1.11 W8Cs as side clusters
A Wavefront Longthrow (See Section 2) centre cluster may be used with W8C
downfills for efficient operatic and orchestral amplification. Velodrome side seats can
be some distance away (typically across a wide cycle track) so fairly powerful side
clusters may be required for good projection and intelligibility.
W8Cs are ideal for this application as they blend in sonically without off-axis lobing
and stage mic colouration.
Deep orchestral stage continues this way ñ
To avoid abrupt changes in timbre between the side and centre cluster, the side
downstage W8C axis should be aimed at the seating where the centre cluster is just
beginning to lack very high frequencies.
Controller output levels and delays should be adjusted so that the side and centre
clusters are at the same level and sychronised in the same area.
