Page 9 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. DPA8.4Qn and DPA8.8Qn Refer to Figure 14 The DPA-Qn model amplifiers have no analog inputs.
Page 10 Screens Channel Configuration Screens Figure 15 is a graphic representation 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.
