UAD Powered Plug-Ins Manual - 94 - Chapter 7: Using UAD Powered Plug-Ins
UAD Devices
with UAD-2
Satellite
Because Firewire has significantly less bandwidth than the PCIe protocol, if
UAD-2 Satellite is running with UAD-2 PCIe card(s) in a multidevice system,
UAD plug-ins will load on the UAD-2 card(s) before the Firewire device in or-
der to maximize Firewire bandwidth. See “FireW
ire Bandwidth vs. UAD
DSP” on page 143 for more information UAD-2 Satellite loading.

Notes
• UAD DSP usage is proportional to the host application sample rate and sys-
tem PCI/PCIe bus speed. Therefore, more plug-ins can be used simulta-
neously in a 44.1K session than in a 96K session, and likewise a higher
speed bus will use less DSP load than a slower bus.
• Bypassing individual components will conserve DSP on some UAD plug-ins.
For example, bypassing the compressor in the EX-1 when only the EQ is in
use, and/or bypassing any of the unused bands of the EX-1 EQ will use less
UAD DSP
.
• The UAD DSP resources required by each successive UAD Powered Plug-In
instance will slightly decrease.
• A chart showing expected plug-in counts can be found on our website:

Host CPU Loads • The host system memory and CPU are never used for Powered Plug-Ins pro-
cessing. However, there will always be a small amount of load on the host
CPU induced by data transfers and user interface operations. This is un-
avoidable when using any DSP device.
• When LiveTrack Mode is active, host CPU load is increased. See “LiveT
rack
Mode” on page 89 for details.
Automation
Every UAD Powered Plug-In parameter can be automated if this feature is sup-
ported by the host application. Each host application has its own particular
methods for automation. Consult the host application documentation for spe-
cific instructions on using automation with the application.
UAD Powered Plug-Ins reduce their DSP load when bypassed or disabled, but
not their memory load. This feature allows for automatable load balancing of
DSP power, and keeps the track delay constant to avoid on/off clicks.
Note: If there is not enough DSP available when automating, the plug-in may
not turn on. When this occurs, “DISABLED” is displayed in the UAD Toolbar.
