Notes:
1: Description of the “FM IF Adjustment” is not carried on this
Manual. It is because the IF coil in the FM front end section
has been best adjusted in the factory so that its further
adjustment is not needed at the field. When replacing the
FM front end assembly, no adjustment is needed either.
2: The parts in the FM front end section are prepared in a

EXPLANATION OF DOLBY SURROUND PRO LOGIC AND EVALUATION METHOD
Outline
l
l
Namely, two speakers are connected in parallel to one
amplifier.
l
In the Pro Logic BYPASS mode the amplifierfor C-ch (center
channel) and the amplifier for S-ch (surround channel) are in
MUTE state. The SP output is cut.
l
State of element output and terminal output in specific mode
In the normal mode of Pro Logic ON mode the amplifiers for
C-ch
and S-ch are in operative state, so that the SP output
appears.
l
In the Phantom mode of Pro Logic ON mode the amplifier for
C-ch is in MUTE state, so that the SP output is cut. The
amplifier for S-ch (surround) is in operative state, so that the
SP output appears

NOTES ON SCHEMATIC DIAGRAM
l
Resistor:
To differentiate the units of resistors, such symbol as K and
M
are used: the symbol K means 1000 ohm and the symbol
M
means 1000 kohm and the resistor without any symbol is
ohm-type resistor. Besides, the one with “Fusible” is a fuse
type.
l
Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means micro-micro-farad and the unit of the
capacitor without such a symbol is microfarad. As to
electrolytic capacitor, the expression “capacitance/withstand
voltage” is used.
(CH), (TH),
(ML): Mylar type
(P.P.): Polypropylene type
