The DCL20-65 is a fully equipped induction loop kit designed to enhance speech transmission and accessibility within service environments that utilise window intercom systems. Developed for professional use in sectors such as transport, banking, healthcare, and public services, the DCL20-65 supports communication for individuals with hearing impairments through an integrated audio-frequency induction loop system. The inclusion of the DCL20 amplifier ensures consistent audio output, while the OP-iL loop enables users with hearing aids or cochlear implants set to the T-position to receive clear sound directly to their device. Supplied with a dedicated power supply, Phoenix connector, screwdriver, and adhesive stickers, the DCL20-65 offers all essential components for straightforward installation and configuration. Its design supports compliance with accessibility regulations and is particularly suitable for high-traffic customer service points, such as ticket counters, information desks, and reception areas. By ensuring that audio communication is clearly transmitted through glass partitions or acoustic barriers, the DCL20-65 helps service providers maintain clear dialogue with all visitors. This complete kit has been engineered to deliver reliability, durability, and compatibility with a wide range of existing intercom systems, making it an essential solution for organisations aiming to improve accessibility and service efficiency in face-to-face interactions.
