Q2 OPERATION AND MAINTENANCE MANUAL 9601 5
Providing a hard centre image in addition to left and right speaker
clusters improves localisation, as has already been proven in the
cinema industry. Stars and soloists are typically mixed to the centre
channel. Back-up vocals and orchestra or band may be wrapped
around the vocalist in stereo, or panned across the three channels.
In Theatrical performances, LCR panning may be used to follow an
actor around the stage.
Q2's typical use in the theatre maybe as follows.
The main LCR output is used to feed the audience clusters. Further
flexibilty in mixing is provided if the 4 LCR sub-groups are fitted,
as groups can be formed with all signals in place, then simply
fader-controlled as a group to the main output.
Four of the auxiliary sends, labelled foldback, may be used to
provide stage monitoring, as the term foldback suggests. The other
four auxiliaries are then free for effects sends, perhaps using the
dual concentric controls as stereo pairs.
The matrix section has numerous uses. Apart from creating foyer
and backstage feeds, it can be used for distributed loudspeaker
arrays for SPL control further back in the house (see the section on
the Q2 matrix). If the Q2 stereo sub-groups are fitted, the matrix is
fully stereo, so that delayed arrays can be easily set up as distinct
and controllable stereo pairs down each side of the auditorium.
