Users are also able to change between automatic and
manual sampling rate settings. W hen 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. M any 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
Settings section.
The Stream Buffer Depth is adjustable between 0.5
and 20 milliseconds. It adjusts the buffer used when
streaming a signal from the Helix Board 12 FireWire.
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
The WDM (Windows Driver Model) Sound Buffer
Depth is adjustable between 4 and 40 milliseconds.
This allows 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
connection has been interupted can be viewed.

Streams
In the Streams section, the Helix Board 12 F ireWire
device 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.
