Using The Onyx 400F Console; Settings - Mackie Onyx 400F Owner's Manual

Using the Onyx 400F Console

The Onyx 400F Console does two things:
1) It lets you adjust master settings for the 400F like
sample rate, etc., and 2) It lets you use the DSP Mixer to
create fi ve pairs of zero latency mixes at the line outputs,
independent of what is being sent to the DAW software
application.
There are six tabs along the top of the Onyx 400F
Console. The fi rst fi ve are used to mix the ten inputs to
the ten outputs from the 400F (eight line outs and two
S/PDIF outs). The last tab contains global settings for the
Onyx 400F.
Note: The Onyx 400F uses 24-bit converters and 24-bit
word lengths. This is fi xed and cannot be changed. If
you want to use 16-bit word lengths for burning a CD,
most DAW applications will convert 24-bit words to
16-bit words by simply truncating (removing) the eight
least-signifi cant bits (LSBs). However, it is best to keep
the bit depth at 24-bits until you are ready to burn the
audio to a CD to retain the highest quality digital audio.

Settings

Click the Settings tab to access and change the
sample rate, clock source, DSP Mixer, Headphone
source, Consumer or Professional mode for S/PDIF, and
Buffer size.
Sample Rate
The Onyx 400F can operate at the following sample
rates: 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, and
192 kHz. Click the desired sample rate or click and drag
the rotary dial to select the sample rate.
You can also select the sample rate
in the DAW application, which means
there are two places where you can
select the sample rate, and it is im-
portant that they match.
