XO, Etc. Tab
The XO, Etc. Tab is used to configure crossovers and other outputs where a single channel drives multiple
outputs (see section 4.2 for block diagrams showing crossovers and other outputs).
This section describes the display and controls of this tab.
Along the top of the XO, Etc. Tab display are buttons that select which channel the current display applies to.
Note that all channels are listed, including those where no crossover controls are available. If a channel
without crossover controls is selected, the controls will be "grayed out."
The View button toggles the graph between a view of the filter frequency response and the RTA display.
You can watch how the controls affect the filters within the JSD-100MA or how they affect the sound in the
auditorium. If an external pink noise generator is to be used with the internal RTA, enable the internal pink
noise generator, then disable it. Enabling the internal pink noise generator configures the internal RTA for
proper operation.
The Speaker button opens a file select dialog where you can select a speaker from the speaker library. This
loads all the crossover settings with values appropriate for that speaker. Depending on the system
configuration (as set by the Channel Config button at the top of the JSD-100MA screen), the appropriate
library (biamp or triamp) is opened. Once a speaker is selected, you can select which screen channels to apply
these crossover settings to.
The Copy button allows you to copy the crossover settings from one channel to one or more additional
channels.
The Zoom slider changes the number of dB per vertical grid line on the graph. This control is only visible when
viewing the filter response, not the RTA.
The Bypass button is only visible when the RTA view is selected. When Bypass is enabled, the JSD-100MA
outputs are switched from the normal processed outputs to the bypass outputs. This allows viewing the RTA
output while in bypass so the bypass crossover can be adjusted.
