switch function details

USB 1-2

In this setting, no inputs are monitored. Only the output signal sent from the computer to MAIN output 1/2 is routed to the

headphones.

USB 3-4

In this setting, no inputs are monitored.

Only the output signal sent from the computer to USB output 3/4 is routed to the

headphones. This setting is useful when a separate output mix has been setup in the software.

For example, to use the Cue Out feature in Ableton Live (not included), perform the following:

1. Set the

Cue Output

on the Master channel in Ableton to 3/4.

2. Under the

Options

menu in Ableton, select

Cue Switches

.

You’ll see the Solo buttons on each track change to

Headphone Cue buttons.

3.

Then, set the iO4 PHONES select switch to

3/4

. This will allow you to listen to Ableton’s

independent Cue Out mix in your headphones while a different signal is sent to your Main Output

1/2.

With the PHONES select switch set to

3/4

, any tracks in Ableton which have the Headphone Cue

button enabled will be routed to the iO4 headphone mix

ALL Outputs

This is the setting that will provide the most familiar operation to most users. In this setting, all iO4 inputs are monitored.

Using the

MIX

knob, the inputs can be blended with a sum of all output sent from the computer to the 1/2 and 3/4 Outputs

on the iO4. For most applications, this PHONES select switch setting or the

1/2

setting will be used.
