Hi,
I am going to assemble a chain of modules on slots (smth like motherboard with modules) to condition subwoofer signal.
Does the order of modules matter? F.ex., due to construction matters I consider:
1. Buffer/summer of L+R chanel + Linkwitz transform
(both circuits sharing dual opamp, linkwitz transform needs a buffer)
2. Lowpass filter.
3. Phase shifter (elaborate schematics, requires dual opamp, has buffer)
4. Subsonic.
Eventually can switch 3 and 4. I want the phase shifter 3-rd or 4-th, so that the phase pot shares a dual digital pot whit the volime pot
(before the power amp stage). It will be easier pcb-wise if the digipot is closer to positions 3/4.
These are mostly construction/design considerations.
I assume, that the order we apply the signal conditioning does not really matter.
I only care if the input/output of each module has reasonable impedance.
And - the volume pot to be at the end of the chain for better signal to noise ratio (line level input for the whole chain)
Is that all ok
?
Kind Regards
