Chapter 12: Soloing
With solo you can isolate the sound from a single channel, which is helpful in
fault nding and when equalising a signal. Pressing a solo button cuts all signals
routed to the monitor output, except the one local to the solo button (mix minus
is bus mode of the aux outputs, and does not aect the solo buses — if you solo
an aux in mix minus mode, you still only solo that channel). So, you can monitor a
signal at a level proportional to its level in the mix, in the same stereo position in
the mix and with the same reverberation as in the mix.
The PRO X Control Centre has two independent solo systems, solo A and solo
B. Both have monitor and headphone outputs, and both can be used to PFL or
AFL signals from the same sources throughout the control centre. This exible
solo bus conguration makes soloing of three-way monitor mixes — in-ears
going to solo A and wedge going to solo B — possible and also greatly
enhances the usefulness of the control centre for dual (two-person) operation
(independent soloing).
Note: Solo A and B are not to be confused with area A and B (as in dual operation)
and monitor A and B.
Using solo A/B
With solo A/B on, solo goes to the selected solo bus with the
following conditions:
• If the solo button is pressed only for a short time, the soloing to the selected
solo bus remains active when the button is released. If the solo button is held
down, the soloing to the selected solo bus is cancelled when the button is
released.
• Pre-fader audio is sent to the selected solo bus if the associated PFL control
for that bus is active. Post-fader audio is sent to the selected solo bus if the
associated PFL control is inactive.
• Unless multiple solo activations to the same solo bus are concurrent, the solo
activation that occurred last — while the respective solo add mode (A or B) is
inactive — cancels all earlier solos to the same bus before it activates.
• Solos can also be operated from a VCA master when the channel to which they
belong is a member of that VCA. This is in addition to the local operation.
• Pressing the solo clear button associated with the solo bus (A or B) they are
sending to will clear active solos.
• A solo hierarchy exists for each of the solo buses in the control centre (see
“Solo hierarchy”). Activating a solo with a higher precedence in the hierarchy
deactivates all solos with less precedence and inhibits them from being
operated. As soon as the higher precedence solos are cleared, the stages of the
inhibited solos are restored and they resume normal operation.
Some modications to this hierarchy are possible. For example, mix buses
can be used as sub-mixes (hierarchy is as described) or outputs (having same
precedence as master outputs).
• Pressing ADD (solo A/B) o cancels all solos.
• Soloing inputs and outputs (with solo add switched on):
• With any inputs active, you can’t solo outputs.
• With any outputs active, pressing an input solo overrides (cancels) the
output solo. Then, if you cancel the input solo(s), the output solo(s) returns.
The eects of using the solo A and B buttons in combination are shown in the
following table.
Solo A Solo B Eect
O O
Solo goes to the A bus, but there is no solo
in operation.
On O Solo goes to the solo A bus.
O On Solo goes to the solo B bus.
On On Solo goes to the solo A bus.
The eects of using the solo destination controls are shown in the
following table.
Table 10: Solo A/B destination controls
Control Description
PFL direct input
Direct inject to solo A from linked control
centre, active only while solo A is PFL.
AFL direct input
Direct inject to solo A from linked control
centre, active only while solo A is AFL.
PFL direct output
Mono summed direct output from solo A for
linking to another console.
AFL direct output
Stereo direct output from solo A for linking to
another console.
Solo add:
•On (additive solos)
•O (self-cancelling solos)
Disables self-cancelling solo A/B solos.
(When self-cancelling solos are selected,
that is, with solo add mode o, the solo
being cancelled should be deactivated before
activating a new solo.)
Solo clear:
•On (some solo A solos)
•O (no solo A solos)
Single button clearing of currently active solo
A/B solos.
Solo PFL:
•PFL (solo pre-fader)
•AFL (solo after-fader)
Switch all current and future solo A/B
activations to send the solo A/B bus pre-fader.
Solo in place (SIP):
•On (SIP active)
•O (SIP inactive)
When active, SIP mutes all channels except
the one being soloed. However, the audio
of the soloed channels is still placed on the
monitor outputs. For more information on SIP,
see “Solo in place (SIP)”.
