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.

INSTALLATION
1. Identify the speaker wire and amplifier wire.
Label the wires for future reference.

Tightly twist the end of each wire until no frayed
ends remain.
3. Locate the snap and lock connectors and remove
them if they are plugged in.
