Speaker Line—Lightning Suppressor

For High Wattage Systems

No one knows when and where lightning will strike. But
with the Grommes~Precision SLS-HW, you can rest easy in
knowing that the majority of the reason electronic equipment
gets damaged from lightning striking the speaker line can now
be eliminated inexpensively!

Most lightning damage to electronic equipment is caused
through induction. With induction, lightning does not strike the
speaker line or electronic equipment directly, rather, it propels,
or induces, large voltages of electrical energy into the system.
Equipment connected to long speaker lines are especially
susceptible to damage from induction.

Therefore, Grommes~Precision designed the SLS-HW to
prevent induced speaker line lightning surges from harming
the electronic equipment connected to it. Although not much
can withstand the rare direct strike, the SLS-HW can help
protect electronic equipment from the much more likely
induced strike. Once the current flowing through the SLS-HW
exceeds its switching current, the SLS-HW clamps the
transient voltage simulating a short circuit condition. Once the
current flowing through the SLS-HW is less than the devices
holding current, the SLS-HW will reset, protecting your
electronic equipment.

Simply locate the SLS-HW within the speaker line directly
after the electronic equipment to protect the equipment, or
directly before the speaker to protect that speaker or speaker
cluster. The SLS-HW is a small component that is easy and
inexpensive to integrate into a new or existing system and will
provide peace of mind should lightning strike.

And, with over a half-century of experience in the business,
Grommes~Precision’s SLS-HW is made in America, and is
backed by Grommes~Precision’s unbeatable expertise and
Assurance Policy: a 5 year warranty and 30 Day Money

Back Guarantee.
