User manual FISHMAN PRO EQ II

[. . . ] NOTE: Make sure the battery is installed with the correct polarity. You can expect 1, 400 hours of continuous use. To conserve the battery, unplug the input when you are not using the preamp. When you start to hear distortion from the preamp, it is time to change the battery. [. . . ] Treble A Boost here will help to "cut through the mix" Conversely, lowering the Treble will mellow and subdue your amplified tone. Implied Midrange Cut You can cut mids by boosting equal parts of bass and treble. 5 Outboard Acoustic Preamps Optional Belt Clip Attaches to the back of the GII or BII with two screws.

It is well suited for all acoustic instrument pickups. Enclosed in a tough injection molded case, the Pro EQ II features advanced new electronics which are quieter, cleaner and offer longer battery life than our original Pro EQ preamp. 8 User Guide PRO EQII FEATURES Power You can power your Pro EQII two ways: 1 - 9 Volt Battery Remove the battery compartment lid by sliding it up towards the top of the unit. Place a fresh 9 Volt alkaline battery in the compartment and replace the lid. NOTE: Make sure the battery is installed with the correct polarity. You can expect 220 hours of continuous use. To conserve the battery, unplug the input when you are not using the preamp. When you start to hear distortion from the preamp, it is time to change the battery. 2 - Nine-Volt AC Adapter Input Use only a Fishman 910-R or Boss PSA series regulated AC adapter. If a 9 Volt battery is in the preamp, no battery drain will occur when you use the AC adapter. Output Plug a standard instrument cable from the output to a stage amp, DI or an unbalanced microphone input on a Mixer. Input The input accepts all piezo and magnetic pickups (passive or active). When you plug in here, the 9 Volt battery switches on. To conserve battery life, remember to unplug the input jack when you are not using the preamp. It is a good idea to turn down your amp or mixer's input before you plug into the input. Doing so will protect your speakers (and your ears) from loud pops. Input Gain You'll find this control located on the back of the preamp, to the left of the sub bass control. Like a trim control on a mixer, the input gain accommodates a variety of signal levels. Use a slot head jeweler's screwdriver to raise or lower the input level. 9 Outboard Acoustic Preamps Input Gain Continued If the signal coming from your pickup is very weak, turn the input gain clockwise to reduce the overall system noise (hiss). If you hear distortion when you play (with a fresh battery), lower the input trim until it goes away. Sub Bass You'll find this control located on the back of the preamp, to the right of the input gain control. Use a slot head jeweler's screwdriver to raise or lower the sub bass level. For instruments with lots of natural deep bass, typically dreadnought and jumbo style guitars, leave the sub bass at its factory set full counterclockwise position. For instruments that don't naturally produce a lot of deep bass, such as small bodied electro-acoustic guitars, adjust this control clockwise to add bass resonance. Low Battery Light This light has two distinct functions: 1. [. . . ] It zeros in on "extra crispy" high frequency tones, the realm of harmonics and acoustic string sound. Lowering the Brilliance slider can help to reduce finger noise and fret buzz. 11 Outboard Acoustic Preamps SAMPLE EQ SETTINGS Here are a few suggested settings for the Pro EQ II: Finger Style This setting will add fullness to the bass and definition to the treble. 12 User Guide "Scooped" Mid This is the popular "smiley eq " tone that emphasizes extreme bass and treble. Strummer This is a good overall setting if you mainly strum the instrument. 13 Outboard Acoustic Preamps Sample Settings Continued Cut through the mix This setting is helpful when you need to be heard through a loud band. 14 User Guide PRO-EQ II SPECIFICATIONS Measured with all tone controls at center detent and volume at max.
