LA Series
Equipment installed outdoors are effective antennae for power impulses created by lightning. Speakers mounted in stadiums,
on light poles, on tops of buildings or on the ground are great examples. Amplifiers and other audio source equipment in the
energy surge’s path to ground often suffer the greatest damage in such events. Even lightning striking near an audio installation can induce high current into speaker leads and cause catastrophic damage. Protecting that equipment is simple and
inexpensive with LA Series surge protectors from Juice Goose.
LA Series models are designed to protect two pairs of speaker leads (four wires). The mounting
base (Item PCB-1B, sold separately) also has a connection for a ground wire. The unit is rated
for operating currents up to five amps (350 watts at 70 volts) for each of two wire pairs. For
higher current requirements terminals may be bridged to protect a single pair of speaker leads
with maximum current up to ten amps. The LA Series includes models designed for various peak
voltages from under 15 to 100. (See the LA Selection Chart for additional information.)
The LA Series is designed with three stage component protection - varistors (MOV), wire wound inductors
and silicone avalanche diodes (SAD) - to provide sub nanosecond response to surges up to 5,000 amps.
This design is tuned to have ultra low impedance of only 0.02 ohms per wire pair.
