A/B Relay Switch - Lexicon Vortex Manual De Uso

Vortex is equipped with an electrically iso-
lated analog switch that allows remote con-
trol of guitar amplifier lead/rhythm channel
selection. Simply connect a standard 1/4"
guitar cable between the Vortex rear panel A/
B relay switch and the A/B switching input on
your amp.
Both the front panel A/B button, and the
footswitch A/B control will activate this
switch, allowing you to simultaneously
switch effects and amplifier settings.
English
For example, if your amp channel A corre-
sponds to lead, and channel B to rhythm, you
can load Vortex's A registers with effects you
want to use on leads, and load the B registers
with rhythm effects. Now, a single tap on the
A/B footswitch will coordinate switching be-
tween lead effects on your A channel and
rhythm effects on your B channel.
