No.5 SPEAKERS SET
The input is automatically discriminated by signal detection and switched with priorities Coaxial>Optical>Analog.
The L/R signals are output to channels specified by the sub-menu without being processed.
There are the following nine sub-menus items. Signal routes of the sub-menu 1-4 are the same as EFFECT OFF.
But MAIN L/R are signals through the digital circuit.
Signal routes of the sub-menu 5-9 are the same as "2. YSS M" of "No. 2 DSP THROUGH".
However, only MAIN L/R is output in the sub-menu 1-4.

LARGE: Mode in which speakers with high bass-sound playback capability (large unit) are used.Full-range signals present
on the channel are output from the speaker.
SMALL: Mode in which speakers with low bass-sound playback capability (small unit) are used.Low bass signals (below
90Hz) on the channel are mixed into the channel selected by the LFE/BASS setting.
NONE: Mode in which center speaker is not used.The center channel signal is reduced by 3 dB and mixed into MAIN L/R.
LFE/B:MAIN
:Mode in which subwoofer speaker is not used.The LFE channel signal is reduced by 4.5 dB and mixed into
MAIN L/R. But because of the phase difference, the MAIN L/R output is not simply summed.
The analog switches in each sub-menu are set as follows:

No.6 DISPLAY CHECK
Check program for FL display. The display status will change as follows with sub-menu operation.
A defect of the FL drive port and FL display segments can be detected by using "All segments turn off" and "All
segments turn on".
A short-circuit between adjacent segments can be detected by using "Alternate segments turn on" (lattice form).
No.7 MANUAL TEST
By using the noise generator built into the DSP, test noise outputs to the channel specified by the sub-menu.
No.8 FACTORY PRESET
The initialization of the back-up RAM, which contains DSP program, set menu contents, etc. is reserved
or inhibited.
1. INHIBIT: Inhibits initialization of the back-up RAM.
Using this option protect user set values.
2. RESERVED: Reserve to initialization of the back-up RAM.
(The RAM is actually initialized when power
is turned on next time.) This option is used for
the factory preset or to reset the RAM.
For the contents of the initialization, see page 18.
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 32k,44.1k,48k,64k,88.2k nor 96k). Since the operation of each device
cannot be assured at fs outside specifications, this status handled as the forced analog mode (ignored even if
decoding is OK from the detection terminal level), and the signals from the analog input terminal will be
selected. Bits 4-6 of "CPU/1" will be 000B (Analog), and the microcomputer operates in the same way as with
digital unlocking.
