4. CONTENTS OF DIAGNOSIS FUNCTION
This section describes the contents of the self diagnosis function in detail.
No.1 ANALOG THROUGH
The input is fixed to analog (A/D). There are two submenus.
1. MAIN BYPASS
The MAIN L/R signals bypass the analog circuits to be output.
For CENTER/SUBWOOFER, FRONT L/R and REAR L/R, the MAIN L/R signals via the DSP are output without
being processed (through). (Remote control code 7A-88)
: This shows that the device is not operating.
2. DSP 0dB
MAIN L/R, CENTER/SUBWOOFER/LFE, FRONT L/R and REAR L/R pass through the DSP without being
processed.
: This shows that the device is not operating.

No.2 DSP THROUGH
The input is automatically discriminated by signal detection and switched with priorities AC3>PCM
Audio>analog. There are the following three submenus.
1. YSS908-SRAM
MAIN L/R are input to the DSP via AC3Dav, pass through SRAM, and are then output to all channels without
being processed. (Remote control code 7A-89)
2. YSS908
MAIN L/R are input to the DSP via AC3Dav, and then output to all channels without being processed.
3. DSP FULL BIT
MAIN L/R are input to the DSP via AC3Dav, and then output to all channels without being processed.
The head margin is disabled, and DSP outputs digital full-bit signals.
Same as the above menu, except that the digital data is output to DA with full bits.

No.6 DISPLAY CHECK
Check program for FL display. The display status will change as follows with submenu operation. The signal is
processed with EFFECT OFF.
All segments are turned on and off to detect defects in the FL driver and FL display segments. Then the FL driver
operation is checked by the dimmer control.
Finally, all segments are turned on and off alternately (in lattice form), to check for a short-circuit between adjacent
segments.
No.7 MANUAL TEST
The noise generator built into the DSP outputs test noise from the channel specified by the submenu.
No.8 FACTORY PRESET
The menu is used to reserve whether or not to set the back-up data for the effect level, delay time and so on to the
factory preset state. The Signal is processed with EFFECT OFF.
1.INHIBIT: The back-up data is not initialized.
To keep the data setby the user, check that this mode has
been selected and cancel the self diagnosis function.
2.RESERVED: When the self diagnosis function is canceled, the back-
up data is initialized to the factory preset state.
For the contents of the initialization, refer to page 20.
The protection data is also reset.

IEC958: Standard to identify the PCM bit stream signal. Digital format error refers to a digital signal with the
sampling frequency undefined (neither 44.1k, 32k nor 48k). Since the operation of each device cannot be
assured at fs outside specifications, the sub-microprocessor handles this status as the forced analog mode
(ignored even if decoding is OK from the detection terminal level), and selects the signal from the analog input
terminal. Since the sub-microprocessor transmits 000B (analog) for STATUS#0 bits 4-6 to the main
microprocessor, the main microprocessor visually operates in the same way as with digital unlocking.
