Helix Board Control Panel
The Helix Board FireWire control panel can be accessed at
any time by entering choosing the shortcut from your Programs
menu. This program will not only allow users to alter their device
and channel names and properties, but will also let them correct
for latency issues, change sampling rates, and so forth. When
opening the software, a number of options will be available for
users to select from, allowing them to adjust the available prop-
erties.
Devices
In the Devices section, users are able to view and edit the name
of the Phonic FireWire Devices connected to their computer.
Input Channels
The Input Channels section allows users to view and edit the
name of the various input channels received from the FireWire
input. For a list of default channel names, please consult the
table on page 16.

Output Channels
By entering the Output Channels section, users can view and
edit the names of the two output channels from the computer to
the Helix Board 18 FireWire MKII mixer.
Synchronization
In the Synchronization section, users can adjust the sampling
rate and other synchronization properties. Many of these adjust-
able properties, as they are, are set for optimum performance
and, unless you are sure of what you need to change, are prob-
ably best left alone.
First off, the synch mode can be altered, though making this al-
teration is not recommended for novice users. The synch mode
is basically the way the computer determines what the 'clock
source' (ie. device that your computer will use to determine the
timing of all digital signals received) will be. The default setting
for this feature is "CSP", meaning the Helix Board 18 FireWire
MKII is the "master" clock source of the device. The other op-
tions allow users to make the Helix Board 18 FireWire MKII fol-
low the "timing" of whichever device is the clock source. Having
two clock sources has the potential to create very undesireable
audio, so it is best avoided. If the Helix Board 18 FireWire MKII
is the only piece of digital audio equipment attached to the com-
puter, there is no reason this option should be changed.
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 .
