● FL display at start-up of diagnostic program

When the diagnostic program has started, the check sum of the main microcomputer or the protection history (*)
is displayed. If the protection function has been activated in the past, the type and voltage value are displayed.
After a few seconds the diagnosis function menu will appear.

(*) If a faulty condition is detected such as excessive current, a bad power supply or excessive amplifier DC offset,
the Power will be switched OFF automatically.

NOTE: For the voltages of the power and DC protection functions, see the diagnosis main menu No. 9, which will be

describbed later. The protection history will be cleared when «RESERVED» is selected in the diagnosis main menu
No. 8 and FACTORY PRESET is engaged.

● Protection history function

The following examples show how the protection history is displayed:

CHK

SUM: XXXX X

IPROTECTION

PS PRT : XX%

DC PR T : XX%

Appears when the protection function has not been activated.
Displayed the check sum (4-digit, hexadecimal) and the version (one
letter) of the main microcomputer.

Appears when the current protection function has been activated.
When power is turned on in an abnormal condition, the power relay
will come on, protection will operate immediately, and power will
turn off.

Appears when the power supply protection function has been activated.
For the % value, the voltage at that point is shown by 5V/100%.
When power is turned on in an abnormal condition, power will turn off
after half a second.

Appears when the power amp DC protection function has been
activated.
For the % value, the voltage at that point is shown by 5V/100%.
When power is turned on in an abnormal condition, power will turn off
after two seconds.

D. Exiting method

The diagnosis function can be exited by any of the following procedures. Take care with the setting of backup memory
initialization menu (diagnosis No. when releasing the diagnosis function.

1. Select sub-menu No. 3 «EXIT» of the diagnosis main menu No. 12.

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 playbac k 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:

1 MAIN:SML 0DB Verification of the High and low pass filter response and gain in the bass redirection mode.
2 MAIN:LRG 0DB Reference of the sub menu No. 1 and 2.
3 MAIN:LRG -10 Verification of the effect in the main level function.
4 B:MAIN C:NONE Verification of the mixing circuit effect to the main channel.
5 LFE/B:MAIN Verification of the bass mix gain.
6 LFE/B:SWFR Verification of the LFE maximum output.
7 C:NONE Verification of the center mix gain.
8 C:S REAR:S Verification of the high and low pass filter response and gain in the bass redirection mode.
9 FRONT MIX Verification of the front mix gain.

SUB MENU DESCRIPTION

Картинка с сайта: manualmachine.com

No.6 DISPLAY CHECK

Check program for FL display. The display status will change as follows with sub-menu operation.

The input becomes «6CH EXTERNAL» when all segments turn off and changes to «6CH MAIN IN»
when all segments turn on.

6. VFD

Initial display

(Remote control code 7D-1D:»EFFECT» key)

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.

8. PRES E T RSRVD

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.

No.9 AD DATA CHECK

The A/D conversion values of the microcomputer which detects key scan port, protection detection port, etc. are displayed
in % (100%:5V).
The keys on the main unit cannot be operated to detect the values of all keys in the K1/K2 and SI.
Turning the rotary encoder (input selector on the main unit) will switch the sub-menu.

Cautions:

1. If K1 and K2 are more than ±4% from the reference values, normal operation will not be executed.

2. If DC and PS are outside the nor mal values, the protection function will operate and power will turn off.
