Shure ADX2/N8CB – Nexadyne Cardioid Handheld Transmitter, Black

Product Overview

The Shure ADX2/N8CB Axient Digital handheld transmitter pairs the Nexadyne 8/C cardioid capsule with Shure's flagship Axient Digital wireless platform, giving integrators a broadcast-grade wireless microphone system for demanding commercial AV deployments. The black-finish capsule uses Revonic dual-engine transducer technology to deliver natural vocal clarity with strong off-axis rejection, making this a dependable choice anywhere a single, consistent presenter or vocal mic matters. It is built for commercial AV wireless microphone deployment where RF reliability and clean audio integration into an existing Dante or analog signal chain are non-negotiable. Houses of worship, broadcast studios, and auditoriums needing a house-owned handheld wireless microphone system will find the ADX2/N8CB a straightforward fit alongside existing Axient Digital receivers.

Product Description

The ADX2/N8CB is part of Shure's Axient Digital wireless microphone system, engineered for AV integrators who need predictable RF behavior across large, RF-congested venues. The Nexadyne 8/C cardioid capsule replaces the aging Beta-series capsules with a dual-transducer Revonic design that reduces the need for corrective EQ while tightening off-axis rejection — a practical benefit in rooms with in-ceiling loudspeakers and floor monitors where gain-before-feedback is a real constraint. Wide tuning bandwidth (up to 184 MHz depending on band) gives system designers room to coordinate frequencies against IEMs, other wireless mics, and RF from broadcast trucks or house networks.

Onboard ShowLink remote control lets an AV technician or FOH engineer adjust gain, mute, RF output power, and frequency from a distance, without walking a transmitter back to a work table mid-event. Automatic interference avoidance further reduces the chance of an on-air or mid-service dropout. Two selectable transmission modes — Standard for maximum coverage and High-Density for maximum channel count — let the same hardware serve either a single-mic sanctuary install or a densely packed broadcast RF environment. Power comes from the SB920A rechargeable lithium-ion battery, rated for up to 9 hours of runtime in single-carrier mode, with external charging contacts for dock-based recharging between services or shows. The black anodized aluminum housing is moisture-resistant and built to handle repeated handling, touring cases, and daily commercial use, with lockable controls and a backlit LCD that keeps status information visible to the operator without opening a menu tree.

Frequently Asked Questions

Is the ADX2/N8CB compatible with existing Axient Digital receivers?
Yes. The ADX2/N8CB is designed to operate with Shure Axient Digital receivers, including the ADX5DUS-A dual-channel slot-mount receiver. Confirm both units share a compatible frequency band before ordering.

What is the difference between the N8CB and N8CN versions?
Both use the same Nexadyne 8/C cardioid capsule and Revonic transducer technology. The N8CB ships in a black finish; the N8CN ships in a nickel finish. Electronic performance is identical between the two.

How is this different from the supercardioid version?
The cardioid Nexadyne 8/C capsule used here provides a wider pickup angle than the supercardioid Nexadyne 8/S used in the ADX2/N8SB, which is better suited to tighter rejection needs on louder stages.

Does installation require an RF coordination plan?
For single-mic deployments in a small sanctuary or meeting room, minimal coordination is needed. For multi-channel commercial AV installs, we recommend frequency coordination software and, where available, pairing with a ShowLink access point for centralized remote control.

What charging accessories are compatible?
The SB920A battery is compatible with Shure's networked and rack-mount charging systems designed for Axient Digital and ADX2 transmitters, allowing multi-unit charging in touring cases or equipment racks.

What is the warranty on this transmitter?
The ADX2/N8CB carries Shure's standard manufacturer warranty for professional wireless products. Contact Creation Networks for warranty registration and service support specific to your order.

Can this transmitter be used in a multi-channel commercial AV system?
Yes. High-Density transmission mode is specifically designed to increase usable channel count in systems with many simultaneous handheld and bodypack transmitters, common in auditoriums and broadcast studios.

Is technical support available for AV integrators?
Creation Networks provides pre-sale system design support and can help confirm frequency band compatibility with existing receivers before you order.
