Replacement Barcus-Berry 4000PI Pickup Sensor with Cable for use with Barcus-Berry 4000 Planar Wave system. Pickup with attached cable only, does not include the 4000PRE preamp, which is required for operation.
The Planar Wave sensor is essentially non-responsive to unwanted vibrations such as pedal and hammer noise, which are normal to the major surface planes of the instrument soundboard.
The Planar Wave sensor is, however, highly sensitive to transverse energy waves traveling in the plane defined by the soundboard and is thus able to provide full-spectrum frequency response and perfect amplitude balance across the entire instrument while achieving an excellent degree of isolation from ambient sounds, together with outstanding feedback rejection.
Note: Includes 4000PI sensor with attached cable only, does not include 4000PRE preamp, which is required for operation. Attaches to soundboard with double-sided adhesive (not included).
