Professional CD Player

DN-C635

DESCRIPTION

The Denon DN-C635 is a professional CD player housed in a single 2RU rack-mount chassis. It is the successor to the popular DN-C630 and includes many new feature enhancements for professional applications such as CD-RW playback, shock memory and CD text support. Auto Cue to music and instant start insures there are no blank spots at the beginning of the track to be played. A new D-Sub 9 pin port can be configured for either RS-232C or RS-422A communication. An Infra-red sensor has been added behind the front panel for wireless control. Designed for use in a wide range of applications the DN-C635 will satisfy the needs of demanding installations. Radio station, pre-production, post production, studio and theater are just some of the examples where the DN-C635's features will provide solid performance when quality sound is required. For background music applications, the DN-C635 supports MP3 decoding for hours of music playback. Functions on this CD player include a variable pitch of 12% (approximately 2 octaves) and a Single/Continuous Playback mode. The 1x/10x wrap-around track select knob allows for quick track access. A digital SPDIF port is located on the back panel for connecting to digital systems along with sync and cascade connectors for use with multiple DN-C635 units or the DN-780R tape recorder. Digital servo adjustment has been automated so that the optimum setting is always obtained for the type of CD being played, compensating for any changes occurring in the pickup over years of use.

Second and Subsequent Units Do not connect the left channel of the plug (Vcc) with R001 (200 /ohms) in the second and subsequent units. Use resistors having a tolerance of with 5%. Use of resistors having a poorer tolerance will cause incorrect operation. Never short circuit the left-channel line (Vcc). Doing so will damage the main unit. 2. Operation with Parallel Connections A number of DN-780R units can be simultaneously operated in parallel with 1 button. Operation with parallel connections can be used with a maximum of 5 units. Connection of 6 or more units will lead to indicator operation. 3. Cable Length The longer the length of the cable, the more susceptible the system will be to the effects of external noise. Keep cable lengths to 2 m or less. Do not locate equipment that produces electrical noise in the vicinity of the cable. Doing so might lead to incorrect operation due to the noise. 4. Do not disconnect or connect the remote control plug during operation of the unit. The pins of the plug might cause a short circuit of the pins inside the jack which can stop the operation.

CASSETTE TAPES

2 Handling Precautions C-120 cassette tapes C-120 cassette tapes are not recommended as they use a very thin tape base which may become tangled around the capstan or pinch roller. Tape Slack Before putting a tape into the deck, take up any slack with a pencil or your finger tip. This precaution prevents the tape from becoming entangled around the capstan or pinch roller. 2 Storage Precautions Do not store cassette tapes in a place where they will be subject to: Extremely high temperature or excessive moisture Excessive dust Direct sunlight Magnetic fields (near TV sets or speakers) To eliminate tape slack, store your cassettes in cassette cases with hub stops 2 Accidental Erasure Prevention All cassettes have erasure prevention tabs for each side. To protect valuable recordings from accidental or inadvertent erasure, remove the tab for the appropriate side with a screwdriver or another tool. To record on a tape whose erasure prevention tabs have been removed, cover the tab holes with adhesive tape.

The completion of cycles will always be at the opposite side of the tape in deck B. If the playback deck has been switched, be sure to start playback in the forward direction (1). NOTE : In the relay play mode, it is not possible to perform the play operations simultaneously on Decks A and B. If one of the decks is set to the play mode while the other deck is already in the play mode, playback is performed on the deck that has just been set to the play mode and stops on the other deck. 2 TWIN OUTPUT With the DN-780R, it is possible to play tapes simultaneously on decks A and B and output their signals at the same time. When both decks A and B are played, the signals for deck A are output from the DECK A LINE OUT jacks, and the signals from deck B are output from the DECK B LINE OUT jacks. The DECK B LINE OUT jacks are exclusively for the deck B signals. The DECK A LINE OUT jacks are for both the deck A and deck B signals when deck A line output select switch set to A+B. Use the DECK A LINE OUT jacks when connecting one of the sets of line outputs to a receiver or amplifier.

AUTOMATIC TAPE SELECTION

This Stereo Cassette Deck contains an automatic tape selector which automatically selects the optimum bias and equalization for the tape in use. This is accomplished by detection of the tape type detections holes in the cassette housing. If a tape without tape type detection holes is used, the deck will be set for normal tapes.
y Press the Play ( 0 or 1 ) button !4 to begin playback. The Play ( 0 or 1 ) indicator will light during playback. u Press the Stop ( 2 ) button !4 to stop the playback. If different types of Dolby noise reduction are used for record and playback, playback response will be adversely effected. When power is turned off during tape transport, it may not be possible to remove the cassette by pressing the Eject ( 5 ) button !9. In this case, turn on power again before you press the Eject ( 5 ) button !9.

