Electro Harmonix 5MM Power Amp User manual

WARNING: THE 5MM IS A POWER AMP, NOT AN EFFECTS PEDAL. Do not

connect the output of the 5MM to the input of another amplifier, effects
pedal, mixer, computer, computer interface or other similar device. Connect

the output of the 5MM to an 8 -16  speaker cabinet ONLY.

5MM

Guitar Power Amplifier

Congratulations on your purchase of the 5MM guitar amplifier! The 5MM produces
a formidable 2.5 watts and is small enough to fit in your pocket. The 5MM’s sweet
sound and extreme portability will make it an integral part of any rig where a high­powered amp is not required. The 5MM was designed with the guitar in mind and
can be used alone, or with your favorite overdrive or preamp driving the input to
the 5MM. The 5MM also sounds great with other instruments such as bass and
keyboard. Please read this manual to learn the correct use of the 5MM.

- CONTROLS and JACKS -

VOLUME CONTROL – This knob controls the volume or loudness of the

amplifier. As you turn the VOLUME knob clockwise, the 5MM’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 2.5 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 5MM’s OUTPUT jack directly to a

speaker cabinet. 8  – 16  only.

WARNING: NEVER CONNECT THE OUTPUT OF THE 5MM TO THE INPUT OF
ANOTHER AMPLIFIER, AN EFFECTS PEDAL, MIXER, COMPUTER, COMPUTER
INTERFACE OR OTHER SIMILAR DEVICE.

SPEAKER CABLE: We recommend using a speaker cable between the 5MM
and speaker cabinet as you would with any power amplifier, though you can get
away with using an instrument cable if in a pinch. The impedance of the speaker
cabinet must be rated between 8  and 16  ( = ohms). 8  is the ideal load
for the 5MM. Additionally the speaker cabinet must have a power rating equal to
or greater than the 5MM’s output power capability. We recommend a speaker
cabinet with at least a 10W rating.

POWER UP WARNING: Make sure the 5MM’s output is connected to a speaker
cabinet before applying power.

9VDC/500mA POWER Jack – Connect the output plug from the 5MM’s
supplied power supply to the power jack at the top of the unit. We highly
recommend using the power supply that the 5MM was supplied with. The polarity
of the power jack is center-negative.

- WARNINGS (PLEASE READ!!!) -

THE 5MM IS A POWER AMP, NOT AN EFFECTS PEDAL: Connect the output

of the 5MM to a speaker cabinet only. DO NOT CONNECT THE OUTPUT OF THE
5MM TO THE INPUT OF ANOTHER AMPLIFIER, EFFECTS PEDAL, MIXER,
COMPUTER, COMPUTER INTERFACE or similar device.

SPEAKER CABINET: Only plug the output of the 5MM 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 10W or greater.

OUTPUT FIRST THEN POWER: Connect the output of the 5MM to a proper
speaker cabinet before applying power to the 5MM. If you connect the 5MM to a
speaker cabinet while it is powered up, the 5MM may automatically mute its
output to prevent a short circuit on the output jack. In this situation simply
remove power from the 5MM, wait a few seconds and then re-apply power to the
5MM, it should work normally.
