Features: First ATRAC ``Type-S'' machine. NetMD and MDLP support. PS/2 keyboard input. Gold plated connectors. Torroidal R-Core transformer. Colors: Black and Silver. Only available in Europe?

ATRAC Type-S: "Type-S" apparently refers to a new chip containing an improved version of the ATRAC3 codec as well as the ATRAC1 Type-R codec; the combination of the two is called DSP Type-S. From Sony's information sheet: "The two new products MDS-JB980 and MDS-JE780 in the press announcement at CeBIT both adopt the newly developed DSP (Digital Signal Processing) IC chip "CXD2664R." The CXD2664R chip has two DSP functions; one is ATRAC DSP and the other is ATRAC3 DSP. The ATRAC DSP, the TYPE-R algorithm which is the version of the highest grade, is adopted, and the highest sound quality can be obtained at the time of recording. And the ATRAC3 DSP, the algorithm of a newly developed DSP is adopted. It can reproduce the track recorded in MDLP mode in very high sound quality at the time of reproduction. This works in the same way for the disc recorded by other MDLP products. Sony calls the DSP functions of the CXD2664R chip "ATRAC/ATRAC3 DSP TYPE-S". In other words, "ATRAC/ATRAC3 DSP TYPE-S" is a combination of "ATRAC DSP (TYPE-R highest Version)" and "ATRAC3 DSP (newly developed)."

Features: Very similar to MDS-JE530 (below), but adds PS/2 keyboard connector (for titling), and CD-TEXT capability (via S-link).

Tips:
(Courtesy Mitch P.) Many useful functions are available through the keyboard interface, e.g.:

• Use the / (backslash) key on the keyboard to divide the track and get a track mark. This nice feature also allows you to preview your "division" before actually doing so.
• Push the - (minus) key on the keyboard to delete a track.
• Pushing the "cntrl" and "enter" keys on the keyboard instantly puts the JE630 in synchro-record mode.

Features: Cost reduced version of MDS-JE510. Compared to the JE510, it lacks a headphone jack, mono-recording mode, date and time stamp recording, digital optical output and the wireless remote (though front panel IR port is still present so a remote may be purchased separately). Unit is sold in Sony MD BUNDLE 5. Understood to work with RM-D10P/D20P remote. TOC cloning not possible (machine ejects disc when power applied).

Features: ATRAC 4.5 (IC: CXD2654R), digital recording level control (with fade in and fade out), 6 second time machine recording. Hybrid pulse DAC, 20 bit delta-sigma ADC. Two-line text display on front panel provides increased track and title information over previous Sony decks. Larger level meters than previous JE5x0 units. 15 element music calendar (vs. 25 in previous JE5x0 units). Editing can be performed from the remote (not possible with previous JE5x0 units). User settable LEVEL SYNC threshold (i.e. silence threshold for track-marking). TOC Cloning possible. Remote: RM-D15M. MDS-S39 version (mini-compo variant) can be controlled with a GUI interface from a PC or Mac with the PCLK-MD1 connection kit and software (¥15,000). Unit does not spin the disc in record-pause mode (as the JE500 and JE510 do).

Components: MD mechanism type: MDM-5A, Optical pickup type: KMS-260A/J1N

Notes: The JE520 has several built-in odometers (total play hours, total recording hours, total errors, etc.), see page 3 of the service manual.

Minor Glitch: If you play-pause unit and edit track name, character '!' selects A point for A-B repeat mode. This only occurs in play-pause mode (very minor problem).

Tips:

1. While in the mode for setting the Rec Level ( any input kind ) one can press and hold the "yes" button while turning the JOG wheel to inc./dec. by 1 dB instead of 0,1 dB.
2. Playing a track one can press the letter "D" button on the remote control to se if there is any time and date stamp on the track.

