UAD System Manual - 67 - Chapter 6: UAD Meter & Control Panel
Tip: If FireWire performance issues occur, leave a bit of unused FireWire
bandwidth (headroom), so the total usage for all devices is less than 100%.
To leave 5% of the bandwidth available for headroom in the example above,
you’d enter 75% for UAD Bandwidth Allocation (20% bandwidth without
UAD-2 Satellite + 75% for UAD-2 Satellite = 95% total FireWire bandwidth).
This is especially applicable if using FireWire hard drives on the same bus for
audio session data.
Plug-In
Calculator
The Plug-In Calculator displays the maximum number of stereo UAD plug-ins
that can be run on UAD-2 Satellite and Apollo with the current FireWire Sys-
tem settings at a given sample rate.
Note: The Plug-In Calculator is for informational purposes only; it does not
actually affect UAD FireWire or DSP performance in any way.
Max Stereo Plug-Ins
The maximum number of stereo UAD plug-ins that can run on UAD-2 Satellite
and Apollo, based upon the FireWire System settings and a given session
sample rate, is displayed here. The number changes if/when session sample
rate changes.
The UAD instantiation count at the current settings could exceed this number
If used in true mono configurations. Note that some DAWs use stereo plug-in
processing even when used on a mono audio file.
At the following sample rate
This parameter selects the sample rate used by the Plug-In Calculator. To
change the value, click the down arrow to display the drop menu, then select
the desired value.
When a UAD plug-in is loaded by the host software, the session sample rate
is entered automatically. In this scenario, the parameter cannot be modified
until the host is quit.
Note: The “At the following sample rate” parameter is only used by the
Plug-in Calculator; it does not affect the actual sample rate of the UAD system
or the host software.
Bandwidth
Metering
Bandwidth Metering pertains to the FireWire bus that UAD-2 Satellite and
Apollo are attached to. The items displayed in this area are for informational
purposes only; there are no settings here that can be changed.
