Using Speaker Selectors with IM
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.

Tightly twist the end of each wire until no frayed
