Fishman PRO-PLT-301 Platinum Stage EQ/DI Analogue Preamp
The preamp itself utilizes a high-headroom Class-A design, with a four-band EQ section that can be voiced separately, by means of a switch, for bass and guitar. A phase switch aids you in the never-ending battle against feedback in live scenarios. To add a little more volume for solos or other stand-out sections, a boost button has been provided, its level of gain adjustable by means of a wheel located next to the button. Simply depress this button to engage the boost. You'll also find an input trim pot to better attenuate your pickups to the signal path provided by the Platinum Stage. It comes with a belt clip for easy on-stage attachment to your person. In addition to drawing upon 48V phantom power, the unit can run using a 9V battery, or with an optional power supply.

The unit's EQ Mode switch offers two separate voices. Set to Guitar, the tone controls are voiced to be most useful for recording or amplifying acoustic guitar and other instruments. Set to bass, the tone controls are tailored for recording or amplifying acoustic and electric bass.
Low Cut: A variable high-pass filter, labeled low cut, can be used to remove sub-sonic frequencies present in some passive pickups.
Bass: A boost here will add depth and weight to the sound of an instrument with light bass response. Cut the bass a few dB to tighten up the boomy tone of a dreadnought or jumbo guitar.
Middle: Two controls (level and frequency) make up this EQ circuit. The frequency control lets you tune in on a specific midrange frequency range which you can boost or cut.
Treble: This knob will help you cut through the mix, or conversely, mellow and subdue an already shrill tone.
The phase switch flips the polarity of your instrument signal from positive to negative, changing its relationship to the sound coming from the amplifier. One phase setting usually provides better resistance to feedback than the other and will vary depending on the instrument and playing environment.
The boost button initiates an increase in volume. The range of volume boost can be set from 3 to 12 dB using the boost wheel conveniently located next to the boost button.
