X-X Specification

X-X omnidirectional lapel microphone in black

Ideal for as a lapel microphone or for binaural recording, the X-X omnidirectional lapel microphone is available in a full range of terminations from its 2m lead.  Custom length leads available on request; please inquire for pricing.

The stereo versions of the X-X omnidirectional lapel microphone are supplied with matched capsules; mono versions may be ordered as matched pairs.  Stereo versions may be supplied with the leads joined together; please specify the length of the cable split at the capsule end.

The X-X offers two capsule options:

  • standard capsule with 22dBA self-noise and 132dBSPL maximum sound pressure;
  • low-noise capsule with 19dBA self-noise and 118dBSPL maximum sound pressure.

The capsules are distinguished with the metal finish on the capsule flange; gold for low-noise, chrome for standard.

X-X omnidirectional lapel microphone in white

The X-X is available in black or white.  The X-X may also be color-coded with matching rings on the XLR connector and heatshrink at the capsule to distinguish between multiple X-X microphones.  Select from white (standard for white microphones), black (standard for black microphones), red, green, yellow, or blue.  Include requests for color-coding in order comments.

X-X Specifications:

X-X microphone 3.5mm miniplug wiring configuration:
  • PC microphone (Soundblaster® compatible): tip = signal; ring = power (+3-10V); sleeve = ground.
  • Mono plug-in power (“PIP”): tip & ring = signal + power (+3-10V across 3-10kΩ); sleeve = ground.
  • Sennheiser® compatible: tip = signal + power (+3-10V across 3-10kΩ); ring & sleeve = ground.
  • Stereo PIP miniplug:  tip =  left signal + power (black or white heatshrink); ring = right signal + power (red heatshrink); sleeve = ground.
