Surge protection modules for outdoor speaker lines with multiple clamping voltages.
The LA Series provides three-stage surge protection for audio signal lines, guarding outdoor speaker installations against lightning-induced currents and catastrophic equipment damage. It is designed for performance venues and outdoor facilities needing reliable, inexpensive protection for speaker systems exposed to the elements and electrical surges.
Specialized surge protection modules for low-voltage audio and data signal lines. The L Series is engineered to safeguard sensitive AVL equipment connected via long or outdoor cable runs from lightning-induced electrical surges.

SIGNAL LINE PROTECTION
Protect outdoor audio equipment from lightning-induced surges.
Equipment installed outdoors, like speakers in stadiums or on light poles, provides an attractive path for lightning. A nearby strike can induce high current and cause catastrophic damage to connected audio equipment. The LA Series provides simple and inexpensive protection, diverting surges up to 5,000 amps in under a nanosecond.
Its hybrid, three-stage design combines fast-acting MOVs, inductors, and silicon avalanche diodes for robust protection. The modular design, which mates with a required PCB-1B base, allows for easy replacement of the protection module after a significant lightning event, simplifying long-term maintenance.
Choosing the correct LA model is critical for effective protection without impacting audio performance.
Clamping Voltage: Models are available with clamping levels from 15V to 150V.
Application Matching: The appropriate model is a function of the speaker’s impedance and wattage. For example, the LA 100 is designed for 70-volt speaker systems.
Guidance: Contact a LynTec engineer with your speaker specifications to determine the correct model for your project.
The LA Series uses a two-part system for easy installation and serviceability.
PCB-1B Base (Required): The protection module is not a standalone unit. It must be installed onto the PCB-1B mounting base, which is priced and sold separately.
Modular Connection: The LA module’s gold-plated circuit card securely mates with the base, allowing for quick and easy replacement when needed.
Yes. Each module can protect two pairs of lines up to 5 amps each. For higher current loads up to 10 amps, the terminals can be bridged to protect a single pair of lines.
The correct model depends on your speaker’s wattage and impedance, which determines the required clamping voltage. For example, the LA 100 model is for 70-volt systems. Contact a LynTec engineer with your speaker specs for a precise recommendation.
The module is designed to be easily replaceable. We recommend periodic inspection and replacement as part of a regular maintenance schedule, or immediate replacement following a known significant lightning event in the vicinity of the installation.
It’s a robust circuit design that uses three types of components in sequence: Metal Oxide Varistors (MOVs), inductors, and Silicon Avalanche Diodes (SADs). This provides more comprehensive protection against a wider range of electrical surges than a single-stage design.