Comparison: The JE520 and JB920 both have: digital record level control, 2 optical digital inputs (1 optical digital output), timer standby recording, advanced timeshift recording (6 second time machine), 20-bit A-to-D Converter (520 = hybrid pulse, 920 = current pulse), off-center insulator feet. The JB920 alone has: pitch control, coaxial digital input and output, date/time stamp, anti-resonant aluminum front panel, R-core power transformer, S-Link interface to Sony A/V equipment: CD Text and Custom File transfer, Rec-It ("the amazing remote control convenience that enables one-button recording of whatever CD track is currently playing"). -Gary Milliken

Features: Jog thumbwheel on unit is reminiscent of the MZ-R30 and MZ-R50 portables. When the included ``MD Editor'' program is installed on a Windows '95 PC or Mac running Kanjitalk 7.1, the computer can be connected to the MD deck and the deck operated via mouse input to a GUI based control program. With this program, titling can be done in Kanji and Hiragana (JIS1&2) to MD sector 4 (vs. MD sector 1 for Roman and Katakana titles), but the deck can only display Roman and Katakana titles. When coupled to a CD player with an A1 control port (e.g. Sony CDP-CX200F, Sony CDP-CE515), program editing can be accomplished via simple drag and drop opertion. Wide bit stream block floating calculation gives 20 bit accuracy dynamic range. Sampling rate converter, 6 second time machine. Usual TOC editing functions plus A-B erase. Included with the PC1 is the PC link kit (PC connection cable, application software CD-ROM) and wireless remote. The PC connection cable converts RS232C to a Sony A1 (S-Link) control signal and is part number CAV-50C. ATRAC 4.5. Unit is the same as the MDS-JB920 internally.

Features: ATRAC 4.5 (IC: CXD2537R). Very similar to Sony MDS-JA50ES (below), with these differences: 1) 20 bit delta-sigma A/D (vs. 24 bit in JA50ES), 2) includes newly developed S-TACT IC pulse generation section [for DAC], reducing digital and analog noise, 3) has only one R-core transformer (vs. 2 in the JA50ES). Remote: RM-D14M

Links: Sony's Japanese Page for the unit. Sony Deutschland's JA30ES page. A user's review of the Sony MDS-JA30ES.

User comments: In comparison to the JA50ES, the '50 seems to have far better construction and power supply. As a result, it has slightly better numbers in dynamic range (105dB vs 104dB) and S/N ratio (108dB vs 107dB). These numbers are for playing back, so the difference in A/D converters has no effect. Notice that JA50ES is really heavy (14.3kg vs 9.3kg for the '30). If you look and touch these units, you can feel the difference of materials.

Specs: Dynamic range: 104dB. S/N (manual: >104dB, brochure: >107dB, German Stereo magazine: >112dB). Freq. resp: 5-20kHz +/-0.3dB. THD: brochure: <.002%, German Stereo magazine: <.0012/.0013 (L/R). Line in: 47 kOhm, 500mV rms (min: 125mV rms). Coax in: .5Vp-p +/-20%, 75 Ohms. Optical in: 660nm. Line out: 2Vrms@50 KOhms, impedence: 10 KOhms. Digital out: -18dBm, 660nm. Phones: 28mW, 32 Ohms.

Features: Essentially the same as an MDS-JE500 (circuit board, A/D/A chip, ATRAC chip, main ASIC, user manual, feet, all identical). Some units made in Malaysia. European/Japanese unit (see below) adds A-B erase. TOC cloning not possible (machine ejects disc when power applied).

Components: MD mechanism type: MDM-3A/3B, Optical pickup type: KMS-260A/J1N

Variants: Information in the service manuals indicate that there are at least two JE510 models, the AEP, UK, and German ``European'' model (with coax input) and the US, Canadian and E ``North American'' model (lacking coax input). The NA model contains the same mainboard, BD board, HP board, optical pick-up and drive mechanism as the JE500. The European model has a different mainboard layout to carry the coaxial input and a few more capacitors in its analog section. The coax input adds a connector, three resistors and one capacitor, but no new ICs. The principal difference is that the NA model has the CXD2650R chip while the European model has the CXD2652AR instead. The latter can control an external DRAM chip, in this case IC124 -- a 4Mbit dram memory buffer, giving a total of 6Mbit DRAM when the internal 2Mbit DRAM of the CXD2652AR is included, this allows the 6 second time machine function on the European and Japanese versions. Incidentally, the CXD2652AR with 4Mbit external DRAM memory is used in the MZ-R30. The CXD2650R and the CXD2652AR chips are both ATRAC 4.0. -Dirk ([email protected])

The MDS-JE510 sold in Japan has a 6 second time machine, 2 optical inputs (but no coax input), A-B repeat and A-B erase functions. The RM-D10P remote titler allows Katakana entry on US model.

