This is how I play out -- with the console facing upward (I figure you guys had seen 1200s and Yamaha NS-10s before, hehe.)
1620LE, with no phono cards, on the bottom. I have the internal jumper set so that Channel 6 doesn't go to the Booth Out. This enables Booth Out/Channel 6 In to act as a Send/Return to reverb.
Pioneer EFX-1000 in 1620LE effects loop. The "brackets" holding the EFX upright are cheap metal bookends with velcro.
The reverb unit is a TC Electronic M-ONE XL.
Remainder of Signal Chain: 1620LE -> Bozak Isolator -> A&H Xone VF-1 Filter.
