K&K Trinity Preamp
The Trinity Preamp allows for perfect balancing of a lavalier type mic and a pickup/transducer. Channel 2 is a designated mic channel and supplies 9-volt to a lavalier type microphone (as opposed to the Dual Channel Pro ST Preamp, which features two pickup channels and does not supply mic power). Each individual channel features volume, gain, and +/- 20 dB bass, midrange, and treble filters. The EQ is accessible inside the box with trimpots. This belt clip preamp is an amazing unit for its price!
The Trinity Preamp is built with K&K’s “Silent-Filter-Technology” and our full size component philosophy. We use full size capacitors and transistors because we think that they sound better that the miniature components in most of today’s guitar preamps.
Aside from its strong bass, midrange and treble filters, it offers internal gain adjustments which set the pre amplification factor from 1 to 10 (for each channel). This way, you can boost the input signal up to the 10 fold amount. It features 2 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 2 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!
The Trinity Preamp has a Main Mix Out which carries both channels (mixed), plus the option of individual channel ouputs if a second cable is inserted in the center output. 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.
