Congratulations on your purchase of the Barcus-Berry Planar Wave System

The Planar Wave Piano and Harp System represents a significant breakthrough in transducer technology. The sensor employed
is essentially non-responsive to those vibrations which are normal to the major surface planes of the instrument soundboard.
It 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. The system can be quickly and
easily installed on any piano or harp and can be just as simply removed without leaving any visible evidence of its use. No tools
are required for installation.

Important

(B)

Before you begin, please check within the box to insure that it contains the following items:
(A) • One (1) Barcus-Berry Planar Wave sensor.
(B) • One (1) Barcus-Berry Piezo Buffer Preamp.

• Adhesive patches for transducer installation.

• One set of rubber feet (four each).

• Installation Instructions for Model 4000.

If any of these items are found to be damaged or missing, immediately contact

(A)

the Barcus-Berry dealer from whom the unit was purchased.

Installation

For a piano, the transducer should be attached to the soundboard as indicated in Figure 1 for grand pianos and Figure 2 for
uprights. For harps, the transducer should be attached to the face of the soundboard, for convenience, preferably near the base. To
assure proper bonding of the transducer mounting adhesive, it is strongly recommended that the area selected for attachment of the
transducer be cleaned to remove any surface dust or oily film which may have accumulated.

When you are ready to make the installation:

1. Remove the protective paper covering from each foot of
the transducer to expose the adhesive film applied at the
factory. Select the location desired for attachment, then
firmly press both feet of the sensor onto the soundboard,
normally around the middle C note.

2. Position the preamp near the keyboard at any convenient
location within reach of the transducer cable and plug the
transducer into the input jack on the rear panel.

3. Connect the Hi-Z and/or Lo-Z output of preamp to any ap

-

propriate amplifier or console input.

4. Move the power switch on the front panel of the preamp to
the “ON” position and the system will be operational.

Special notes on installation and removal…

The pressure-sensitive material used for attaching the trans­ducer feet to the soundboard is a special, high-performance
adhesive. This adhesive must be replaced each time the
transducer is removed. An initial supply of pre-cut adhesive
patches is furnished with this system.

CAUTION: Do not attempt to employ alternative methods for attaching

the transducer. The means of attachment specified above is critical for
achieving optimized performance with this system.

Additional adhesives are available. To order, please contact
the Barcus-Berry dealer from whom the unit was purchased.

When removing the transducer, simply apply sidewise pres
sure to the crossbar section above each leg until the feet of
the sensor detach from the soundboard. Any adhesive resi­due which may remain on the soundboard and/or on the feet
of the transducer after detachment can be quickly removed by
simply rubbing the surface with your thumb or fingers.

IMPORTANT: When using this system with a grand piano, we strongly

recommend that the lid of the piano be raised while the system is in use. Even
with the lid open at full stick, there will be no feedback problems or bleed from
ambient sounds, and the performance of the Planar Wave Piano System will be
enhanced by having the lid up.

This pickup can operate on phantom power provided by a mixing board or
on a 9-volt battery. To replace the 9-volt battery in the preamp, remove the
screws which secure the cover at each end of the unit and slide the cover away
from the chassis. This will permit easy access to the battery. Under average
conditions of use, battery life expectancy is at least 1,000 hours.