Problems: Several users have reported a problem wherein the unit will switch itself on automatically. The cause is thought to be a failure in the disc insertion sensor microswitch. (Part Number: 176262121, Description: Switch, Push) The problem seems not to occur if a disc is left in the machine, although when this is done there have been occasional reports of the unit then behaving as if no disc were in the machine and refusing to eject it. Ethan Straffin has made a page for reporting and viewing the Sony MDS-JE510's self turn-on problems. Joe Redifer has made a page describing how to shim the microswitch to alleviate the problem. Chris Stanley and others report their success with Redifer's self turn-on fix for the Sony MDS-JE510 (and that it also works for the Sony MDS-S38).

Features: ES deck functions in a mid-range priced deck. ATRAC 4.5. Variable pitch and speed control, range: -95% (!) to +12.5% (Sony US announcement says variable pitch, Sony Italia announcement says variable speed, apparently it varies both at the same time, as if varying the motor speed with tape or vinyl). Digital Record Level Control for recording and playback. A-B delete. User settable LEVEL SYNC threshold (i.e. silence threshold for track-marking). Two-Line front panel display. CD Text and Custom File Transfer automatically records and displays disc and track information when recording from CD to MD. R-Core Power Transformer, 20-Bit Analog-to-Digital Converter, Current Pulse Digital-to-Analog converter and Anti-resonant Aluminum Front Panel. 6 second time machine recording. S-Link circuitry allows operation with other S-link equipped Sony A/V products Can be controlled with a GUI interface from a PC or Mac with the PCLK-MD1 connection kit and software (¥15,000). RM-D17 remote (equipped with EDIT/NO and YES buttons). Date and time stamp recording. Unit does not spin the disc in record-pause mode (as the JE500 and JE510 do). Unit is the same as the MDS-PC1 internally. TOC Cloning possible.

Components: MD mechanism type: MDM-5A, Optical pickup type: KMS-260A/J1N

User comments: Digital and Analog REC LEVEL are separate. There is a built-in FADER that can be used for recording AND playback. Disc loading is much faster and much quieter than the JE500 (about like the old MDS-501) and the disc is pulled in much sooner than on the JE500. Editing is more complicated due to the menuing system. Super Undo also works. An automatic demo mode pops up when the deck has been on for 10 minutes with no disc. There are two pitch controls, regular and fine. Pitch controls are slow and aren't useful during playback because every time the pitch is changed, the sound cuts out while the machine recalculates or does whatever processing it needs to do to change the pitch. It is able to do it about once a second, so it is easy to turn the pitch control faster than the JB920 can keep up. It's definitely useless for DJ effects where a smooth change in pitch is required. Text scrolling is much faster than the JE500. Track calendar is much smaller than the JE500 (only goes to 15 tracks). VU meter is longer than the JE500. The 2-line simultaneous text and track/time display is very nice. The procedure for getting into Test Mode works. Digital In and Digital Out can be set to 16, 20 or 24 (!) bits. Analog LINE-OUT output level can be electronically adjusted. -Shawn Lin

Mis-features: Does not show running date and time stamp information during disc playback (shows static track date and time stamp info), normal track time (and track remaining time) increments (decrements) properly however.

Problems: The disc drive mechanism has been shown to be finicky when loading discs, however Sony knows about the problem (an internal technical information bulletin has been published to SONY Service centers).

