KOMA Elektronik Doppeldisk | Bidirectional Electromagnetic Drone Disk Pickup & Emitter

Q: Does the Doppeldisk include a 3.5mm patch cable in the box?
A: No—unlike the standard handheld pickups that have a fixed 1-metre lead, Doppeldisk features an integrated 3.5mm mono jack socket so you can use any standard 3.5mm TS Eurorack patch cable at the exact length your setup requires (and easily swap cables if one ever wears out).

Q: How does the Doppeldisk work "in reverse" as an electromagnetic sound emitter?
A: Instead of listening to fields, you can patch any standard headphone output, line output, or Eurorack oscillator/audio signal straight into the Doppeldisk—no external power amplifier required. The coil radiates your audio as a localized electromagnetic field that you can sweep and play in mid-air using your Haloplane or Chromaplane pickups.

Q: Can I use the Doppeldisk without a Haloplane or Chromaplane for field recording?
A: Yes! Connected directly to an audio interface or portable field recorder preamp, Doppeldisk acts as an ultra-sensitive electromagnetic induction microphone for capturing the hidden hums, rhythms, and textures of laptops, power supplies, motors, and synth circuitry.

Q: Does the Doppeldisk require batteries or 48V phantom power?
A: No. Doppeldisk is a completely passive bidirectional electromagnetic coil transducer—do not apply 48V phantom power when connecting it to microphone preamps.

Q: How many fields does the Doppeldisk cover compared to the standard pickups?
A: Thanks to its flat 7 cm circular footprint and very high coil sensitivity, a single Doppeldisk can span up to 3 adjacent fields at once on a Haloplane or Chromaplane, locking in rich, stationary hands-free chordal drones without sliding off the surface.
