Besides the 16 mic inputs on the Audient Zen console the room has a rack of external preamps. The rack contains two Chameleon Labs 7602 XMODed preamps. The TFPro P2 is no longer in production and works wonders on guitar cabinets. Malcolm Toft designed the ATC2 and is is a great piece of kit. The EQ section is fabulous, the preamp is functional but could use a little more gain and is also no longer in production. Below that are two Neve 1084 clones.
This list does not include the DIY and tube preamps. Check the DIY section for those.
