About the Switchcraft MMVP
The Switchcraft MMVP is a professional-grade TTTiny Telephone — the slim bantam plug pro patch bays use to fit 48+ points into a single rack space.

A 3U box takes three slices; half-rack gear pairs two units side by side in one.. The normalledA patch bay default path: the top jack feeds the bottom with nothing plugged in. Inserting a cable breaks (full) or taps (half) that path. configuration means signals pass straight through until you patch over them, which is perfect for establishing default signal routing in your rack while maintaining the flexibility to re-route on the fly. A staple in studio and broadcast installations that also works well in complex playback rigs.

Its job is simple in concept and indispensable in practice: it gives you a central place to establish and override signal routing without touching the gear itself.

The normalledA patch bay default path: the top jack feeds the bottom with nothing plugged in. Inserting a cable breaks (full) or taps (half) that path. configuration is the key operational detail here. In normal operation, top-row signals pass straight through to the corresponding bottom-row destinations — your default routing is always active without a cable plugged in. Insert a TTTiny Telephone — the slim bantam plug pro patch bays use to fit 48+ points into a single rack space. patch cord into either jack and you break the normal, redirecting signal on the fly. At 90mm deep and 1.3kg, this bay is genuinely shallow and light, which matters when you're stacking it into a road case with tight rear-cable clearance. It draws zero power, so it adds nothing to your PDU load and needs no rack space planning beyond the single U.
The MMVP is the right call if you're running a rig complex enough to need analog routing flexibility — think multi-source playback rigs, hybrid console setups, or any situation where your default signal path might need to change between acts without a re-patch at the gear. It is not the right call if your entire rig runs on a single digital snakeA multicore cable bundling many channels into one stage-to-console run. A sub-snake collects one corner of the stage into a drop box. or if all your routing lives inside a console or DAWDigital Audio Workstation — the recording and playback software (Logic, Ableton Live, Pro Tools) at the center of a computer rig..

In the rack
- Label both rows of the bay before the rig goes on the road — use consistent color-coded TTTiny Telephone — the slim bantam plug pro patch bays use to fit 48+ points into a single rack space. cords (e.g., red for sends, black for returns) so anyone touching the bay mid-show can read it without a legend.
- At 90mm depth, rear cable dressing is tight but manageable — use right-angle TTTiny Telephone — the slim bantam plug pro patch bays use to fit 48+ points into a single rack space. connectors on your loomSeveral cables bundled and run as one — keeps rack interconnects tidy and makes load-in one grab instead of eight. if you're working inside a shallow pull-out drawer or a lid-load case with limited rear clearance.
- Map the normal path on paper first: top row is typically your sources, bottom row your destinations. Committing to a consistent convention across the whole rig means a substitute tech can troubleshoot the bay without calling you.
- Place it near the middle of the rack vertically if possible — TTTiny Telephone — the slim bantam plug pro patch bays use to fit 48+ points into a single rack space. patch cords are short by nature, and positioning the bay closer to the gear it serves reduces the chance of a cord pulling a jack loose during a fast changeover.
