How can I set radio presets?
Tune to the desired station, then press and hold the MEMORY button. Use the preset buttons (1-8) to select a memory slot. Press MEMORY again to store.
What is RDS and how do I use it?
RDS (Radio Data System) displays station information like station name and song titles. Press the RDS button on the remote to cycle through modes: PS (station name), RT (radio text), CT (time), etc.
Can I connect a turntable with a moving magnet cartridge?
Yes, the Phono input supports MM (moving magnet) cartridges. Connect your turntable's ground wire to the GND terminal to reduce hum.
How do I clean the front panel and controls?
Turn off the unit and unplug it. Use a soft, lint-free cloth slightly dampened with water or a mild detergent. Avoid alcohol, ammonia, or abrasive cleaners. Dry immediately.
Why is there no sound from the speakers?
Check that the SPEAKERS selector is set to A or B. Ensure the MUTE button is not active. Verify input source selection and volume level. Also check speaker wire connections.
Does the GX-900RDS have a headphone jack?
Yes, a standard 6.35mm PHONES jack is located on the front panel. Plugging in headphones automatically mutes the speakers.
How can I improve FM reception?
Use an external FM antenna (75 ohm coaxial). Extend the supplied dipole antenna fully. For weak signals, try rotating the antenna or moving it away from electronic devices.
What is the power consumption in standby?
The standby power consumption is approximately 0.5 W, meeting energy-saving standards.
My remote control is not working. What should I do?
Replace the batteries (2 x AAA). Ensure there are no obstructions between the remote and the receiver's IR sensor. Point the remote directly at the front panel. If still not working, reset the remote by removing batteries and pressing all buttons for 2 seconds.

Precautions: Read this before operating your system

■ To assure the finest performance, please read this manual carefully. Keep it in a safe place for future reference.
- Choose the installation location of this system carefully. Avoid placing it in direct sunlight or close to a source of heat. Also avoid locations subject to vibration and excessive dust, heat, cold or moisture. Keep it away from sources of hum such as transformers and electric motors.
■ Do not operate this system upside-down. It may overheat, possibly causing damage.
■ Never open the cabinet. If something drops into the set, contact your dealer.
■ The openings on the main unit cover assure proper ventilation of the main unit. If these openings are obstructed, the temperature inside the unit will rise rapidly. Therefore, avoid placing objects against these openings, and install the main unit in a well-ventilated area to prevent fire and damage.
■ Always set the VOLUME control to minimum before starting an audio source play: increase the volume gradually to an appropriate level after play has started.
■ When not planning to use this system for long periods of time (ie., vacation, etc.), disconnect the AC power plug from the wall outlet.
■ Grounding or polarization – Precautions should be taken so that the grounding or polarization of this system is not defeated.
■ Do not use force on switches, controls or connection wires. When moving the main unit, first disconnect the power plug and the wires connected to other equipment. Never pull the wire itself.
■ If an external appliance (TV, radio, etc.) interferes with this system operation, move the main unit away from such an appliance.
■ Do not attempt to clean this system with chemical solvents; this might damage the finish. Use a clean, dry cloth.
■ Be sure to read the "Troubleshooting" section regarding common operating errors before concluding that this system is faulty.
■ To prevent lightning damage, disconnect the AC power plug and the antenna cable when there is an electrical storm.
■ Do not plug the AC power plug to the wall socket before you finish all connections.
- Never allow metallic items (e.g. screwdrivers, tools, etc.) to come near the tape deck's record/playback head assembly. Doing so may not only scratch or damage the head's mirror-smooth finish, it may change the magnetic characteristics of the heads, causing a deterioration in reproduction performance quality.

