When Dolby decoder module is fitted it provides ten possible sources The first eight are the standard signals which Dolby E can carry Signals nine and 10 are a stereo down mix created using whatever down mix coefficients have been set in the incoming Dolby E data stream Meter The next folder is called METER and manages the sources to the audio bargraph displays The meter can display up to 16 bargraphs Changing the source to a bargraph which is already displayed will cause the function to change immediately Adding extra bargraphs by changing the source from OFF to on by selecting a source Bargraphs are removed by setting them to OFF will result in a display that changes once the system manager has been closed Analogue and Digital outputs When fitted these output modules each have 8 audio legs In the case of the AES digital ones they are often assigned in pairs but unrelated audio can be placed on the left and right parts of the stereo pair if required Dolby decoder The Dolby decoder has no external input port so the input is seen as a destination to which one of the physical input ports must be routed Dolby data is encoded onto a similar data stream as that used for a stereo AES audio signal Clearly the data cannot come via an analogue port so they do not appear in the source list for the Dolby module Any of the AES input ports or SDI decoded signal pairs can be used as the source for the Dolby module 7 12 Audio synchro

A simple version of the 0760 has no AES or analogue audio inputs and only one SDI input That SDI input can be either HD or SD and the meter will auto switch between the two modes It can display waveforms for the luminance Cb and Cr colour difference signals and RGB converted versions of the incoming signal as well as having a vectorscope It can also perform time shift measurements with the use of the analogue reference input Analogue and digital AES audio inputs and outputs and extracting audio from Dolby encoded signals are all extra cost options 0760 meters with audio capabilities those with model numbers not ending in V can display on bargraphs all of the 16 audio signals mono that could be embedded into an SDI signal The simple stereo audio phase indicator with both a bargraph and a goniometer audio phase scope is supplemented by the full StarFish JellyFish display first launched on the MSD ranges of audio meter The power and utility modules are always required as is at least one module for SDI input s The analogue reference input and an SDI output are also normally fitted as standard which leaves space for five additional modules which can include up to 1 Dolby module 2 AES input modules 2 analogue input modules 2 AES output modules 2 analogue output modules The DVI output port is of the DVI I type carrying not only the digital signal but also an analogue one that via a suitable adapter cabl
