable the sound engineer to
monitor the mix; for recording use there are

jacks to feed a

plifier. Both of
these sets of out-
puts carry the
MAX
main Left/Right
mix, the output of

the solo buses or
the tape return sig-
nal, depending on
switch positions.
The signal level
sent to these out-
puts is adjusted by
the PHONES/
C-R LEVEL con-
trol [9], the small
white knob just
above the MAIN
MIX fader.
TAPE RETURN
The SR24•4 provides
easy monitoring of your
stereo tape recorder,
whether you are using it
in a studio mixing situa-
tion, you're recording a
live gig while you do the
SR mix, or if you just
want to play a little mu-
sic through the system
between sets.
The TAPE RETURN
knob [10] just to the left
of the meters adjusts the
level of the tape playback.
The TAPE
RETURN TO
PHONES/C-R [11]
button next to the
PHONES/C-R LEVEL
routes the tape playback
signal into the monitor system and meters. This
allows you to listen to the playback signal off tape
and to check the playback levels on the SR24•4
meters, even while you are recording.
The TAPE RETURN TO MAIN MIX
switch [12] next to the MAIN MIX fader actu-
ally routes the tape playback signal into the main
Left/Right mix circuits, before the bus insert jacks
and the master fader.
VERY IMPORTANT! This
switch also disconnects
everything else coming up
the L / R buses from the
master fader and outputs.
So, when you push TAPE RETURN TO
MAIN MIX you get only the tape playback
out the main L/R buses.
This feature is designed as a quick and easy
way to play a tape on the main speakers in a live
SR application.
ALSO VERY IMPORTANT! If your
recorder allows monitoring of its input,
assigning the tape return to master could
cause a VERY nasty feedback loop. Be sure
that your tape machine is not in Record,
Record-Ready or Input mode.
Handy Trick: If you have nothing plugged into
the TAPE IN jacks, or have the TAPE RETURN
TO control fully down, you can use the TAPE
RETURN TO MAIN MIX as an oddly-named
MAIN MIX MUTE switch!
