Signal Flow
CXD8.4Q and CXD8.8Q
The CXD8.4Q and CXD8.8Q amplifiers have eight MIC/LINE Inputs and eight amplified Outputs on the rear of the
amplifier. The Inputs and Outputs are not physically (or electrically) connected internally giving you the flexibility to use any
available source in Q-SYS for the amplified outputs, and to route the inputs to any output. The inputs and outputs can be
connected in your Q-SYS design as shown in — Figure 14.
The analog inputs are converted to digital audio in the amplifiers and then routed to the Q-SYS Core via Q-LAN (LAN A,
LAN B). The digital signals are brought into the design via the amplifier's Mic/Line Input component. From the Mic/Line
Input component the signals can be sent anywhere within the Q-SYS system.
In the Q-SYS Core digital signals are sent to the amplifier's Output component and fed from the Q-SYS Core via Q-LAN
to the analog amplified outputs of the amplifier. The Output component can have two to eight outputs depending on the
configuration of the amplifier in Q-SYS Designer. The desired configuration is selected in the Properties menu for that
amplifier. When the amplifier's configuration is changed, all of the outputs are placed in a "mute all" state. You must
un-mute all in the Amp Output component's control panel or on the amplifier's front panel.
CXD8.4Qn and CXD8.8Qn
Refer to — Figure 15
The Qn model amplifiers have no analog inputs. The input signal utilized to drive the amplifier channels must be virtually
wired in Q-SYS Designer. The Qn models have eight amplified Outputs on the rear of the amplifier.
In the Q-SYS Core digital signals are sent to the amplifier's Output component and fed from the Q-SYS Core via Q-LAN
to the analog amplified outputs of the amplifier. The Output component can have two to eight outputs depending on the
