Opus Technologies DCL20-K Counter & Reception Induction Loop Kit with Microphone
The Opus Technologies DCL20-K is a complete Counter and Reception Induction Loop Kit comprising the DCL20 loop amplifier, loop cable with RJ11 connections, external power supply and accessories — a ready-to-install hearing loop solution for reception desks, pharmacy counters, ticket windows and service points, compliant with IEC 60118-4.
The Opus Technologies DCL20-K is a complete induction loop kit designed specifically for counter and reception area installations — providing a straightforward, professional hearing loop solution for businesses and service providers who want to make their service points more accessible for customers and visitors who use hearing aids with a T-coil (telecoil) setting. The system transmits audio directly to compatible hearing aids, cutting out background noise, distance and room echo so that the listener hears speech clearly and comfortably at the service point — without the need to ask staff to repeat themselves or raise their voices.
Suitable for pharmacies, banks, GP surgery reception desks, ticket windows, hotel front desks, post offices and any other counter or service point where clear communication with hearing aid users is important, the DCL20-K provides everything needed for a complete installation in a single kit — with no separate components to source or additional equipment required for most counter installations.
IEC 60118-4 Compliant for Regulatory Confidence
The DCL20-K meets the requirements of IEC 60118-4 — the international standard for induction loop systems for hearing aid purposes — providing confidence that the system performs to the defined standard for field strength, frequency response and spillage. Under the Equality Act 2010, UK service providers are expected to make reasonable adjustments for people with disabilities, and fitting a hearing loop at a service counter is one of the most recognised and practical steps a business can take. Two “Adapted for Hearing Impaired Area” stickers are included in the kit to display at the counter, letting customers know the service is available.
DCL20 Loop Amplifier
The DCL20 is a compact, slim-profile loop amplifier measuring just 92 x 52 x 18mm — small enough to be installed discreetly beneath or behind a counter without taking up valuable workspace. The amplifier provides two inputs — a combined microphone/line input and a separate line input — with phantom power for condenser microphone connection, a built-in compressor with variable ratio from 1:1 to 20:1, automatic noise reduction and output protection including thermal, short-circuit and start protection. A functioning indicator confirms system status at a glance, and the resettable thermal fuse provides reliable long-term protection without the inconvenience of replaceable fuses. The DCL20 carries a 5-year manufacturer warranty.
