1. JAD-INT64 & JAD-INT64-P | Professional Interpreter Desks
The JAD-INT64 is a high-performance interpreter workstation designed for the rigors of simultaneous interpretation. It features a high-fidelity internal processor and a sleek interface with a dedicated OLED display that shows incoming and outgoing channel data.
- The Pro Version (JAD-INT64-P): Includes an integrated IC-Card reader for professional identification and session tracking. It supports “Relay Interpretation,” allowing interpreters to listen to another booth’s output when they don’t understand the floor language directly. Both models feature a “Cough” mute button, slow-speech request signal, and dual-headset support for seamless handover between two interpreters in a single booth.


2. JAD-VLI700A | Infrared Transmitter (The Hub)
The JAD-VLI700A is the core of the distribution system. It encodes the audio signals from the Interpreter Desks and modulates them onto digital infrared carriers. Compliant with international standards (IEC 61603-7), it ensures that audio quality remains uncompressed and free from interference by high-frequency lighting or mobile signals. The unit features an intuitive LCD configuration menu and can manage up to 64 channels simultaneously, broadcasting them to the radiator units across the hall.

3. JAD-VLI701A & JAD-VLI701B | Digital Infrared Radiators
These high-output radiators are the “antennas” of the IR system. They receive the modulated signal from the transmitter and flood the room with invisible infrared light.
- JAD-VLI701A: The standard professional radiator, ideal for medium to large conference rooms.
- JAD-VLI701B: The High-Power variant designed for massive auditoriums or halls with very high ceilings. It features a wider coverage angle and greater signal throw, reducing the total number of units required for a single installation. Both models feature automatic power-on/off syncing with the transmitter and can be daisy-chained for easy cabling.




4. JAD-VLI703A Series | Digital Infrared Receivers
The JAD-VLI703A is the portable unit carried by every delegate. Ergonomically designed to be lightweight and pocket-sized, it features a clear LCD screen displaying the channel number and volume level. Using advanced digital synchronization technology, it instantly locks onto the IR signal from the radiators. The series includes variations for different channel counts (4, 8, 16, 32, or 64 channels), ensuring that delegates hear the interpretation with theater-quality clarity.


5. JAD-TC50A | Charging & Storage Case
Managing a large-scale event requires efficient logistics. The JAD-TC50A is a heavy-duty storage case that simultaneously charges up to 50 Infrared Receivers. Built into a ruggedized “Flight Case” with wheels, it is designed for the high-intensity rental and staging market. The intelligent charging circuitry prevents battery memory effect and provides status LEDs for every unit. When the lid is closed, the case protects your investment from dust, moisture, and impact during transport.

6. JAD-BTH-D | Soundproof Interpreter Booth
To provide accurate interpretation, linguists require a quiet, distraction-free environment. The JAD-BTH-D is a modular, ISO-compliant soundproof booth. It features high-density acoustic panels, a silent ventilation system, and large anti-glare windows to ensure the interpreters have a clear line of sight to the speaker. The modular design allows for rapid assembly and disassembly without tools, making it perfect for temporary events in hotel ballrooms or convention centers.







7. JAD-HPD & JAD-HPI | Professional AV Headphones
- JAD-HPD (Delegate Headphone): A lightweight, durable headphone designed for long-term comfort. It features high-impedance drivers optimized for speech clarity rather than music, ensuring the delegate never misses a nuance of the translation.
- JAD-HPI (Interpreter Headphone): A premium, closed-back headset with an integrated high-sensitivity microphone. It is engineered for maximum isolation, preventing the interpreter’s own voice from leaking back into their ears while providing the wide frequency response needed to catch every detail of the floor audio.

Key Functional Highlights
- Total Security: Unlike FM or Wi-Fi systems, IR signals cannot pass through walls. This makes the JAD series the only choice for secure government and legal proceedings where eavesdropping must be physically impossible.
- Interference-Free: The system operates in the high-frequency 2MHz to 6MHz range, meaning it is completely immune to interference from sunlight, fluorescent ballasts, or mobile phone signals.
- Unlimited Expansion: Because the signal is broadcast via light, you can add an unlimited number of JAD-VLI703A Receivers to a room without putting any additional load on the transmitter or degrading audio quality.
- Ergonomic Design: Every component, from the JAD-BTH-D booth to the JAD-HPI headphones, is designed for the “marathon” sessions of professional interpreters, focusing on comfort and long-term use.
