Shure AD4DNPTA=-C Axient Digital Two-Channel Wireless Receiver with No Accessories (C: 750 to 960 MHz) (TAA-Compliant)

Product Overview

The Shure AD4DNPTA=-C 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 enterprise conference environments. Operating in Band C (750–960 MHz), this 1U rack-mount receiver integrates natively with Dante-enabled audio networks and supports AES3 and AES67 digital outputs. The -NP designation indicates it ships without a power supply or mounting accessories — the correct choice when deploying alongside existing Axient Digital receivers where AC power is already distributed via locking cascade connections in the rack.

Product Description

The AD4D supports two independent wireless audio channels in a single 1U rack space. Band C covers 750–960 MHz, providing a wide tuning range for frequency coordination in complex RF 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 — suitable for multi-channel wireless deployments across legislative facilities, convention centers, and large enterprise campuses. AES-256 encryption secures all wireless audio channels to meet security requirements for federal government and secure commercial spaces. The receiver is compatible with all Shure AD and ADX series transmitters, allowing integrators to combine handheld, bodypack, boundary, and gooseneck form factors within the same system. For installations requiring four channels in 1U on the same band, see the Shure AD4Q-DCTA=-C 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 installations.
• Band C: 750–960 MHz Tuning Range — Wide spectrum coverage in Band C for frequency coordination in multi-channel deployments in RF-congested 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 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 or Split/Redundant mode for flexible integration into existing AV network architectures.
• Wireless Workbench and Control System Integration — Compatible with Shure Wireless Workbench software and mobile app; supports AMX, Crestron, and third-party control systems.
• TAA Compliant — Meets Trade Agreements Act requirements for U.S. federal government procurement under GSA schedules and agency contracts.

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=-C?

This receiver works with all Shure AD series and ADX series transmitters in Band C (750–960 MHz), including handheld, bodypack, boundary, gooseneck, and instrument transmitters. Transmitter and receiver must be matched to Band C.

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, 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 operates in Switched mode or Split/Redundant mode to match existing network architecture.

What does TAA compliance mean for procurement?

TAA compliance confirms 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 AV contracts.

When should I use High Density mode versus Standard mode?

High Density mode suits high-channel-count deployments where transmitters operate within 6 to 60 meters of receivers. 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.

What is the warranty on this receiver?

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