Introduction
The BCS25 isspecificallydesigned forapplicationsrequiring afull-featured mixing consolewhilebeing
restricted bydimensionaland/orfinanciallimits. Post-production rooms, OBvans, on-location transmission
studiosand secondary studiosareonlyafewofthe possibleusesforthe BCS25.
The BCS25 frameissupplied with8input channels(optionalwithorwithout equalizer), the buildinpower
supplyand an extensivemastersection withLEDPPM's.
Inputmodules
The universalBCS25(E) input channelfeatures3inputs(line 1, line 2and mic), againcontrol, a3-band
equaliser(option: without)and abalancecontrol. The input signalcan be routed totwostereo mix-busses
withthe audition and programselect buttons. Thisenablesthe engineertoset up twodifferent output mixes
ortousethe consolefortwodifferent jobsrunning simultaneously.
The auxiliary 1ispre-faderand hasavolumecontrolon the module. The auxiliary 2bussendsthe signal
directlytothe mastersection, the signalmaybe selected preorpost fader.
The cue button enablespre-fade listening ofthe input source. Afader/button start featureisstandard(fader
orbutton function isset byan internaljumper). The 100 mm faderisnot inthe audiosignalpathbut only
controlsthe VCA; thispreventsanysignaldistortion and increasesreliability.
Telephonehybrid
Thereisalsoaspecialtelephone channelavailablewithintegrated analogue telephone hybrid. Thischannel
can alsobe used asaremoteforan externalhybrid. The ON/OFF buttonscan be used forthe remote
controlforthe externalhybrid.
The BCS26(E) isequipped withan intelligent electroniccircuit togenerateamix-minussignal(Dateq’s
unique TDM2). Thismakesit possibletohavemorethan one hybridinthe mixer.
BCS27 Master module
The mastersection isextremelywell equipped. It hasa40-segment LEDVU-meterwithpeakholdfunction
that can be linked toPGMout oreachofthe othersources. Inaddition the BCS27 hasamasterfaderfor
PGMout, an adjustableheadphone output formonitoring anysignal, levelcontrolsforotheroutputssuchas
aux, audition, etc.
Anysignalcan be selected tothe monitoroutputs(controlroomorheadphone)bymeansofthe switching
matrix.
The dedicated guest and the presenteroutputshaveavery practicalfeature. The engineerisabletosend a
different signalmix-than the actualPGM-toeachofthosetwooutputs. Thisenableshim/hertoperform
simpletimesaving 'post-production-during-transmission'type ofoperations!
Communication between engineer, guest and presenteriscompletelyhandled bythe console, offering
numerouspossibilities. The most interesting one isthe abilitytorout the communication signaltothe PGM
output. Thisoption hasbeen specificallyimplemented forliveon-location (OB) transmissions: it presentsa
direct and easycommunication channelwiththe studioengineerwhilenewsand commercialsarebroadcast
fromthe homebasestudio!
