The Configuration Panel is where most of the global UAD settings and preferences are
specified for all UAD devices.

DSP Load Limiting Overview
The UAD DSP can be limited so the load cannot exceed 100%, thereby increasing over-
all system stability in high load situations. With very heavy UAD loads, DSP load limiting
may also improve host CPU performance.
There are many variables that affect UAD DSP load (sample rate, buffer size, parameter
values, mono/stereo, automation, host system, etc). Although these variables are taken
into account, the resulting measurement cannot be absolutely accurate. This is due to
variations in system configurations, specifically PCI/PCIe bus loading which is impossible
to predict.
Systems that are heavily loaded due to the presence of other devices or suboptimal con-
figuration may cause additional DSP loading that cannot be predicted by the UAD plug-
in load calculator. The DSP load limit should be reduced in this case.
It is possible for certain (non-typical) conditions to be met where another UAD plug-in
can’t be added, even when the UAD Meter says you should have DSP available when
compared to the DSP Load Limit value.
