If the host computer has multiple FireWire buses (this is rare), up to two speeds
will be displayed, with the values separated by a comma.
Note:
If the host computer supports FireWire 800 and the Target Link Speed
is set to 800, but the Current Link Speed still displays 400, check the bus or-
dering of the FireWire devices. See
“Mixing FireWire Speeds” on page 140
for information on how to properly combine FireWire 400 and FireWire 800
devices on the same bus.
Target Link
Speed
The desired speed of the FireWire link between the host computer and the
UAD-2 Satellite is set here (the actual link speed is shown in the
display). To change the value, click the down arrow to display the
drop menu, then select the desired value. The setting cannot be changed
when UAD plug-ins are loaded.
Target Link Speed should be set to 800 when supported by the host computer.
However, some FireWire devices may not always perform flawlessly. Chang-
ing the Target Link Speed to 400 may actually improve performance and/or
stability on systems not optimized for FireWire 800 operation.
Tip:
Twice as many UAD-2 Satellite plug-ins can be run at 800 versus 400,
so configure the FireWire system to run at 800 if supported by the computer.
UAD Bandwidth
Allocation
This parameter determines how much of the total available FireWire bus
bandwidth will be reserved for UAD-2 Satellite plug-ins. Limiting the band-
width used by UAD-2 Satellite ensures that other FireWire devices on the
same bus will have enough bandwidth to function properly.
To change the value, click the increment/decrement arrows, click/hold the
current target value to display a drop menu, or double-click the value for di-
rect text entry. The maximum available value is 85%.
Note:
The value cannot be changed when UAD plug-ins are active.
Although the amount of FireWire bandwidth reserved by UAD-2 Satellite de-
pends on the UAD Bandwidth Allocation setting, the amount of DSP used by
any UAD plug-in does not affect FireWire bandwidth (UAD plug-ins that use
very little DSP require the same FireWire bandwidth as DSP-intensive UAD
plug-ins). See
