Global Mixer
Groups A-D These mix-minus buses are defined as microphone mixer groups which support
first-mic priority, maximum number of mics, etc. and work across all linked XAP 800s. Unlike the audio buses,
they contain only mic status and gate parameters. All mics are assigned to the A mixer group by default.
P
A Adapt/Acoustic Echo Cancellation Reference Buses E1-E4 Allows an input from a XAP 800 to reference
an output on another linked XAP 800. See PA Adapt and AEC Reference on page 43 for more information.
Control Link
The control bus is an independent link from the E-Bus’s audio link; it uses a different pair of wires on the same
E-Bus cable. This allows control information to pass even if the boxes are not using the audio link. The XAP
800 supports the full set of commands through the control link.
Network Requirements
The Expansion Bus (RS-485 LAN) lets you connect up to eight XAP 800s. The maximum distance between
interconnected Gentner units is 80 feet (24 meters). Gentner recommends that category five twisted-pair
(10BaseT) cable be used.
Equipment Placement
The XAP 800 is designed to mount in a 19" (48.26cm) equipment rack. Do not block the ventilation holes.
With a desktop kit, it can be adapted for tabletop use.
Environmental Requirements
The XAP 800 can be safely operated in a room with temperatures between 32° F (0° C) and 110° F (43° C).
