Inputs
Connect the amplifier LAN A, and if available, LAN B, to the Q-LAN network (Figure 4). Refer to your Q-SYS documentation for network
requirements and connection detail.

The analog inputs are converted to digital audio in the CXD8.4Q and
CXD8.8Q amplifiers and then routed to the Q-SYS Core over the network.
The digital signals show up in Q-SYS Designer at the CXD-Q input
component where they can be routed as needed. Refer to the Q-SYS
documentation.
1. Make sure your audio source devices are powered off.
2. Wire the audio mic- or line-level source to up to eight Euro-style
connectors (supplied), you can use either balanced inputs (Figure 2)
or unbalanced inputs (Figure 3).
3. Plug the connectors into the appropriate receptacles (Routeable
Inputs 1, 2, 3, 4, 5, 6, 7, 8) Figure 4 and Figure 5.
GPIO
Refer to "GPIO" on page 13 for details about the GPIO feature.
Outputs and Output Configuration
The CXD-Q amplifiers have two sets of four-channel outputs that are configured independently. The configuration of the amplifier is defined in
Q-SYS designer software and is "pushed" into the physical amplifier when the Name and Type of amplifier in the design matches the Name and
Type of physical amplifier. When the output configuration of the amplifier changes, the Outputs to the loudspeakers change accordingly.
Use the diagrams shown in Figure 6 thru Figure 9 as a reference for planning your loudspeaker configuration. Refer to Figure 10 for how to
connect the wiring based on your configuration. After connecting the loudspeakers to the outputs, you may turn the amplifier on.
CAUTION!!: Before turning the amplifier on, double check your output connections to be sure they are connected properly based
on the output configuration specified in Q-SYS Designer.
If you change the output configuration of the amplifier you must change the loudspeaker connections before applying power to the
amplifier!
After a change of the output configuration, the amplifier re-boots and all outputs are muted. You must press the Mute All button in the
Q-SYS Amp Output component, or unmute all channels on the front panel of the amplifier.
Figure 6 thru Figure 9 are examples of the three types of output configurations: Separate, Bridged and Parallel. The tables to the right and left
of the loudspeaker connections (rear panel of the amplifier) give all the possible configurations and their connections.