Although the tape deck's record/playback heads are high quality heads with outstanding reproduction characteristics, they can become dirty through the use of old tapes or from dust accumulation over time. This can have a serious effect on reproduction quality. Clean the heads regularly with one of the commonly available head cleaners or with cleaning solutions.
■ The voltage to be used must be the same as that specified on this system. Using this system with a higher voltage than specified is dangerous and may result in a fire or other types of accidents causing damage. YAMAHA will not be held responsible for any damage resulting from use of this system with a voltage other than specified.
■ The sound level at a given volume setting depends on speaker location and other factors. Care should be taken to avoid exposure to sudden high levels of sound, which may occur when turning on this system with the volume control setting at high, and to continuous high levels of sound.
■ Sudden temperature changes and storage or operation in an extremely humid environment may cause condensation inside the cabinet. Condensation can cause this system to malfunction.

To eliminate condensation:

• CD pickup/MD pickup

Leave the power on with no disc loaded until normal play becomes possible (about 1 hour).

- Tape head

Leave the power on with no tape loaded until normal playback becomes possible (about 1 hour).

Note

If condensation forms on the tape head, dirt or dust may accumulate during use.

- Remote control

Wipe off condensation on the transmission window with a soft cloth before operating this system.

■ To prevent a malfunction of this system:

  • Do not use any non standard shaped compact disc (heart etc.) available on the market, because it may damage this system.
  • Do not use a compact disc with tape, seals, or paste on it, because damage to this system may result.

This system is not disconnected from the AC power source as long as it is connected to the wall outlet, even if this system itself is turned off. This state is called the standby mode.

In this state, this system is designed to consume a certain level of power.

Note

Please check the copyright laws in your country to record from records, compact discs, minidiscs, radio, etc. Recording of copyright material may infringe copyright laws.

Precautions: Read this before operating your system

CAUTION FOR CARRYING THE MAIN UNIT

Memory back-up

The memory back-up circuit prevents the programmed data from being lost even if the AC supply lead is disconnected from the AC outlet or the power is cut due to temporary power failure. If, however, the power is cut for more than one week, the memory may be erased. If so, it can be re-programmed by simply following the Preset tuning steps.

Automatic preset tuning

You can make use of an automatic preset tuning function. With this function, the built-in tuner performs automatic tuning. Up to 40 stations are stored automatically.

1 Turn on the power.
2 Press INPUT ▷ or ▶ until "TUNER" (②, ⑧) appears on the display, or simply press TUNER on the remote control.
3 Press and hold MEMORY for more than 2 seconds. * The "MEMORY" (⑥) and "AUTO" (④) indicators flash.

The tuner performs automatic tuning and searches FM and AM stations in that order. Received stations are programmed to A1, A2 ... A8 sequentially.

When the automatic preset tuning is completed;

The display shows the frequencies of the first preset station (stored to A1).

If you want to check the contents and the number of preset stations, follow the procedure of the section "To recall a preset station" on the previous page.

To recall a preset station

Simply follow the procedure of the section "To recall a preset station" on the previous page.

Notes

  • The automatic preset tuning search will be performed through all frequencies until 40 stations are stored. If the number of received stations is less than 40, the search will stop after searching all frequencies.
    * Since FM stations are searched for first, there may be a case that 40 preset stations are occupied by FM stations only.
  • The tuner is originally set to search only RDS stations instead of all FM stations by this operation. (FM stations that employ no RDS network service cannot be programmed.)
    However, you can change the setting so that the tuner can program not only RDS stations but also other FM stations. (Refer to page 21 for details.)
  • With this function, only stations with sufficient signal strength are stored automatically. If the station you want to program is weak in signal strength, tune in to it with the Manual tuning method (in monaural) and program it by following the procedure of the section "To store stations" on the previous page.
  • You can replace a preset station with another FM or AM station manually by simply following the procedure of the section "To store stations" on the previous page.

Tuning operation

Receiving RDS stations

RDS (Radio Data System) is a data transmission system employed by FM stations in many countries. Stations using this system transmit an inaudible stream of data in addition to the normal radio signal.

RDS data contains various information, such as PI (Program Identification), PS (Program Service name), PTY (Program Type), RT (Radio Text), CT (Clock Time), etc.

