The Trinity Preamp allows for perfect balancing of a microphone and a pickup/transducer. Channel 2 is a designated mic channel and supplies 9-volts to a lavalier type microphone. Each individual channel features volume, gain, +/- 20 dB bass, midrange, and treble filters. The EQ is accessible inside the box with trimpots. A convenient belt clip is included with this compact preamp, which weighs a mere ten ounces with the battery installed.
The Trinity Preamp is built with K&K's "Silent-Filter-Technology" using only full-size components. We use full size capacitors and transistors because we think that they sound better than the miniature components in most of today's guitar preamps.
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 on the outside of the box, one 1/4" stereo input (tip-pickup, ring-mic), a line level 1/4" mix output, and an optional 1/4" mic output that allows for splitting the two outputs for individual processing. Inside the box 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.
The Trinity Preamp has a Main/Mix Out which carries both channels (mixed), plus the option of individual channel outputs if a second cable is inserted in the center output.