2 MUSIC SEARCH SYSTEM The music search system detects blank sections (lasting for at least 4 seconds) between selections in order to locate the beginning of selections in the forward or reverse direction. 1. To advance from the current selection to the beginning of the next selection (CUE) : Press the Play ( 1 ) button simultaneously with the Fast Forward ( 7 ) button. Press the Play ( 0 ) button simultaneously with the Rewind ( 6 ) button. The deck will skip the rest of the current selection and automatically resume play from the beginning of the next selection. 2. To repeat playback from the beginning of the current selection (REVIEW) : Press the Play ( 1 ) button simultaneously with the Rewind ( 6 ) button. Press the Play ( 0 ) button simultaneously with the Fast Forward ( 7 ) button. The deck will rewind the tape to the beginning of the current selection and automatically resume play from that point. This is very convenient for repeating playback of the current selection. Notes on Music Search Operation : The search functions operates by detecting comparatively long, blank sections approximately 4 to 5 seconds long, in between recorded selections. Therefore, the system may not operate normally in the following cases: Recordings with discontinuous speech or conversation. Recordings with long periods of pianissimo (softly played music). Blank sections with a high level of noise. Blank sections shorter than 4 seconds. If noise-emitting appliances, such as electric razors, drills, refrigerators, etc., are operated nearby. REVIEW close to the beginning of the program or CUE close to the ending. 2 POWER ON PLAYBACK Playback starts automatically when the power is turned on. Playback is performed according to the reverse mode set when the power was turned off. Playback is performed even if a cassette tape is only loaded in one deck. Playback always starts in the 1 tape travel direction. When tapes are loaded in both Deck A and Deck B, playback starts from Deck A. The power on playback function can be set with the PRESET FUNCTION (page 11).

RECORDING

The operations described below apply to deck A and deck B alike. q Press the POWER switch q to the ON ( ) position. w Load the cassette tape !9, !6. (Check that the erasure prevention tabs of the cassette housing have not been broken off.) e Select the Dolby NR type that suits the recording. r Select the type of tape transport with the REV. MODE button @0. Mode To record on only one side , RELAY or CASCADE Indicator Caution : Be careful not to erase important recordings by mistake. Inadvertent start of recording will happen in the following cases: 1. If the Play ( 0 or 1 ) button is pressed while the 4 indicator lights, recording starts. 2. If the Play ( 0 or 1 ) button and Rec/Rec Mute ( 4 ) button are pressed at the same time, recording starts. The best way to avoid accidental erasure is to break off the two erasure prevention tabs on the cassette housing. 2 PROPER RECORDING LEVEL A too high recording level can saturate the tape and cause distortion. On the other hand, if the recording level is set too low, soft passages will be marked by residual noise. A proper recording level is the most important factor for making well balanced recordings. Guideline for maximum recording level Type I (Normal) Type II (CrO2) Type IV (Metal) +3 dB level on peaks +3 dB level on peaks +3 dB level on peaks

DOLBY B AND C NOISE REDUCTION SYSTEM
2 The Dolby noise reduction system substantially reduces the tape background noise (hiss) inherent in the cassette medium. Dolby B NR is most widely in use. However Dolby C NR is a much more recent development and represents significant improvements over Dolby B NR. 2 Tape background noise consists primarily of high frequency information, which is particularly annoying during soft passages. The Dolby NR system increases the level of low volume midand high-frequency signals during recording and reduces the level of these signals by an identical amount during playback. As a result, the playback signal is identical to the original source, but the level of background noise generated by the tape is greatly reduced. 2 The operating principle of Dolby C NR is similar to that of Dolby B NR except for the encoding /decoding response curves. The noise reduction effect obtained with Dolby C NR is up to 20 dB, compared to 10 dB with Dolby B NR. In addition, Dolby C NR uses an anti-saturation network and spectral skewing circuitry for a significant improvement in the dynamic range of the mid- to high-frequencies.

