on page 56. After reading this section you should have a feel for how to
apply Mobile I/O’s routing and mixing capabities.
In this configuration Mobile I/O is connected to an external preamp/con-
verter via ADAT Optical. This gives a total of 16 analog inputs. All of these
are available for mixing with the WIDE mixer.
W HICH DEVICE IS THE C LOCK M ASTER
The first consideration involved with a setup like this is which device should
be the clock master. If the external device is happy slaving to Mobile I/O
then make Mobile I/O the clock master by setting the clock source to inter-
nal in MIO Console. Set the external device to lock to ADAT Optical, or
wordclock if the external device has a wordclock input. If you use word-
clock, make sure to connect a 75 Ohm BNC cable between Mobile I/O and
the external device.
If you find that you are getting clicks and pops in the audio coming from the
external converter, try clocking in the other direction. Set the external con-
verter to use its internal clock and set the Mobile I/O clock source to ADAT.
Remember to choose the appropriate clock rate (single or double) for the
sample rate you will be working at.
Once you have Mobile I/O and the external converter locked you should be
able to get the AES effects device to lock to Mobile I/O’s AES signal, regard-
less of whether Mobile I/O or the external converter is the clock master.
Now that all of the digital devices are playing nicely with each other, let’s
take a look at some possible applications with this setup.
E FFECTS FOR T RACKING
Many performers (especially singers) find it easier to get a good take if they
have some sweetening effects in their headphone mix while tracking. These
will usually be temporary effects and will not neccesarily make it into the
final mix but they can make the difference between a good take and a bad
take. In this example, we will be using an effects device connected to
Mobile I/O’s AES ports to add some reverb to the headphone mix we make
in MIO Console.
