7.3.3 Service Mode For DSP Amplifier
1. Outline
This specifications details operation according to our
suggestion for answering complaint about sound
quality in audio systems. It is based on an assumption that a dealer or service person operate the product to solve the problem.
2. Sound Quality Service Mode Function
Sound Quality Service mode has the following functions:
1 Frequency characteristics adjustment : Specifies
two points (frequency/dB value) of equalizer (EQ)
to adjust frequency characteristics. Also adjusts
attenuation.
2 Level adjustment : Adjusts sound levels of the
front and rear speakers and woofer.
3. Activating Sound Quality Service Mode
Use the following steps to activate Sound Quality
Service mode.
1 Confirm that ACC is ON, then activate Dialogue
mode.
(Operate according to the method of activation of
diagnosis mode specified for the system.)
2 Press the [AM] button of H/U in the MENU screen
in Diagnosis mode .
The system enters Sound Quality mode. Then, the
system beeps one time and displays “AUDIO.” You
cannot return to Dialogue mode by pressing a button
from Sound Quality Service mode.
4. Canceling Sound Quality Service mode
Setting ACC to OFF cancels Sound Quality Service
mode. After that, the system will maintain sound
quality set in Sound Quality Service mode.

5. Details
1 Frequency characteristics adjustment function
• The system changes submodes cyclically every
time the [FM1/2] button is pressed when
"AUDIO" is displayed.
Set EQ Point 1 t Set EQ Point 2 t Set attenuation t "AUDIO"
• Set EQ Point 1
The system displays “P1” and EQ management
number. The EQ management number
ascends/descends every time the UP/DOWN button is pressed.The EQ management number consists of three digits (000 to 286). Initial value is
000 (no setting).
• Set EQ Point 2
The system displays “P2” and EQ management
number. The EQ management number
ascends/descends every time the UP/DOWN button is pressed. The EQ management number
consists of three digits (000 to 176). Initial value
is 000 (no setting).
• Set attenuation
The system displays “L” and attenuation value.
Use the UP/DOWN button to change attenuation
within a range from 0 to -20 dB at increments of
1 dB. Attenuation value is shown in two digits
from 00 to 20 (20 = -20 dB). Initial value is 00 (no
setting).
38
2 level adjustment function
• The system changes submodes cyclically every
time the [TAPE] button is pressed when "AUDIO"
is displayed.
Set front t Set rear t Set woofer t “AUDIO”
• Set front
The system displays "F" and level value.Use the
UP/DOWN button to change level value within a
range from 0 to -80 dB at increments of 1 dB.
Level value is shown in two digits from 00 to 80
(80 = -80 dB). Initial value is 00 (no setting).
• Set rear
The system displays "R" and level value. Use the
UP/DOWN button to change level value within a
range from 0 to -80 dB at increments of 1 dB.
Level value is shown in two digits from 00 to 80
(80 = -80 dB). Initial value is 00 (no setting).
• Set woofer
The system displays "W" and level value. Use the
UP/DOWN button to change level value within a
range from 0 to -80 dB at increments of 1 dB.
Level value is shown in two digits from 00 to 80
(80 = -80 dB). Initial value is 00 (no setting).
Notes:
1) Pressing the TAPE button during adjustment of frequency characteristics is invalid. Pressing the
[FM1/2] button during level adjustment is invalid.
2) The UP/DOWN button mentioned above means the
[SEEK] key.
