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 are 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.

Description of the submenu as follows:

No.8 FACTORY PRESET

The initialization of the back-up RAM, which contains, the DSP program, set menu contents, etc. is reserved
or inhibited. Signal route is the same as "2. EFFECT OFF" of "No.4 PRO LOGIC".

1. INHIBITED: Inhibits initialization of the back-up RAM.

8 PRE S E T I NH I Specify this option protect user set values.

2. RESERVED: Reserve to initialization of the back-up RAM.

8 PRESET RSRVD (The RAM is actually initialized when power
is turned on next time.) Specify this option
at the factory preset or to reset the RAM.
For the contents of the initialization, see page 20.
The protection data is also reset.

Caution : Before setting to the PRESET RESERVED, write down the existing preset memory contents of the Tuner in
a table as shown below. (This is because setting to the PRESET RESERVED will cause the memory contents
to be as factory set, i.e., all the preset memory by the user will be erased.)

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
