■ AV-S70 DISASSEMBLY PROCEDURES (Remove parts in the order as numbered.)
1. Removal of Grille Assembly.
a. Push up the Grille Assembly with a flat tip screwdriver
or the like inserted from the bottom. (Fig. 1).
b. Keep pushing up the Grille Assembly gradually until it

items.
YSS908-SRAM
The main L/R signal is sent through AC3D2av into DSP. After passing through SRAM,
the main L/R signal is output through L+R and C/LFE and RL/RR signals through
(L+R)/2.

256K SRAM
The shaded square means that the element included in it does not operate.
DSP FULL BIT
The main L/R is input through AC3D2av to DSP and then output through all
channels. The head margin is eliminated and the digital data is output in digital full
bit. The same applies as “YSS908” except that the digital data is output in full bit
at D/A.

Full bit: The digital data is normally output with a head margin for each of C and RL/RR
channels. In this menu, no head margin is used and the digital data is output in full bit so as to
obtain the A/D and D/A characteristics fully. Note that this means the analog gain after D/A is
larger as compared to L/R. Also, the LFE channel also outputs the signal in full bit.
3. AC-3 Through
Only the signal of the digital system is input. The AC3 signal is decoded and reproduced according to
the input source.
The AC-3 signal in each channel is AC-3 decoded and output through AC3D2av.
The combined status information of the sampling frequency and the number of channels of the AC3 signal appears on the Fl display.

As signal identification is executed in normal AC-3 reproduction, the source (DAT, CD-ROM, etc) without digital
data bit of IEC958 cannot be reproduced even when it is AC-3 encoded. On the other hand, as this menu does not
execute such digital data bit identification, these sources can be AC-3 reproduced. (To measure characteristics
during AC-3 reproduction, use the AC-3 decoded sine wave.)
However, note that with the sources that have not been AC-3 encoded, a decode error occurs and muting is
applied. In addition, by displaying the combined status information of the sampling frequency and the number of
channels of the AC-3 signal on the FL display, malfunction of the decoder can be detected.

When the analog, PCM audio or AC-3 2/0 mode is used, L, R, C, S signals are prologic decoded and output. When the AC-3 mode other than 2/0 is used, the pro logic
function does not work and the signals are AC-3 reproduced.

This menu is for checking during the production process and not for servicing.
The input L/R signal is output through the specified channels according to the sub-menu.
There are 7 sub-menu items.
The signal output from the DSP section is normally in the EFFECT OFF state in the menus from 1 to
3. In the menus after that, the same signal as in the menu of 2. DSP THROUGH: YSS908 is output.
The analog switch settings in each sub-menu are as shown in the following table.
