LAN A / LAN B Screen
Refer to Figure 18
IP ADDRESS – a default address is assigned in the factory. You can change this
1.
and the other parameters in Q-SYS Configurator. LAN A is required, and cannot be
turned off.
NETMASK – must be the same as the Core's Netmask.
2.
GATEWAY – must be the same as the Core's Gateway.
3.
LAN B is not required. When connected, the same type of information as LAN A is displayed.
4.
Health Screen
Refer to Figure 19
FAN RPM – varies depending on the temperature.
1.
PSU TEMP – varies depending on operating conditions. PSU Temp is monitored
2.
and can automatically put the amp into limiting or shutdown if safe operating
temperatures are exceeded.
AC VOLTAGE – AC Mains voltage
3.
AC CURRENT – AC mains current drawn by the amplifier.
4.
5. Voltage Rails
• V RAIL 1 = +147VDC +/- 5V typical
• V RAIL 2 = -147VDC +/- 5V typical
OUTPUT GAINS Screen
Refer to Figure 20
The Output Gain screens provides a quick overview of all outputs. In addition, when this
screen is displayed, you can make GAIN adjustments on the amplifier's front panel. There is
one screen for channels A–D and one for channels E–H.
Use the NEXT or PREV buttons to access these screens or, press one or more of the SEL
buttons to access the screen.
1. The highlighted background indicates that the Channel is selected by the SEL button.
Channel – the channels display according to the configuration of the amplifier.
2.
Output Gain – the output gain can be controlled in two places: the GAIN knob on
3.
the amplifier front panel and with the Gain control in the amplifier's Output component
in the Q-SYS design.
Q-LAN Input Level – the level of the audio signal applied to the Output component in the Q-SYS design. The CXD-Q Output component is
4.
the connection to the output section of the amplifier.
VOLTS – the voltage applied to that output.
5.
6. Output B is combined with Output A – (AB or A+B), the slot for Output B is blank.
To Make Gain Adjustments:
a. Use the SEL button to select one or more channels. You can select any or all channels.
b. Use the GAIN knob to make adjustments on the output gain of the selected channels.
NOTE!: If the gains were the same when you select multiple channels the gains remain equal as you adjust them. If the gains are
different, they keep their relative separation until one reaches a limit. At this point the other channel(s) continue to change until they
reach the limit.
NOTE!: If you press one or more of the SEL buttons, and do not make any GAIN adjustments, this screen remains visible for a short
time then returns to the previous screen.
