Communications Systems | LBC 3428/00 Horn Loudspeaker
The Bosch LBC 3428/00 Horn Loudspeaker is specifically
designed for excellent sound reproduction in marine
applications and other industrial environments. It is
rugged, water- and dust-protected, and resistant to the
corrosive effects of seawater and most industrial
atmospheres. Suitable for both stationary and mobile
systems, its strength and good acoustic performance also
makes it ideal for general commercial and industrial
applications.

Functions
The Horn Loudspeaker is made from a UV-stable, glass-
reinforced polyester (GRP). This strong, fire-resistant and
corrosion- resistant material is very reliable and reduces
maintenance costs. GRP is also chemical resistant and
thermally stable, making it ideal for even the harshest
environments. The horns are weather-proof, and
incorporate stainless steel mounting brackets with cover
screws to increase corrosion resistance. They are fitted
with dual 20 mm gland entries (one gland is supplied as
standard) to facilitate loop-through connection.

Certifications and Approvals
All Bosch loudspeakers are designed to withstand
operating at their rated power for 100 continuous hours in
accordance with IEC 268‑5 Power Handling Capacity
(PHC) standards. Bosch has also developed the Simulated
Acoustical Feedback Exposure (SAFE) test to demonstrate
that they can withstand two times their rated power for
short durations. This ensures improved reliability under
extreme conditions, leading to higher customer
satisfaction, longer operating life, and lessens the chance
of failure or performance deterioration.

Installation/Configuration Notes
The Horn Loudspeaker includes a built-in transformer with
taps on the primary winding for different power settings.
The Horn Loudspeaker is supplied with a sturdy mounting
bracket allowing the sound beam to be accurately
directed. The bracket has a ratchet facility to ensure it
remains correctly positioned.
