2 : HARDWARE OVERVIEW
RELAY 1, RELAY 2 (1/4” Tip-Ring-Sleeve Jacks)
Two fully-independent TRS relays allow the FX8 to switch the channels or other functions of a
connected amplier or other device. The state of each relay can be changed manually (via a footswitch)
or by a pre-programmed setting in a SCENE. See p Section 4 : The Relays for more.
PEDAL 1, PEDAL 2 (1/4” Tip-Ring-Sleeve Jacks)
These jacks are used to connect up to two external expression pedals or switches to control various
functions of the FX8. Use the PEDAL page in the I/O menu under SETUP to calibrate each connected
pedal. For more on using these jacks, see Connecting Pedals & Switches, p. 16.
USB – This provides the FX8 with two-way “MIDI-over-USB” capabilities.
The MIDI IN port of the FX8 allows you to control various MIDI functions of the FX8 including preset
and scene selection, eect bypass, X/Y changes, parameter changes, and more.
The MIDI page of the I/O menu under SETUP is used to congure MIDI Channel and other options (see
I/O: MIDI Page, p. 66.)
The MIDI OUT/THRU jack transmits Program Change, Control Change, and other MIDI data to
connected devices (such as an Axe-Fx II or an amplier with MIDI channel switching capabilities).
MIDI data can be sent manually using the MIDI Block, which is inserted like an eect assigned to a
footswitch (see “The MIDI Block” on page 42) or programmed to be sent automatically when you
select a Scene (see Section 7 : Scenes).
Main Power Input and switch – Insert the supplied power cable and connect the other end to
a grounded AC power receptacle. The FX8 has a universal power supply, which means it can be
connected to power around the globe simply by changing the cable. The main power switch is built in
to the receptacle.
We recommend switching the FX8 o when it will not be in use for an extended period of time.
