Hi Everyone,
i just wanted to check out how the KPA would handle two parellel amps. Test setup was as follows:
KPA -> Splitter -> Amp1 (JVM 410H)-> Cab1 (Marshall 1960 with V30) -> AKG C3000 and SM57 - > Mixer -> KPA
Splitter -> Digital Delay 15 msec. -> Amp2 (ENGL 860)-> Cab2 (Marshall 1960 with T75) -> Sennheiser 835 - > Mixer- KPA
The Delay was necessary to ged rid of the nasty phasing problems and it seems to make the sound a little "broader". I am not totally satisfied yet, but it sounds interesting. Maybe i will investigate further 
Check ou out if you like. Have fun!!!
