Community Distributed Design Series Installation and Operation Manual Page 20
Note: Here we describe wiring of the loud-
speakers in the cans, including connection to
the cans and between can and loudspeaker.
Because in some cases cans are installed first,
and the loudspeakers are installed immedi-
ately thereafter, whereas in other situations
the cans are pre-installed including the facility
wiring to the can, there is no “perfect” single
order in which to present these topics. We de-
scribe the actual mounting of the can into the
ceiling (or wall) after we describe the general
means to wire the cans and loudspeakers.
This manual will serve to assist in wiring and
physically mounting Distributed Design Se-
ries loudspeakers. The directions include as-
sistance to those installers using a complete
Community package of loudspeakers and ac-
cessories, including the back cans, grilles, tile
rails and so forth. We include instructions
for use of optional Community Distributed
Design Series retrofit adapters so that Com-
munity Distributed Design Series loudspeak-
ers can be mounted in other manufacturer’s
cutouts and/or back cans. If accessory
products from a different manufacturer are
used, please refer to the installation manuals
supplied with those products.
Wiring
Power Determination
As detailed subsequently, there is no need
to specially select different wire terminals
for 8-ohms or for various 70-volt and 100-
volt power taps. Instead, a face-mounted
tap switch allows you to make this selection.
Once the loudspeaker is mounted correctly
in the ceiling, set the tap switch to the appro-
priate tap setting before any audio is passed
through the loudspeaker. Do not change the
setting on the tap switch while the loud-
speaker is in use.
Installation in back cans without conduit
The only tool required is a screwdriver,
which is provided in the Loudspeaker
package. Distributed Design back cans
include a swivel-out terminal access cover
that also serves as a cable clamp when
tightened in place. The terminal block in the
can’s outer recess has two (+) connections
and two (-) connections. If you’re only
connecting one (dual conductor) cable,
you can use either (+) and (-) terminal,
as illustrated in Figure 20. If you’re daisy-
chaining a cable to the next can, you can
