DESCRIPTION
Designed in response to requests from players, this versatile preamp/EQ/DI is at home everywhere from local open mic nights to major festival stages. With its simple yet precise controls, you can quickly dial in the natural acoustic sound you're looking for; loud, clear and feedback free.
The Pro-EQ Platinum's four-band equalizer is modeled after our gig-proven Prefix™ Plus onboard preamp, with sliders that are assigned to just the right frequencies for acoustic equalization. A semi-parametric midrange control employs a "constant Q" filter for more precise and consistent tone adjustments. Also borrowed from the Prefix™ design are feedback fighting phase and notch controls.
The Pro-EQ Platinum features our exclusive "Voltage Doubler" technology, which improves both the dynamics and clarity of any pickup. Another innovation utilized in the Platinum is our Smooth™ acoustic compression circuit. This control removes the harsh percussive edge from your amplified sound when you play hard.
Sound engineers will appreciate the Pro-EQ Platinum's pro-audio features which include a balanced XLR out, an XLR pre/post EQ switch, plus optional 48-Volt phantom power operation. This means no more batteries or wall warts if your mixer has phantom power. Unique to the Pro-EQ™ Platinum is a hum-

killing ground lift switch that (unlike other acoustic preamp/DI's) works even when phantom power is applied to the preamp.
QUICK START
1.If you are using the XLR output, set the Pre / Post switch to "Post" position.
2.Adjust the Input gain so that the Clip/Low Battery light barely flashes with strong strumming.
3.Strum hard and raise the Smooth knob up until you hear the Compressor take the percussive edge off your highs.
4.Phase: Flip the Phase switch to the position that sounds best and suppresses mid-bass feedback
5.Notch: To squelch deep bass feedback, adjust the Notch dial between 1:00 and 2:30. The Notch is off in the 7:00 position.

POWER
You can power the preamp three ways:
1. Nine-Volt Battery
Squeeze the two tabs on the top of the preamp together and the battery drawer will pop out. Pull out the Battery clip and snap in a fresh 9-Volt alkaline battery. You can expect 120 hours of continuous use. To conserve the battery, unplug the input of the Pro EQ Platinum when you are not using the preamp.
2. 48-Volt Phantom Power Option
Many microphone mixers can phantom power the Pro EQ Platinum through a standard XLR cable. Turn on phantom power at your mixer and connect an XLR-style microphone cable between the Pro EQ Platinum's XLR out and the mixer's input. The green "phantom" LED lights up when phantom power is supplied to the preamp. Note that the ground lift for the Platinum works even with phantom power applied to the XLR out.
No battery drain will occur when you use phantom power.
3. 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 an AC adapter.
INPUT
This is for all piezo and magnetic pickups (passive or active). When you plug in here, the 9-Volt battery switches on. Remember to unplug the Input Jack when you are not using the preamp, to conserve the battery's life. It is a good idea to turn down your amp or mixer's input before you plug into this input. Doing so will protect your speakers (and your ears) from loud pops.

INPUT GAIN
Use this knob to set the input level of the preamp for the strongest signal with no noise or distortion.
Adjust the input gain control so the Clip/Battery Low light faintly flashes when you strum hard. Like the trim control on a pro-audio mixer, the input gain accommodates a variety of signal levels.
Input gain is also critical for calibrating the Smooth acoustic compression circuit (see "Smooth" below).
CLIP/LOW BATTERY LED (LIGHT EMITTING DIODE)
This light has three distinct functions:
1. Power Up Indicator
The Clip/Battery Low LED will flash briefly when you first turn on the preamp. Some people ask us, "Why doesn't this light stay on, like a conventional pilot light?" Well, a steadily lit LED devours too many precious hours of battery life. By briefly flashing the light when the unit turns on, we conserve power and extend the useful life of the battery.
2. Clip Indicator / Smooth Acoustic Compression Calibration
The Clip/Low Battery LED will light brightly when the signal from your pickup overloads and distorts the input of the Pro EQ Platinum preamp.
Adjust the Input gain control until the Clip/Low Battery LED faintly flashes when you play your hardest. This will give you the cleanest signal into the preamp, with no distortion. Setting the input gain in this way is also essential for calibrating the Smooth (acoustic compression circuit).
3. Low Battery Warning
When the Clip/Low Battery LED lights steadily with no signal present, it is time to change the battery.
