FOR HARP MOUNTING
1. The approximate pickup position will be between 1/3 and 1/2 the soundboard's length, starting
at the bottom of the soundboard, 1" out from either side of the center brace. The resulting
intersection of the two measurements provides a good test location for the transducer.
2. Apply an adhesive pad to the shiny brass face of the transducer and mount outside the instru-
ment, at the location indicated in Step 1. The transducer wire should follow the grain of the
soundboard and point toward the bottom of the instrument.
3. Plug the pickup into an amplifier and experiment with the vertical location of the transducer. If
you detect boominess or feedback, relocate the transducer higher up on the soundboard. In
no case should it be necessary to mount it higher than 1/2 the distance. Use increments of
about 3 inches.
CAUTION: Removal for relocation should be performed by gently sliding a thin plastic credit
card between the transducer and the soundboard.
4. Once you have found the "sweet spot" for the pickup, mount it at the same spot inside the
instrument.
5. Plug the instrument into an amplifier. If boominess or feedback occurs, relocate the transduc-
er as detailed above.
6. Remove the protective film from the bottom of the jack holder and mount the holder in a con-
venient location. We recommend a location on the base of the instrument, if possible. We do
not recommend mounting to the soundboard.
FOR PIANO MOUNTING
A single SBT-HP mounted on an acoustic piano soundboard is an effective means of providing
high volume amplified sound reinforcement when used in conjunction with one microphone. The
microphone should sense the bass register of the piano while the transducer’s signal, when mixed
with the microphone signal, will provide punch and clarity to the middle and upper ranges of the
piano.
The SBT-HP should be mounted to the piano soundboard at a location adjacent to the higher
strings. For example, on a grand piano the transducer should be placed directly on the sound-
board within the third-largest ranges of the piano.
For additional instructions, see the instructions above for mounting the transducer to a harp.
