the X-Array™loudspeaker systems. Digi- tal parameter settings for both controllers are available upon request.
Electrical Connection and System Wiring
Two paralleled Neutrik 8-pin Speakon® con- nectors are used for electrical connection to the Xds loudspeakers with the following pin assignments:
SUB1: Pins 1 Paralleled
SUB2: Pins 2 Paralleled
The Xds wiring diagram is shown in Figure
7.Since the connectors are paralleled, it does not matter which connector is used as the input or output when paralleling Xds sys- tems. Although Pins 3 and 4 are not used by the Xds systems, they are paralleled on the input panel. This allows an X-Array™MB/ HF box (like the Xf or Xcn– which use Pins 3 and 4, but not Pins 1 and 2) to be paral- leled with an Xds, allowing all eight con- ductors to be used with a single cable run to the amplifiers. Note that, when two Xds sys- tems are jumped from one to another via the input/output connections, the amplifier home run cable will have two woofers on Pins 2 (for a 4-ohm load) and two woofers on Pins 1 (for a 4-ohm load).
Field Replacement
Normal service for the Xds requires only a #2 Phillips screwdriver and a 3/16-inch hex- key wrench. The drivers may be accessed as follows:
SUB: First remove the grille, then remove the screws securing the hatch on the front of the enclosure. Remove the screws securing the 18-inch woofer and lift the woofer out of the enclosure. In the event of failure, the entire woofer must be replaced or reconed.
The following service parts are available from the service department in Buchanan, Michigan USA:
