A1.7 General operational summary
1) Always use the same model system controller and power amplifier for a
particular Wavefront product. This avoids confusion caused by different
controller topologies and power amplifiers voltage gains.
2) It is common practice to use mixing console matrix outputs as loudspeaker
section controls. Whilst this is fine for creating a bass submix which can
easily be judged from the mix position, it can be fraught with danger if used
for audience sections which may only be audible in very specific areas. Trim
these remote sections, during listening tests with a colleague via walkie talkie,
using the relevant controller input gains. If the console matrix cannot be
avoided, try to pre-calibrate its output levels controls to their 0dB (nominal)
position initially. These settings will be easier to get back to and will avoid
embarrassing level setting mistakes during the show - particularly if the
system is being used by guest operators who may not be familiar with your
particular matrix allocations.
3) And again, trim levels within clusters (eg farfield vs midfield or inners vs
outers) using the amplifier level controls to ensure limiter tracking.
A1.8 Arraying & placement
Simple stacked systems
Single W8
A single Wavefront W8 cabinet will cover 55º horizontally x 30º vertically and may
be used as a stand-alone system for a variety of light music and voice applications
including commercial presentations.
A W8 may be combined with a W8S compact subwoofer or a WSX horn-loaded
subwoofer to extend its low frequency performance.
