“When buying a used car, punch the buttons on the radio. If all the stations are
rock and roll, there's a good chance the transmission is shot.” Larry Lujack –

GENERAL OPERATION
The JCA20H is a single channel amplifier and does one thing
really well…it sounds good. Since it is a single channel amplifier
it is easy to operate. Here’s a general overview and some
suggestions for easy operation.
•
PREAMP: Adjust the amount of gain (distortion) that the
amplifier produces. The higher the preamp setting the more
overdriven the sound will be.
•
BASS, MIDDLE and TREBLE: allow you to control the tone.
•
VOLUME: will let you adjust how loud the amplifier will
sound.
•
PRESENCE: adds an overall brightness, which can be handy
when trying to cut through in a ‘dead’ room.
The JCA20H offers a far wider range of gain than most
amplifiers in its class. Its tonal character stretches from glassy
7
clean, to gritty edge, to modern high-gain. Please experiment
with your amp until you find the tone that suites your musical
styles and tastes.
“Among God's creatures two, the dog and the guitar, have taken all the sizes
and all the shapes, in order not be separated from the man” – Andre Segovia
AMPS, SPEAKERS AND IMPEDANCE
The JCA20H is designed for a 16ohm speaker. You may also operate this
amplifier in conjunction with additional speaker cabinets. An 8ohm or 16
ohm speaker cabinet will work fine with the JCA20H, but we do not
recommend using a 4ohm cabinet.
QUICK SETTINGS FOR SELECTED TONES
•
CLEAN SETTINGS: Set the VOLUME to 9 to maximize the
amplifiers extended headroom. Now simply use the PREAMP
control to achieve the desired tone and volume.
•
HIGH GAIN SETTINGS: Initially, the VOLUME should be set to a
low level (somewhere between 3-5) and the PREAMP turned up
to give the desired gain and distortion. Then return to the
VOLUME control to set the desired loudness.
•
REMEMBER TO EXPERIMENT: This is how you will get the most
out of your new amplifier.
