Signal passes through AVR

Hello all,

I have an Arcam AVR600 which I use for movies/music but also as a distribution center to feed several integrated amps. The signals entering and exiting the Arcam are all analog and exit via the fixed-level outputs. Toggling volume or processing options on the Arcam has no effect on the output signal.

So my question is, is the signal being altered by passing through the Arcam vs if I ran the signal directly to the integrateds?

I like to option of using the Arcam as a central hub/distribution center as I frequently change out integrated amps downstream from it and I would like to have all sources available to each integrated.
