User manual FISHMAN SBT-SERIES

[. . . ] In instruments with small soundholes, dulcimers, for example, internal installation may not be practical. As a general rule, the transducer should be mounted over a freely vibrating location and not over a "dead" structural brace. The exact location for best results should be determined by experimentation. 2 Installation Guide 1. Determine the approximate location of the transducer by measuring about 1. 5" (3. 8 cm) below the bridge and a 1. 5" (3. 8 cm) below the highest pitched string and note the position where these two measurements meet. [. . . ] OR Quick & Clean The objective here is to drill out the hole with the endpin or other suitable plug in place. You may remove a loose endpin and refasten it in the endblock with cyanoacrylate glue before starting the procedure. 4 Installation Guide Note: We do not recommend this method for instruments with brittle ornamental veneers (ex: abalone) around the endblock. 1. Apply masking tape around the endblock area to protect the instrument. Locate an X-Acto saw blade 1/16" (1. 6mm) away from the body and saw off the endpin. Line up a 15/32" (11. 9mm) Spade bit in the pilot hole and begin drilling. Use steady (but not heavy) pressure, especially as the drill exits inside the guitar. To avoid damage to the instrument, let the drill come to a complete stop before removing it from the hole. Install the Pickup 1. Gently bend back the strain relief/sleeve tab to gain better access to the Tip terminal. Solder the pickup "hot" wire to the Tip terminal, which is the shortest of the three tabs. Refasten the shielding cap to the jack. OPTION: PERMANENT TRANSDUCER MOUNTING Although excellent results are obtained by using the adhesive pads, an increase in overall frequency response and output will result when the transducer is bonded to the soundboard with a "hard" adhesive. We suggest a gap-filling cyanoacrylate such as Loctite "Black MaxTM". Be aware, however, that such a procedure is permanent and irreversible; removal may result in damage to both the transducer and the inner surface of the soundboard. 5 SBT Series - SoundBoard Transducer TM Wiring Options with the Fishman Switchjack The Switchjack T-R-S-S (Tip/Ring/Sleeve/Switch) stereo switching endpin jack allows simultaneous stereo operation and battery switching for active pickups. This new configuration simplifies stereo wiring with many pickup combinations that were once incompatible. Switch (Long Terminal) Ring (Medium Terminal) Guitar Tip Sleeve 1/4" Stereo Plug Tip Shield (Short Terminal) Ring To gain better access to the Tip, Ring and Switch terminals, gently bend back the Strain Relief/Sleeve tab, before you begin to solder. Pages 7 & 8 illustrate the various wiring options made possible by the Switchjack. 6 Installation Guide Mono Wiring an SBT Series Pickup Pickup Signal to Tip Shield to Sleeve Stereo Wiring a Second Pickup to an SBT Series Pickup 2nd Pickup to Ring Common Ground Pickup Signal to Tip 7 SBT Series - SoundBoard Transducer Adding a Microphone to an SBT Series Pickup * Microphone to Ring Common Ground Pickup Signal to Tip Zener Diode between Ring & Sleeve Stereo Wiring with an Active Pickup Negative Battery Wire to Switch 2nd Pickup to Ring Common Ground Pickup Signal to Tip * For use with the Fishman Blender System 8 Installation Guide Fasten the Jack in the Endpin Hole Follow this sequence when installing the endpin jack: 1 - Shielding Cap 2 - First Large Hex Nut 3 - Large Dress Washer 4 - Star Washer 5 - Guitar Endblock 6 - Small Dress Washer 7 - Small Dress Nut 8 - Strap Button 2 34 5 6 7 8 1 The jack should protrude at least 5/16" and no more than 11/32" outside of the guitar body for proper fit. After fitting the small dress washer and nut over the end of the jack, insert the 3/32" allen wrench through the small hole on the end of the jack. Tighten the nut with the 1/2" open end wrench while holding the jack in place with the allen wrench. Thread and hand tighten the strap button. NOTE: With the strap button in place, the end of the jack should protrude slightly, so that when a plug is inserted, it will snap securely in place. INSTALLING PARTS · SBT-HP with 42" Cord and 1/4" Jack · (3) Double-sided Adhesive Pads · Adhesive-backed Jack Holder THE MODEL SBT-HP The Model SBT-HP is designed for harp or piano. As a general rule, the transducer should be mounted over a freely vibrating location and not over a "dead" structural brace. The exact location for best results should be determined by experimentation. 9 SBT-HP Installation Continued 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. Apply an adhesive pad to the shiny brass face of the transducer and mount outside the instrument, 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. Plug the pickup into an amplifier and experiment with the vertical location of the transducer. [. . . ] The SBT can also be plugged into inputs as low as 1 M with adequate results; the bass frequencies will be slightly rolled off. Preamps We strongly recommend using a 10 M , impedance matching, buffered preamp in conjunction with the pickup. Permit long cable runs (after the preamp) without signal deterioration.
