The MSR 918-D receiver module is the result of the most advanced wireless-microphone technology, necessary when working in the DVB-T era. Besides the very high sensitivity and superb sharp selectivity, it presents also an outstanding freedom from intermodulation and interferences.
It allows the remote monitoring of the TX battery lifetime and it is endowed with the “digital sub-carrier tone-squelch”. These features are obtained by a special sub-carrier, digitally modulated in word, that is generated by the last-generation Wisycom transmitters in order to send out to the relevant receiver important working information, like the battery-status and the pushing on the PTT button. This telemetry technology operates without affecting the audio signal’s quality or bandwidth. The MSR 918-D receiver,if provided with the optional, built-in, ITC 918 interface, will give to the reporter the possibility to talk directly and “off air” to the technicians of its team. Every time the reporter pushes the (optional) PTT push-button of the MTH400 Handheld Transmitter the audio output line of the receiver is switched from the “main line” to the auxiliary “intercom line”. Correlated with this intercom output line activation, on the MSR 918-D Receiver is also available a GPI (General Purpose Interface) relais dry-contact output, suitable to be connected with other external equipments. The GPI contact becomes closed every time the reporter operates the PTT push-button. The MSR 918-D is endowed also with a 1 kHz calibrating tone-generator, that allows to test easily the audio line output and the mixer input.