RDS function is carried out among the network stations.

* The built-in tuner utilizes PS, PTY, RT and CT to receive RDS broadcast stations.

■ RDS modes

The built-in tuner uses the following four modes to display RDS data.

PS (Program Service name) mode

PTY (Program Type) mode

There are 15 program types to classify RDS stations as described below.

RT (Radio Text) mode

CT (Clock Time) mode

PTY modes

■ Changing the RDS modes

When an RDS station is received, by pressing FREQ PS/PTY/RT/CT once or more, you can change the display mode among the RDS modes employed by the received station in the order shown on the next page. (The RDS mode not employed by the station cannot be selected.)

Notes

  • If the received station is not an RDS station, pressing FREQ PS/PTY/RT/CT displays "NO RDS" on the display, and then it returns to the frequency display mode.
  • When an RDS station is received, the display is automatically turned into the PS mode. Do not press FREQ PS/PTY/RT/CT until the display is turned into the PS mode. If the button is pressed before the display mode changes, it may occur that "NO PS" appears on the display. This is because the tuner has not received all of the RDS data on the station yet.

YAMAHA GX-900RDS - Notes - 2

The tuner corrects the time of the built-in clock by synchronizing it with the CT data. (This function can also be canceled, if so desired. Refer to page 21 for details.)

* "CT WAIT" may flash while the tuner is receiving the data. If the data is accidentally cut off, "CT WAIT" may flash and then turn into "NO CT".
* If the RDS station does not employ the CT data service, "NO CT" lights up on the display for about 2 seconds and then returns to the frequency display mode. If the station has PS data, after that, it turns into the PS mode.

Notes

  • RDS data service cannot be used if the received signal is not strong enough. Especially, the RT (Radio Text mode) needs much data to be received, so it may occur that RT mode cannot be displayed even if other RDS modes (PS, PTY, etc.) are displayed.
  • There may be a case that RDS data reception is not possible due to poor reception conditions. In such a case, press AUTO/MANUAL to make tuning manually. Though the reception mode is changed to monaural by this operation, when you change the display to an RDS mode, RDS data may be displayed.
  • If the signal strength gets weakened by external interference during receiving an RDS station, the RDS data service may be cut off suddenly and turn into the frequency display mode.

■ Calling a program of your desired program type from among preset RDS stations (PTY SEEK)

By designating a program type, the tuner automatically searches all preset FM stations for an RDS station which broadcasts a program of that program type.

* There are 15 program types to classify RDS stations. For details, refer to page 18.

1 Turn the tuner into the PTY SEEK mode by pressing PTY SEEK MODE.

* The name of the program type of the station now being received or "NEWS" flashes on the display.

2 Select the desired program type by using PTY SELECT √ or ↗

* If there is no operation for about 20 seconds, this mode is canceled and turns into the frequency display. If the station has PS data, after that, it turns into the PS mode.

3 Press PTY SEEK START.

The tuner begins searching all preset FM stations.

* "PTY HOLD" (⑦) lights up on the display.
* The name of the program type and "AUTO" (④) flash. The preset station number (①) changes rapidly in sequence.

  • If a station which broadcasts a program of the program type is found, the search stops at the station and turns into the frequency display. If the station has PS data, after that, it turns into the PS mode.
  • If the called station is not the desired one, press PTY SEEK START once more. The tuner begins searching for another station which broadcasts a program of the same program type.
  • If no station is found, "NO PTY" appears and then returns to the frequency display. If the station has PS data, after that, it turns into the PS mode.

* If PTY SEEK START is pressed once more during searching, this mode is canceled ("PTY HOLD" disappears) and turns into the frequency display. If the station has PS data, after that, it turns into the PS mode.

To cancel the PTY SEEK mode

If PTY SEEK MODE is pressed twice, the PTY SEEK mode is canceled and turns into the frequency display. If the station has PS data, after that, it turns into the PS mode.

