Equipment installed outdoors and the cables that reach them can become effective conductors for surge energy produced from nearby lightning. Lightning need not make a direct strike to be destructive. Energy pulses induced into conductors during a lightning storm can cause significant damage to electronic gear.
Audio and data line surge protectors from Juice Goose can protect head end and remote equipment such as speakers, AV processors and amplifiers. Protection is available for either analog or digital components.
Outdoor audio lines can conduct power surges which damage speakers as well as signal source equipment and amplifiers. Certainly, a direct lightning strike to a speaker will be fatal for that speaker. But, lightning hitting any object nearby can induce an electromagnetic pulse into a speaker lead which will then seek ground through any path. Audio equipment on that path will be damaged. LA Series surge protectors conduct those surges to ground without touching connected equipment.
Data lines are conductors. Long runs of cable can become antennas for induced power surges from nearby lightning strikes. At risk are any equipment such as HDMI extenders. The Juice Goose LD-75 operates at high bandwidth data rates and voltages up to POE levels. With a connection to ground, this device safely diverts surges away from sensitive electronic equipment.
(This product is not currently available. Contact Juice Goose for additional information.) LA Series lightning protection for speaker lines. Equipment installed outdoors provides an attractive path for grounding lightning. Different LA Series models are best for different wattage and impedance applications. LA 100 for 70 volt speaker systems. Complete unit requires PCB-1B mounting base.
The LD-75 provides hybrid silicone avalanche diode surge protection for eight wire data circuits with high bandwidth communication rates and POE power up to 75V. It has been tested to a 1Gb transmission rate with a BERT error rating of 1.5%. It mounts to a stable flat surface and connects to building ground with a single RJ45 data line in and out.
