System Installation Considerations
There are several factors to consider before installing Earthquake Sound’s
Shell Shoxx.
• What are the intended listening zones?
• What system options and accessories might be required for features such
as local sources, etc.?
• From where in each zone will the listener prefer to control the system? Where
will the remote gains be located? Where will the speakers be located?
• Where will the source equipment be located?
Connection Tips
• Keep all power cords away from all signal cables to prevent humming from
induced noise.
• Choose reliable signal cable cords (Earthquake Sound also specializes in
high-performance RCA cables and patches).
• All speaker wires that are ran through the walls should be twisted to reduce
potential hum noise pick up.
• Label both ends of all wires with the corresponding room location.
• It is best to use a grounded electrical outlet to power the amplifier. Lack of
input ground reference could be unsafe. Consult your electrical contractor
about proper grounding.
