Deity Microphones HUSH Wireless DIFB Transmitter

About: Deity Microphones HUSH Wireless DIFB Transmitter

The HUSH Wireless DIFB Transmitter (DIFB TX) is Deity’s professional digital IFB transmission platform engineered specifically for North American RF environments. Built on a new RF architecture featuring a 175 kHz RF bandwidth and 300 kHz channel spacing, the HUSH DIFB TX is designed for clean coordination, predictable performance, and real-world reliability in dense RF deployments. This professional spacing strategy prioritizes stability and margin, making HUSH ready for broadcast, live production, and mission-critical IFB workflows.

Housed in a compact metal chassis, the HUSH DIFB TX delivers consistent digital audio performance with selectable RF output power up to 100 mW, allowing operators to balance coverage and RF congestion as needed. Fine 100 kHz frequency tuning enables precise coordination, while the conservative 300 kHz spacing reduces adjacent-channel interaction and helps maintain clean operation across multi-transmitter setups.

The transmitter supports mic-level and line-level inputs with selectable bias voltages, making it flexible for IFB feeds from mixers, carts, or distribution systems. A high-resolution audio path with 24-bit ADC at 48 kHz preserves clarity for cueing and program monitoring, while robust RF performance ensures dependable delivery to talent, clients, and crew.

Designed to scale, the HUSH DIFB TX integrates with the Sidus Audio app for RF configuration and coordination, streamlining setup on complex productions. Its durable metal construction and wide operating temperature range make it suitable for demanding professional environments where uptime is critical.

With its coordination-first RF design and professional-grade spacing, the HUSH Wireless DIFB Transmitter is built for productions that require dependable IFB delivery without compromise.

HUSH Wireless is a new RF platform and is not compatible with THEOS transmitters or receivers.
