SLS

Speaker Line—Lightning Suppressor

No one knows when and where lightning will strike. But
with the Grommes~Precision SLS, 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 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 can help protect
electronic equipment from the much more likely induced strike.
Once the current flowing through the SLS exceeds its
switching current, the SLS clamps the transient voltage
simulating a short circuit condition. Once the current flowing
through the SLS is less than the devices holding current, the
SLS will reset, protecting your electronic equipment.

Simply locate the SLS 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 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 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.
