K&K Dual Channel Pro ST Preamp
Dual Channel Pro Preamp with stereo input and two outputs, main/mix and individual channels.
The Dual Channel Pro Preamp is a two-channel, belt clip mixer that allows you to blend two pickups. It is compatible with both piezo and magnetic pickups. The Dual Channel Pro Preamp features extremely low-noise operation. It can process high input peaks without distortion and offers an incredible dynamic range.
Aside from its strong bass, midrange, and treble filters (for each channel), it offers internal gain adjustments which set the pre-amplification factor from 1 to 10 (per channel). This means you can boost the input signal up to the 10-fold amount. It features two volume controls knobs, one stereo 1/4" input, and two line level 1/4" outputs (a main/mix out and individual channel outputs) on the outside of the box. Inside the box, there are adjustable controls for gain, bass, midrange, and treble for each channel. The tone controls offer an incredible +/- 20 dB. This is a wider range than some big boards on the market today!
To keep the box as small as possible these controls are trim pots (small potentiometers that can be adjusted with the supplied precision screw driver). Once you've installed both pickups, you should adjust the trim pots to your personal taste and needs. During performance, the two volume knobs on the outside allow for fast balancing on the fly.
