SAFETY

INSTRUCTIONS

READ BEFORE OPERATING EQUIPMENT

This product was designed and manufactured to meet strict quality and safety standards. There are, however, some installation and operation precautions which you should be particularly aware of.

1.Read Instructions — All the safety and operating instructions should be read before the appliance is operated.

2.Retain Instructions — The safety and operating instructions should be retained for future reference.

3.Heed Warnings — All warnings on the appliance and in the operating instructions should be adhered to.

4.Follow Instructions — All operating and use instructions should be followed.

5.Water and Moisture — The appliance should not be used near water — for example, near a bathtub, wash-bowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool, etc.

6.Carts and Stands — The appliance should be used only with a cart or stand that is recommended by the manufacturer.

7.An appliance and cart combination should be moved with care. Quick stops, excessive force, and uneven surfaces may cause the appliance and cart combination to overturn.

8.Wall or Ceiling Mounting — The appliance should be mounted to a wall or ceiling only as recommended by the manufacturer.

9.Ventilation — The appliance should be situated so that its location or position does not interfere with its proper ventilation. For example, the appliance should not be situated on a bed, sofa, rug, or similar surface that may block the ventilation openings; or, placed in a built-in installation, such as a bookcase or cabinet that may impede the flow of air through the ventilation openings.

10.Heat — The appliance should be situated away from heat sources such as radiators, heat registers, stoves, or other appliances (including amplifiers) that produce heat.

11.Power Sources — The appliance should be connected to a power supply only of the type described in the operating instructions or as marked on the appliance.

12.Grounding or Polarization — The precautions that should be taken so that the grounding or polarization means of an appliance is not defeated.

AC POLARIZED PLUG

13.Power-Cord Protection — Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the appliance.

14.Cleaning — The appliance should be cleaned only as recommended by the manufacturer.

15.Power Lines— An outdoor antenna should be located away from power lines.

16.Outdoor Antenna Grounding — If an outside antenna is connected to the receiver, be sure the antenna system is grounded so as to provide some protection against voltage surges and built up static charges. Section 810 of the National Electrical Code, ANSI/NFPA No. 70-1984, provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode. See Fig. 1.

17.Nonuse Periods — The power cord of the appliance should be unplugged from the outlet when left unused for a long period of time.

18.Object and Liquid Entry — Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through openings.

INTRODUCTION

Thank you for selecting the Marantz Model PMD520 3-head Independent Dual Well Cassette Deck.

Please read these operating instructions carefully. We recommend that you read the entire user guide before you connect or operate the unit.

After you have reviewed the contents this manual, we suggest that you make all system connections before you attempt to operate the unit.

Refer to the Figures on Pages 54 – 57 of this user guide.

The callout numbers on the Figures correspond to those found in the text. All references to connections and controls are printed in BOLD type, as they appear on the unit.

PRECAUTIONS

The following precautions should be considered when operating the equipment.

When setting the equipment ensure that :

air is allowed to circulate freely around the equipment

the equipment is on a vibration free surface

the equipment will not be exposed to interference from an external source

the equipment will not be exposed to excessive heat, cold, moisture or dust

the equipment will not be exposed to direct sunlight

the equipment will not be exposed to electrostatic discharges

¡In addition, never place heavy objects on the equipment.

¡If a foreign body or water does enter the equipment, contact your nearest dealer or service center.

¡Do not pull out the plug by pulling on the mains lead. Hold the plug.

FEATURES

¡COMPLETELY INDIVIDUAL DUAL SYSTEM

Well A and Well B can be controlled independently for both recording and playback. There are two sets of inputs and outputs which allow for many modes of recording and playback. Two separate input sources can be recorded simultaneously and independently on the two decks; two different tapes can be played back simultaneously on the two decks; and lastly, it is possible to play a cassette on one well, and record a different source (such as a mixer) on the other well simultaneously.

There are also several modes in which the two decks work together.

¡CONTINUOUS RECORDING AND PLAYBACK

In the continuous mode, Well A will play (or record) side one, and then automatically switch to Well B, which will play (or record) side one. In this way 1-1/2 hours of uninterrupted playback or recording is possible using C-90 cassettes.

¡CASCADE CONNECTION FOR SERIAL CONNECTION OF MULTIPLE UNITS

By connecting several PMD520s in series by way of the cascade connection, multiple units can play or record continuously for logging and other long-time recording applications. In this case, Wells A and B of unit #1 will play (or record) as in the example above, then they will trigger the start of continuous playback (or record) of unit #2, and so on.

¡OVERLAP SERIES RECORDING

This feature records long events such as a conference, without interruption. The recording of the next tape starts when the remaining time on the previous tape is approximately 3 minutes.

¡PARALLEL RECORDING (DUPLICATION)

When multiple copies of the same source are required, it is possible to record both Well A and Well B simultaneously, in parallel, from a single source.

¡TIMER REC/PLAY

Time-activated playback and recording are available using a commercially available timer.

¡FINE SPEED CONTROL

Each Well features ± 3% speed control.

¡METERS AND LINEAR TIME TAPE COUNTERS

Each Well features independent FL bargraph meters, and a linear time (minutes and seconds) counter. The display on these counters is only an approximate indication of minutes and seconds and its accuracy depends on the match between the Tape and the correct TAPE TIME setting.

¡TAPE STOP ALARM

A buzzer sound is generated to indicate the end of tape after playback or recording.

¡DOLBY B/C NR SYSTEMS

The Dolby NR (Noise Reduction) systems compress and amplify signals during recording in order to raise the signal-to- noise ratio on the tape. During playback, these signals are expanded and attenuated by the same amount in order to regain the original dynamic range of the music. An additional result of this expansion and attenuation is that the noise floor of the recording is reduced significantly. Dolby B typically reduces noise by 10 dB, while Dolby C typically reduces noise by 20 dB.

¡DOLBY HX PRO HEADROOM EXTENSION

The Dolby HX PRO system monitors the total amount of effective bias during recording and instantaneously compensates for any excess bias by reducing the deck’s bias signal level accordingly.

The system operates independently on each channel. HX PRO is unlike a noise reduction system because it functions only during recording and no decoding is required. Therefore, a tape recorded with the HX PRO system can be played back on any other cassette deck while retaining the benefits of HX PRO.

Dolby noise reduction and HX Pro headroom extension are manufactured under license from Dolby Laboratories Licensing Corporation. HX Pro originated by Bang & Olufsen.
