In summing there are two approaches :- the voltage summing traditionally used by vintage Neve consoles and virtual earth used by later Neve and most other manufacturers.
Neither of these are passive as the consoles use input amplifiers and bus and output amplifiers.
A passive mixer is a box full off resistors

Looks like I was wrong about the chandler after looking at the site again. It's the Shadow hills equinox I was thinking about mostly but I swear I remembered thinking the chandler was passive and the dangerous 2 bus was too. After looking at their site I think I may have been wrong. A passive mixer just doesnt seem like as much fun.
