NOTE
: This section does not apply to Mac OS X, and will not appear if you are running
that operating system. Mac OS X does not support ASIO (or WDM).
Bit Depth
– This field will only appear in Mac OS 9 installations. The selections from this
drop-down list will be 16-bit, 24-bit, or auto. Some music programs in OS 9 will not work
properly with 24-bit audio, in which case your bit depth setting will either a) switch
automatically to 16-bit, or b) require that you manually set the bit depth setting in your
FireWire Audiophile Hardware page to 16-bit. Otherwise, leave your bit depth set to
“auto,” which is the default setting. It is also possible that slower CPUs may benefit from
a lower bit depth setting, so if your machine seems to be having a hard time handling the
audio processing, try the 16-bit setting.
Sync Source
– This field allows you to choose between the FireWire Audiophile’s
internal
clock and an
external
clock source.
Internal
selects the incoming clock from
the FireWire bus as set by your audio software. Use
external
when you wish to record
from the S/PDIF inputs, or otherwise lock to the sample rate from an external S/PDIF
source.
HP (Headphone) Source Settings –
This field allows you to choose the operational
mode of the front panel HP Source switch. You can choose between the four radio
buttons in the “A” column, and between the four radio buttons in the “B” column. The HP
Source will reflect the selections made here in the Control Panel, and the front panel HP
Source LED will indicate the current source selection, A or B.
Momentary Switch Settings
– This field allows you to change the assignment of the
front panel HP Source Settings momentary switch, toggling between the above
“Headphone Source Settings” or “Direct Monitoring On/Off” setting. When Direct
Monitoring is selected, the front panel HP Source switch will enable and disable Direct
Monitoring. (See the section, Using Your FireWire Audiophile for more information.)
