If you are using the STUDIO output to drive a pair of +
monitors actually in the studio, do not ever leave P82
turned up during a take. Howls and howlround may well
be the result.
Lastly, there is a MONO button (S86), useful for checking the phase
correlation and/or coherence of a stereo signal. Again, this does
not affect the main mix output.
Headphones6.4
Both HEADPHONES 1 & 2 masters are identical.
PhonesFig. 6.5:
A SOURCING matrix picks up any or all of MIX-B (S76), CONTROL
ROOM (as chosen in monitor section, S77), AUX 3/4 (S78), AUX
5/6 (S79) and EXTERNAL (S80). In addition to the sources which
are directly selectable from the headphones masters, aux returns
3 to 6 may be “force-fed” into HP1 & HP2 from the aux returns
masters (S55, S56, etc.).
The headphone mix level is controlled by a master volume pot
(P75), and the gain is sufcient to drive headphones directly.
This is ne for a MIDI suite with overdub booth, but for the big-
ger studio’s headphone network we’d recommend using a
separate headphones distribution amplier like our BEHRINGER
POWERPLAY PRO HA4400. This can offer the added advantage
of independent headphones level control for every performer.
A SOLO button (S81), with its own LED, enables monitoring of
the headphones amplier’s output signal.
This way the engineer can monitor what’s going on in the cans
on the control room monitors, though in our experience this does
not give as true a picture as auditioning the cue feed from a set of
headphones identical to those worn by the performer(s).
PFL/SOLO6.5
Solo sectionFig. 6.6:
PFL6.5.1
Pressing S95 disengages the stereo SOLO bus, and replaces it
with a separate mono PFL (Pre-Fader-Listen) bus. Now anything at
all which is SOLOed, isn’t. It is PFLed instead. PFL should be used
for gain-setting. (See also the essential section 13 “Start-up”.)
SOLO6.5.2
SOLO is short for SOLO IN PLACE, and is the preferred method
for auditioning an isolated signal or a group of signals. Whenever
a SOLO button is pressed, all unselected channels are muted
in the monitors. Stereo panning is maintained. The SOLO bus
is derived from the output of the channel PANs, aux send/return
pots, etc., and is always post fader.
In addition to any local solo LEDs which might be activated, the
ultra-bright MAIN SOLO LED (L95) illuminates whenever anything
is SOLO/PFLed. P94 controls the master SOLO/PFL level. Set to
unity gain (center detente), this will match the mix level.
Talkback6.6
TalkbackFig. 6.7:
The built in mic (above the main mix faders) allows you to converse
with artists remotely. The most important controls are the VOLUME
(P99) and PHONES & STUDIO button (S99, see g. 6.7). It is
possible to route the talkback mic to any of the following: aux 1,
aux 2, subgroups, and phones and studio (S96 to S99).
Complex headphone or stage monitoring networks could be
constructed where HP1, HP2, aux 1 (pre), aux 2 (pre) and one or
more subgroups all feed separate monitor mixes. (See section 16.2
“Very tricky headphones”).
However, since the four pushbuttons are non-latching it might drive
you crazy. If you are using many headphone feeds, you may nd
it easier to patch a separate microphone for talkback straight into
a channel, where it can be routed pretty much anywhere.
Engaging TALKBACK (S99) dims the control room (monitors, not
lights) by -20 dB to restrict the possibility of feedback. All other
talkback routes are unaffected.
