Rear Panel
All three Spitfire models offer the rear-panel features
described here:
Fuse
The fuse protects the Spitfire from damage caused by a
defective AC outlet. If this fuse blows, you must replace it.
Power Cord
Plug the power cord into an AC outlet. The AC voltage
required is fixed at a single voltage based on the country
in which you purchased your Spitfire. The voltage is not
switchable (i.e., 110/220) or universal (i.e., 90-240). Be
sure to connect it to the proper voltage as indicated in
the information found on the rear panel.
FOOTSWITCH UP/DOWN Inputs
Here you can plug in standard footswitches to use for
incrementing and decrementing program numbers. The
foot switches work in the same way as the Program Up
and Program Down buttons. These jacks accept 1/4”
plugs.
EXPRESSION PEDAL INPUT
This input is for an optional expression pedal, which
gives you the ability to control effect parameters with
your foot. All effects listed in chapter 10 that have
“Pedal” in their names provide this capability. See
chapter 10 for a complete list of parameters. This jack
CAUTION: Danger of
fire or electrocution
exists if the fuse is
incorrectly replaced.
Replace it only with the
same or equivalent type
of fuse recommended by
the information found
next to the fuse.
We recommend that you
purchase footswitches
to use with your
Spitfire. They aren’t
very expensive, and
they greatly streamline
your interaction with
the amplifier,
particularly when
playing live.

accepts a 1/4” plug. Expression pedals may be
purchased at your local Alesis dealer.
AUX (Auxiliary) INPUT
The AUX INPUT allows you to play along with your
favorite songs! Just connect this RCA input to the
output from your CD player, tape player or some other
external audio device. The AUX INPUT level is fixed,
but you can use the external audio device’s own volume
control (for example, the headphone volume control on
a portable CD player) to adjust the level of the signal
coming into these jacks. When you turn the MASTER
VOLUME knob, the level of this signal is affected as
well.
STEREO LINK OUTPUT
To take full advantage of the on-board stereo effect
processor, connect the STEREO LINK OUTPUT to
the input of a second amplifier to create a true stereo
setup. This jack accepts 1/4” TS cables.
SPEAKER OUTPUT
You can use the SPEAKER OUTPUT to connect the
Spitfire to an external 8-ohm speaker with a 1/4” TS
cable. This will disconnect the internal speaker.

The SPEAKER
OUTPUT is high-
voltage and can easily
damage normal
recording, PA, and
other line-level input
stages, so do not
connect this output to a
recording device, a PA
system, or the input of
another Spitfire.
Connect it only to an 8-
ohm speaker.