Service Manuals: MDS-JB920, MDS-JB920, supplement 1, MDS-JB920

Features: ATRAC 4.5. Provides 2 independent MD drives that allow recording to one MD while editing another, or recording from two different sources simultaneously. Seemless (uninterrupted) playback and recording from one drive to the next. Unusual "Inter Disc Move" function will move a song from one disc to another at 4 times realtime, defragmenting the copy and deleting the original. The move is done losslessly in the digital domain with raw ATRAC data. Sampling rate converter. Digital recording level control (-inf to +12dB). Large, 140 x 40 dot matrix display shows graphic information to simplify editing. Wide Bit Stream (uses block floating calculations to create an effective 20bit dynamic range). Includes built in timer that can control its AC outlet for connecting a tuner, etc. RM-D22M remote.

Links: Sony's Japanese announcement of the unit, and its English translation.

Components: MD mechanism type: MDM-5B (similar to MDS-JE520), Optical pickup type: KMS-260A/J1N

Specs: S/N > 98dB (playback).

User comments: Think of this machine as two independent MD decks. Each MD drive has a complete set of controls, including AMS knob and buttons for edit/yes, display mode, source select, etc. The large (140 x 40) dot matrix display allows a small "GUI"-like interface that's reasonably well laid out and straightforward to read and use. All buttons and messages in English (manual was Japanese however). Regarding inter-disc move: Inter-disc move runs at 4 times realtime (a 60 minute disc can be moved in 15 minutes). There are two move modes, "whole disc" and "single track". Whole disc mode moves all the tracks from one disc only onto a blank disc, defragmenting while moving. Single track mode moves a single track onto the end of the target disc, defragmenting while moving. The normal input sources available for each drive are: optical #1, optical #2, coax, analog, analog from other drive and digital from other drive (in this case digital means S/PDIF, observing SCMS limitations). Unit has pitch control (you must enter a menu to adjust it) and line out level control. Can do "relay" recording; if set, when recording comes within 10 minutes of the end of one disc it starts recording on the next one.

Simon Mackay asked:

Is it possible to play material on Deck A on the MDS-W1 out to a device such as a mixer while recording the results of the mix (with the material on Deck A) from the mixer's tape-recording bus on Deck B? This is so that a backing track on Deck A could be recorded on Deck B with the vocals derived from the mikes attached to the mixer.

Yes, but it isn't easy. The problem is that only one deck can have the outputs at a time; as soon as deck B begins recording it will grab the outputs and the mixer will no longer be receiving the material from deck A. You could start deck B recording silence (don't try to use Music Sync) a moment before, so that deck A will grab the outputs when you start it playing; or you could start some dummy noise coming out of the mixer (whether it comes from deck A or from one of the mixer's other sources), let deck B grab the outputs, and then either start playing deck A for it to grab the outputs or press the OUTPUT toggle to give them to deck A.

The usual way for recording from one deck to the other is over one of the internal buses; fighting over the outputs is the major stumbling block in the way of recording from one deck to the other over a cable.

User Manual: MDS-W1

Service Manual: MDS-W1

Features: Appears physically identical to Japanese MDS-JA22ES model, similarly containing same "Type-R" DSP for ATRAC (IC: CXD2654R), Wide Bit Stream feature for 20 bit accuracy, tray loading, digital record level control and "R-Core" transformer. Unit has frame & beam construction, aluminum front panel, double thickness top plate, variable coefficient digital filter, 20 bit A/D converter, current pulse D/A converter, wide range pitch control, jog dial, remote, automatic cd text and custom file disc and track name transfer from compatible Sony CD players, digital output bit length selector (16, 20 or 24 bits), advanced time shift recording (time machine), S-link interface, two line text display, expanded fluorescent meter (like JE520), 15 element music calendar, time and date stamp. Unit allows mono recording mode. RM-D19M remote.

User comments: Does not have the MDS-JA22ES GUI interface. Remote commander features "menu/no" & "yes" keys, a "D.O Bit" digital output bit length selector key, "recorded" & "present" date keys & a unique and handy "Rec-It" key. Utilizing this feature requires that a "CONTROL A1" cable is connected (from MD) to a "CONTROL A1" compatible Sony CD player. When playing a CD from the A1 connected CD player, you can press the "REC-IT" button during a track you wish to record. This returns the CD player to the start of that track and recording commences. When the track ends, the MD deck stops recording and CD playback continues on to the next track as usual.

