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)
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.
