FOREWORD

Your Marantz product has been specially prepared to comply with the household power and safety requirements that exist in your region. This product has a 2-position voltage selector (110-120/220-240V) on the bottom panel (A, N and T versions). Since the voltage has been adjusted as shown below upon shipment from the factory, please check the third alphabetical letter of the serial number and refer to the following table to note the characteristics of the model in your possession:

SUFFIX VOLTAGE

A -	240V AC, 50/60 Hz
C -	120V AC, 60 Hz
U -	120V AC, 60 Hz
N -	220V AC, 50/60 Hz
T -	240V AC, 50/60 Hz

FOR UNITS SOLD IN THE UNITED KINGDOM

The wires in the mains lead are colored in accordance with the following code:

Blue Neutral

Brown -Live

As the colors of the wires may not correspond with the terminal identification in your plug, proceed as follows:

• Connect the brown wire to the terminal marked "N" or colored brown or red.
• Connect the blue wire to the terminal marked "L" or colored blue or black.

For 13A plug, conforming to BS1363, use a 3A fuse.

For other plugs, use a 5A or lower fuse in the plug or adaptor or at the distribution board.

ABOUT THIS MANUAL

Refer to the figures given on page 3. The callout numbers correspond to those found in this manual. All references to the connections and controls are printed in BOLD-FACE type as they appear on the unit.

REAR PANEL CONNECTIONS

All connections to the rear panel should be made with the power to the entire system turned off. To avoid confusion, connect one cable at a time between the different components of your system. This is the safest way to avoid cross-connecting channels or confusing signal inputs with outputs.

Since the loop antenna is not connected to the tuner, begin installation by installing the loop antenna. (See Figure 6)

(1) FM ANTENNA

Included in the accessory kit is a ribbon-type "folded dipole" FM antenna which should be connected to the terminals marked "300Ω". This type of antenna is simple and practical and will give adequate results in primary signal areas. If you are located in a fringe signal area, an outdoor antenna will be necessary. Even if you live in a strong signal location, an outdoor directional antenna will give you better results.

We do not recommend using master antenna systems, such as those found in apartment buildings. Such systems are usually designed expressly for television reception and frequently suppress or reduce the quality of the FM signals before distribution.

Where outdoor antennas are prohibited or inconvenient, the simplest from of "rabbitear" TV antenna is the most practical and will give satisfactory results. This type is preferred over the folded dipole because it can be more readily rotated for the best reception.

OUTDOOR AM ANTENNA

Two single wires are required to make an AM outdoor antenna. First, connect one single wire to the AM ANTENNA terminal on the rear panel, and the other end to a very high horizontal antenna wire of 7 to 20 meters in length suspended between insulators in an outdoor location (the higher the better). Next, connect the second single wire between the G terminal of your tuner and an authenticated earth ground.

③ AM LOOP ANTENNA

Your tuner is equipped with a high performance, noise-free AM LOOP ANTENNA held on the rear panel with a snap-in hinge. Swivel it out for best AM (MW, LW) reception as shown in figure 4. For improved AM (MW, LW) reception remove the antenna from the hinge and hang it on a nearby wall. The length of the antenna cord is 60~cm and it should not be pulled tight.

• For Model ST430L

AM LOOP ANTENNA CONNECTION

Securely connect the loop antenna leads to the AM and G terminals of the "ANTENNA TERMINAL" of the unit as shown in Fig. 4.

(4) OUTPUT JACKS

Connect the output jacks to the Tuner inputs of your amplifier with the cord supplied.

5 SCAN STEP SELECTOR

Changes the step when the tuner searches for the next station up and down the scale. In Europe this switch should be set for 50 kHz steps in FM and 9 kHz steps in AM.

CAUTION

THE UNIT MUST BE TURNED OFF BEFORE CHANGING THE SCAN STEP SELECTOR SWITCH POSITION.

6 FM DE-EMPHASIS SWITCH

A, N and T version models are equipped with switchable de-emphasis. In synthesizer models the switch works together with scan step switch.

The de-emphasis is set on 50~ s when delivered from the factory. The tuner can also be used in areas of 75~ s . In these areas, you must also set the scan step switch to FM 100 kHz and AM to 10 kHz.

7 AC POWER CONNECTION

The correct voltage for operating your.
tuner is written on the rear panel. Besure the POWER push-switch is out before plugging the AC line cord into an electrical outlet.

The voltage selector is installed on bottom side of the unit.

The AC mains-switch is secondary connected and doesn't disconnect the unit from the AC mains in "OFF" position.

FRONT PANEL FEATURES

8 POWER/STANDBY SWITCH

When depressed supplies AC power to the unit.

9 FREQUENCY/MODE INDICATOR

The frequency received is indicated on the FREQUENCY DISPLAY. The tuner mode is also indicated as follows:

AM or FM: Indicates the band being received.

MHz or kHz: Indicates the unit of the frequency received: MHz for FM and kHz for AM (MW, LW*).

• For Model ST430L

10 FMSTEREO

Lights up when a stereo broadcast is received.

11 SIGNAL STRENGTH

Indicates the strength of the incoming signal: the greater the number of LED's lit, the stronger the signal.

12 BAND SELECTOR

Press the corresponding key to select FM or AM (MW, LW).
For Model ST430L

13 ELECTRONIC TUNING SWITCHES

When the UP or DOWN switch is depressed with the SCAN MODE switch set to MANUAL the frequency is scanned up or down in single steps in accordance with the position of the SCAN STEP SELECTION switch. When the UP or DOWN key is pressed for more than 0.5 sec and the SCAN MODE switch is set to AUTO the frequency is scanned up or down continuously.

14 SCAN MODE

When in the OUT position automatic scanning is performed.

When in the IN position manual scanning is performed.

15 MODE SWITCH

When it is set to the OUT position the MODE is put into STEREO.

When it is set to the IN position the MODE is put into MONO.

When the STEREO indicator triggers intermittently press this switch to convert the signal to the MONO mode.

(16) MEMORY SWITCH

Tune to the desired station, press the MEMORY switch and while the MEMORY light is on (10 sec.) press one of the 8 PRESET buttons.

17 PRESET BUTTONS 1-8

When one of these buttons is pressed the corresponding LED located above the buttons lights and the frequency stored in the corresponding memory is recalled in the mode determined by the position of the BAND selector. It is thus possible to memorize 8 stations each in FM and AM (MW'LW*).

• For Model ST430L

TUNING PROCEDURES

The stereo tuner does not have a conventional tuning dial or tuning knob. There are two tuning methods: Preset tuning and Ordinary tuning.

PRESET TUNING

A total of 16 stations [8AM (MW, LW*) and 8 FM] can be preset. Refer to MEMORY SWITCH on page 6. Turning the tuner On and Off will not cause the tuner to "forget" the stations programmed. Built-in storage capacitors will supply power to the memory circuits for about one week if the unit is unplugged.

• For Model ST430L

ORDINARY TUNING

Refer to ELECTRONIC TUNING SWITCHES page 6.

DESCRIPTION

Set the position of the tuner's loop antenna to obtain the best reception. (See Figure 5)

It is also possible to remove the loop antenna and install it in a separate location. (See Figure 7)
