● Starting DIAG

For DSP-AX1: Press the “POWER” (STANDBY/ON) key of the main unit while pressing the “SET MENU+” key and the “NEXT” key located in the sealing panel of the main unit, and DIAG will be activated.

For RX-V1: Press the “POWER” (STANDBY/ON) key of the main unit while pressing the “PROGRAM w” key and the “EFFECT” key located in the sealing panel of the main unit, and DIAG will be activated.

● Starting DIAG in the protection cancel mode

If the power supply, amplifier protection function is activated and hinders the trouble diagnosis, cancel the protection function as described below, and it will be possible to enter the DIAG mode. (The protection function other than the excess current detect function will be cancelled.)

For DSP-AX1: Press the “POWER” (STANDBY/ON) key while pressing the “SET MENU+” key and the “NEXT” key. At this time, keep pressing the “SET MENU+” key and the “NEXT” for 3 seconds or longer.

For RX-V1: Press the “POWER” (STANDBY/ON) key while pressing the “PROGRAM w” key and the “EFFECT” key. At this time, keep pressing the “PROGRAM w” key and the “EFFECT” key for 3 seconds or longer.

In this mode, “ V ” in the FL display of the main unit flashes.

CAUTION!

Using this product with the protection function cancelled may cause damage to itself. Use special care for this point when using this mode.

● Canceling DIAG

Turn off the power by pressing the “POWER” (STANDBY/ON) key of the main unit or the “STANDBY” key of the remote control unit.

DSP-AX1/RX-V1

CAUTION: When canceling this function, check that DIAG menu No.10 PRESET (memory initialization inhibited/ reserved) has been set. (To keep the user memory, be sure to select “INHIBIT” (initialization inhibited) from the No.10 PRESET menu before canceling the DIAG function.)

DSP-AX1/RX-V1

● Display at the start of DIAG

The diagnostic menu appears on the monitor screen. (It remains on display until it is canceled.)

On the FL display of the main unit, an opening message (including the version and the history of protection function) appears for a few seconds followed by the diagnostic menu display of 1 DSP THROUGH: ANALOG BYPS.

Opening message

When there is no history of protection function (*1)

NO PROTECT X/X M:XXXX / S:XXXX

Checksum of the main microprocessor

Checksum (4 figures consisting of alphabets and numbers) The checksum is obtained by adding 4M bits per 1 octo of the entire program code and expressing the result as a 4-figure hexadecimal data. (0xff is added for the area where no code has been entered and for the area other than ROM code.)

(*1) If the history of the protection function has been recorded, the type of the protection function and the voltage value recorded last are displayed.

In the case where the protection function works after DIAG has been started and the power is turned off ;

When the protection function (*2) works, the history of the protection function appears on display and the power turns off. Repair the faulty parts according to the displayed history.

(*2) When an excess current or any other faulty condition is found with the power source, DC, etc., the protection function forces the power to turn off.

I PROTECTION display

I PROTECT X/X M:XXXX / S:XXXX

PS PRT :000 X/X M:XXXX / S:XXXX

(When the power is turned on without an abnormality corrected, the protection function works the moment the power relay is turned on to shut off the power supply.)

Cause: There is an abnormal current flow to the power amplifier. Supplementary information: If I PROTECTION function has worked after

SP relay ON, a warning message “CHECK SP WIRES” appears the next time the power is turned on. This indicates that some trouble exists after the SP terminal, such as a short-circuit of the speaker cable.

PS PRT display

(When the power is turned on without an abnormality corrected, the protection function works about 1 second later to shut off the power supply. Display may not be provided, if there is an abnormality with the power supply for the display.)

Cause: There is an abnormality in the power supply section (voltage). Supplementary information: As the power from following sources is

detected, it is possible to determine where an abnormality exists.

Transformer secondary winding

VI X 2(CB704), YE x 2(CB482) U, C only : GY x 2(CB481)

Stabilizing power source

DC PRT display

DC PRT :000 X/X M:XXXX / S:XXXX

TMP PRT:000 X/X M:XXXX / S:XXXX

Besides the above possible causes, the cause may exist in the disconnected connector or around CPU. PS PRT, DC PRT and TMP PRT displays include the abnormal A/D value in % (voltage value obtained by considering 5V as 100%). Concerning this value, refer to DIAG menu No.11 FAN/AD described on page 28.

● History of protection function

When the protection function has worked, its history is stored in memory with a backup. Even when no abnormality is noted while the unit is being serviced, an abnormality which has occurred previously can be defined as long as the backup data has been stored. The protection history is cleared when DIAG is canceled by selecting “RESERVED” (memory initialization) from the setting items of the DIAG menu No.10 PRESET or when the backup data is erased.

(When the power is turned on without an abnormality corrected, the protection function works about 3 seconds later to shut off the power supply.) Cause: A DC output from the power amplifier is detected in the bad channel.

TMP PRT display

(When the power is turned on without an abnormality corrected, the protection function works about 3 seconds later to shut off the power supply.) Cause: The temperature of the heat sinks in the power amplifier is detected. When the temperature rises and an abnormality is detected, the power turns off.

DSP-AX1/RX-V1

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. But one click on the input selector of the main unit will cancel this function and sets to the next sub-menu. Clicking there more than once would change the input. If this has occurred, restore the input being tested. The signal processing state remains the same as that before executing this menu.

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.

1) Select either DIAG menu No.2 or No.3 and enter a digital signal.

2) Menu No.12 can be selected by pressing the INPUT MODE key of the main unit. (The input mode will be fixed to the digital mode.)

There are ten sub-menu items. The following status information is displayed in the hexadecimal notation according to the sub-menu operation.

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.

13.DSP RAM CHECK

#1:NoEr #2:NoEr

• Note that a bus error may be indicated also when there is an error with the terminal other than above buses.

• Detection for the bus check is executed immediately after resetting. An error which has occurred after starting DIAG cannot be detected.

#1, #2

Checks the address bus and the data bus of DSP#1 (IC7 of DSP circuit board) and DSP#2 (IC8 of DSP circuit board), and indicates the connection condition. “NoEr” appears when no error is detected.

When an error is detected in the data bus; 1619 (example): Indicates that there is an incorrect value between bits 16 and

19. If there are two or more incorrect values, priority is placed on the LSB side. When an error is detected in the address bus;

Ad01 (example): Indicates that the address bit 1 has an error. Ad17 (example): Indicates that the address bus bit 17 has an error. (With this product, however, it is possible that A8 and /OE are short-circuited.)

14. SUM/VER /PORT

There are four sub-menu items. Indicates the checksum, version, port of the main microprocessor (IC27 of the function circuit board) as well as the checksum and version of the sub-microprocessor (IC1 of the DSP circuit board). The signals are processed in the same way as EFFECT OFF under item 4. PRO LOGIC. (The L/R signals are output using ANALOG MAIN BYPASS.)

CAUTION : When replacing the microprocessor, be sure to check the microprocessor compatibility before replacement. The microprocessor may not be suitable for replacement depending on its communication format. Use of a microprocessor whose communication format is not compatible with the existing one will cause some communication error between microprocessors.

14.SUM/VER/PORT M:51F5 / S:A3BB

DSP-AX1/RX-V1

Checksum of main microprocessor (4 figures of alphabets and numbers)

Checksum of main/sub microprocessor

Checksum: The checksum is obtained by adding 4M bits per 1 octo of the entire program code and expressing the result as a 4-figure hexadecimal data. (0xff is added for the area where no code has been entered and for the area other than ROM code.)

Checksum of sub-microprocessor (4 figures of alphabets and numbers)
