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 A2.5.1). 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 controllers have been set as tabulated in Section A2.5.1, power

amplifier level controls should be set to full (fully clockwise) for loudspeaker sections

requiring the strongest drive. Amplifiers driving nearer-field section within the same

cluster may be backed off as required for smooth coverage. This process will ensure

that the cluster coverage remains balanced during limiting.

Rack mounting

As with main W8 systems, always leave a 1U space between big 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.
