1. 2 B MCR42 main block diagram One of the milestones in the design of the MCR42 is high reliability most of the circuitry of the receiver is independent one from each other Above a schematic with an overview of main receiv er functions For each antenna the RF signal is split in the receiver 1 and in the receiver 2 antenna A and antenna B with a wide band splitter In this way any one receiv er could be tuned in any frequency of the switching range typ 240 MHz Receiver 1 and 2 are diversity receivers each one is made of two receivers tuned on the same frequency hereafter called section A and section B The re ceiver 1 section A and the receiver 2 section A are connected to the antenna A the receiver 1 section B and the receiver 2 section B are connected at the antenna B Each receiver has its own demodulated signal and its own RSSI signal Receiver Signal Strength Indi cation a DSP selects or combines signals from section A amp B to have the best audio The demodulated signal flows to the digital audio processor Receiver supervisor microcontroller and user interface Line 1 Line 2 Digital AES3 Output Digital Analogue output output audio 5 processor nn Ear ph Left Ear ph Right Ear phone INFRARED interface SERIAL LINK Data signalling detection and demodulation the data sub carrier is digitally fil2. of the manual It is needed to have proper replacement parts or accessories from the manu facturer When replacement parts are needed use only replacement parts authorized from the manufac turer Substitution with not authorized parts could result in electric shock hazards or fire Keep attention on all the labels with warnings or hazards on the apparatus WARNING The apparatus is intended for professional use anyway the manufacturer alerts the user that the headphone output power of the ap paratus could exceed the level of 85 dB A of sound pressure level and this could be dangerous for the hearings Do not use the headphone with high power level or for long time Reduce the power or suspend the hearing in case of any kind of hearing problem WARNING when operating thru battery pack always replace ALL BATTERIES DO NOT operate the device with some new and some old batteries When MCR42 is setup to automatically turn on DO CHANGE ALL OF USED BATTERIES after automatic low batteries shutdown Pag 4 MCR42 dual true diversity receiver Main features MCR41 42 is a camera dual true diversity wire less microphone receiver system in a modular stand alone or slot in configuration compatible with most camera s slot e Extreme RF radiofrequency performances and reliability e Extreme frequency agility tuning windows up to 240 MHz with independet tunables filters 2 ch s MCR42 L 470 678 M