■ Other functions which make use of RDS data service

The tuner has the following functions which make use of RDS data service. These are originally in operation [ON].

However, you can cancel these functions [OFF], if so desired.

1 ON CT>CLOCK 2 ON LOCAL>CT 3 ON A.M.-RDS 3, 6 1 2 3 4 5 6

1 ON (OFF) CT > CLOCK

The tuner corrects the time of the built-in clock automatically by synchronizing it with the CT data on the RDS station being received.

* If you receive an RDS station of some other country, the built-in clock is synchronized with the time setting of the country.
* If the built-in clock is not yet set for the current time or reset due to a power failure etc., it will be set for the time of the CT data automatically, whether this setting is ON or OFF.

If the RDS station being received employs the local time (summer time etc.) data service, its time is displayed in the CT mode.

* If the setting of function 1 is "ON", the built-in clock is synchronized with the local time data.

3 ON (OFF) A. M. - RDS (AUTO MEMORY > RDS)

Only RDS stations are searched instead of all FM stations by the automatic preset tuning operation when the setting is ON. (Refer to page 17 for the operating procedure.) If you switch this function OFF, not only RDS stations but also other FM stations are programmed along with AM stations by the automatic preset tuning operation.

To switch these functions on and off

1 Select the FM band by pressing the PRESET/TUNING/BAND, confirming it on the display.
2 Press DISPLAY to display the current time.
3 Press FREQ PS/PTY/RT/CT.

The title of function 1 "ON CT > CLOCK" is displayed.

Dolby B Type Noise Reduction

Dolby noise reduction is an extremely effective method of reducing undesirable background hiss on tapes. The built-in tape deck incorporates Dolby B type noise reduction system. DOLBY NR is useful to both recording and playback; be sure that the same noise reduction is used on recording and playback.

Dolby noise reduction manufactured under license from Dolby Laboratories Licensing Corporation. "DOLBY" and the double-D symbol □ are trademarks of Dolby Laboratories Licensing Corporation.

  • Do not use C-120 tapes or poor-quality tapes, since they can cause malfunctions.
  • Before loading a tape on the tray, tighten the tape slack with a pen or pencil.
  • Tapes have removable tabs which prevent accidental recording or erasing from taking place. Removing the tab on the top left protects the side facing you from erasure. Cover the tab holes with adhesive tape to erase or record again.
  • The tape deck features an automatic tape selector. Just load the tape, and the tape formula being used will be sensed automatically.
  • The tape deck can play back metal tapes as well as normal or chrome tapes, however recording cannot be done on metal tapes with good sound quality.

About the tape counter

The tape deck is equipped with a tape counter that is useful for searching and locating a desired point on the tape. The tape counter is shown on the display.

M-MARK INPUT MODE YAMAHA

Track-marking

The MD recorder provides both automatic and manual methods for the track number-marking.

• Automatic (default setting)

When making a recording, the track-marking is made automatically.

• Manual

To make the track-marking manually, press M-MARK on the remote control repeatedly until "MANUAL" (8) is illuminated.

When recording analog signals (from tapes, radio programs, etc.)

Automatic:

Track numbers are written in synchronization with the input level of the signal being recorded. During recording, if no sound is detected for more than 1.5 seconds, the recorder interprets this to be a gap between two tracks. When the source signal is detected again, a track number is automatically written.

Manual:

One track number is written automatically when you start recording, but none are written during recording. To mark a track number, press M-MARK at the desired position while recording.

Note

When using the manual method, the marks must be set at least 4 seconds apart.

When recording digital signals (from CDs, etc.)

Track numbers are written in the same positions as the original source (CDs, etc.) with either automatic or manual track-marking method.

To add additional track numbers, select the manual track-marking method and press M-MARK at the desired position while recording.

TOC (Table of Contents) is the non-audio data contained on all minidiscs (track numbers, play time, title data, etc.) When you make recording onto an MD, the TOC data is automatically renewed.

