B6. Pull the speaker cable through the conduit coupler and
attach to the supplied Phoenix-type connector (8). This is a
4-position connector, with two “+” and two “–” terminals.
Connect the speaker cable to the “+” and “–” terminals
labeled
IN
. If connecting another speaker in a distributed
system (in parallel), connect the speaker cable running
to the next speaker to the “+” and “–” terminals labeled
LOOP THRU.
B7. Close the terminal cover plate
(7)
and tighten the locking
screw
(7a)
firmly.
B8. Insert the conduit into the coupler and fasten with the set-
screw.
Note:
A seismic safety tab
(10)
is provided to secure the
loudspeaker to the building structure with wire cabling for
additional support where required by local construction
codes. We recommend using this secondary support for
additional safety.
4. Set the Tap Selector Switch
(12)
. Make sure all the taps
in the system add up to less than the rated power of
the amplifier driving them. As a general rule, you should
provide at least 10% headroom to account for insertion
losses (i.e., wiring resistance, etc.). For example, if you
have four speakers tapped at 15 watts each, the amplifier
should be rated at least 66 watts.
5. Set the Full-Range/High-Pass Selector Switch
(13)
. For
normal operation, set the switch to the
FULL RANGE
position. If a subwoofer is being used in the system to
reinforce the very-low frequencies, use the
HIGH PASS
position to roll off the frequencies below 150 Hz. This
provides the added benefit of making more power available
for the crucial mid and high frequencies.
If the speaker is being used in a low-impedance system,
use the
FULL RANGE (16 OHM)
position. This
bypasses the tapped transformer.
6. Install the grille
(1)
by pressing it into place until the front
of the grille is flush with the front baffle rim. It is important
that the grille be securely seated to avoid having it vibrate
loose.
