What's the difference between the Analog outs and Monitor outs, and how do I send to the
headphones?
• The Analog outputs get their signal from “Analog 1/2” in MIO Console, and their level is controlled
via software
• The Monitor outputs and headphones get their signal from “Monitor L/R” in MIO Console, and
their output levels are controlled via the front panel knobs
There are six classes of connections you can make to the ULN-2 hardware:
1. Analog Audio
2. Copper-based Digital Audio
3. Optical-based Digital Audio
4. Clock Sync
5. FireWire
6. Power
Analog Audio Connections
The analog I/O connections on the ULN-2 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 ULN-2 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 ULN-2.
There are really three distinct analog input stages available in a ULN-2 input:
1. The Mic amp, which is fed by the XLR portion of the Combo connector.
