7-Pin Interface Cables


Core Sound is pleased to offer the widest range of low cost 7-pin digital audio interface cables. They allow Sony's portable DAT recorders (e.g., TCD-D3, TCD-D7, TCD-D8, TCD-D100 and PCM-M1) to interface to other pro and consumer digital audio devices and to each other. They're a low cost alternative to Sony's high-priced accessory cables, often in short supply here in the US and around the world. Some of our cables offer interface options that are otherwise unavailable.

All Core Sound digital audio cables use the highest quality Teflon-jacketed, impedance controlled coaxial cable. All connectors are soldered using premium high-strength, silver-bearing solder.

All of our 7-pin cables are passive. Passive cables work fine in almost all situations except in a very few situations. (Need to know more about the constraints and limitations of various 7-pin cables in lots of different situations? See our 7-Pin Bible!)

Feel free to call us to discuss your cable needs.


The Sony 7-pin interface uses the S/PDIF data format but its voltage levels are not per the standard. If you need a strict S/PDIF-standard signal, the Sony signals must be converted to the proper levels. We offer our Digital Format Translator and Midiman CO2 format converter for this purpose -- please ask us about them!

7-Pin-To-Coax Cable: Straying from the ideal (i.e., you don't need a strict S/PDIF-standard voltage level), if you want to record from a Sony portable DAT to another device's coax (RCA) inputs, almost all of them will accept the Sony's levels even though they're not per the S/PDIF standard. We've found that Sony DTC-75ES, -59ES, -60ES, -670, -690, PCM-2600, PCM-R500/R300, Tascam DA-20, -P1, -30 Mk II, Panasonic SV-3700 and -3900, Radius Telecast and Audio Media II and III cards (for the PC & Mac computers), Zefiro ZA1 and ZA2 cards (for the PC), Lucid Technologies PCI-24 card (for the Mac and PC), Event Gina, Audio Alchemy DTI Pro32, Audiowerk 8, Terratec EWS64XL, Creative Labs SBLive, Opcode DATport and Sonicport, the DAT-heads DSD, Fairlight CMI3 Digital Sample Card, Yamaha 03D digital mixer, Midiman/M-Audio's Audiophile and DIO, Philips Acoustic Edge, all Turtle Beach cards and our DFT and DPP products all accept it with no problems. So we offer the "7-pin-to-coax" cable at low cost ($45). It works fine with every deck it's been tried with, including between the new Sony TCD-D100 and the Tascam DA-20.

Coax-To-7-Pin Cable: If you want to record from a device with a coax output to your Sony portable, another simple cable: the "Coax-to-7-pin" cable will do the job. It too is $45. This cable will work fine with all modern Tascam decks including the DA-P1, DA-20 and DA-30, most Sony decks including the DTC-59ES, -A7, -R500/-R300 and PCM-2600, the MTU Microsound system, Fairlight CMI3 Digital Sample Card, Lucid Technologies PCI-24 card (for the Mac and PC), Yamaha 03D digital mixer and Roland VS-880 hard disk recorder. It also works fine between the TCD-D100 and the Audio Alchemy DTI Pro32. It works fine between the newer Sony portable DAT decks (PCM-M1 and TCD-D100) and the Opcode DATport/Sonicport, however older Sony portable decks (TCD-D3, -D7 and -D8) will not accept the Opcodes' voltage. There are some devices that do not generate the right voltages for the Sony portable DATs -- these include the oldest Sony DAT decks (e.g., DTC-75ES), Marantz CD players, some Turtle Beach sound cards, the older Creative Labs SBLive card (the newest cards do work!), some Event cards (Layla), E-Mu ESI-4000 turbo sampler, Ensoniq ASR-10 sampler and the Audiomedia III card for the PC computer -- you can use our Midiman CO2 data format converter to mate to these; Sony also makes a cable (the RK-DA10P) that will work with these. The Zefiro ZA2 card will work fine after shorting one resistor on the ZA2 -- contact Zefiro for details. Some Event Gina card work fine. If you have a deck or device that we haven't mentioned please contact us.

