A portable mixer based on EMI REDD.37 ans Smart Kit 1024, 1126

Discusused briefly with Alexandros who co-suggested series variable resistors after the mic ie before any active stage like EMI Germany conceived REED consoles in order to have an almost infinite dynamic range. Passive EQ after the mic or before any active amplifier device. How would it look inside a pretty Retex ABOX small console box? Adding done too before any active device, BBC way!
