IMPORTANT NOTICE
This manual has been provided for the use of authorized YAMAHA Retailers and their service personnel. It has been assumed that basic service procedures inherent to the industry, and more specifically YAMAHA Products, are already known and understood by the users, and have therefore not been restated.
WARNING:
Failure to follow appropriate service and safety procedures when servicing this product may result in personal injury, destruction of expensive components, and failure of the product to perform as specified. For these reasons, we advise all YAMAHA product owners that any service required should be performed by an authorized YAMAHA Retailer or the appointed service representative. technical capabilities, or establish a principle-agent relationship of any form.
IMPORTANT: The presentation or sale of this manual to any individual or firm does not constitute authorization, certification or recognition of any applicable
AV-S70/NX-SW70
The data provided is believed to be accurate and applicable to the unit(s) indicated on the cover. The research, engineering, and service departments of YAMAHA are continually striving to improve YAMAHA products. Modifications are, therefore, inevitable and specifications are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, please contact the distributor's Service Division.
WARNING:
Static discharges can destroy expensive components. Discharge any static electricity your body may have accumulated by grounding yourself to the ground buss in the unit (heavy gauge black wires connect to this buss). IMPORTANT: Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the unit.

s DSP DIAG MODE (Self-diagnosis)
Use the remote controller supplied as an accessory to select the menu. 1. Procedure for starting DSP DIAG Referring to TEST PROGRAM MODE in the previous section, select/execute "04 DSP Diag". When "04 DSP Diag" is executed, the current input name appears on the display followed by "Video" > "Sel.1to9 Key". (The DSP indicator keeps flashing.) 2. Procedure for selecting Main menu and Sub-menu Using [1] through [9] keys on the remote controller, select the main menu. Soon the sub-menu will appear on the display. Then, select the sub-menu. Every time the selected key (on the remote controller) is pressed, the sub-menu on the display changes.

1. Analog Thr.
The input is fixed to use the analog (A/D) and has 2 sub-menu items. MAIN BYPSS The main L/R signal is output through the analog bypass without passing the DSP section. The main L/R signal passing through the DSP is output through C/LFE and RL/RR.

2. DSP Through
In the DIGITAL input mode, AC3/PCM AUDIO signal is automatically identified. There are 3 sub-menu 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.

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.

The sub-menu items include selection of Pro-logic (The auto input balance is off.) and EFFECT OFF.
CENTER LARGE 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.

SYSTEM CONNECTOR (Pin 90 of IC701)
1. Pin 3 of the system connector (CN602) detects if the subwoofer is equipped / not equipped / faulty.

4 1 6 2 8 7 5 3
· When the system connector is connected correctly and the subwoofer is operating properly, approximately 4 to 5V voltage is obtained. · When the system connector is not connected, approximately 2.5V voltage is obtained. · When the protection circuit of the subwoofer is at work, approximately 0 to 2V voltage is obtained and the protection circuit of AV-S70 works together with it.
2. When the system connector is not connected or the power of the subwoofer (NX-SW70) is not turned ON, only VIRTUAL SURROUND and MONO MOVIE functions of the sound field program are available.
