Input and Output Signal Flow
DPA-Q Series Amplifiers
Refer to Figure 14
The DPA 4K8Q and DPA 8K8Q amplifiers have eight MIC/LINE inputs and eight (two blocks of four) amplified outputs on the rear of the
amplifier. The DPA 2K4Q, DPA 4K4Q, and DPA 8K4Q amplifiers have four MIC/LINE inputs and four (one block 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 14.
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 necessarily 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.

Inputs
The Q-SYS Amp Output component can have one to eight inputs/outputs depending on the amplifier model and its configuration 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 can un-mute all by clicking the Mute All button in Q-SYS Designer's Amp
Output component or press and release the Amplifier Mode button on the amplifier's front panel.

Refer to Figure 15
The DPA-Q model amplifiers have no analog inputs. The input signal utilized to drive the amplifier channels must be virtually wired in

Q-SYS Designer.
1. Digital audio is sent to the Q-SYS Core via Q-LAN.
2. In the Core, the signals can be processed and 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.
