22 CALIBER

Guitar Power Amplifier

Congratulations on your purchase of the

22 CALIBER

guitar amplifier!

The 22 CALIBER is a 22 Watt

power amplifier for guitar that fits in the palm of your hand. Its excellent tone and extreme portability will

guarantee it to become a mainstay for performance, rehearsal or recording. The 22 CALIBER delivers

everything that you would expect in a much larger amplifier. Though the 22 CALIBER’s input and gain

structure was optimized for guitar it will work great with other instruments as well. Please read this manual

to become familiar with the correct use of the 22 CALIBER.

-CONTROLS and JACKS-

VOLUME Knob

–Controls the volume or loudness of the amplifier. As you turn the VOLUME knob

clockwise, the 22 CALIBER’s output gets louder. At a certain point in the VOLUME knob’s travel the output

will start to overdrive, at this point you are beginning to exceed 22 Watts on your loudest notes. Turning

the VOLUME knob further clockwise will produce a more overdriven sound which is the result of pure

power amp saturation.

BRIGHT Switch

When engaged the BRIGHT switch adds a subtle high end boost or presence to your

output signal. When in the normal position it is defeated yielding a signal that passes from input to output

uncolored.

WARNING: USE ONLY THE 18 VDC / 1.66A ADAPTER THAT THE 22

CALIBER COMES SUPPLIED WITH. Do not use any other adapters. Using

other adapters, even those made by Electro-Harmonix, could cause harm

to the unit, the adapter or you. The 22 CALIBER does not use batteries.

WARNING:

THE 22 CALIBER IS A POWER AMP, NOT AN EFFECTS PEDAL.

Do not

connect the output of the 22 CALIBER to the input of another AMPLIFIER, EFFECTS

PEDAL, MIXER, COMPUTER, COMPUTER INTERFACE or other similar device.

Connect the output of the 22 CALIBER to a speaker cabinet only.

INPUT Jack

Plug the output of your guitar, effects pedals or any other instrument into the INPUT jack

using a standard ¼” instrument cable. The input impedance presented at the INPUT jack is 2 M



4 –16



OUTPUT Jack

–

Connect the 22 CALIBER’s OUTPUT jack directly to a speaker cabinet.

WARNING:

NEVER CONNECT THE OUTPUT OF THE 22 CALIBER TO THE INPUT OF ANOTHER

AMPLIFIER, AN EFFECTS PEDAL, MIXER, COMPUTER, COMPUTER INTERFACE OR OTHER SIMILAR

DEVICE.

We recommend using a

speaker cable

between the 22 CALIBER and speaker cabinet as you would with

any power amplifier, though you can get away with using an instrument cable if absolutely necessary. The

impedance of the speaker cabinet must be rated between 4



and 16



(



= ohms). 8



is the ideal load

for the 22 CALIBER though it will work into loads ranging from 4



to 16



. Additionally the speaker

cabinet must have a power rating equal to or greater than the 22 CALIBER’s output power capability. We

recommend a speaker cabinet with a 30 W rating.

WARNING:

Make sure the 22 CALIBER’s output is connected to a speaker cabinet before applying power.

18VDC/1.5A POWER Jack –

Connect the output plug from the 22 CALIBER’s supplied power supply

to the power jack at the top of the unit. Only use the power supply that the 22 CALIBER was supplied with.

The 22 CALIBER requires a power supply capable of delivering at least 1.5 A (more current is better) at

exactly 18 VDC. DO NOT EXCEED 18 VDC ON THE POWER JACK, doing so will damage the 22 CALIBER.

DO NOT CONNECT AN AC POWER SUPPLY VOLTAGE TO THE 22 CALIBER, USE DC POWER ONLY. The

polarity of the power jack is center positive.

-WARNINGS (PLEASE READ!!)-

THE 22 CALIBER IS A POWER AMP, NOT AN EFFECTS PEDAL:

Connect the output of the 22

CALIBER to a speaker cabinet only. DO NOT CONNECT THE OUTPUT OF THE 22 CALIBER TO THE INPUT

OF ANOTHER AMPLIFIER, EFFECTS PEDAL, MIXER, COMPUTER, COMPUTER INTERFACE or similar device.

SPEAKER CABINET:

Only plug the output of the 22 CALIBER into a speaker cabinet rated for an

impedance in the range of 4



to 16



(4 to 16 ohms).

OUTPUT FIRST THEN POWER:

Connect the output of the 22 CALIBER to a proper speaker cabinet

before applying power to the 22 CALIBER. If you connect the 22 CALIBER to a speaker cabinet while it is

powered up, the 22 CALIBER may automatically mute its output to prevent a short circuit on the output

jack. In this situation simply remove power from the 22 CALIBER, wait a few seconds and then re-apply

power to the 22 CALIBER, it should work normally.
