Shure AD4DNPTA=-A Axient Digital Two-Channel Wireless Receiver with No Accessories (A: 470 to 636 MHz) (TAA-Compliant)

Product Overview

The Shure AD4DNPTA=-A is a TAA-compliant, two-channel Axient Digital wireless receiver for commercial AV deployments requiring professional-grade wireless audio in government facilities, broadcast studios, and large-scale commercial meeting environments. Operating in Band A (470–636 MHz), this rack-mount receiver integrates natively with Dante-enabled audio networks and supports AES3 and AES67 digital outputs for direct connection to IP-based AV infrastructure. The -NP designation means the receiver ships without a power supply or mounting accessories — the correct choice when adding capacity to an existing Axient Digital rack where AC power is already distributed via locking cascade connections.

Product Description

The AD4D supports two independent wireless audio channels in a single 1U rack space. Band A covers 470–636 MHz, giving AV system designers substantial spectrum to work with in frequency-dense environments. High Density (HD) mode compresses channel spacing to 125 kHz, enabling up to 47 simultaneous active transmitters within a single 6 MHz TV channel — directly addressing the channel count demands of legislative chambers, convention centers, and multi-room corporate campuses. AES-256 encryption is applied across all channels, satisfying audio security requirements for federal government spaces and secure boardrooms. The AD4DNPTA=-A is compatible with all Shure AD and ADX series transmitters, allowing integrators to mix handheld, bodypack, boundary, and gooseneck transmitters within the same system. For installations requiring four channels in a single rack unit, see the Shure AD4Q-DCTA=-A Four-Channel Receiver.

Key Features

• Two Independent Wireless Channels in 1U — Supports two simultaneous wireless microphone channels from a single rack unit, preserving rack space in commercial AV system builds.
• Band A: 470–636 MHz Tuning Range — Broad spectrum coverage in Band A for frequency coordination across multi-channel wireless deployments in RF-dense environments.
• High Density (HD) Mode — Narrows channel spacing to 125 kHz, supporting up to 47 active transmitters per 6 MHz TV channel for high-channel-count installations.
• Dante, AES3, and AES67 Digital Audio Outputs — Native integration with Dante-enabled IP audio networks and AES3/AES67 digital signal paths, compatible with leading DSPs and mixing platforms.
• AES-256 Encryption — Applies government-grade encryption to all wireless audio channels, meeting security standards for federal facilities and secure commercial spaces.
• Interference Management with Automatic Frequency Switching — Detects RF interference on active channels and can automatically switch to a clean frequency, reducing dropout risk in congested spectrum.
• 60 dB Gain Adjustment Range — Gain adjustable from -18 to +42 dB in 1 dB steps, compatible with both mic-level and line-level inputs on DSPs, mixers, and amplifiers.
• 120 dB Dynamic Range (XLR) / 130 dB (Dante/AES3) — Transparent digital audio with ample headroom for high-SPL sources without audible compression or clipping artifacts.
• Four-Port Network Switch Built In — Operates in Switched mode (all four ports carry Dante and Shure control) or Split/Redundant mode (separate Dante and control networks) for flexible AV network design.
• Wireless Workbench and Control System Integration — Full support for Shure Wireless Workbench software and mobile app; compatible with AMX, Crestron, and third-party control systems via network commands.
• TAA Compliant — Meets Trade Agreements Act requirements for U.S. federal government procurement, including GSA schedule purchases, without waivers.

Typical Applications

• Government space — TAA compliance and AES-256 encryption support wireless audio in federal courtrooms, legislative chambers, and secured government conference facilities.
• Broadcast studio — 130 dB digital dynamic range and sub-3 ms latency support live production, news studio, and broadcast AV applications.
• Auditorium — HD mode supports large-scale wireless deployments in performing arts centers, lecture halls, and multi-use auditoriums.
• Boardroom — Dante integration and network control allow wireless microphone management in enterprise boardrooms and executive conference suites.
• House of worship — Wide tuning range and interference management support reliable wireless audio in large worship venues with complex RF environments.
• Commercial meeting space — Scalable channel deployment fits multi-room wireless systems in hotels, convention centers, and corporate campuses.

Frequently Asked Questions

What transmitters are compatible with the AD4DNPTA=-A?

This receiver is compatible with all Shure AD series and ADX series transmitters in Band A, including handheld (AD2), bodypack (AD1), boundary, gooseneck, and instrument transmitters. Transmitter and receiver must be matched to the same frequency band.

Why does the AD4DNPTA ship without a power supply?

The NP (No Package) configuration is intended for integrators adding receivers to an existing Axient Digital rack. Multiple AD4D and AD4Q receivers can share power through the locking AC cascade connector using standard IEC extension cables, eliminating the need for individual power supplies in multi-receiver configurations.

Does this receiver work on existing Dante networks?

Yes. The AD4D includes a 4-port network interface supporting Dante primary and secondary streams. It can operate in Switched mode (all four ports carry Dante and Shure control) or Split/Redundant mode (dedicated Dante and control networks) to match existing network architecture.

What does TAA compliance mean for procurement?

The TAA-compliant designation confirms that the product was manufactured or substantially transformed in a country covered by a U.S. Trade Agreement. This is required for products purchased under GSA schedules and most federal agency IT and AV contracts without requesting a waiver.

When should I use High Density mode versus Standard mode?

High Density mode is suited for high-channel-count deployments where transmitters operate within 6 to 60 meters of receivers — conference centers, legislative facilities, or corporate campuses with many simultaneous channels. Standard mode is preferred when fewer channels are needed or transmitters must operate at longer range or higher RF power.

Can gain and mute be controlled remotely?

Yes. Gain, mute, frequency, and RF power can all be controlled remotely via Shure Wireless Workbench software, the Wireless Workbench Mobile app, or AMX/Crestron commands over the network — no front-panel access required during live operation.

What is the warranty on the AD4DNPTA=-A?

Shure provides a two-year manufacturer warranty on the AD4D receiver. Purchasing through Creation Networks, an authorized Shure reseller, ensures full warranty coverage. Contact Creation Networks for support or warranty service.
