Electro-Harmonix 44 Magnum Instruction Manual
44 MAGNUM
WARNING: USE ONLY THE 24 VDC / 3A ADAPTER THAT THE 44 MAGNUM
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 44 MAGNUM does not use batteries.
WARNING:
THE 44 MAGNUM IS A POWER AMP, NOT AN EFFECTS PEDAL. DO NOT
connect the output of the 44 MAGNUM to the input of another amplifier, effects
pedal, mixer, computer, computer interface or other similar device. Connect the
output of the 44 MAGNUM to an 8 -16 speaker cabinet ONLY.
Guitar Power Amplifier
Congratulations on your purchase of the
powerful 44 watts and is small enough to fit in the palm of your hand. Despite this amp’s small size, at 44
watts the 44 MAGNUM will have no problems being heard at the gig. The 44 MAGNUM’s sweet sound and
extreme portability guarantee it to be an integral part of your rig for rehearsal, recording, or playing out.
The 44 MAGNUM was designed with the guitar in mind and can be used alone, or with your favorite
preamp driving the input to the 44 MAGNUM. The 44 MAGNUM also sounds great with other instruments
such as bass and keyboard. Please read this manual to become familiar with the correct use of the 44
MAGNUM.
VOLUME CONTROL
VOLUME knob clockwise, the 44 MAGNUM’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 44 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.

impedance of the speaker cabinet must be rated between 8 and 16 ( = ohms). 8 is the ideal load
for the 44 MAGNUM. Additionally the speaker cabinet must have a power rating equal to or greater than
the 44 MAGNUM’s output power capability. We recommend a speaker cabinet with at least a 50W peak
rating (or 25W RMS).
WARNING:
Make sure the 44 MAGNUM’s output is connected to a speaker cabinet before applying power.

the power jack at the top of the unit. Only use the power supply that the 44 MAGNUM was supplied with.
The 44 MAGNUM requires a power supply capable of delivering at least 2A (more available current is
better) at exactly 24 VDC. DO NOT EXCEED 24 VDC ON THE POWER JACK, doing so will damage the 44
MAGNUM. DO NOT CONNECT AN AC POWER SUPPLY VOLTAGE TO THE 44 MAGNUM, USE DC POWER
ONLY. The polarity of the power jack is center positive.

powered up, the 44 MAGNUM may automatically mute its output to prevent a short circuit on the output
jack. In this situation simply remove power from the 44 MAGNUM, wait a few seconds and then re-apply
power to the 44 MAGNUM, it should work normally.
