The HP Filter controls drive the channel high pass filter at the input of the crossover (see figures 4 and 5). 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.

Logging Tab
The JSD-100MA includes extensive logging. The left side of the screen shows the GUI log. It shows GUI activity,
such as connections to JSD-100MA units and other activities. The right side of the screen shows the Unit Log
for the specific JSD-100MA.
The JSD-100MA 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-100MA.
