(In the case of multi-ch source) AC3D2av outputs dts or DOLBY DIGITAL encoded input signals from Lt/Rt (SDA21) without decoding. AC3Dav processes Lt/Rt output signals of AC3D2av by dts or DOLBY DIGITAL decoding and outputs them to LS/RS (SDA10) and RC (SDA12, L only) through 3/0 down-mixing. DSP6#1 outputs the LS/RS input signals to RLdr/RRdr (SD612) and the RC (L only) input signals to RC (SD615, L only).

The input data is automatically identified and switched in the priority order of dts > DOLBY DIGITAL > PCM AUDIO > Analog (A/D) according to the signal detection. The main L/R uses the analog through method when analog signals are input and the DSP through method when digital signals are input. There are two sub-menu items (2ch/MULTI, FULL BIT).

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.) As for internal/external synchronization switching of super-imposing (image signals), forced external synchronization is selected by the microprocessor control.

All segments ON (dimmer 50%) [Remote control code: ]
Segment conditions of the FL driver (IC901, IC902) and the FL tube are checked by turning ON and OFF all segments. Next, the operation of the FL driver is checked by using the dimmer control. Then a short between segments next to each other is checked by turning ON and OFF all segments alternately (in a lattice). (In the above example, the center segment in the second row from the top is shorted.)

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

ALL [Remote control code: 7A00 (TAPE PLAY)] Noise is output through all channels. MAIN L [Remote control code: 7A01 (TAPE RW) Noise is output through the MAIN L channel. CENTER [Remote control code: 7A02 (TAPE FW)] Noise is output through the CENTER channel. MAIN R [Remote control code: 7A03 (TAPE STOP)] Noise is output through the MAIN R channel. REAR R [Remote control code: 7A04 (TAPE PAUSE)] Noise is output through the REAR R channel. REAR C [Remote control code: 7A05 (TAPE MUTE)] Noise is output through the REAR CENTER channel. REAR L [Remote control code: 7A06 (TAPE A/B)] Noise is output through the REAR L channel. FRONT L [Remote control code: 7A07 (TAPE DIR A)] Noise is output through the FRONT L channel. FRONT R [Remote control code: 7A08 (CD PLAY)] Noise is output through the FRONT R channel. LFE [Remote control code: 7A09 (CD STOP)] Noise is output through the LFE (sub-woofer) channel.

9. RS-232C

This menu is used to check transmission of the data and the flow port of the hardware. With the power turned off, short between pins No.2 (RxD) and No.3 (TxD) and between pins No.7 (RTS) and No.8 (CTS) of the RS-232C terminal. (Be sure to turn off the power when shorting pins.) Start DIAG and select the menu. There are two sub-menu items. 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.)

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.

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. 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.
