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-100 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-100 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.
The HP Filter controls drive the channel high pass filter at the input of the crossover (see figures 4.2b and 4.2c).
This filter limits the extremely low frequency output for the channel, but can also be used to apply a low frequency
peak by increasing the Q above 0.707.
The filters in each crossover band are
described in section 4.2. Note that
frequencies are in Hz, gains in dB, and
delays in ms. The filter types are
abbreviated as LP for Low Pass filter, HP
for High Pass filter, PEQ for Parametric
EQualizer, HEQ for the high frequency
Horn shelf EQualizer, and SEQ for the high
frequency Screen shelf EQualizer.
The Mute and Invert buttons mute a
particular band output or invert the phase.
The figure above shows the "crossover"
settings for an LFE output. Depending on the output module type, one or more LFE outputs are available. Each has
a separate parametric equalizer that can be adjusted on this screen. Similarly, Ls and Rs may have multiple outputs
and separate delay controls for each.
Note that the filter plot of the LFE channel includes the effect of the 125Hz
low pass filter specified for the LFE channel in SMPTE EG0432-2-2006.
7.4.6.8 Logging Tab
The JSD-100 includes extensive logging. The
left side of the screen shows the GUI log. It
shows GUI activity, such as connections to
JSD-100 units and other activities. The right
side of the screen shows the Unit Log for the
specific JSD-100.
The JSD-100 holds a log of the last 32,768
events. Events include level changes, format
changes, remote connections by the GUI or
other devices, etc. Press the Get Latest
button to get the 100 most recent log entries.
Press the Get All button to get the full log from the JSD-100.
