13 System Configurations & OEM Controllers
With the vast array of digital loudspeaker management systems available it is inevitable that the user
may opt to use a controller other than the TX1 & TDX2 as part of a large scale integrated system. The
V8 has been designed to need no external equalisation to overcome system limitations. If the V8 is
to be used alone with additional bass enhancement required and have the frequency response limits
tighter than +/- 3dB as stated in section 11, then apply the parameters in the table below for
optimised performance:-

8. Arraying
As discussed in the previous section, comb filtering is a phenomenon, which cannot not be cured by
equalisation. Small alterations to loudspeaker positions can have the effect of minimising problematic
combing frequencies. Arrays should be constructed so that the individual coverage patters of each
loudspeaker combine with minimal overlap. The design of the V8 cabinet greatly simplifies the
creation of effective arrays, allowing seamless wide (140 degree) horizontal coverage using two
loudspeakers without the need for tedious experimentation.
By placing the V8 cabinets with the 30 degree angled rear panels together, minimal dispersion
pattern overlap is achieved, guaranteeing an extraordinarily smooth transition.
In many applications the 90-degree dispersion pattern may be sufficient in the horizontal plane.
It is also possible to stack the cabinets vertically using the above method, say for use in a central
cluster, where greater vertical dispersion is required.
9.
As shown in the above diagram, one of the V8 cabinets is inverted to allow the optimum splay
angle to be achieved. The grill can be simply removed from this cabinet and be replaced in the
correct orientation. The grill is held in position by the two fixing screws on the top and bottom
lips of the cabinet.
