120V 60Hz 400W
P. POWER INPUT: Connect the included power cord in
accordance with the voltage and frequency ratings listed
on the rear panel of the amplifier.
Q. FUSE: Replace with same rating only.
R. POWER: Turns the amp ON-OFF. After turning the
POWER switch to ON, wait 30 seconds for the tubes to
warm up, then turn the STANDBY switch to ON to take
the amp out of STANDBY mode. Before turning the amp
POWER to OFF, place the amp in STANDBY by turning
this switch to OFF for 10 seconds before turning the
POWER to OFF.
S. STANDBY: Place this switch in the OFF position to put
the amp in STANDBY mode. This should be done when
taking a break from playing or before turning the amp
POWER to OFF as outlined above in the POWER section.

Using the STANDBY mode prolongs the life of the tubes
in the amp.
T. ADJUST BIAS: NOT USER SERVICEABLE—This feature
should only be used by an authorized service technician
to adjust the bias of the amplifier tubes.
U. EFFECTS LOOP: Useful for obtaining maximum perfor-
mance from rack-mount or pedal effects like Reverb,
Delay, Chorus, etc. Connect SEND to the input of your
effects unit and RETURN to the effect's output.
V. PREAMP OUT: Connect to another amp's EFFECTS
RETURN or POWER AMP IN for simultaneous multiple
amp use. This output may also be used to send the pre-
amp's signal directly to a mixer.
W. FOOTSWITCH: Connect the cable of the supplied
footswitch here (see item BB, EVH FOOTSWITCH, oppo-
site).
X. RESONANCE: Adjusts low-frequency response for each
channel respectively.

Y. BIAS TEST POINTS: NOT USER SERVICEABLE—This
feature should only be used by an authorized service
technician to adjust the bias of the amplifier tubes.
Z. LOAD IMPEDANCE: Selects the output impedance of
the amp (4, 8 or 16 ohms) to match the speaker load.
NOTE: The 5150-III 412 speaker enclosure (recommended)
has an impedance of 16 ohms. When using one 5150-III
412 speaker enclosure, set the LOAD IMPEDANCE switch to
"16Ω." When using two 5150-III 412 speaker enclosures, set
the LOAD IMPEDANCE switch to "8Ω."
AA. SPEAKER OUTPUTS: For connection to speaker
cabinet(s). When using one speaker cabinet, either jack
can be used. Use only a high-quality unshielded speaker
cable.
NOTE: A speaker must always be plugged into one of the
speaker jacks when the EVH amplifier is on or damage may
occur. Switch the amplifier "OFF" or to "STANDBY" while
changing speaker connections or impedance settings.
