to indicate if the amp channel assignment has been changed for
the Program Change message sent (if the amp channel assignment
has not changed, which would be the case when assigning amp
channel 1 to a Program Change message for the very first time, the
three amp channel LEDs will not all illuminate briefly because the
amp channel assignment has not changed from the default amp
channel 1 assignment).
If the Program Change message is currently assigned to amp chan-
nel 1 (default), you will have to press channel SELECT {E} twice to
select amp channel 2. If the Program Change message is currently
assigned to amp channel 2, you will have to press channel SELECT
{E} twice to select amp channel 1.
4 . Repeat steps 2–3 for each channel on the amp, if desired. You can
also assign multiple Program Change messages to the same amp
channel for more flexibility.
You can use the Footswitch to temporarily change channels at any
time during MIDI set up and it will have no effect on saving the amp
channel assignments. All channel assignment changes must be
made using the front panel channel SELECT buttons {E and I}.
5 . Once you are done setting up MIDI Program Changes, press both
channel SELECT buttons {E and I} simultaneously to exit "Learning
Mode." The amp is now set up to switch to the target channels
whenever the selected Program Change messages are sent on the
selected MIDI channel.
The default MIDI channel for the amp is channel 1. You can change
the MIDI channel for the amp by sending a Program Change mes-
sage from any other desired MIDI channel during Learning Mode.
The amp will then only respond to Program Change messages and
Control Change messages on that new MIDI channel.
To use MIDI for effects loop bypass:
1 . No set up is required. From MIDI channel 1 (default) or the channel
that was used to send Program Change messages in the section
above (if different from MIDI channel 1), simply send a Control
Change #85 message with a value of 63 or less to bypass the effects
loop or a value of 64 or more to enable the effects loop.
R . FOOTSWITCH—Connect the cable of the supplied footswitch
here. The footswitch allows easy selection of any of the three
channels as well as the effects loop. When illuminated, the Green,
Blue, and Red channel LEDs correspond with the channel LEDs on
the amplifier’s front panel.
ONE TWO THREE EFFECTS
S . EFFECTS LOOP—Connect SEND to effects input and RETURN to
effects output.
T . PREAMP OUT—Connect to another amp’s EFFECTS RETURN or
POWER AMP IN for simultaneous multiple amp use. This output
can also be used to send the preamp signal directly to a mixer.
U . RESONANCE—Adjusts the low frequency response of the power
amplifier.
V . LOAD IMPEDANCE—Selects the output impedance of the amp
(4, 8 or 16 Ohms) to match the speaker load.
NOTE: The 5150-III 212 speaker enclosure (recommended) has an impe-
dance of 16 Ohms. When using one 5150-III 212 speaker enclosure, set
the LOAD IMPEDANCE switch to “16Ω.” When using two 5150-III 212
speaker enclosures, set the LOAD IMPEDANCE switch to “8Ω.”
W . 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, included (P/N 0073411000).
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.
Speaker Configurations are as follows:
SPEAKER SPEAKER IMPEDANCE
JACK JACK SETTING
16Ω + NONE = 16Ω
16Ω + 16Ω = 8Ω
8Ω + NONE = 8Ω
8Ω + 8Ω = 4Ω
4Ω + NONE = 4Ω
