Cautions and Maintenance (Continued)
For environments that get snow and ice during the winter months, be sure to check that the openings and woofer cone are
clear and there is no hard-packed snow or ice built up in these areas before playing. If there is ice or snow present on the
cone, use a hair dryer set on a low setting to to melt it away. If the speakers are not going to be used during winter months,
it is recommended that they either be disconnected and brought indoors, or covered with a plastic bag to help protect the
speaker components.
Wiring for Low Impedance Applications
If using 8 ohm wiring instead of 70V, only use tap position 1 on Periscape units. Subscape units require specific preparation for
8 ohm use, outlined in step 5 of the Subscape instructions section. Use the supplied silicone wire nut to connect the positive
(+) leads of the speaker and input wires. Repeat this step with the negative (-) leads. Rockustics recommends using 14ga or
heavier direct burial cable for the connection between the amplifier and the speakers.
Wiring for 70V/100V Applications
For speakers with transformers, use
Diagram C and D
to find the proper wire selection for your desired tap setting. Once
the desired tap setting is confirmed, trim the unused wires to minimize corrosion. For harsh and wet environments, it is
recommended to apply a bead of silicone to the end of the unused wires for added protection.
If daisy-chaining, follow wire preparations as outlined in the
Basic Wiring
section. Review
Diagram F
for a typical daisy-chain
wiring system for 70V and 100V applications. Be sure to connect the wires going to the next speaker in the chain as shown
in
Diagrame E
. There should be three pairs of wires at each speaker, but the last speaker in the chain will only have two pair.
Follow standard protocol for polarity and make sure all units are wired with the same polarity.
