User manual FISHMAN C-100

[. . . ] The C-100 is a bridge mounted, piezo-ceramic pickup. It senses string vibrations via a single piezo element, fastened to the instrument's wing slot with a patented floating mount. The pickup is terminated with a Switchcraft 1/4" jack that mounts to the tailpiece. The C-100 installs in minutes, with only minor alterations required. [. . . ] Warranty repairs or replacements will be sent automatically free of charge. If FISHMAN TRANSDUCERS determines the item is not covered by warranty, we will notify you of the repair or replacement cost and wait for your authorization to proceed.

Remove all rosin deposits from the bridge of the instrument. Examine the bridge closely to make sure that the wing slots are free of warps or irregularities and that the slots present flat parallel faces. ® 2 C-100 Cello Pickup C-100 Cello Pickup 4. Once the transducer is properly inserted into the bridge, the next step is to mount the adhesive-backed jack mount to the back side of the tailpiece. First, peel off the release film from the holder and then press the holder firmly in place below the fine tuning machines of the tailpiece. Position the holder so that the jack, when slipped into the holder, will be at a right angle (90 degrees) to the tailpiece. Insert the jack into the holder and snap shut. Since the wire is somewhat microphonic, it should not be allowed to lie on the face of the instrument. C-100 Cello Pickup The C-100 will sound best when plugged directly into an input with a 10 Meg Ohm impedance. At 10 Meg Ohm , the full frequency response of the instrument is reproduced. The C-100 can also be plugged into inputs as low as 1 Meg Ohm with adequate results. At 1 Meg Ohm , the bass frequencies will be slightly rolled off. INSTALLATION 1. Measure the opening of the bass side wing slot on the bridge with a vernier caliper. The opening should be between . 060-. 090" (1. 5-2. 3mm) for proper fit. If the wing slot opening of the cello measures more than . 090" (2. 3mm), the leg facing the pickup must be shimmed. For that purpose, we have provided a strip of wooden shim material that can be easily cut with scissors, stacked and glued to produce a shim of any required thickness. Slide the transducer into the bass wing slot as shown. Make certain that the sensing element is in contact with the wing face and that the spring (made of tempered beryllium copper) is in contact with the corresponding "leg" face of the bridge. NOTE: For best performance, the ultimate wing slot opening should be . 070" (1. 8mm). Preamps We strongly recommend using a 10 MOhm, impedance matching, buffered preamp in conjunction with the pickup. Realize the full frequency response potential of the pickup. [. . . ] Accordingly, the performance may be adversely affected if the wing face has been stylized or carved in any way. DIRECT BOXES You can plug the C-100 into an "active" direct box (1-10 Meg Ohm input) with very good results. Using a passive direct box will sound weak and thin. INSTRUMENT CABLE Cable lengths over 10 feet (before preamp) will cause audible high frequency loss. Use a high quality, low capacitance shielded cable. This will insure minimal tone coloration and hum. [. . . ]
