IMPORTANT NOTICE

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.
The presentation or sale of this manual to any individual or firm does not constitute authorization, certification
or recognition of any applicable technical capabilities, or establish a principle-agent relationship of any
form.
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).
Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the
unit.

  • Page 10: Self Diagnosis Function

    DSP-AX1/RX-V1 SELF DIAGNOSIS FUNCTION This product has a built-in self diagnosis function (DIAG) to facilitate inspection, measurement and determination of a faulty item, if any. There are 14 DIAG menu items each of which has sub-menu items. Listed in the table below are menu items and sub-menu items.

  • Page 15 DSP-AX1/RX-V1 Details of DIAG menu In each menu, “SPEAKERS” is always set to “LARGE”, D-RANGE to “MAX”, LFE LEVEL to 0dB (-10dB when DOLBY DIGITAL is used) and CENTER DELAY to 0ms unless otherwise specified. 1. DSP THROUGH There are 3 sub menu items (ANALOG BYPS, DSP 0dB, FULL BIT).
  • Page 16 DSP-AX1/RX-V1 DSP 0dB [Remote control code: 7A—91 (PRG 10)] The input signal is automatically identified and switched in the priority order of dts > DOLBY DIGITAL > PCM AUDIO > Analog (A/D) according to the signal detection. The L/R, C/LFE, FL/FR, RL/RR, RC signals are output through DSP.
  • Page 17 DSP-AX1/RX-V1 2. DECODER THR. The input signal is automatically identified and switched in the priority order of dts > DOLBY DIGITAL > PCM AUDIO > Analog (A/D). There are two sub-menu items (YSS918/908, FULL BIT). This menu is used to check the signal passage of the decoder LSI (YSS918, YSS908).
  • Page 18 DSP-AX1/RX-V1 FULL BIT [Remote control code: 7A—10 (TUNER PRESET +)] The head margin is unused and the digital data is output in full bit. The same applies as YSS918/908 except that the digital data is output in full bit at D/A.
  • Page 19 DSP-AX1/RX-V1 (In the case of multi-ch source) • AC3D2av outputs signals using DOLBY DIGITAL/dts decode operation. • DSP6#1 outputs the L/R signals to L/R (SD610), RC (SD615, L only), C/LFE to C/LFE (SD611), LSt/ RSt to RLdr/RRdr (SD612). Also, it outputs L/2 + R/2 to FL/FR (SD614) through the external RAM.
  • Page 20 DSP-AX1/RX-V1 4. PRO LOGIC The input data is automatically identified in the priority order of PCM > Analog. DTS is inhibited. There are three sub-menu items. Either Pro-logic (auto input balance turned off ) or EFFECT OFF (analog through) is selected.
  • Page 21 DSP-AX1/RX-V1 YSS908 [Remote control code: 7A—9D (SET UP)] When the analog, PCM audio or DOLBY DIGITAL 2/0 mode is used, LS, RS, RC signals are pro-logic decoded in YSS908 and output. When the DOLBY DIGITAL mode other than 2/0 is used, the pro logic function does not work and they are muted.
  • Page 22 DSP-AX1/RX-V1 5. BYPASS Only PCM and analog modes are used for input signals. The bypassing operation is used according to the menu setting. There are two sub-menu items (DECODER, DSP). This menu is useful when locat- ing the faulty part by bypassing the decoder LSI and DSP6.
  • Page 23 DSP-AX1/RX-V1 6. SPEAKERS SET The input signal is automatically identified in the priority order of dts > DOLBY DIGITAL > PCM > Analog. There are seven sub-menu items. The signals output from the DSP are the same as 1. DSP THROUGH: DSP 0dB.
  • Page 24 DSP-AX1/RX-V1 7. DISPLAY CHK This program is used to check lighting of the FL display which changes as shown below according to operation of the sub-menu. The signals are processed in the same way as EFFECT OFF of No.4. (The L/R signal is output using ANALOG MAIN BYPASS setting.)
  • Page 25 DSP-AX1/RX-V1 8. MANUAL TEST The test noise is output by the noise generator with a built-in DSP through the channels specified by the sub-menu. There are ten sub-menu items. 8. MANUAL TEST ALL [Remote control code: 7A—00 (TAPE PLAY)] Noise is output through all channels.
  • Page 26 DSP-AX1/RX-V1 10. PRESET This menu reserves and inhibits initialization of the back-up RAM (parameter, set menu contents, etc. for the sound field program). The input signals are automatically identified in the priority order of AC-3 > PCM > Analog. The signals are processed in the same way as EFFECT OFF of No.4.
  • Page 27 DSP-AX1/RX-V1 11. FAN/AD The sub-menu of this menu displays the A/D conversion value of the main CPU (function circuit board IC27) which detects the keys and protection functions of the main unit in %. (100% represents 5V.) It also displays the history of the fan being driven. When in KY0/KY1 page, it is not possible to operate the keys of the main unit because the values of all keys are detected.
  • Page 28 DSP-AX1/RX-V1 12. IF STATUS Using this menu, the status data is displayed in the hexadecimal notation one after another. During signal processing, the status before execution of this menu is maintained. If the input mode is analog fixed in the menu before execution, it is necessary to change it to the digital mode according to the following procedure.

  • Page 30 DSP-AX1/RX-V1 13. DSP RAM CHECK This menu is used to self-diagnose whether or not the external RAM (IC33, 34, 35) and DSP (IC7, 8) are connected properly, utilizing the CPU -Ext. RAM interface function included in DSP6. During signal processing, the status before execution of this menu is maintained.
