UAD Powered Plug-Ins Manual - 52 - Chapter 5: Using Multiple UAD Cards
Important: If insufficient power is available to the UAD cards, unpredict-
able behavior may result.
Windows The PCI specification provides for up to 25W per device, however some host
systems don't provide (or require) this much power. When designing a com-
puter DAW system, a common rule of thumb is to provide an extra
50%–100% of headroom over the estimated maximum total power draw of
all components in the system. Don’t skimp on the power supply unit! When
building a custom system a quality sufficiently-rated PSU is critical for system
stability.
Multicard DSP Loading
DSP loading in a multicard system behaves the same as in a single UAD-2
Duo or Quad system, and is managed automatically by the UAD software.
See “DSP Loading Information” on page 80 for details.
Card Info Display
UAD DSP and memory resources used for each installed card, and the ability
to enable/disable individual cards, is displayed in the System Information
window. See “System Information Panel” on page 58 for complete details.
Disabling Cards
Individual UAD cards can be disabled using the Card Enabled function (see
page 60). This can be useful, for example, if creating a session on a system
with multiple cards that will be transferred to a system with fewer cards.
Cards are disabled only while the UAD Meter & Control Panel application
open. When the UAD Meter & Control Panel is quit, disabled cards are re-en-
abled.
