Warranty repairs or replacements will be sent automatically free of charge. [. . . ] Without a Fishman PowerchipTM: A mono instrument cable will short out the PowerbridgeTM Pickup, but your magnetics will function exactly as they did before you installed the PowerbridgeTM. · Instrument (not Cable included) Depending on how you want to set up your PowerbridgeTM system, you can use one of the following three instrument cables (available from your Fishman dealer). 1 - Stereo "Y" Cable This will split the PowerbridgeTM and magnetic pickup signals and send them to separate amplifiers or other destinations (PA, recording devices, etc. ). PowerchipTM Stereo Output Jack (Tip/Ring/Sleeve) PowerbridgeTM Mono Instrument Cable Magnetic Stereo "Y" Cable 2 - Stereo Instrument Cable PowerbridgeTM Both magnetic and piezo Magnetic Signal Signal signals can be sent through a (Ring) (Tip) single stereo instrument cable to one of our outboard PowertronicsTM preamps. From there, magnetic and piezo signals can be either combined to a single mono output or split to separate stereo outputs. Pure · Basic Passive Setup Stereo Output Jack (Tip/Ring/Sleeve) NOTE: For best results, use a "2 Pair" premium stereo cable (available through your Fishman dealer) with separate shielding for both the PowerbridgeTM and magnetic signals. Optional Passive Volume Pot PowerbridgeTM Stereo Outputs The simplest way to get the PowerbridgeTM Pickup up and running is to simply wire it and the magnetic pickups to Tip/Ring outputs of the supplied stereo jack. A stereo "Y" cable or a standard stereo cable can then carry the two signals. From there, all mixing and blending functions will be performed offboard the instrument. A Fishman PowerblendTM Pedal is especially suited for offboard blending/mixing with this passive setup. Stereo Instrument Cable to Stereo Input For a passive setup, you don't want to tie the PowerbridgeTM and magnetic pickup wires together at the guitar's mono output jack. This may seem like a good idea, but it won't work. If you connect the piezo and magnetic outputs, you will experience a loss of tone and a very bizarre and un-musical interaction between the PowerbridgeTM and magnetic pickups. Magnetic and piezo pickups operate on different electrical platforms. Magnetics are "inductors" and piezos are "capacitive" devices. The solution is to electronically isolate or "buffer" the two signals with an active mixing circuit like the Fishman PowerchipTM. Magnetic F ISHMAN P OWERBRIDGE TM P ICKUP I NSTALLATION G UIDE Wiring Instructions · Preliminary Notes To prevent 60 Hz hum, the entire PowerbridgeTM Pickup signal path should be fully shielded. The control cavity, jack cavity, and any non-conductive surface to which the controls are mounted (such as a plastic pickguard) must be shielded with adhesive-backed foil or conductive paint. The shielded cavities should then be grounded. For complete hum prevention, the included stereo jack must also be shielded. To do this, we've included a piece of shielding foil. After you have soldered the wires to the jack, roll the foil into a tube so that the insulation is on the INSIDE and surround the stereo jack with the tube. Connect the foil side of the tube to ground by soldering it to the shielding of the PowerbridgeTM Pickup wire or to a jumper that is connected to any ground. If your instrument has active magnetic pickups (requiring an onboard battery), you will need a special 9 Pin Switching Jack (Fishman Part Number ACC-PBR-9PJ), available through your Fishman dealer. Passive Setup Bridge Installation · Strat® Style Guitars The VMV PowerbridgeTM is a direct replacement for Fender ® Stratocasters® with a 2. 22" (E to E, center to center) pivot screw spacing. [. . . ] Connect the magnetic signal wire to the Tip terminal. Connect the included 5 M resistor between the ring and sleeve terminals. Stereo Jack ON OFF ON · Routing the PowerbridgeTM Pickup Wire · With a 3/32" (2. 4 mm) aircraft bit, drill a hole from the vibrato cavity to the control cavity. · Route the PowerbridgeTM Pickup wire through this hole.
