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