Aiming
The W8VDQ can cover approximately 30deg vertically. The easiest way to set the tilt angle for maximum
rear audience level is to aim the top section of the grille straight towards the furthest seat.
See
Maximum level to farfield
line below…
Note that the W8VDQ’s differential dispersion does not allow vertical arraying or stacking. The Martin Audio
W8LM line array system provides optimal vertical coupling for vertical array applications.
Horizontal arraying (up to 60-100deg between W8VDQs) is possible.

Choosing a power amplifier
Martin Audio loudspeakers are capable of recreating musical dynamics accurately and with incredible
impact if powered correctly. Martin Audio loudspeaker power ratings are quoted for
AES
power - a long-
term average power rating, and
Peak
power – a short-term burst capability.
Moving coil loudspeakers can be run up to their
AES
power rating continuously and up to the higher
Peak
power rating for transient musical peaks.
1) Choose an amplifier with a power capability approaching 3200W into 6ohms. This means choosing a
Martin Audio MA9.6 or MA12K power amplifier.
2) For spectral balance, set your amplifiers to the
same voltage gain throughout the system
. A
common industry standard voltage gain is 32dB (x40). All Martin Audio limiters are set for this level.
3) If you use Crown amplifiers without a 32dB setting, set them to their 26dB (x20) standard and increase
the recommended limiter thresholds by 6dB – making sure you double-check the amplifier gain setting
before running the system at high level. Always check the amplifier
gain
settings – these are usually on
the rear panel.
4) Avoid
using
sensitivity
settings as these give different gains depending on the amplifier’s power
specification.
