The MIOConsole3d Application

Once you have selected the desired Unit, use the
“Source”
menu to choose a clock source from the digital
ports available on that box.
Each box in your domain may have an different set of digital inputs from which to choose, so the
Source
menu will vary from box to box.
All 3d boxes have a Word Clock input. All ULN-8s and LIO-8s have 8-channels of AES I/O built-in. All 2882s
and ULN2s have ADAT/TOSLINK optical digital I/O built-in, with ‘SPDIF • AES’ EdgeBus cards included by
default (unless you ordered a different card). The list of available clock sources in the
Unit Clock “Source”
selector
will also include the digital ports of any EdgeBus card you have installed. The example below
is a stock LIO-8 with a ‘SPDIF x2 • ADAT x2’ EdgeBus Card, so it lists word clock, the four built-in AES
channel pairs, plus the two ADAT optical and SPDIF RCA digital ports on the EdgeBus Card as available
clock sources.

When you have selected an external clock source, the
“Domain Master Clock Source”
selector will change
from ‘Internal’ to display the digital audio clock source from which the Domain is now clocking. This will
include the box model and serial number, and the port on that box receiving the master clock signal.
Figure 10.71: Domain Master Clock Source display: set to external
In the example above, your new Domain master clock source is from the EdgeBus card SPDIF port 1 on
LIO-8 sn40109, and it is running at 48kHz (per the "Sample Rate Selector / Display", detailed in the next
entry).
Sample Rate Selector / Display
The
"Sample Rate Selector / Display"
(located to the immediate right of the “Domain Clock Source Selector”)
will always display the current Domain sample rate.
In the example below, the screenshot on the left shows the “Domain Clock Source” set to ‘Internal’, with
the sample rate set to 96kHz. The screenshot to the right shows the system slaved to an external clock
source, which is naturally controlling the sample rate for the Domain.

Note the up/down arrows next to the sample rate selector when set to ‘Internal‘ - this indicates the selector
is live and in control of the sample rate.
