InnerTube Audio Atomic Sumthang Summing Unit

This one was used lightly in my smoke free studio.

Manufacturer's Description from InnerTube

Old-school analog crustaceans that we are, we at InnerTube recognize the productivity that digital audio workstations (like Digidesign Pro Tools and others) has made possible. Running the outputs through a high-quality mixing console has become a favorite best-of-both worlds solution for those who want digital flexibility and analog sound quality. But what if you don't have a large-format console, or prefer to mix "inside the box"? Well, we thought up the Sumthang just for you.

It sums eight line-level (+4) inputs into two outputs, using a top-secret vacuum tube circuit for sound quality that we think mops the floor with any other "analog" summing box on the market today. Ins and outs are transformer-balanced. Units can be cascaded together to bring as many analog outs as your DAW has into the stereo outs of your main Sumthang unit, and we've been kicking around plans for a 16-channel dedicated expander. An oversized output volume knob and super-accurate VU meters let you tweak the signal to the liking of your two-track recording or monitoring system, and even better, they look important.
