Except Large and solid frame, P&G faders , 20+years old preh stillworkin pots nice VU, TT patch , most of electronics sucks. Grounding is horrible, loops all around, (I trashed most of flat cables for ground and audio). Yes, I would like to separate aux. because don't like that passive parallel ... So will be nice to see is there some interesting idea about. Master summing is classics VG. Manual says 3k3, factory mounted 4k7 summing resistors. I'm in process with new master summing (40ch TX coupled individual cabled, like neve ), and again, will be nice to upgrade Aux. in the same time. Thanks. BTW, I don't have scanner to scan manual, but I will find some way but is it possible to use some of your web hosting for posting pics? :grin:
