Harman JBL Stadium 1224 User Manual

IMPORTANT: Make sure the
subwoofer amplifier is turned OFF before
setting the SSI switch. Do not change the
switch position while the subwoofer
amplifier is operating. Doing so could
damage the amplifier.
CONNECTING THE
AMPLIFIER
The subwoofer connectors are compatible
with bare or tinned wires. The
recommended wire gauge is between
14AWG and 8AWG, depending on the length
of the wire run between the amplifier and
woofer. Heavier gauge wire is preferred
for runs over 6'(2m).
1 .Use a 2.5 mm hex driver to open the
connectors
Z.lnsert the wire ends into the connector
openings
NOTE: If using untinned bare wire, be sure that
no stray "+"and "-"strands touch each other,
Touching strands can cause a short-circuit,
which can damage your amplifier,
3.Use the hex driver to secure the wires in the
connectors, as shown in the illustration
to the left
1. Use hex wrench to open connectors —
