Up for sale is a Roll Music Systems RMS216 Folcrom, the industry-standard passive summing box for bringing analog character back into DAW mixes. Sixteen balanced input channels on standard 8-channel DB25 connectors, each independently assignable to Left, Right, both, or neither via front-panel pushbutton switches. Fully passive design; no ICs, transformers, or active circuitry, so your DAW automation and recall stay perfectly intact while the summing happens in the analog domain.

Condition: Very good some rack rash on the chassis from normal studio use, but fully functional with no impact on performance. All 32 switches operate cleanly.

Function: Passive unit, no power required. Outputs a stereo balanced 150-ohm signal on XLR, ready to feed into your preamp of choice for makeup gain (~30–40dB needed, program dependent).

What’s included: Mixer only

Let me know if you need db25 cables and we can work something out.

Notes: Great way to add width, depth, and analog glue to in-the-box mixes without the cost or footprint of a full console. Selling because [reason downsizing studio gear, don’t use it enough, etc.]. Tested and working, sold as-is.
