Bosch Integrus: The Industry Standard for Digital Infrared Simultaneous Interpretation

As the global Gold Standard in conference interpretation, the Bosch Integrus system offers unparalleled stability and professional-grade performance.

It effectively overcomes the limitations of traditional analog systems, ensuring total immunity to interference from high-intensity ambient lighting and electronic ballast.

Core System Components

1. Bosch INT-TX4 Digital Infrared Transmitter

   
   

   Serving as the "Brain" of the system, the INT-TX4 converts analog audio from interpreter consoles into high-fidelity digital signals. It supports up to 4 language channels (expandable to 32 with the TX32 model), delivering lossless, studio-quality audio.

   
   

2. Bosch LBB4512 High-Power Radiators

   
   

   The "Signal Beacons" of the setup, these radiators convert electrical signals into infrared light. Featuring automatic gain control, their strategic installation—optimized for height and coverage angles—eliminates signal dead zones in complex venue layouts.

   
   

3. Bosch DCN-CCU Central Control Unit

   
   

   The "Heart" of the system, the DCN-CCU manages the synchronization between interpreter desks and transmitters. Its high-speed digital processing ensures near-zero latency (< 2ms), a critical factor for real-time simultaneous translation.

   
   

4. Bosch LBB4540 Digital Infrared Receiver (Pocket Receiver)

   
   

   Engineered with Bosch’s patented digital compensation technology, these are more than just receivers. They automatically correct signal disturbances caused by attendee movement or direct sunlight, maintaining a noise-free, pristine audio feed.

   
   

5. Bosch DCN-IDESK Interpreter Desk

   
   

   The only console fully compliant with ISO 2603 standards. It features silent-touch controls to prevent mechanical noise and supports Relay Interpreting, essential for multi-language international summits.

Why Bosch Integrus Remains Irreplaceable

1. Superiority of Infrared over 2.4G/UHF

In the saturated RF environment of 2026, infrared (IR) technology provides a secure, interference-free alternative. Because IR signals do not penetrate walls, they are physically protected from external interception. Unlike UHF or 2.4G systems that struggle with Wi-Fi 7 congestion, IR operates on the light spectrum, ensuring a dedicated, stable signal.

2. Advanced Digital Compensation

In large-scale venues, IR light often bounces off glass and reflective surfaces. Bosch’s digital technology performs "Signal Re-alignment," synthesizing reflected waves to ensure that attendees—even those seated in corners or near glass curtain walls—receive perfectly clear audio.

3. ISO 2603: Professional Hearing Protection

The DCN-IDESK allows two interpreters to independently adjust their volume and frequency response. A built-in Limiter automatically suppresses sudden acoustic peaks from the floor microphone, safeguarding the hearing of both the interpreters and the delegates.
