Front Panel Controls
• The only control designed to always be available is the Power Switch. In
the ON position power is supplied via the AC Mains, the Power LED will be
Green, the Digital Crossover section of the XTD is enabled, and the Analog
crossover is disabled. When the Power Switch is in the OFF position, power
is supplied by the Emergency Bypass Supply, the Power LED will be Red, the
Digital Crossover section of the XTD is disabled, and the Analog crossover is
enabled.
• Behind the access panel are the Digital Configuration switches, Analog
Crossover Mode selector switches, and the volume controls for the nine
outputs. Digital Configuration switches allow for 100 different speaker
configurations as identified in the Appendix.
Analog Crossover Mode selector switches allow the emergency bypass
circuitry to be configured for two-way or three-way systems and should be set
to match the Digital Configuration. Up (or On) is two-way; Down (or Off) is
three-way.
The Volume Controls allow the nine output signal levels to be adjusted. These
work in either the Normal or Bypass modes and adjustment should not be
needed when switching between the two.