Features: 24bit delta-sigma A/D. Current pulse DAC (same as JE700). ATRAC 4.5 (IC: CXD2537R) with new ``adaptive high frequency control technology'', 11.6ms edit point accuracy.

Adjustable recording level control for both digital and analog inputs. Non-clip function in digital recording mode automatically reduces recording gain to avoid clipping (can be disabled). Selectable fade-in and fade-out of digital inputs during recording. Fade in and out curves can be separately set to follow a linear, sin, or log curve. Fade in and out times can be set separately between 1 and 15 seconds. Digital level control has 3 settings: off, recording use only, recording and playback use.

Various track mark functions: off, auto (level based), as well as 1 minute and 5 minute intervals. Auto track mark silence detection level can be set from -72dB to -0dB in 2dB steps. Auto track mark minimum silence duration can be set from 0 to 9.5 seconds in 0.5 second steps.

Has selectable resume function modes: 1) disabled 2) starts play where it left off (just like the portables), or 3) starts play at next song, even after power off. During playback auto space (insert space when crossing tracks) or auto pause (enter pause when crossing tracks) can be set, or disabled. Peak hold function, works during recording or playback. Digital output filter has 4 settings to control rolloff of frequencies above 20kHz to better suit system, room or song acoustics (adopted from Sony ES CD player). 6 second time machine. Digital out word length can be set to 16 or 20 bits, when connected to another 20 bit machine or D/A converter can do 20 bit dubbing. Handy indicator LEDs on the play, pause and record buttons.

Comments: from German Stereo Magazine, 10/96:

• The slight improvements in coding complex music weren't audible to the testers (and ATRAC 3.5 already scored well against DAT).
• Sounds very good (transparent sound, no coloration).
• Very low noise DA converter, even with small signals (approx. the level of DAT DTC 790, a little bit better than the MDS-503).
• At normal record levels the AD converter is very quiet too.
• At small analog signal levels has more noise than the '503 and noticablely more than DTC 790.
• The converters are far from Sony's claim of 20 bit resolution, the 18 bit converters of the JA3 were much better ("a few grades"). The reason for this seems to be the bundling of ADC / DAC into one chip, whereas the JA3ES has separate AD and DA chips.
• For most users completly satisfying (esp. for this price 600,-DM)
• Music-synchro feature (works with any digital input): starts recorder if the SPDIF input has a signal above -60 dB
• UNDO function
• New slot in mechanism
• Freq. response up to 18kHz
• Evaluation: excellent ***

Variants: Different versions existed for the JE-500.
Part numbers (taken from the service manual):

• 4-983-660-1: US model

There are at least two different versions of the MDS-JE500: `older ones' and `newer ones'. The differences are a few changed values of capacitors and resistors in its analog section ([email protected]).

Differences: between JE500 and S37: JE500: Headphone and analog phono input and output connectors are gold plated. 1/4" headphone jack.
S37: Audio bus connector. RM-D10P titler cannot be used when audio bus is connected. Miniplug headphone jack. No timer recording function, timer recording can only be done when connected to Pixy system with audio bus. Audio bus connection is not required for normal operation.

Problems:

• It appears there may be a firmware problem on the early machines that happens mostly (perhaps only) just after you start titling while recording. A "Retry" and "Retry Error" can sometimes appear on the display while recording. The "Retry Error" one (more severe) can cause a problem such as a drop out. To experiment: soon after a song starts recording, hit "name" on the remote and start entering a title. One user got the error a couple of times upon first hitting a letter key. Workaround: enter titles after waiting at least 10 sec. after pushing RECORD.
• If you stop recording DIRECTLY after a song, then it will cut off a 1/2 second of your song. Probably the record buffer is not fully written when the STOP key is pressed. Workaround: Press PAUSE, wait and then press STOP.
