Making connections to the Mobile I/O
There are six classes of connections you can make to the Mobile I/O hard-
ware:
1. Analog Audio
2. Copper-based Digital Audio
3. Optical-based Digital Audio
4. Clock Sync
5. FireWire
6. Power
A NALOG A UDIO C ONNECTIONS
The analog I/O connections on the Mobile I/O have been engineered for
maximum flexibility in that they support both balanced and unbalanced
connections with a wide range of input and output levels and a wide range
of matching impedances. This means that Mobile I/O handles sources from
mic level to line level and from mic impedance to guitar impedance. With
that in mind, there are a number of aspects of the design that you should
take into account when interfacing with Mobile I/O.
Whenever possible, use balanced interconnects with Mobile I/O. The perfor-
mance of balanced interconnects is much higher and much more resistant to
noise interference and electrical (power) wiring problems. The expense of
balanced interconnects is not substantially higher than unbalanced connec-
tions, so if the gear that you are interfacing with supports balanced connec-
tion — use it.
If you cannot utilize balanced interconnects, there are connection schemes
that you can use that will maximize performance.
On input, at line level, it is sufficient to simply use standard unbalanced (TS)
connections. If you are interfacing with the Mobile I/O XLR inputs, you will
need to ensure that pin 3 is grounded in the unbalanced adapter cable.
More information about adjusting the input level can be found in the MIO
Console software chapter.
