Endorphin.es Cockpit 2
Four-channel stereo performance mixer with sidechain ducking
6 HP Eurorack module
The Cockpit2 is a 4-channel stereo performance mixer for Eurorack that accepts both modular and line-level signals, blending them through analog VCAs with digital encoder control. It features an onboard sidechain ducking compressor with three modes, a high-current headphone/monitor output, and infinite daisy-chaining for larger setups. Its musical character is that of a live performance hub — clean, flexible, and expressive.
Features
- 6 HP width, up to 1.5 inches depth — super slim and SHUTTLE system friendly
- 4 stereo channel performance mixer with analog VCAs and digital encoder control
- Each channel accepts stereo or mono, modular or line-level signals
- Bi-color LED per channel shows level brightness (green = active, red = muted) and ducking status
- Channel mute via short press of encoder button; long press enables/disables ducking on that channel
- Encoder positions and settings saved to memory every few seconds and recalled on power-up
- On-board sidechain ducking compressor with three modes: CV, audio, and trigger
- Sidechain input self-patches to sum of all channels when no cable inserted (mode 1 and 2)
- Master stereo output via 3.5mm TRS with high-current headphone drive capability
- Blue master output level knob from full silence (CCW) to high gain (CW)
- Infinite daisy chain capability via dedicated Master/Slave pins using female/female jumper wires
- Compatible daisy chain with original COCKPIT and COCKPIT2 versions
