It is also important that you double checking all routing, assignments, and Solo / Mute Group status.

You can check the exact audio path of any signal by referring to the input signal path diagram in

Section 2.3.

Are Solos inactive?

Clear all active Solos either individually, or by using CLEAR SOLO in the DASHBOARD screen.

Check The input!

The physical input should be correctly connected. The physical input numbers correspond to the input channel

numbers in the Ui Control Software.

Is there anything on the meters?

By checking the Input and Output path meters, you should be able to localise a problem to a large extent.

The Input channel metering comes after the Mic/Line input but before the rest of the Input Channel. Therefore, if the input signal

is valid, and you have applied enough Gain, you should see a level indication on the input meters.

Output Channel metering is tapped just before the physical output.

Are they ‘in phase’?

Phase is only likely to cause an issue if coherent signals are applied to more than one channel and they are both

routed the same way. For example, you might be using a test signal, or using two channels for the same signal.

then look for the cause of the phase issue - it may be that a balanced connection has been wired incorrectly, for example.
