Shure Axient Digital Handheld Transmitter AD2/Beta 87A (Band H54 520-636MHz)

Premium Wireless Audio for Professional Vocals

The Shure Axient Digital Handheld Transmitter AD2/Beta 87A, operating on the H54 frequency band (520–636 MHz, subject to Australian regulations), features the renowned Beta® 87A condenser vocal microphone capsule, delivering impeccable 24-bit/48 kHz digital audio for vocalists and presenters across Australia. Compatible with Axient® Digital Wireless Systems (receiver sold separately, e.g., AD4D or AD4Q), this transmitter offers breakthrough RF performance, wide tuning range, and AES 256-bit encryption, making it ideal for high-profile live performances, broadcast, and mission-critical installations. Its rugged metal construction and advanced features ensure reliability in demanding environments.

Exceptional Vocal Clarity

The Beta 87A capsule features a supercardioid polar pattern, providing high gain-before-feedback and superior rejection of off-axis noise, ideal for loud stages or critical vocal applications. Its extended frequency response (20 Hz – 20 kHz, microphone-dependent) and 120.5 dB dynamic range deliver smooth, detailed vocals with a gentle presence rise for enhanced clarity. The condenser design captures subtle nuances, making it perfect for professional singing, presentations, and broadcast. The AD2 transmitter supports automatic gain adjustment, two transmission modes (Standard for optimal coverage, High Density for maximum channel count), and a wide 184 MHz tuning bandwidth for robust RF performance. A backlit LCD displays group/channel, frequency, or battery runtime, and the low-profile, lockable power switch prevents accidental changes.

Advanced Features and Durable Design

The AD2/Beta 87A leverages Shure’s cutting-edge Axient Digital technology, including digital diversity and High Density mode, supporting up to 47 channels per 6 MHz TV band for interference-free performance in congested RF environments. AES 256-bit encryption ensures secure transmission for sensitive applications. The transmitter features durable metal construction in a black finish, with external contacts for dockable charging using the SBC200 Dual Docking Charger. It offers over 11 hours of battery life with the optional Shure SB900B lithium-ion battery or 8 hours with two AA batteries (included) at 10 mW. The interchangeable capsule design supports other Shure capsules (e.g., SM58, KSM9, Beta 58A) for versatility. IR sync enables quick receiver pairing, and Wireless Workbench® software provides networked control. Users must match frequency bands with receivers (e.g., AD4D H54) for proper operation and verify local regulations for H54 band usage.
