amplification + integration with bass (Orphean)

Hi Peter,

Meaning : If you would use the normal filter setup with the bandpass amp,
you'd still lacking the lower frequencies.

Yes, the limited amp has a smaller output transformer lacking deeper bass but in return more extended in the high frequencies than a normal output transformer (for good bass) can reach. No need to reply on this part, that is for a new topic if there is further interest in this.

When you go like suggested, the "quality" (fwiw) of the "main" amp willl
not contribute to the resulting output from the bass amp. Hence, the main
amp is no input (pre-amplifying) for the bass amp then.

Where in this topic did I suggested about quality? But your assumption is correct though, if the bass of the main amp is not okay then this is what you will hear back when using the line-level filter principle as standard used with all Oris systems.

Theoretically you'd need more power in the bass amp.

Not just more power but mainly quality power to control the bass driver without adding things to the sound.

Also I would think it needs another filter setup then. But that would be
minor adjustments (?).

It is something very different....We should start a new topic for that to explain the differences between active filtering and passive line filtering plus the (dis)advantages of using the signal coming from the main amplifier and use that for the bass...

My setup just allows for a setup as suggested. I mean, I do have/use such
a pre-amp. However, we went as "usual", leaving half of the outputs (of
the pre-amp) unused. Now, could there be benefit from changing
explicitly as per your suggestion ?

Only disadvantages in your situation. Especially if you are going to change things in the future (different amps, different pre-amp and perhaps even none with remote controlled GC).

This is related to my above "statements" of course, one of them being
about the "quality" of the main amp feeding the bass amp. I can
imagine that it just might be better to use the quality of the
explicit pre-amp. Or ?

Not always, YOUR main amp is a much better pre-amp...

Ciao,

Bert
