UAD Powered Plug-Ins Manual - 51 - Chapter 5: Using Multiple UAD Cards
However, as an example, if you have four UAD cards but run a dual-card sys-
tem in two separate computers, you are required to purchase separate li-
censes for the second system.
Authorizing Multiple Cards
When you buy an optional plug-in, your purchased license is valid for all the
cards in the computer. The license is tied to the specific UAD cards in the Sys-
tem (see page 44) when the license was purchased. For example, if you have
two cards when you purchase a plug-in, your authorization file will authorize
both cards.
If you have one card during purchase then later acquire another card(s), you
will need to download a new authorization file containing the licenses for the
new card(s). However, there is no charge for the new authorization file con-
taining the additional licenses. Your purchase buys licenses for all the cards
in the same computer.
Each individual card must be authorized in order to run optional plug-ins,
however multiple installed cards are authorized simultaneously. If one card is
authorized then another card is added without downloading a new authori-
zation, the optional plug-in will only load on the previously authorized card.
To obtain a new authorization file for additional cards, use the “Authorize
Plug-ins...” button (page 61) in the UAD Meter & Control Panel.
Power Requirement
Each UAD card draws power from the expansion slot bus that it is installed in
(PCI, PCI-X, or PCIe). The total power draw of all the installed cards must not
exceed the power that can be adequately delivered by the host computer.
The UAD card power requirements are listed in Table 2 on page 52. These
figures are measurements of the actual power draw for these devices when
running at full DSP load.
IRQ Conflicts Under rare conditions running multiple UAD cards may cause an IRQ conflict
which can cause system instabilty or freezes. If this occurs, try moving the
UAD card(s) to different slots and/or contacting UA for technical assistance.
