1 STUDIO & OB-VAN RECEIVERS MRK 950 Modur Wreess-Mcrophone Recever System 19 1U modue, stckbe, wth du true dversty recevers Mn Fetures Extreme RF (rdofrequency) performnces nd rebty. Tunn wndows of 240 MHz wth tunbes fters (2 ch s ndependent): L 470 MHz to 670 MHz (TV ch 21/45) H 630 MHz to 870 MHz (TV ch 41/70) EX 470 MHz to 800 MHz (TV ch 21/62) wth ntern sptter Wsycom dt expnson bus (DEXB) for future uprde/enhncement thru smpe sot-n crd (pc-ke). DEXB cn host DSP (40bt dsp processn) uprde crds provdn: dt output (.e. AES3, Ethersound) mut-compndn comptbty future dt functonty enhncements.

MRK 950 s desned to be: - esy & quck to use thnks to utomtc setup functons (.e. frequences, squech), remote confurton uttes (USB/Ethernet), dspy wth ntutve context menu nvton. - extremey fexbe, n fct ech of the two recevers cn work n 240 MHz bndwdth, more thn one rck cn be connected toether thru smpe USB cbe to ct mut-chnne recever. Moreover the DSP nterfce ows the unts to work wth sever dt udo output (.e. AES/EBU, Ethersound, ), mut-compndn comptbtes nd other dt fetures. - best n css performnces, thnks to the test Wsycom technooy the unt hs extreme RF senstvty nd mmunty nd superb udo quty. - durbe & uprdbe nvestment, thnks to the very robust desn (umnum housn) nd the possbty of uprde/enhnce unts performnces wth smpe sot n crd (pc-ke thru the DEXB expnson bus) Moreover MRK 950 system s redy set up for the excusve PTT functon, recenty deveoped by Wsycom nd now pprected n the brodcst word. It s be to work drecty wth the new wreess mcrophones provded wth but-n teemetry (ether body-pck or hnd-hed trnsmtters) nd Push-To- Tk button: smpy pushn ths button, the presenter cuses the remote swtchn of the recever s output-ne, from the mn ne to the ddton ntercom ne, n order to be be to tk off-r drecty wth the technc tem (optony stuttern tone s bck enerted to sn the presenter of the push to tk sttus).
