Nu v2 Capsules

      Nu Capsule, Nu Series, Pickups, V2

The Nu version-2 capsule is ready to go!

  1. Thicker permalloy ring for improved electromagnetic isolation, better string focus and crosstalk reduction.
  2. Bobbin-less coil to make room for the improved permalloy ring.
  3. Lower magnetic pull.
  4. Epoxy impregnated injection molded capsule.
  5. Improved preamplifier.
    1. Low noise discrete/Op Amp hybrid differential preamplifier for improved immunity to electrostatic noise.
    2. Less stringent requirements on power supply regulation and noise (although I still highly recommend using a very low noise power supply suitable for low noise audio).
    3. Expanded power supply range. You can now power the capsules from 5v up to 18v. A higher supply voltage will give you a significantly higher dynamic range. Nu v1 maxed out at 5v.
    4. Instrument-level, like before, but not as hot as Nu v1. Roland synth users say the output of Nu v1 is too hot.
    5. Better output drive. Nu v1 has a 10k output impedance. Nu v2 has a very low output impedance with a 17 mA current drive capability.
    6. Rail-to-Rail Output. Which also translates to optimal dynamic range.
The preamplifier design changes follow developments in our preamp research for the Modula line of pickups. See Modula Update: Preamp Performance Tweaks.
Technically, this is v3 now, if you count the Neo as v1. I almost forgot the Neo and the Six-pack project, where it all started.

You’ve been asking for this for a long time now. A gift to the Roland aficionado. Finally, a Roland 13 Pin Adaptor for the Nu Series Modular Active Pickups.

Nu-XR Combo

      Nu Series, XR Series

Some of you asked if it is possible to have the Nu and XR in a common baseplate. It turns out that it is indeed possible. The way to do it is have the Nu Multi, which has a somewhat lower profile, piggyback on the XR’s baseplate. This way, the Nu will still have its own height adjustment independent of the XR. You’d want the Nu capsules as close to the strings as possible (within 1mm to 2mm) to minimize crosstalk. Here’s the idea:

Announcing the Nexus

      Electronics, Hardware, Nexus, Nu Series, Release, Support Electronics, XR Series

nexus

After more than a year of continuous refinement, I’m proud to finally release the Nexus. This small, hacker friendly breakout box connects your multichannel guitar to the outside world using a specialized (LEMO compatible) multi-pin connector for up to 12 channels of audio and 7 channels of analog control voltages for by-wire (remote) control of volume, tone, patch or effects. Audio may come from standard mono-pickups or from the Nu multichannel pickup. Analog control voltages are converted to MIDI control messages.

The Nexus and related support electronics are currently only available on pre-order basis, with a 3 week lead time for the first batch. Please send us a message for inquiries and orders.

Nu Mixing

      Nu Series, Pickups, Support Electronics

solid_state_logicAn often asked question about the Nu modular pickups is about mixing to mono, or even stereo. The typical assumption is that, just like any other active pickup, you simply tie the outputs together to have a summed output. But not so fast! With 2 or 3 pickups (typical guitar setup), you might be able to get away with passive mixing. But mixing anything more than three channels is not a simple task and cannot be overlooked.
