The Dual Channel Pro ST Preamp is a two-channel, beltclip mixer that allows you to blend two pickups. It is compatible with both piezo and magnetic pickups. The Dual Channel Pro ST 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 allows you to boost the input signal up to the 10-fold amount. It features two volume controls knobs, two 1/4" inputs, and a line level 1/4" output 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 for adjustment with a precision screw driver which is supplied). Once you installed the two systems you have chosen for your instrument, you can adjust them with 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.

This Dual Channel Pro ST version has a stereo input and 2 outputs: a main/mix plus individual channel outputs. Connect your pickups to the stereo input via a shielded 1/4" stereo cable (not supplied) and connect MONO/MIX OUT via a mono 1/4" guitar cable into an amplifier.
If a second mono cable is inserted into CH. 2 OUT, the channels will be carried separately. In other words, CH. 2 OUT will carry only Ch. 2 and MAIN/MIX OUT will carry only Ch. 1.
