The FM multiplex circuitry includes a phase
locked loop, Stereo-Monaural Automatic switch-
ing circuit, stereo indicator circuit and a buffer
amplifier to obtain output power at low im-
pedance. Low pass filters for 19KHz and 38KHz
rejection are incorporated. Moreover, the Model
4300 unit has a muting circuit that permits pleas-
ant FM broadcast reception by completely elimi-
nating inter-station interference which is usually
generated at the time of selecting FM stations.

To obtain optimum performance and enjoyment
from the Model 4300, please study these instruc-
tions carefully. Follow the step-by-step instruc-
tions to obtain maximum performance.
This manual is divided into two parts. The first

cations and functional explanations.
GENERAL DESCRIPTION
Your Marantz Model 4300 is a high-quality Stereo
2
+
Quadradial 4 Receiver developed by Marantz,
a name famous for quality in the audio com-
ponent industry. The Model 4300 incorporates
Marantz' exclusive Vari- Matrix circuit which sim-
ulates 4-channel sound from normal 2-channel
stereo programs, and is capable of reproducing
4-channel sound from any matrix-encoded source.
The 4300 will also reproduce any discrete 4-
channel program as well as regular stereo and
monaural programs. An optional plug-in decoder
adapts the 4300 for any specific matrix system,
such as Columbia's SQ.
The FM tuner section employs an FET for the
RF amp stage. The IF tuning circuit employs
ceramic filters of wide bandwidth and high
selectivity to provide high sensitivity and un-
paralleled interference-free operation.
The 4300 incorporates a full-process, 2-channel
DOLBY System to reduce noise, inherent in
recording music from records, tape, FM broad-
casts and TV.
For quick identification of the controls and
connections, references are printed in bold face
type.
AFTER UNPACKING
It is advisable to save all original packing material
to prevent damage should you wish to transport
or ship the Receiver (refer to Figure 15 for pack-
ing instructions). Please inspect your Model 4300
carefully for any signs of damage in transit.
It has undergone stringent quality control inspec-
tion and tests prior to packing, and left the
factory in perfect operating condition. If the
unit is damaged, notify the carrier without delay.
Only the consignee may institute a claim with
the carrier for damage during shipment. How-
ever, the Marantz Company will co-operate fully
in such an event. Save the damaged carton as
evidence for inspection by the carrier.
