INFRACOM Simultaneous Interpretation System
MSI8D - Compact Transmitter
Description
The Compact Transmitter MSI8D is used within the INFRACOM conference system for the transmission of 8 audio channels by infrared light in Band II (55 kHz – 1.35 MHz). The audio signals are converted into frequency modulated infrared light and then transmitted with INFRACOM Radiators HLN82, which are directly connected to the MSI8D. The original (OR) and up to 7 further languages can simultaneously transmitted on different carrier frequencies by narrow band frequency modulation. The transmitted signals are received by the INFRACOM Receiver IRX and can then be monitored with headphones.
With miniature-switches on the front panel of the MSI8D the frequency band can be chosen and the channels can be switched ON or OFF. With a rotating switch it is possible to assign up to 32 transmission frequencies to the different channels. Several MSI8D may be cascaded.3 infrared transmitter diodes allow monitoring for the technician directly without radiators. Eight green LEDs (INT) indicate the status of the interpreter channel.
LED’s on the front panel are indicating the operation mode: channel ON (red) and audio signal available (green). For Band IV (2-6MHz) an own transmitter is available. The MSI8D complies with international standard IEC914, IEC61603-3 (standard operation) and IEC61603-7 (extended operation).
