The Kepma AcoustiFex 2 preamplifier is a marvel of innovation for
Acoustic players who desire flexibility in acoustic sound and creative options when
playing on stage or acoustically. It was co-developed with X2 DOUBLE, a world
leader in innovative pickup designs. The AcoustiFex 2 System features onboard
effects that can be used when both unplugged playing acoustically, or when plugged
into an amplifier. This innovative preamp also is designed to enhance and refine
your tone when playing “unplugged” or with an amplifier or PA system. It features
an integrated tuner that mutes the output jack when engaged for silent tuning, a
mic blend control (body), master piezo volume, a tone shaping control plus built-in
Reverb, Delay and Chorus effects.
Operation
Unplugged — When playing acoustically, simply press and hold the volume button
for 2 seconds to power on the unit. You can adjust the effects coming from the
soundhole of the guitar to your taste using the controls on the panel. To power off
the unit, simply press the Volume button again and the green LED will go dim. The
AcoustiFex 2 will utilize the guitar body to increase its frequency response and the
guitar sound will be more resonant, solid, and dynamic. You can adjust the volume,
body & tone controls to suit your tone preferences.
Plugged in — When playing through an amplifier or mixing console, plugging into
the output jack will automatically power the unit on and disable the internal
transducer to eliminate any feedback.
Tuner — To activate the onboard digital chromatic tuner simply press and hold down
the lens of the tuner until it lights up. Doing so will mute the output jack until you
power the tuner off again.
Charging — The Kepma AcoustiFex 2 is powered by a lithium Ion 18650 long life
battery. Playing times will vary based on your situation, but the average time is up
to 25 hours. To charge the battery, simply plug the included type C USB cable into
the charging port on the front panel and connect the other end to a standard phone
charger. Expect longer charging times with this battery.
