Input and Output Signal Flow
CXD8.4Q and CXD8.8Q
Refer to
Figure 13
The CXD8.4Q and CXD8.8Q amplifiers have eight MIC/LINE inputs and eight (two blocks of four) amplified outputs on the rear of the amplifier. The
inputs and outputs are not physically (or electrically) connected in the amplifier 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 13
.
1. The analog inputs are converted to digital audio in the amplifier
2. The converted audio is then routed to the Q-SYS Core via Q-LAN (LAN A, LAN B).
3. The digital signals are brought into the design via the amplifier's Mic/Line Input component.
4. From the Mic/Line Input component the signals can be sent for processing and can be sent anywhere within the Q-SYS system.
5. In the Q-SYS Core digital audio signals (not necessiarily from the amp's inputs) are sent to the Q-SYS Amp Output component.
6. The digital audio is then sent from the Q-SYS Core via Q-LAN to the amplifier.
7. Digital signals are converted to analog, amplified and sent to outputs of the amplifier.

The Q-SYS Amp Output component can have two to eight inputs/outputs depending on the configuration of the amplifier in Q-SYS Designer. The
desired configuration is selected in the Q-SYS Designer Properties menu for the 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 14
The CXD-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 CXD-Qn models have eight (two blocks of four) amplified outputs on the rear of the amplifier.
1. Digital audio is sent to the Q-SYS Core via Q-LAN (LAN A, LAN B).
2. In the Core, the signals can be sent for processing and can be sent anywhere within the Q-SYS system.
3. In the Q-SYS Core digital audio signals are sent to the Q-SYS Amp Output component.
4. The digital audio is then sent from the Q-SYS Core via Q-LAN to the amplifier.
5. Digital signals are converted to analog, amplified, and sent to the outputs of the amplifier.
The Amp Output component can have two to eight outputs depending on the configuration of the amplifier in Q-SYS Designer. The desired
