Level controls
The front panel level controls should be turned down (fully counter clockwise) until
FOH-to-Amp rack lines have been checked and controllers have been set to suit the
power amplifiers to be used (see Section 4.5.1). Music should be used to check that
controllers are receiving and sending the appropriate signal bands and then each
power amplifier level control advanced in sequence to check system operation and
patching.
Assuming that controller output levels and limiters have been set as tabulated in
Section 4.5.1, power amplifier level controls should be set to full (fully clockwise) for
loudspeaker sections requiring the strongest drive. Other amplifiers - driving apron
subwoofer sections, for instance - may be backed off as required for smooth coverage.
This process will ensure that the system remains balanced during limiting.
Rack mounting
As with main W8C systems, always leave a 1U space between subwoofer power
amplifiers and controllers. Although most modern amplifiers don’t radiate significant
fields it's better to play safe and keep the system free from hum & buzz. Rear
supports are recommended. Check the manufacturer's application notes for details.
4.7Placement
The WSX is designed to be ground stacked. Ground stacking maintains maximum
efficiency and provides the solid mounting essential for good dynamics.
