The Rear Panel:
VFX5112/5212 Guitar Amplifier
18. AC Line Cord (not shown):
The grounded power cord should
only be plugged into a grounded
power outlet that meets all applica-
ble electrical codes and is compat-
ible with the voltage, power, and
frequency requirements stated on
the rear panel. Do not attempt to
defeat the safety ground con-
nection.
19. FOOTSWITCH JACK: Use
this jack to connect the cable of the
footswitch (supplied) for remote
control of channel switching and
the DSP effect. (Tip = channel
select, ring = DSP select.) Refer to
the section below for additional
information about how the
footswitch can be used to save
DSP settings fro each channel.
20. LINE OUT JACK: Use this
jack to send a line level signal from
the amplifier to an external amplifi-
er, a mixing console, or the input of
an external effect.
21. LINE IN JACK: Use this jack to
return the signal from an external
effect to the amplifier.
22. EXT. SPEAKER JACK: Use
this jack to connect the amplifier to
a 16 ohm extension speaker. The
internal speaker is not disconnect-
ed when this jack is in use. The
impedance switch (#23) must be
set to the 8 ohm position when a 16
ohm extension speaker is used.
23. IMPEDANCE SWITCH: Use
this switch to set the amplifier’s out-
put impedance to match the
impedance of the speaker(s). The
impedance of the speaker(s) inside
the amplifier is 16 ohms. The
switch is set at the factory to the 16
ohm position. When a 16 ohm
extension speaker cabinet is used
(see #22), this switch must be set to
the 8 ohm position. Use the tip of a
small flatblade screwdriver to slide
the switch to the proper position.

The two-button footswitch (supplied) may be used to save two DSP settings for each channel.
(1) Connect the cable of the footswitch to the Footswitch jack (#19) on the back of the VFX amplifier.
(2) Click the footswitch buttons until both LEDs are not illuminated. Channel A is now active.
(3) Select one of the DSP settings - for example, Large Reverb. Click the “EFFECTS A/B” footswitch
button (the EFFECTS A/B LED will illuminate). Select another DSP setting - for example, Vibrato
Slow. Click the “EFFECTS A/B” footswitch button again (the #EFFECTS A/B LED will go out) and
the Large Reverb DSP setting is recalled.
You have now programmed the footswitch to recall two DSP settings for Channel A: Large Reverb (CHAN-
NEL LED not illuminated) and Vibrato Slow (EFFECTS A/B LED illuminated). You may repeat this proce-
dure for Channel B. Click the “CHANNEL” footswitch button (CHANNEL LED illuminated), then repeat
step 3 for Channel B using different effects.
