The reverb tank pickup amp goes to the pair of reverb level sliders and then *is* phase split at the reverb preamp inputs. On an ARP this is on Bd4-2.BLogic12 wrote: ↑Sat Feb 18, 2023 11:50 am Interesting thing I’ve been running into- when the have the left and right channels going to my audio mixer, if I have the two channels panned center, the spring reverb cancels out. If I pan the channels hard left and hard right the reverb returns/becomes audible.
The non reverberated/dry signal dosnt seem to be effected when panned or not panned just the reverb sound.
Not a huge deal I don’t think because if I’m running it mono I only need one channel, but kind of weird, like the reverb is out of phase between the two channels (but the dry signal isn’t?).
These two potentially phase cancelling outputs are fed into the left and right 'main' preamps which are both inverting.
The mixer output is also inverted relative to its input and this result goes to the pan section of the circuit where one side or the other sees more grounding to effect the pan function. From this T the two now pan processed outputs -top of T- join the reverb preamp outputs at the 'main' preamps and mix into virtual GNDs there.
Your conclusion is correct. The reverb is split-phased and the main mixer is not.
