Product Description

 Gonsin Infrared Interpretation System

Infrared Wireless Interpretation System


offers language distribution in 4/6/8/12 channels, easy setup, operate and maintain.

Our equipment has been widely used in many international projects, including governments, parliaments, education institutes, churches, hotels, conferences etc., and win very good comments from customers worldwide, due to its good sound quality, stable performances and good signal coverage.


IR Transmitter   

(2) IR transmitter

The TC-Z902V/Z904V/Z906V infrared transmitter is a microprocessor based central unit which is designed to modulate and transmit 2/4/6 sound channels to different carrier frequencies.  It features built-in IR test diodes for audio monitoring and testing of receivers, independent channel volume control, independent channel output level indicators, and independent channel audio output for sound recording.  Test mode produces a different frequency tone for each input/channel. Two BNC sockets can link up infrared radiators in two lines. Multiple interpreter consoles can be connected to the transmitter in a daisy chain.   

  • Modulation mode: FM
  • Frequency synthesis: digital PLL
  • Frequency band: 2.0 - 6.0MHz
  • Frequency response: 100-14kHz
  • Frequency stability: 10ppm
  • Pre-emphasis: 75 μSec.
  • Peak deviation: ±7.5kHz
  • Distortion at 1 kHz: <0.5%
  • Channel separation: >70dB
  • RF output power level: 700mV
  • RF output impedance: 55-75 ohms
  • Input impedance: 18k ohms
  • Max. input power level: 7.5V
  • AGC range: 30dB
  • S/N ratio: >75dB
  • Power consumption: 40W
  • Powe requirement: 110/240VAC, 50-60Hz
  • 19"rack mountable case
  • Dimension: 430×99×325 mm (W×H×D)



IR Radiator                    

(3) IR radiator


The TC-H15 high-power infrared radiator can be switchable to 50% low power, making it suitable for use in larger halls and smaller rooms. The radiators integrated power supply unit is automatically switched on and off by the carrier signals from the transmitter by means of an high frequency sensor. The radiator is equipped with automatic gain control to ensure the infrared diodes function with maximum efficiency, and is naturally convection cooled for totally silent and maintenance-free continuous operation. It can be ceiling or wall mounted for permanent installation, or set up on an optional tripod for portable application.Multiple radiators can easily be daisy-chained together to expand coverage. The unit is easy to maintain and clean, with IR emitting diodes protected by the cover plate.

  • RF input voltage: 100-2000mV
  • Power consumption: 55W, Stand-by 8W
  • Power Supply: 110/240VAC, 50-60Hz
  • Operating temperature: 0-40
  • Cable: 75Ω-4 coax, BNC connectors
  • Dimensions: 450×211×82 mm




IR receiver (C)

The portable TC-J902L/J904L/J906L infrared receiver is designed to receive 2/4/6 audio channels.  The unit is powered by a more environment-friendly rechargeable Lithium-ion battery pack.  The selected channel number and battery level can be displayed on LCD screen.  The user may listen to any selected language on a personal earphone.  Volume level can be adjusted through a thumbwheel switch for comfortable listening.  Any number of receivers can be used within the radiator's effective coverage range. 

  • Slide switch for power on/off
  • Thumbwheel switch for volume control
  • 3.5mm phone output jack
