UAD System Manual - 78 - Chapter 7: Using UAD Powered Plug-Ins
DSP Loading Information
The UAD devices feature either one (UAD-2 SOLO), two (UAD-2 DUO), four 
(UAD-2 Quad), or eight (UAD-2 OCTO) on-board SHARC DSP chips for pro-
cessing UAD Powered Plug-Ins.
Multi-DSP UAD-2 systems use sophisticated load balancing routines. UAD-2 
plug-ins are always allocated as efficiently as possible, which is not necessar-
ily on the DSP with the lowest resource usage.
UAD FireWire 
Devices
Because Firewire has significantly less bandwidth than the PCIe protocol, if 
UAD-2 Satellite and/or Apollo is running with UAD-2 PCIe card(s) in a multi-
device system, UAD plug-ins will load on the UAD-2 card(s) before the 
Firewire device in order to maximize Firewire bandwidth. See “FireWire 
Bandwidth vs. UAD DSP” on page 111 for more information.
