K&K Sound Trinity Pro Product Manual

T RIN IT Y PRO PRE A M P
This 2-channel preamp is an extremely powerful yet
small mixer in a belt clip box. It is designed for
mixing a combination of a transducer and an
electret condenser microphone on one instrument to
achieve the best possible transmission.
It offers volume, gain, bass, mid, and treble controls
on each individual channel, and a phase switch on
the mic channel. The tone controls feature an
extended range of up to +/- 20 dB, which exceeds
many mixers on the market today. To keep the box
as small as possible, the gain and tone controls are
trim pots inside the unit (small potentiometers for
adjustment with a supplied tiny screwdriver).
During performance, the musician can conveniently
balance the two channels on the volume control
knobs.
Before first use, please insert a 9-volt battery. To
switch the battery off, always unplug the
MAIN/MIX OUT jack.
SETTING UP YOUR PREAMP
1. Remove the snap-off lid by simply lifting it
off. There is no need to undo any screws.
Important: Please do not tamper with the
screw on the bottom of the preamp!
2. Insert 9-volt battery into the designated
compartment.
3. There is a diagram for the internal trim pot
controls on the inside of the lid. In the box
you will find a little screwdriver for the
adjustment of the trim pots. It is attached
with a velcro fastener.
4. Connect your pickups to the stereo input via
a shielded ¼" stereo cable (not supplied)

and connect MONO/MIX OUT via a mono ¼"
guitar cable into an amplifier.
5. If a second mono cable is inserted into MIC
OUT, the channels will be carried
separately. In other words, MIC OUT will
carry only the microphone and MAIN/MIX
OUT will carry only the pickup. A cable must
be inserted in the MAIN/MIX OUT in order
to switch on the battery power.
6. Set your amp to a flat setting first. Our
preamps are shipped with a factory setting
that gets you started. Adjust the gain trim pot
the transducer channel. Adjust bass and
treble trim pots to your preference.
