Notice that 3 years long, there was no top end amplifier in

10、 the lineup. This year, after 4 years development, the SC-LX90 is the new flagship. By the product names you can recognize basic features as there is a certain naming convention: A Advanced 9ch MCACC available i i-link input available V HDMI input (optional conversion from analalogue input to analog

11、ue output). H Conversion from analogue input to digital output available. S Conversion from analogue input to analogue/digital output with resolution up scaling available. Model suffixes are not applicable to LX models (i.e. VSX-LX50, SC-LX71, ). 1.2 Product specifications 1.2.1 Digital Video Conver

12、ter (DVC) Some AV amplifiers have the possibility to convert input signals to another type of output signal. This way, it can be possible, for example, to connect a DVD player to component, a game console to composite and only use the composite output to view either DVD or game console. This makes a

13、 large setup easier to connect. This conversion is done internally by the DVC (Digital Video Converter) and the capabilities are depending on the AV amplifier model. These are the different types of Digital Video conversion available: Pioneer amplifiers cant convert HDMI input to an analogue output:

14、 Main reason is that analogue outputs cant carry HDCP copy protection. So converting HDMI to analogue would mean removing HDCP. This is not allowed and therefore Pioneer amplifiers cant do this conversion. SC-LX90 practical repair guide 4 1.2.2 Return to factory settings When audio and video setting

SC-LX90 practical repair guide 8 1.3 Audio information 1.3.1 Audio coding formats When audio is digitally recorded on a medium, there are several digital coding formats that can be used. Overview of some audio coding formats: Audio carriers (CD, DAT, SACD, DVD-A, ) are typicall

42、y 2ch audio, with exception of SACD & DVD-A, and have the complete memory available for audio data. Compressing audio is not necessary and for these mediums PCM or DSD coding is mostly used. Video carriers (LD, DVD, BD) generally have multi channel audio and have to share the complete memory of the

43、medium for video data as well. In these cases its necessary to compress audio data to be able to get all the video data on there as well. These mediums usually have Dolby, DTS coding. Since the launch of blu-ray disc and HD-DVD, much more memory is available and compression is less necessary. These mediums can carry high definition audio in the form of Dolby trueHD, DTS- HD and PCM. Portable media have gained popularity ever since internet was accessible to most people.
