Input and Output Signal Flow
The CXD-Q amplifi ers have four Mic/Line Inputs and four amplifi ed Outputs on the rear of the amplifi er. The Inputs and Outputs on the rear of the
amplifi er are not connected inside the amplifi er.
The analog inputs are converted to digital audio in the amplifi er (1) and then routed to the Q-SYS Core via Q-LAN (LAN A, LAN B) (2). The digital
signals are brought into the Q-SYS design to the CXD-Q Amplifi er Input component (3). From the CXD-Q Input component the signals can be sent
DSP in the Core (4), and routed anywhere else within the Q-SYS system.
Likewise, in Q-SYS Designer digital signals are received at the CXD-Q Output component (5) and fed from the Q-SYS Core to the amplifi er via Q-LAN
(6), converted to analog signals and then to the amplifi ed outputs of the CXD-Q (7). The CXD-Q output component can have one to four outputs
depending on the confi guration of the amplifi er. The desired confi guration is selected in the Q-SYS Designer properties menu for that amplifi er.

1. Graphic representations of the amplifi er's output confi guration. Inputs (Q) are from Q-SYS,
outputs (A-D) show the amplifi er channels and their confi guration.
2. Text indicating how many channels, and the output confi guration. For possible
confi gurations refer to the Q-SYS help for the CXD-Q Amplifi er component.
3. Status of the amplifi er and Q-SYS design indicating the design and amp are in sync.
4. Status of the amplifi er indicating that action is necessary to synchronize the design
and amplifi er.
5. Action you need to perform to change the amplifi er confi guration. Press the ID button to
the right of the message.
Status Screen
Refer to Figure 16
1. DEVICE: This is the hostname (network name) of the amplifi er. A default name is given at the factory, similar to the example. You may change the
name in the Q-SYS Confi gurator.
2. DESIGN: This is the name of the Q-SYS design containing the amplifi er. The amplifi er must
be in a running design to operate.
3. STATUS: Displays the current status of the amplifi er both in text and color. The following is
a list of possible status colors, and some example conditions.
• OK – Green – Audio is good, hardware is good.
• Compromised – Orange – Audio is good but a redundancy mechanism is active (one
LAN down but the other is still up) or a non-fatal hardware problem exists (fans too
slow, temperature higher than expected, etc.)
• Fault – Red – Audio is not passing, or hardware is malfunctioning or mis-confi gured
(amplifi er power off, audio streams broken, amplifi er fault, loudspeaker short circuit, etc.)
• Initializing – Blue – In the process of initialization, and design start. Audio is not passed.
