[. . . ] This warranty does not cover any consequential damages or damage to the unit due to misuse, accident, or neglect. Fishman retains the right to make such determination on the basis of factory inspection. Products returned to Fishman for repair or replacement must be shipped in accordance with the Return Policy, as follows. [. . . ] Plug a standard mono cable into a PowerchipTM equipped guitar and you can mix piezo and magnetic signals right on the instrument. (See the PowerbridgeTM System User's Guide for PowerchipTM description. ) · Instrument Cable (not 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). PowerchipTM Stereo Output Jack (Tip/Ring/Sleeve) PowerbridgeTM 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. ). Mono Instrument Cable Stereo "Y" Cable Magnetic PowerbridgeTM Signal (Ring) Pure Magnetic Signal (Tip) 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. 2 - Stereo Instrument Cable Both magnetic and piezo signals can be sent through a single stereo instrument cable to our PowerblendTM pedal. From there, magnetic and piezo signals can be either combined to a single mono output or split to separate stereo outputs. Stereo Output Jack (Tip/Ring/Sleeve) Optional Passive Volume Pot PowerbridgeTM Mono Instrument Cable Magnetic · Basic Passive Setup Stereo Outputs The simplest way to get the PowerbridgeTM Pickup up and running is to 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. For a passive setup, don't tie the PowerbridgeTM and magnetic pickup wires together to a 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 Stereo Instrument Cable to Stereo Input Magnetic and piezo pickups operate on different electrical platforms. Magnetics are "inductors" and piezos are "capacitive" devices. To mix signals on the instrument you'll need to electronically isolate or "buffer" the two signals with an active mixing circuit like the Fishman PowerchipTM. 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. [. . . ] You can also instantly split signals by simply changing to a stereo cable or stereo "Y" cable. See the PowerbridgeTM System Users Guide for PowertronicsTM descriptions. Sleeve 5Meg Resistor Both Mag Piezo Passive Volume for the PowerbridgeTM This circuit that is easily assembled from "stock" guitar pots and components available at any electronics parts retailer. You will need: · 250 k audio taper pot · 330 k resistor · 820 pF capacitor · 1500 pF capacitor This network will attenuate the PowerbridgeTM so that it better matches levels between magnetic and piezo pickups.