MAINTENANCE

2 Head cleaning After long usage, tape coating or dust may adhere to the heads, causing deterioration of sound. Therefore, the parts depicted in the illustration should be cleaned regularly. Use a cotton swab moistened with a tape head cleaning solution (such as alcohol). NOTES : 1. Some cleaning cassettes on the market have a strong abrasive effects and may scratch the heads. Always use cotton swabs instead of cleaning cassettes. 2. Since the use of metal tape is apt to collect more dust on the heads, the heads should be cleaned more often to enjoy the best possible sound. 2 Cleaning the Pinch Rollers and Capstans If the pinch rollers or capstans accumulate dust, tape transport may become unstable, as a result from slippage, during recording or playback. The tape can also be damaged if it gets entangled in the capstan. Clean these parts with a cotton swab or a soft cloth moistened with a tape head cleaning solution (such as alcohol). 2 Demagnetizing the Heads The heads will become magnetized after long usage or if strongly magnetized objects are brought near them. The result is a generation of noise, loss of the high frequency range, and in extreme cases erasure of treble components on pre-recorded tapes in combination with added noise. Thus, the heads should be demagnetized at regular intervals. (Head demagnetizers are separately available from your dealer.) 2 How to Demagnetize the Tape Heads 1. Turn off the power. 2. Turn on the demagnetizer while it is at least 30 cm away from the heads. Bring the demagnetizer near the heads and slowly move it in small circles four or five times in front of each head, making sure you do not touch them. 3. Slowly move the demagnetizer away and turn it off when it is at least 30 cm away from the heads.

DOLBY HX-PRO HEADROOM EXTENSION SYSTEM
This deck is equipped with the Dolby HX-PRO headroom extension system. Since the system functions automatically during recording, no switching operation or adjustment is required. The system is effective with any type of Normal, CrO2 and Metal tape. The Dolby HX-PRO headroom extension system functions during recording to raise the saturation level in the treble range. Therefore, most of the treble range components distorted or lost during recording on conventional cassette decks are more faithfully recorded on the new DENON cassette deck. Features of the Dolby HX-PRO Headroom Extension System (1) Performance of Normal and CrO2 tapes can be improved to very close of that offered by Metal tape. (2) The dynamics in the treble range are improved significantly. (3) Since no decoding is necessary during playback, the improved sound can be enjoyed on any type of tape deck, including portable players and car audio systems. (4) The system functions whether the Dolby B/C NR system is engaged or not.

TROUBLESHOOTING

2 SYNCHRONIZED RECORDING

The synchronized recording can be used when the DN-780R is used in combination with other units. Refer to figure 2 on page 10 to connect the equipment. Use a single RCA cable to connect the units EXT. SYNC. OUT jacks with the units EXT. SYNC. IN jacks. Use RCA cables to connect the units THRU jacks wit the units Deck A Line Input jacks. This function can be used when up to 20 units of the DN-780R are connected. Set the infrared remote sensors of all the units to OFF when using this function. Also set the same infrared remote control codes for all the units. (Refer to 3) and 4) under PRESET FUNCTION in the separate operating instructions.) Failure to make these settings could result in malfunction. a Set the first units Master/Slave switch w to MASTER, the other units Master/Slave switches w to SLAVE. s Load the master (source) tape in Deck A of the first (Master) unit. Load unrecorded cassette tapes into all the other (Slave) decks. d Set the units reverse modes. : Recording stops after one side. : For all decks, once recording on side A is completed, recording starts on side B. RELAY or CASCADE : If there is a difference of less than 30 seconds in the time at which the side A tape ends are detected for all the decks, recording starts on side B of all the decks at the same time. Be sure to set all the connected units to the same reverse mode. f Press the TWIN REC button @1 on the first unit. On the first unit (the one set to the master mode), Deck B is set to the recording pause mode and DUB and A+B light. For the units set to the slave mode, both Deck A and Deck B are set to the recording pause mode, A+B lights, and the level meter and Dolby indicator turn off. g Press the DUBBING SPEED button r to select the copying speed. NORMAL : Recording is performed at the normal speed. HIGH : Recording is performed at double the normal speed. h Press the first units Play (0 or 1) button !4 Recording starts on all the connected units. When recording a master tape recorded in Dolby NR, the slave tapes are recorded in the same Dolby NR mode as the master tape. The recording level is the same as the recording level for the master tape. Sound is output during recording, regardless of the copying speed. NOTES: Use tapes of the same times (lengths) as far as possible. Do not operate the Master/Slave switches w during synchronized recording. If a Master/Slave switch w is operated, that unit stops. j Press the Stop (2) button !4 on the first unit to stop recording on all the connected units.
