About UAD-Xpander

• UAD-Xpander was the world's first ExpressCard audio DSP expansion system for Mac OS X and Windows Vista notebook computers.
• The UAD–Xpander has identical DSP power as the UAD-1 series of desktop products.
• Complete documentation for the UAD-Xpander is included in chapter 10 of the UAD v6.1 Manual.
• This section contains UAD-Xpander support information that is not included in the manual.

All Platforms

• Install the UAD Powered Plug-Ins software before connecting the Xpander hardware.
• The Xpander hardware must be connected and powered up before booting the computer.
• Do not remove the UAD ExpressCard or UAD Link Cable, or power down the Xpander while the Xpander is connected to an active computer unless no UAD clients are running and the ExpressCard is properly powered down. Alternately, simply power down the computer before disconnecting the Xpander.
• If the computer is active and no UAD clients are running, the UAD ExpressCard may be safely removed after powering it down by selecting "Safely Remove Hardware" (Windows Task Bar) or "Power off Card" (Macintosh Menu Bar) before removing it. However, the computer must be rebooted with the Xpander connected in order for the hardware to be recognized again.
• The UAD ExpressCard/34 may be used in an ExpressCard/54 slot.

Windows

• UAD-Xpander runs on windows notebook computers under Windows Vista only (Windows XP does not work with UAD-Xpander on notebook computers).
• UAD-Xpander can be used under Windows XP only on PCIe desktop systems via the UAD-Xtenda adapter (which is no longer available).
• System Sleep is not supported when using UAD-Xpander under Windows. System Sleep should be disabled while the UAD-Xpander is connected.
  • To disable Sleep in Windows: In Control Panel>Performance and Maintenance>Power Options>Power Scheme panel, set the Power Scheme to "Always On”
  • To disable Sleep in when notebook lid is closed: In Control Panel>Performance and Maintenance>Power Options, click the "Change when the computer sleeps" option on the left side of the screen, then select "Never"

Mac

• Some prior "unibody" MacBook Pro systems (e.g., MB470LL/A, MB471LL/A, MB604LL/A) did not support UAD-Xpander with RAM configurations greater than 4GB. This issue is resolved with the latest MacBook Pro firmware available from Apple.
• System Sleep works under Mac OS X. If the machine is put to sleep with the transport running, the UAD plug-ins will typically be disabled several seconds before audio stops. Therefore, a change in the audio may be noticed. Similarly, when the system is awakened, it may take several seconds for the UAD plug-ins to be reinitialized.

Additional Information

• The UAD-Xpander requires UAD v4.7.1 or higher (UAD v5.0.0 or higher is recommended for enhanced ease of use).
• UAD-Xpander cannot be used with desktop computers that have only PCI or PCI-X slots because there is no PCI or PCI-X ExpressCard adapter available.
• The ExpressCard slot on notebook computers is non-latching, so it is possible to accidentally pull the card out.
• Do not bend sharp angles into or otherwise kink the UAD link cable. The cable has a ferrite core and multiple conductors that could be damaged by improper handling.
• The UAD-Xpander contains a UAD-1e card that looks similar to the UAD-1e model for desktop computers. However, the cards are not the same. Do not attempt to install a UAD-Xpander card into a computer slot, or put a UAD-1e into the Xpander chassis. Doing so will damage the cards and/or the computer logic board.
• The PCIe-based UAD-Xtenda was a PCIe to ExpressCard Adapter which enables the UAD-Xpander to also be used on a desktop Mac or PC like any other UAD-1 device.
