① FM antenna terminal (75 ohms)

Connect an external FM antenna with a coaxial cable, or a cable network FM source.

② AM antenna and ground terminals

Connect the supplied AM loop antenna. Use the terminals marked "AM" and "GND". The supplied AM loop antenna will provide good AM reception in most areas. Position the loop antenna until you hear the best reception.

③ AUDIO OUT connectors

The audio signals are output from these connectors.

④ REMOTE CONTROL IN and OUT connectors

Using the supplied remote control connecting cord, these connectors enable this unit to be connected to a Marantz component equipped with remote control connectors. These connections make it possible to control an entire system that centers on the amplifier or other such component.

⑤ AC INLET

Plug the supplied mains cord into this AC INLET and then into the power outlet on the wall. ST6003 can be powered by 230V AC only.

BASIC CONNECTIONS

CONNECTING THE AMPLIFIER

Use the audio connecting cord to connect the unit with a stereo amplifier or AV amplifier.

Cautions:

• Do not connect the unit to the PHONO input connectors on the amplifier.
• When making the connections, insert the plugs securely into the connectors. Failure to insert the plugs securely may result in noise.

Notes:

• Do not plug in the mains cord until all connections have been completed.
• When making connections, also refer to the operating instructions of the other components.
• Be sure to connect the left and right channels properly (left with left, right with right).
• Note that binding pin-plug cords together with mains cords or placing them near a power transformer will result in generating hum or other noise.

CONNECTING THE ANTENNA TERMINALS

ASSEMBLING THE AM LOOP ANTENNA

1. Release the vinyl tie and take out the connection line.

1. Bend the base part in the reverse direction.

1. Insert the hook at the bottom of the loop part into the slot at the base part.

1. Place the antenna on stable surface.

CONNECTING THE SUPPLIED ANTENNAS

Connecting the supplied FM antenna

The supplied FM antenna is for indoor use only. During use, extend the antenna and move it in various directions until the clearest signal is received.

Fix it with push pins or similar implements in the position that will cause the least amount of distortion. If you experience poor reception quality, an outdoor antenna may improve the quality.

Connecting the supplied AM loop antenna

The supplied AM loop antenna is for indoor use only.

Set it in the direction and position it to where you receive the clearest sound. Put it as far away as possible from the unit, televisions, speaker cables, and power cords.

If you experience poor reception quality, an outdoor antenna may improve the quality.

1. Press and hold down the lever of the AM antenna terminal.
2. Insert the bare wire into the antenna terminal.
3. Release the lever.

CONNECTING AN FM OUTDOOR ANTENNA

Notes:

• Keep the antenna away from noise sources (neon signs, busy roads, etc.).
• Do not put the antenna close to power lines. Keep it well away from power lines, transformers, etc.
• To avoid the risk of lightning and electrical shock, grounding is necessary.

CONNECTING AN AM OUTDOOR ANTENNA

An outdoor antenna will be more effective if it is stretched horizontally above a window or outside.

Notes:

• Do not remove the AM loop antenna.
  • To avoid the risk of lightning and electrical shock, grounding is necessary.

CONNECTING THE AC POWER CABLE

1. Plug the supplied AC power cable to the AC IN socket on the rear panel of the main unit.

RDS OPERATION

Now in use in many countries, RDS (Radio Data System) is a description of the station's programming hidden space in the FM signal.

This unit is equipped with RDS to assist in the selection of FM stations using station and network names, rather than broadcast frequencies. Additional RDS functions include the ability to search for programme types.

RADIO TEXT

Some RDS stations broadcast RADIO TEXT, which is additional information on the station and programme being broadcast.

RADIO TEXT Information appears as 'running' text in the display. RADIO TEXT is transmitted character by the radio station. As a result of that it may take some time until the entire text has been completely received.

RDS DISPLAY

When this unit is tuned to an FM station that is transmitting RDS data, the Front Panel Information Display will automatically show the station name or RADIO TEXT in place of the typical display of the station's broadcast frequency.

To change the display, press the DISPLAY button.

PS (Program Service Name) Frequency(RADIO TEXT)

PROGRAMME TYPE (PTY) DISPLAY

The RDS system categorizes programmes according to their genre into different programme type (PTY) groups. To display the programme type information of the current station, press the F/P button for 3 seconds or more.

PTY AUTO SEARCH

This unit is equipped to automatically search for stations transmitting any of 29 different programme types. To search for a PTY, follow these procedures:

2.1.3.4.

1. Press the F/P button for 3 seconds or more. The current station's PTY will be displayed, or the currently selected PTY group will be displayed in blinking if no station or RDS data is present.
2. To change to a new PTY type, press the ▲ or ▼ button on the front panel until the desired PTY is shown in the display.
3. Once the desired PTY group or type has been selected, press the F/P button while the display blink (approx. 5 seconds). The PTY Auto search will start, and the tuner will pause at each station broadcasting RDS PTY information corresponding to the selected choice.
