Audix NovaCore NCHHTH Handheld Transmitter - Tight Hypercardioid

The Audix NovaCore NCHHTH is a complete digital handheld wireless solution that pairs the NCHH transmitter body with the NCTH tight hypercardioid capsule. Designed for loud stages and high-SPL environments, it delivers exceptional gain-before-feedback, precise pickup control and secure, low-latency UHF digital transmission, making it ideal for vocalists, presenters and engineers who need rock-solid performance night after night.

With AES-256 encryption, a generous 48 MHz tuning range and latency under 3 ms, the NCHHTH is built for modern, interference-prone RF environments. On-board controls give you detailed control over input gain, low-cut filtering, limiting, RF power and mute behaviour, while the tight hypercardioid capsule offers the focused, natural sound and transient response that Audix capsules are renowned for.

Power flexibility is another major strength. Run the transmitter on standard AA alkaline batteries or the optional NCLB rechargeable lithium-ion battery, with over 9 hours of runtime and convenient USB-C charging built directly into the body. The standard S-thread capsule mount also means you can quickly swap to an NCEC extended cardioid capsule if your application changes, without tools or downtime.

Tight Hypercardioid Capsule for Loud Stages

The included NCTH tight hypercardioid capsule is voiced from the Audix OMX series and optimised for maximum feedback rejection. Its narrow pickup pattern focuses on the source while aggressively rejecting off-axis sound, helping you keep vocals clear and controlled even on cramped, high-volume stages. The natural transient response captures detail and articulation, so performances cut through the mix without sounding harsh.

Secure, Low-Latency UHF Digital Transmission

The NCHH transmitter delivers UHF digital audio with AES-256 encryption across a 48 MHz tuning range. This combination provides robust, secure transmission in busy RF environments, making it suitable for professional touring, corporate and live production work. With latency under 3 ms, performers experience an immediate, responsive feel that keeps monitoring and timing tight.

Comprehensive On-Board Control

Front-panel LCD feedback and controls beneath the battery cover give you direct access to variable input gain, a low-cut filter, limiter, RF output power and three selectable mute modes. This lets you tailor the system to different performers, venues and PA setups without relying on external processing, helping you maintain consistent sound and avoid unwanted noise or handling artefacts.

Flexible Power and Capsule Options

The NCHHTH runs on either 2 x AA alkaline batteries or a single NCLB rechargeable lithium-ion battery, offering more than 9 hours of runtime for long events and multi-set shows. Built-in USB-C charging adds convenience for rechargeable workflows. The standard S-thread mount allows the NCTH capsule to be swapped for an NCEC extended cardioid capsule at any time, so you can adapt the microphone behaviour to different stages and performers with minimal effort.

• NCTH Tight Hypercardioid Capsule - The tight hypercardioid pickup pattern delivers strong gain-before-feedback and narrow off-axis rejection, ideal for loud stages and high-SPL environments. Voicing derived from the Audix OMX series provides a familiar, musical sound with the fast transient response that helps vocals stay clear and intelligible.
• AES-256 Encrypted UHF Digital Transmission - AES-256 encryption combined with a 48 MHz tuning range (494 to 542 MHz) and latency under 3 ms ensures secure, stable and responsive wireless performance. This makes the system well suited to professional live sound, broadcast and corporate applications where reliability and privacy are essential.
• Configurable RF Power and Mute Modes - Switchable RF output at 1 mW or 10 mW lets you optimise range and battery life for different venues and stage sizes. Three selectable mute modes (Standard, Auto and Bypass) provide flexible control over how the mute switch behaves, helping engineers manage noise and transitions between songs or speakers.
• Flexible Power and Interchangeable Capsule Mount - Operate the transmitter using 2 x AA alkaline cells or a single NCLB rechargeable lithium-ion battery, with over 9 hours of runtime and convenient USB-C charging built in. The standard S-thread capsule mount allows quick, tool-free swapping to an NCEC extended cardioid capsule whenever a different pickup pattern is required.
