• Focused on sounding better than the infamous ITB sound of the last decade?
• Striving for a more spacious organic analog sound without buying an analog console?

The RMS216 FOLCROM Passive Summing Device is definitely one way to go.

Everyone needs at least one high quality stereo tube pre and one high quality stereo FET pre-amp in the chain. Now that I have those, here is an excerpt of what more I can do with them:

Tired of the flat, narrow sound of your Digital Audio Workstation? Do individual tracks sound full and deep while whole mixes sound lifeless and thin? Can you go analog without sacrificing the recall ability of the DAW or parting with the space and money required for a large automated console? Break out of the box and let your mixes breathe again.
The RMS216 FOLCROM is a high quality passive mixer intended for analog summing of multi-channel digital mixes. The sound is up to you and your preamps.
Each of the Folcrom's sixteen input channels features a balanced analog connection on standard 8-channel DB25 connectors and a pair of pushbutton switches to assign that channel to the Left or Right output, neither, or both. It uses no active circuitry and provides no gain or level controls. By controlling all aspects of the mix from within the DAW, automation and recallability are perfectly preserved. Up to 16 different tracks or submixes can then be routed to the Folcrom for summing in the analog domain.

Looking forward to others chiming in here.
