How does one use the LG 120 to
model a loudspeaker’s dispersion
pattern?
The Variable Line Generator (LG 120)
can be used on any loudspeaker system
by either holding the unit flat against the
face of the loudspeaker or by using the
optional SA-S steel base plate that
allows for “hands-free” operation.
