Hi John,

There is no interaction and you can use either method.

I believe on Hermes "preamp off" maps to setting the Hermes attenuator
to -20 db. Should there be some text in this document explaining how the
preamp on/off setting will interact with the higher granularity ability
to set the attenuator that was just added?

Thanks,
