To change the UAD Bandwidth Allocation setting:
1. Quit all DAW software and the Console application (UAD hosts must be quit to
change this setting).
2. Open the UAD Meter & Control Panel application (see #2 on
3. Open the FireWire panel by clicking the menu button in the UAD Meter window
) or type
⌘
-F (Mac) or Ctrl-F (Windows) as a shortcut.
4. Change the UAD Bandwidth Allocation setting (shown below) by clicking the up or
down arrows, or click/hold the value for a drop menu..
5. See
"UAD Bandwidth Allocation Notes"
below for more information about this set-
ting.
UAD Bandwidth Allocation Notes
• UAD Bandwidth Allocation values in the table are recommended as starting points
for FireWire bandwidth tuning. Depending on external FireWire hard drive usage
(e.g., how many audio tracks are being streamed), lower values may be needed for
increased FireWire hard drive loads, or higher values can be used for increased
UAD plug-in counts when FireWire hard drive usage is lower. To run more UAD
plug-ins within a DAW, use USB, eSATA, or internal hard drives for audio session
files instead of FireWire drives.
• Apollo has intelligent FireWire bus monitoring. If audio playback is compromised,
a “FireWire Interrupt Detected” dialog appears. If that occurs, decrease the UAD
Bandwidth Allocation setting for reliable playback. Note that even if the dialog ap-
pears during playback, audio file integrity is never compromised during recording.
• The UAD Bandwidth Allocation only applies when UAD plug-ins are used within
a DAW. UAD plug-ins do not consume any FireWire bandwidth when used within
Console, nor when connected to the host computer via Thunderbolt.
• (Mac) FireWire performance is better on some systems versus others due to the
FireWire controller chips they contain. In general, newer Mac Pro, iMac, and Mac
mini systems contain a superior FireWire controller chip and will deliver better
FireWire performance than MacBook Pro systems. There is no simple method to
determine which controller is used.
