Multi-channel input option on Orelo

[PeterSt]

Hi again Ramesh,

Yes, but ... I just woke up with knowing again how it is "constructed" ...
And it's applied for so long (like 15+ years), that I did not even realize any more that it is how it is;

The power amp, be that internal or be it yours externally, acts as a pre-amp for the bass section. This also solves the level difference between the mid-high and the bass section; once set = always set.
And for myself I could not explain that with my previous explanations.

Internal Mid-High amplifier(s) with fixed volume -> DSP -> Bass amplifier(s).
or
External amplifier with variable volume -> DSP -> Bass amplifier(s).

(bass is always levelled with mid-high, once set orderly (via the DSP volume))

Thus with Line Level input there's internally an Y split behind the one of the two amps servicing the mid-high and one branch goes to the mid-high and the other branch goes to the DSP (which is thus fed Speaker Level signal, but not the bass level which would be too much for it);

With Speaker Level input, the Y is right behind the input (but thus behind your external amplifier) and again one branch goes to mid-high and the other goes to the DSP.

With multi-channel input the same principle could be applied, now all externally. In that case, there too the balance between mid-high and bass would be preserved, once set orderly.
In this setup no internal filters are active whatsoever, so this now all has to be applied outboard, be that passive normal filters or be that DSP or a mix.
