Tascam US-224 owner manual Installation, System Requirements

3. Installation

3.1 System Requirements

PC: Minimum requirements: Pentium II - 266 MHz (or equivalent) processor running Windows 98 (Second or Millennium Edition), Windows 2000 or Windows XP, 96MB RAM. Recommended: Pentium II 300MHz processor with 128MB RAM or better. (These requirements are for use with Cubasis VST. Other applications will have different requirements. Consult your application's manufacturer for further information.)

NOTE: The US-224 is not supported under Windows 95. We also do not recommend Windows98 First Edition, due to its limited USB implementation. A fast EIDE hard disk is required for throughput of multiple audio tracks. 96MB RAM is the minimum recommended, but with all digital audio programs, you’ll have better results with more RAM. An SVGA graphics card is suggested (min. 256 colors, 800x600 resolution or better).

Although this product has been checked for use with standard configuration computers which meet the specifications above, we cannot guarantee the operation of the product, even with computers meeting the specifications, due to differences in architecture and implementation between computers.

Chipsets are also a concern with USB audio. We’ve found that the most dependable motherboards are ones which utilize Intel- based chipsets. You can determine your chipset by going into the Device Manager. On the Windows 98 desktop, right click on My Computer, and select Properties. Click on the Device Manager tab, and then click on the plus (+) sign next to Universal Serial Bus Controllers. (see illustration 3.01)

Illustration 3.01 - Determining your USB Controller

The following chipsets have been successfully run with the US-224:

Intel 82371 AB/EB PCI to USB Universal Host Controller

Intel 82371 SB PCI to USB Universal Host Controller

Intel 82801 AA PCI to USB Universal Host Controller

ALi PCI to USB Open Host Controller

Some other chipsets, notably those specifying Open Host Controllers or OHCI (rather than Universal Host Controllers or UHCI), have been subject to occasional incompatibilities. While most OHCI systems have no problems with the US-224, occasionally some older OHCI systems will exhibit problems. We have found that, in the majority of these rare cases, a PCI-based USB card utilizing an Opti-chip controller will work dependably. These cards (also available in PCMCIA format for laptops) are available through a number of manufacturers. Please consult the TASCAM website for further information.
