Electro-Voice NL-4S Inductive Neckloop

The Electro-Voice NL-4S Inductive Neckloop is a professional-grade assistive listening accessory designed to connect directly to public address systems, amplifiers, or media players and deliver crystal-clear sound to telecoil-equipped hearing aids and cochlear implants. Built for reliability in professional environments—churches, theaters, conference rooms, classrooms, and broadcast venues—this neckloop creates a comfortable, personal audio field that isolates speech from background noise. Its compact, low-profile design sits comfortably around the neck, delivering a stable coil field that works with most telecoil-equipped devices. The NL-4S is crafted to minimize interference, maximize intelligibility, and offer a dependable listening experience across a wide range of listening scenarios. If you need a discreet, straightforward way to access amplified sound without bulky receivers or external batteries, the NL-4S is a trusted choice for professionals and individuals seeking clear, natural sound in public spaces or personal settings.

• Telecoil compatibility for effortless listening — The NL-4S is engineered to work with hearing aids and cochlear implants that feature a telecoil (T-coil). By converting the public address system’s audio into an inductive signal, the neckloop delivers focused, audible speech directly to the user’s hearing device, dramatically reducing ambient noise and improving comprehension in challenging acoustic environments such as worship services, lectures, and meetings.
• High-quality audio transfer with minimal distortion — The inductive loop is designed to preserve speech clarity and preserve natural tonal nuances. Whether the venue presents spoken-word content, music, or multi-speaker presentations, the NL-4S offers a stable field strength and clean signal transfer that helps listeners catch every word, phrase, and inflection with less effort and fatigue.
• Comfortable, unobtrusive wear for all-day use — The neckloop’s low-profile, lightweight construction rests softly around the neck, remaining unobtrusive under clothing or collars. Its design supports long listening sessions in crowded spaces, making it ideal for worship services, conferences, classrooms, or broadcast studios where mobility and comfort are essential.
• Simple setup and broad compatibility — The NL-4S can be used with a wide range of audio sources, including wireless systems, audio mixers, laptops, tablets, and smartphones when paired with the appropriate adapters. Its passive coil requires no power supply, so there are fewer cables to manage and fewer points of failure in busy environments. This makes it a versatile solution for venues that host diverse events and audiences.
• Professional build quality for demanding environments — Electro-Voice designs the NL-4S with durable materials and robust construction to withstand daily use in high-traffic settings. The coil, housing, and connectors are built to resist wear, with shielding and construction focused on minimizing hum and electromagnetic interference, ensuring reliable performance even in complex electrical environments.

• Power and operation: Passive device; does not require external power or batteries. Relies on the audio signal’s power to generate the inductive field for the user’s telecoil-equipped device.
• Applications: Suitable for a wide range of environments where discreet, direct-to-telecoil listening is beneficial, including worship centers, conference rooms, lecture halls, and performance venues.

How to Install Electro-Voice NL-4S Inductive Neckloop

• Power on or prepare the audio source you’ll connect to the neckloop. Ensure the source is producing sound at a clear, moderate level for testing.
• Place the neckloop around your neck with the coil facing outward toward the hearing aid or telecoil-equipped device. Adjust position for best pickup, typically close to or around the throat area where the magnetic field is strongest for the user.
• Connect the NL-4S to your audio source using the appropriate cable or adapter that matches the venue’s audio output. For example, connect to a mixer’s line-out, a portable audio player, a computer, or a wireless microphone system using standard audio connectors as required by your setup.
• Activate the telecoil mode on your hearing aid or cochlear implant processor. If you’re unsure how to enable telecoil, consult your device’s user manual or ask the venue staff for assistance with telecoil activation.
• Begin playback and listen for a clear, direct audio signal. If the sound is faint or noisy, reposition the neckloop slightly and adjust the audio source’s output level to achieve a balanced, intelligible signal without distortion.

Frequently asked questions

• What is the Electro-Voice NL-4S Inductive Neckloop used for? It’s a professional, passive inductive neckloop designed to deliver audio to telecoil-equipped hearing aids and cochlear implants from public address systems, media players, or other audio sources, enabling clearer speech in public spaces and at home.
• Is the NL-4S compatible with all hearing aids? The NL-4S is compatible with hearing aids and cochlear implants that include a telecoil (T-coil). Always verify that your device supports telecoil input and test the neckloop in the intended environment to ensure optimal performance.
• Do I need batteries or power for the NL-4S? No. The NL-4S is a passive inductive neckloop; it does not require batteries or an external power source. It derives its audio field from the connected audio source.
• Can I use the NL-4S with a smartphone or computer? Yes, with the appropriate adapter or cable to connect the audio output of the device to the neckloop’s input. Ensure the audio source can drive the neckloop’s coil adequately and that telecoil mode is enabled on your hearing device.
• How do I optimize performance in a crowded venue? Position the neckloop so the coil is near your hearing device’s telecoil, and increase the audio source’s level moderately if needed. Reduce ambient noise where possible and test a quick audio sample before a full event.
• Is the NL-4S suitable for music listening as well as speech? While primarily optimized for speech intelligibility in public-address scenarios, the NL-4S can reproduce musical content when connected to suitable audio sources. Realize that the primary benefit is improved speech clarity through telecoil devices in environments where listening to the PA system is essential.
