Page 4: Installation
Secure the amplifier in the rack with eight screws (not supplied), four in front, four in back. For complete instructions, refer to TD-000050 "Rear Rack Ears Installation Guide" which can be found on the QSC Website (www.qsc.com) CAUTION!!: Be sure that nothing is blocking the front or rear ventilation openings, and that each side has a minimum of 2 cm clearance. - Page 5 — Figure 3 — — Figure 4 — 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.

Screens Channel Configuration Screens Figure 15 is a graphic representations of the amplifier's output CHANNEL CHANNEL CONFIGURATION CONFIGURATION. Inputs (Q) are from Q-SYS, outputs A–D (E–H not shown) represent the amplifier channels and their configuration. Text indicating how many channels, and the output configuration. For possible configurations refer to the Q-SYS help for the amplifier components. - Page 11 LAN A / LAN B Screen LAN A (AUTO) Refer to Figure 18 IP ADDRESS: 192.168.xxx.xxx NETMASK: 255.255.0.0 IP ADDRESS – a default address is assigned in the factory. You can change this GATEWAY: and the other parameters in Q-SYS Configurator. LAN A is required, and cannot be LAN B (AUTO, NO LINK) turned off.
- Page 12 Output Screens OUTPUT Each group of outputs has a dedicated screen. Figure 21 is an example of Outputs A – D. PROTECT LIMIT SHORT 43.05ºC Output channel identifiers A – D and E – H (not shown). PROTECT LIMIT SHORT 42.16ºC DAC – when illuminated, this indicates that the signal to the D to A Converter is larger than can be reproduced and a limiter has been engaged to prevent clipping.
