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, the input is patched correctly, you have selected the correct Control Channel (SEL button), and you have applied enough Gain, you should see a level indication on the meters in the IN section of the Assignable Channel Strip (7.2.1).Output Channel metering is tapped just before the physical output patch.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.
