Telex Q II - FOH specifications Q2 in USE

THE Q2 IN USE

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.
