To deliver a breathtaking performance, seamless integration of sound, lighting, and visual effects is essential. Behind every flawless presentation lies the critical role of display and connectivity solutions. As an emerging innovator in connectivity devices for audio-visual, lighting, automation, and communications, Seetronic continuously invest heavily in R&D and launching its latest SL4FXX-PRO 4-core professional loudspeaker audio connector. Specifically engineered for stage performances and AV engineering, this product centers on high reliability, exceptional audio transmission, and easy installation to meet the demanding requirements of the professional market for stability and efficiency.
Leveraging nearly two decades of manufacturing expertise, Seetronic has rigorously developed this product—from raw material research and structural design to precision engineering and nearly 10,000 specialized tests. Through repeated small-batch applications, it has achieved outstanding durability and stability, becoming the preferred choice for industry clients and technical engineers in stage lighting and automation.
I. Three Main Technological Innovations in Product Development
1·Signal Transmission and Anti-Interference Performance
Pure Copper Silver-Plated Pins: Utilizing copper substrate with ≥99.9% purity and a 3μm silver plating layer, significantly reducing contact resistance (≤0.5mΩ) to ensure low signal loss (<0.1dB@20kHz).
Electromagnetic Interference (EMI) Suppression Design: Optimized silver plating and shielding structure suppress ≥30dB of RF interference, suitable for high-density electronic environments.
2. Mechanical Structure and Durability
Mating Cycles: Zinc alloy housing + self-locking switch design, laboratory-tested for ≥1000 mating cycles (IEC 60512 standard).
Ergonomic Design: 15° angled receptacle supports blind insertion; textured surface enhances operational safety in humid conditions.
3. Environmental Adaptability
IP65 Protection Rating: Fully sealed structure resists dust and high-pressure water jets (tested per IEC 60529).
Wide temperature range support: Operating temperature range -40°C to +85°C, suitable for extreme outdoor environment.
II. Major Pain Points Addressed for Different Markets:
For Stage Performance Applications:
First, Rapid Deployment: Tool-free installation design enables one-handed operation, reducing equipment set-up time by ≥50%.
Second, Sound Quality Assurance: Silver-plated pins minimize high-frequency signal attenuation, with THD (Total Harmonic Distortion) <0.05%, meeting professional audio system requirements.
For engineering installation applications, it offers wire gauge compatibility:
Accommodates 1–4mm² audio cables without additional adapters. It also features lightweight design; housing made of high-strength engineering plastic (impact resistance ≥50kJ/m²), 40% lighter than metal housing.
Product meets international compliance standards, certified to IEC 61984 (connector safety standard) and RoHS 2.0.
This new 4-core loudspeaker connector (SL4FXX-PRO) represents the culmination of Seetronic’s 20 years of professional connector R&D expertise. Its three main technologies – silver-plated transmission, tool-free installation, and IP65 sealing – deliver a “zero-compromise” audio connection solution for stage performances, fixed installations, and outdoor projects.
As stated by Seetronic’s product manager, the SL4FXX-PRO is a rare professional audio connector that meets all IEC 61984 standards. It is the definitive choice for customers pursuing ultimate sound quality and ensuring equipment stability.
“From raw materials to final testing, we define product reliability through laboratory data.”
