Using Speaker Selectors with IM
Muting Volume Controls
Although IM controls provide volume and on/off at
the volume-control location, they do not give you
central control of speakers playing throughout the
house. Speaker-selection systems give you central
control, but some speaker selectors have non-
defeatable impedance-protection circuits. Combining
IM controls with such a selector will reduce your
maximum volume substantially. To solve this problem,
specify a speaker selector with a defeatable
protection circuit (JobSite models S-4 or S-6). Then
keep the protection circuit off at all times.
