44 MAGNUM
Guitar Power Amplifier
Congratulations on your purchase of the 44 MAGNUM guitar amplifier! The 44
MAGNUM produces a 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.
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 another similar device. Connect
the output of the 44 MAGNUM to an 8 -16 speaker cabinet ONLY.
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.
CONTROLS and JACKS
VOLUME CONTROL
This knob controls the volume or loudness of the amplifier. As you turn the
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.
BRIGHT/NORM CONTROL-
When engaged, the BRIGHT switch adds a subtle top boost or presence to your
signal. When in the NORM position, the top boost is defeated.
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.
8 16 OUTPUT Jack
Connect the 44 MAGNUM’s OUTPUT jack directly to a speaker cabinet. 8 – 16
only.
WARNING: NEVER CONNECT THE OUTPUT OF THE 44 MAGNUM 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 44 MAGNUM 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 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.
24VDC/3A POWER Jack Connect the output plug from the 44 MAGNUM’s supplied
power supply to 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.
WARNINGS (PLEASE READ!!!)
THE 44 MAGNUM IS A POWER AMP, NOT AN EFFECTS PEDAL:
Connect the output of the 44 MAGNUM to a speaker cabinet only. DO NOT CONNECT
THE OUTPUT OF THE 44 MAGNUM TO THE INPUT OF ANOTHER AMPLIFIER, EFFECTS PEDAL,
MIXER, COMPUTER, COMPUTER INTERFACE, or similar device.
SPEAKER CABINET:
Only plug the output of the 44 MAGNUM into a speaker cabinet rated for an
impedance in the range of 8 to 16 (8 to 16 ohms); the speaker cabinet power
rating should be 50W peak rating (or 25W RMS).
OUTPUT FIRST THEN POWER:
Connect the output of the 44 MAGNUM to a proper speaker cabinet before
applying power to the 44 MAGNUM. If you connect the 44 MAGNUM to a speaker
cabinet while it is 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.
