MAKING SETTINGS IN THE MOTU FIREWIRE
AUDIO CONSOLE
Before you run your audio software, launch the
MOTU FireWire Audio Console to configure your
896HD hardware. The MOTU FireWire Audio
Console lets you choose the audio clock source,
and it lets you enable the optical input and output,
if needed. For details, see chapter 5, “MOTU
FireWire Audio Console” (page 35).
Figure 7-1: The MOTU FireWire Audio Console gives you access to all
of the settings in the 896HD hardware, including the clock source,
sample rate and optical I/O enable/disable.
For complete details about the 896HD settings, see
chapter 5, “MOTU FireWire Audio Console”
(page 35). The following sections provide a brief
explanation of each 896HD setting for use with
Sonar.
Sample rate
Choose the desired overall sample rate for the
896HD system and Sonar. Newly recorded audio in
Sonar will have this sample rate.
Before running the 896HD at the 4x sample rates,
see “Operation at 4x sample rates (176.4 or
192kHz)” on page 36.
Clock Source
This setting is very important because it
determines which audio clock the 896HD will
follow.
If you do not have any digital audio connections to
your 896HD (you are using the analog inputs and
outputs only), and you will not be slaving Sonar to
external SMPTE time code, choose
Internal .
If you are slaving the 896HD to the ADAT Sync or
Word Clock input connector, choose
ADAT 9-pin
or Word Clock In , respectively.
For information about the other clock source
settings, see “Clock Source” on page 37.
If you have digital audio devices connected to the
896HD, see “Making sync connections” on
page 21.
Samples Per Buffer
The Samples Per Buffer setting can be used to
reduce the delay — or monitoring latency — that
you hear when live audio is patched through your
896HD hardware and Sonar. For example, you
might have MIDI instruments, samplers,
microphones, and so on connected to the analog
inputs of the 896HD. If so, you will often be mixing
