Solo hierarchy
The solo system add-mode hierarchy works as follows:
The highest level of solos will be the inputs and returns. When active, these will
override and inhibit the remaining solo sources (auxes, matrices and masters).
Within the constraints of the two-level solo hierarchy, only one source can be active
on any channel at any instant:
Input channels: Input channel <--> Aux AFL <--> Direct out <--> Side chain
listen
Return channels: Return channel <--> Direct in
Aux buses: Aux bus <--> Direct in <--> Side chain listen
Matrix outputs: Matrix bus <--> Direct in <--> Side chain listen
Master outputs: Master bus <--> Direct in <--> Side chain listen
An additional constraint is placed on the side chain listen. This is due to the nature
of the DSP, where only one side chain listen can be active on the control centre at
any time, regardless of whatever else is active in the same solo hierarchy level.
If an input channel solo is active via a VCA master solo, soloing the input temporarily
overrides the VCA master solo. However, soloing a direct input or AFL solo on the
same channel or a side chain solo on any channel, cancels both the input solo on
that channel and any VCA master solos to which the input channel is assigned.
Solo in place (SIP)
By using solo in place (SIP), you can cut all channels from the main mix (except soloed
ones) by pressing a solo button. SIP lets you check the contribution from soloed
channels at the actual levels they occur in the mix, that is, taking into account the main
fader setting. If solo buttons cut the main output (main mix) they must only be used in
rehearsals. Sometimes, SIP selection buttons are disabled during recording (solo safe)
or revert to AFL (only affects monitor outputs). See “solo system section” on page 149.
To prevent accidental SIP activation, the SIP button has a hinged clear plastic cover
that has to lifted up before you can operate it.
For SIP purposes, master outputs can be the main master bus or, if configured, a
multi-channel output mix.
To be eligible for SIP muting, channels must be input channels and set up to solo to the
solo A bus; channels with any other combination cannot be subjected to SIP muting.
Channels eligible for SIP muting that are currently or subsequently muted by a means
other than SIP (that is, local button press, auto-mute or scene recall) remain muted,
regardless of the SIP status. On removal of the overriding mute, the mute is restored
according to the current SIP status, see Chapter 13 "Muting" on page 141.
