It is possible on a large number of E-mu products, but not on any of the E4 rack units.
All of the Proteus modules, from the old Proteus1, through the UltraProteus and Planet Phatt, through Proteus2000 and Mo'Phatt, and on through XL-7 and Proteus 2500 (and everything in between, for a span of almost 14 years)... ALL of the Proteus modules have that send/return feature on the sub-outputs with passive summing of returns to the main stereo out (I'm still trying to work out if the sub-out returns are summed to the S/PDIF on Proteus2000 series modules).
The feature appeared on the Emax II and ESI series samplers.
The feature also appears on the E-Synth Keyboard and the E4K (which the review is talking about).
All of the E4 rack units have balanced sub-outputs, which aren't wired with summing returns (both tip and ring of the TRS connector carry the hot signal, sleeve as ground). The others had unbalanced sub-outs, which could be wired as summing returns (tip as send, ring as return, sleeve as ground).
It was a really great feature, and I miss it on my e6400Ultra. Luckily, I still have the Morpheus and PX7 on the same rack...
