Deity Theos DIFB Kit - wireless IFB monitoring system

Deity Theos DIFB Kit - wireless IFB monitoring system

The Deity Theos DIFB Kit is a complete, professional-grade wireless monitoring system (IFB, Interruptible Foldback) that provides the crew, director, clients and producers with a real-time, crystal-clear connection to the recording studio’s mixer. This comprehensive system operates on the wideband digital UHF spectrum (550-960 MHz), ensuring an exceptionally reliable signal without interruptions – even in the most congested filming environments or large events.

The whole team on the same frequency: This ready-to-use kit includes three separate listening receivers and one powerful transmitter. It’s the perfect solution for commercial productions, corporate videos, and film crews looking to build a reliable, fast-deploying monitoring ecosystem for clients and backstage crews.

• Complete ready-made package: Includes 3x DIFB receivers, 1x DBTX bodypack transmitter, and the necessary cables and accessories.
• True Diversity security: Thanks to the receivers' two separate SMA antennas, the devices always lock onto the strongest signal, minimizing dropouts.
• Smart GPS frequency adjustment: Using Global OneBand™ technology and your smartphone's GPS connection, the system automatically adapts to the official frequency regulations of each country and region.
• Text-to-Speech: Since devices are often carried in a pocket or on a belt, the receiver can read the selected channel or transmitter name directly into the headphones. There is no need to dig out the device to check the channel.
• 20-channel memory bank and auto-pairing: The receivers can scan and store up to 20 different frequencies, which can be quickly switched between using the metal roller control.

Fast deployment and advanced remote management

The Deity Theos DIFB Kit is designed to make getting started on a shoot day easier. The devices feature a convenient auto-pairing feature that scans the environment and connects the receivers to the transmitter in the blink of an eye. System settings, frequency scans and channel libraries can be managed and bulk updated directly from your smartphone via the Sidus Audio app, saving significant time in multi-device systems.

All devices in the series are equipped with bright full-color LCD displays and packaged in sturdy, durable metal bodies that have been tested to withstand drops to hard ground (1 meter drop test).

Superior battery life for long shooting days

The system offers best-in-class power management. The receivers operate on two standard AA batteries or rechargeable batteries, and high-quality lithium batteries provide up to 15-17 hours of continuous operation (about 10 hours with standard alkaline batteries). This means that even the longest shooting days can be easily powered without interruption. In addition, the devices have USB-C ports for continuous external power supply.

The receivers feature standard, locking 3.5mm headphone jacks to prevent accidental disconnection of the cables. The devices also support Bluetooth connectivity, so in addition to traditional wired headphones, wireless Bluetooth headphones can also be used with them.