7-Pin Combi Cable: The two simple 7-pin/coax cables can be hooked together with a simple coax-jack-to-coax-jack adapter (a "barrel"). This creates a 7-pin-to-7-pin cable assembly identical in function to our TCD-Cable (see a description of the TCD-Cable further on). You can use it to record from one Sony portable DAT machine to another Sony portable DAT. And you can disassemble the cable assembly and use its two cables to interface your Sony portable to other devices. We can provide this very useful assembly for $95.

7-Pin-Coax-I/O Cable: If you need both input and output from your Sony portable, a third cable provides them in a single product. It's a "Y" cable with a 7-pin plug at its base and two RCA coax plugs at its branches. Each branch is three feet long. One coax plug is for input and the other is for output. This cable is called the "7-pin-coax-I/O" cable and is priced at $70. The same limitations hold for it as for the 7-Pin-To-Coax and Coax-To-7-Pin cables. For the Audiomedia III card, you'll need a Midiman CO2 data format converter -- please ask us for details.

TCD-Cable: If you need to connect two Sony Portable DAT machines, Core Sound is pleased to offer the TCD-Cable, a three-foot cable with a 7-pin plug on each end; it allows direct digital connection between two Sony TCD-D3s, TCD-D7s or TCD-D8s. One end is labeled "play/out" and the other "record/in." The "play/out" side is plugged into the playing machine; the "record/in" side is plugged into the recording machine. The TCD-Cable is $65.

7-Pin-to-XLR Cable: We're pleased to introduce a new cable that allows Sony portable DAT machines (TCD-D8, -D7 and -D3) to transfer digital audio to the Fostex D5, Otari DTR-8S, Tascam DA-30, Panasonic SV-3800, T.C. Electronics Finalizer and Sony PCM-2600 via their AES/EBU XLR inputs; it works between the Sony TCD-D100 and the Otari DTR-8S. It also works fine transferring data to an EMU E4X sampler. The Fostex, Sony and Tascam are all smart enough to recognize the Sony's S/PDIF data stream, ignore the the non-standard voltages and even accept Start ID information; they also ignore SCMS. The SV-3800 respects SCMS but does not increase generation counts. We expect to have more information about this cable's suitability for use with other AES/EBU decks soon. The 7-pin-To-XLR cable is priced at $45.

XLR-to-7-Pin cable: We're please to now offer our newest cable, to allow porfessional digital audio devices using the AES/EBU XLR interfaces to send data to Sony's PCM-M1 and TCD-D100 DAT recorders. (This cable will not work older Sony DAT recorders.) We know that it works fine with the StellaDAT, and expect that it will work well with any device using the standard AES/EBU data and physical format. The XLR-to-7-Pin cable is priced at $45.

All of our cables come with right angle 7-pin-plugs.


Our cables can be used to "daisychain" between Sony portable DAT machines (other brands too). For example, if you were dubbing from a DAT deck and someone else wanted to dub from you at the same time, you'd use a daisychain. And if someone was recording using microphones at a concert and you wanted to take a digital feed from him and pass it on to another taper, you'd again use a daisychain.

The daisychain would look like this:

The first DAT machine would use a 7-Pin-to-Coax cable to output its digital data stream. The second machine would use a 7-Pin-Coax-I/O cable. A simple RCA-coax-to-RCA-coax barrel would connect the first cable to the input side of the second cable. The third DAT deck could also use a 7-Pin-Coax-I/O cable and hook up the same way as the second deck. The last deck in the chain could use either a 7-Pin-Coax-I/O cable or a Coax-to-7-Pin cable.

If you were dubbing a tape that had SCMS limitations, an SCMS stripper could be inserted anywhere in the daisychain.


When connecting cables to Sony Portable DAT machines, be sure that the power is off.

The Sony 7-pin jack has a channel that surrounds the 7 sockets. Be sure that the cable's pins are not accidentally seated in the channel rather than in their sockets.

G.A.S., in Italy, wrote: I received the [7-Pin-Coax I/O] cable yesterday. Works fine, including with my "vintage" Revox B226 CD player and an inexpensive coaxial to optical converter. A very good alternative to the overpriced Sony cables !