When the message “TOC Reading” or “TOC Writing”, etc. is shown on the display, it means that the MD recorder is reading the TOC data on an MD, or recording TOC data onto an MD. During this period, do not make an operation on the MD recorder, do not disconnect the power cord of this system, or do not shake this system to prevent a misoperation of the MD recorder.

One of the main advantages of MD is its editing capabilities, you can remove the commercials from a radio broadcast, arrange songs into the order you want, remove songs, combine songs, even remove part of a song.

The MD recorder offers the following editing functions.

- Erase

Lets you erase a track, the entire disc, or part of a track.

You can also erase the title of a disc, or the titles of tracks on a disc.

- Move

Lets you move a track to a different track number.

- Combine

Lets you combine two adjacent tracks.

- Divide

Lets you split a single track into two different tracks.

- TOC Write

Lets you write TOC information to the disc so that changes are saved.

- FRA Check

Lets you recover disc space that may have been lost after repeated editing operations.

- Undo

Lets you undo the previous editing operation if you make a mistake.

Notes on editing

Before editing

MD system limitations

The recording system in your MD recorder is radically different from those used in tape and DAT decks and is characterized by the limitations described below. Note, however, that these limitations are inherent to the MD recording system and are not a result of mechanical trouble.

"Can't REC" is displayed before the maximum recording time (60 or 74 minutes) has been reached

Once 255 tracks have been recorded on one MD, "Can't REC" is displayed regardless of the total recorded time.

"Disc Full" is displayed before the maximum number of tracks (255) have been recorded

During Automatic track-marking, fluctuations in emphasis within songs may be interpreted as song intervals, increasing the total number of tracks and causing "Disc Full" to be displayed.

The remaining recording time does not increase even after erasing numerous short tracks

Tracks under 12 seconds in length are not counted and so erasing them may not lead to an increase in the recording time.

"TOC Reading" is displayed continuously

The "TOC Reading" display lasts longer than normal when a brand new (blank) disc is inserted.

The total recorded time and the remaining time on the MD do not total to the maximum recording time

  • Recording is done in minimum units of 2 seconds each, no matter how short the material.
  • The MD recorder displays the length of the largest continuous blank area as the remaining time. Therefore, if there are several separate blank spaces, the remaining time will only display a time equivalent to the largest continuous blank space.

Tracks created through editing may exhibit sound dropout during search operations.

Track numbers are not recorded correctly

Incorrect assignment or recording of track numbers may result when CD tracks are divided into several smaller tracks during digital recording.

It is not possible to erase part of a track using the A-B Erase function

The MD recorder organizes the audio data in sound groups and clusters. The minimum size of these units may not consist of less than 10 seconds of stereo sound.

The correct recorded/playing time may not be displayed during playback of MDs recorded in monaural.

Copy protection (SCMS)

As a digital audio component, this MD recorder conforms with the Serial Copy Management System (SCMS) standards. The Serial Copy Management System restricts copies made by recording digital signals to the first-generation copies only. Therefore, an MD recorded from a digital input source cannot be used as a source for making another digital recording.

Can't REC!

Timer recording is not possible. The loaded disc may be protected or there may not be enough blank space remaining on the disc.

Can't REC

Recording is not possible because there is not enough blank space remaining on the disc.

DIGin Unlock

No digital signal is being input to the DIGITAL IN (OPTICAL) terminal.

Disc Full

Recording is not possible because there is no blank space remaining on the disc.

Title Full

Additional characters cannot be input for the current title because the maximum number of characters for a single title (250) have already been input.

UTOC WError

Error occurred when writing to the TOC.

Not Audio

The inserted disc is not an audio MD.

Tr Protected

The selected track cannot be edited because it is protected.

TOC Full

The disc area allotted for TOC data has become full and further editing is not possible.

UTOC ERR L...

Problem involving user's TOC data.

TMP Over!!
