Excellent!! Got what I need and very fast!! Thank You
;
Manual acquired with good resolution, complete in all its pages, very good policy of the folder where are saved all products purchased.
;
Service manual very complete and clear. It was very helpfull for my work.
;
This is the 2nd time I download manuals from this website and I can say it's what I was expecting. It contains schematic, layout (decent quality), short description, parts and dissasembly instructions. I recomend it for anyone who wants to repair/modify this device.

7.1.6 OUTLINE OF THE WAVEFORMS RECEIVED BY THE DSP SECTION
A
The illustrated signal waveform is an example of the signal waveform when a Dolby Digital (Fs = 48 kHz) signal is received. It must be noted that a frequency (waveform period) other than that of the Master clock supplied to the DSP section changes depending on the format of input signals or mode of the unit. It must also be noted that the waveform being observed changes depending on the environment of the measurement system (high-frequency characteristics of an oscilloscope or a probe, grounding method, etc.). (The numbers 1-9 of the waveform names correspond to those of the waveform data and those in the clock flowchart.)
S/PDIF signal waveforms
� Flow indicated with " " in the clock flowchart Aperiodic rectangular-wave signal 1 COAXIAL or demodulator input: Amplitude of approx. 5 Vp-p (when the signal is input to IC101) 2 OPTICAL input: Amplitude of approx. 4 Vp-p (when the signal is input to IC101) 3 OPTICAL output: Amplitude of approx. 3.3 Vp-p (when the signal is output from IC101) In the following waveforms, the amplitude of all clocks is approx. 3.3 Vp-p.
