Whether you're at a bank teller window, pharmacy counter, ticket booth, government office, or information center, this system ensures staff and customers can hear each other clearly, eliminating the need to shout through the glass or repeat oneself. It's the ideal solution for smooth, professional interactions while maintaining safety and privacy on both sides of the counter.\u003c\/p\u003e\n\u003cp\u003eThe complete kit includes everything you need for instant clarity: separate customer-side surface-mounted speaker (STS-S60) and omnidirectional microphone (STS-M54) modules, a staff microphone and speaker unit with dual mute, a high-performance amplifier, and an under-counter hearing loop for customers using hearing aids. With its durable mild-steel construction and sleek powder-coated finish, it's designed for heavy daily use in busy public environments. And because it's pre-engineered for plug-and-play setup, you can have it up and running quickly without complicated configuration.\u003c\/p\u003e\n\u003cp\u003eBehind the scenes, the STS-K002 uses advanced technology to ensure high-quality sound and reliable operation. The cardioid staff microphone and omnidirectional customer microphone capture speech clearly, while the precision-tuned amplifier delivers crystal-clear audio on both sides of the barrier. The integrated hearing loop makes it fully accessible, and the low-profile surface-mount design keeps the customer counter unobstructed for a clean sightline. Reliable, efficient, and ADA-friendly, this is the professional standard for modern service counters.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFAQS:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the difference between the STS-K002 and the Bridge Bar STS-K001?\u003c\/strong\u003e\u003cbr\u003eA: Both kits provide the same two-way audio and hearing loop functionality. The STS-K002 uses separate customer-side speaker (STS-S60) and microphone (STS-M54) modules that sit directly on the counter for a lower profile and unobstructed sightline.
