Product Description

The X-R interchangeable capsule microphone consists of two components:  the capsule amplifier and eight available capsules:

Polar Patterns
  • cardioid:  vent holes without blind hole
  • nearfield cardioid:  vent holes with one blind hole mark
  • side-address cardioid: 14mm capsule with female RCA jack output
  • cardioid, low sensitivity:  vent holes with two blind hole marks oriented diagonally, representing high-frequency rolloff
  • hypercardioid:  vent holes with two blind hole marks oriented vertically, representing front and rear polar response lobes
  • omnidirectional:  no vent holes
  • omnidirectional, low sensitivity:  no vent holes with two blind hole marks oriented diagonally, representing high-frequency rolloff
  • measurement (omnidirectional):  6mm capsule, steel grille, no vent holes, male RCA only

The cardioid capsule is intended for general use on all sources where off-axis rejection is important, but a low-frequency rolloff outside the nearfield is not desired.

The side-address cardioid is also a general use capsule, with better low-frequency extension and improved noise compared with the standard cardioid capsule.  The side-address cardioid is only supplied with a female RCA jack.

The nearfield cardioid capsule has reduced farfield low frequency response.  When placed within 30cm (1′) of the source, the capsule’s proximity effect will provide a natural tone on the source with excellent rejection of farfield low frequency signals.  It is recommended for instrument mount in more difficult acoustic environments where low frequency bleed from other instruments must be rejected.  It is also excellent in combination with the omnidirectional capsule using the acoustic low-pass filter; the combined pattern yields the natural low-frequency response of the omnidirectional capsule combined with the precise stereo image of a directional capsule.

The low-sensitivity cardioid and omnidirectional capsules have reduced sensitivity and increased SPL handling for close-mic techniques on very loud sources, such as drums or instrument amplifiers.  Both capsules have attenuated high-frequency response to yield a frequency response similar to dynamic microphones.

The hypercardioid capsule has superior rejection of off-axis signals.  It is especially intended for instrument mount or stereo recording in difficult acoustic environments.

The omnidirectional capsule provides the most natural response when mounted on an instrument.  It may also be used with the table mount as a boundary microphone.  The optional equalization disc provides an on-axis high-frequency boost for enhanced directivity.

The measurement capsule uses a flat-response 6mm omnidirectional capsule, and includes a 1/3 octave calibration report.  The measurement capsule is only supplied with a male RCA plug.

All capsules may be attached remotely to the amplifier body with an RCA extension cable.

Capsules include windscreen.

The X-R microphone capsule amplifier

The X-R microphone capsule amplifier is a microphone “body” that mounts in a standard mic clip (included), and requires +9V to +52V phantom power.  The capsule output is on pin 3 (negative polarity), with an impedance-balanced output on pin 2.  Thus, capsule amplifier will yield positive polarity when connected to a balanced input amplifier via a standard XLR microphone cable.  When used into an unbalanced input (as with some portable phantom power supplies), pin 3 should be connected as the signal lead.

The X-R microphone capsule amplifier may be supplied with a female, male, or right-angle male RCA input.  Right-angle and male-male adaptors are also available.

Two X-R capsules may be connected with the RCA Y adaptor, which will mix the two signals from the capsules.  When used with an RCA extension cable, the Y adaptor mixes two discrete sources into a single microphone channel.  Also, the Y adaptor may be used to blend an omnidirectional capsule with a directional capsule.  This technique is especially useful with the acoustic low-pass filter, yielding a hybrid pattern with a directional high-frequency response and an omnidirectional low-frequency response.

The capsule amplifier includes a standard 5/8″-27 mount microphone clip.
