Users are also able to change between automatic and
manual sampling rate settings. When the sampling rate is
manually set, users can select between sampling rates of
44.1, 48.0, 88.2 and 96.0 kHz per second. Many devices
have sampling rates that do not surpass 44.1 kHz per
second, therefore, when using multiple digital devices,
users are advised not to exceed this level unless they are
sure the secondary device's sampling rate can .
Settings
Users are able to adjust various buffer times in the Set-
tings section.
The Stream Buffer Depth is adjustable between 0.5 and
20 milliseconds. It adjusts the buffer used when stream-
ing a signal from the Helix Board 18 Universal. If the depth
is set too high, an obvious latency will become evident. If
the depth is too low, various clicks and pops may become
obvious. It is best to set the Stream Buffer Depth to a
level that allows users to get the lowest latency, while still
maintaining an optimal performance. The default settings
are ideal for most computers.
The ASIO Buffer Depth is adjustable between 4 and 40
milliseconds. This allows users to adjust the latency of
the stream received by ASIO driver-based software (in-
cluding Steinberg Cubase LE).
The WDM (Windows Driver Model) Sound Buffer Depth
is adjustable between 4 and 40 milliseconds. This al-
lows users to adjust the latency of the stream received by
WDM based programs.
Also in this section, users are able to view their "drop out
statistics", where the number of times the FireWire / USB
connection has been interrupted can be viewed.

Streams
In the Streams section, the Helix Board 18 Universal de-
vice properties can be viewed. Each input and output
stream can be scrutinized, and the isochronous stream
number and its supported sampling rates can be viewed.
