a
common
auxiliary
effect
loop, known
as
AUX2 on
the SM650,
and AUX
on the
SM550.
For

purposes,
this
loop
will be indicated
as AUX2
throughout
this
manual.
Owners
of
the SM550
should,
therefore,
relate
the
information
to their
AUX controls.
Any
reference to
0dBm
on control
dials assumes
that the
input
has been
cued
to the blue
OdB
