Direct Monitoring
Direct Monitoring (DM) is a key feature of the ConnectAUDIO2/4. It enables you to monitor audio input directly from the ConnectAUDIO2/4 interface without the latency introduced when monitoring the same signal through your DAW.
DM offers Mono and Stereo modes and provides Rotary Dial control to balance the level between your
audio input(s) and the computer output.
How to Enable Direct Monitoring
1. Touch Direct on the Touch Panel. The Direct LED indicator will display green and initialize in Mono
mode by default.
2. Select the inputs (1, 2, or both) to be monitored.
3. Use the Rotary Dial to adjust the balance between audio from the input(s) and USB audio.
Working with Direct Monitoring: Mono/Stereo Modes
When you first initialize DM, it will be enabled in Mono Mode by default. If both inputs are enabled, there
will be no panning between audio sources. Toggling DM to Stereo Mode allows you to auto-pan Inputs 1
and 2 to the Left and Right sides of the stereo spectrum and enables clearer monitoring of multiple
sources.

I don't hear any sound from the speakers or headphones connected to the interface
Make sure that you have set up output levels on the unit. Verify that the output pair over which your DAW is
transmitting audio is selected on the Touch Panel.
I’ve turned on direct monitoring but I'm only hearing the computer output, not the analog input.
Verify that you have selected one or more of the analog inputs for monitoring. If neither input is selected,
you will only hear the computer output. Refer to the Direct Monitoring section for more information.

I have a device connected to the MIDI DIN connectors, but I'm not seeing it on my computer.
Verify that the MIDI DIN connections are not reversed. MIDI Out on the controller should be connected to
MIDI In on the interface, and vice-versa.
The interface is not powering up or is turning ON and OFF again.
Verify the USB cable and the USB port power. The USB port may not be providing sufficient power. The
cable may be too long or of insufficient quality to support the power supply current.
