What are the differences between the mic inputs and the tape returns on my O1V?

Mic Inputs: The Mic Inputs (input channels 1-12) are ”full-featured” analog inputs that can accept ”microphone-level” and ”line-level” balanced or unbalanced inputs. Mic Inputs include:

– XLR and 1/4” TRS input jacks
– Input gain adjust and pad
– 48 volt phantom power
– Normal/Reverse phase select
– Input attenuator
– 4-band fully parametric EQ
– Dynamics processor
– In-line delay
– Channel fader and pan
– Auxiliary Sends 1-4
– Effect Sends 1-2

Tape Returns: The Tape Returns (input channels 17-24) are less ”full-featured” than the Mic Inputs. The Tape Returns are accessible with one of the Option I/O cards inserted in the slot on the rear panel of the 01V. If the MY8-AD or MY4-AD card is used, the Tape Returns are analog inputs. If one of the digital I/O cards is used (MY8-AE, MY8-AT or MY8-TD), the Tape Returns become digital inputs. Tape Returns include:

– Input attenuator
– 2-band fully parametric EQ
– Channel fader and pan
– Auxiliary Sends 1-2
– Effects Sends 1-2

TIP: The Tape Returns can be ”swapped” with the Mic Inputs. This allows the Tape Returns to use the full features of the Mic Inputs during mixdown or monitoring.
