netmduser Posted May 24, 2011 Report Share Posted May 24, 2011 Sony MZ-S1 S2 Sports Net MD I remember reading the manual saying it had a special drive unit. When recording it sounds very quiet but also fast. What headphone circuitry is in this model? Standard Issue? It does sound very clean.

And fw. version? i dont know what firmware version but its made in malasia. it is not broken. it has way too much bass and not enough hi end even with the bass boost off..

Do they have a gold-plated 3.5mm Jack, or the (cheaper) silver-coloured one? Several people have commented that the S1 produces good results. So I wonder what is different in your setup perhaps?

Several people have commented that the S1 produces good results. So I wonder what is different in your setup perhaps? To me, the S1 sounds pretty much identical to others of its kind - that is, Type R Sony portables (I don't think it's Type S) - but I don't like the feel of it. It's just too big and that "one-thumb" joystick you use to get it to Play and so forth doesn't do it at all for me. Maybe I have too many thumbs!

netmduser Posted May 27, 2011 Author Report Share Posted May 27, 2011 Sound may vary from setup to setup - im using mdr-v150s. I don't like the sound from n505, it sounds grainy. The S1 drive is quiet, you can barely here it while is is recording from SS. The fallback is weight. However that is a strength. The metal clasp design appears to take all the impact every time it drops - and it still works afterwards. Quote Link to comment Share on other sites More sharing options...
sfbp Posted May 28, 2011 Report Share Posted May 28, 2011 I don't think it's Type S Actually I think it may be. It's right on the crack of the machines that changed from -R to -S and I think from its date and the chip number, that it postdated the N10 (which is Type-S at least according to minidisc.org).

jim.hoggarth Posted May 28, 2011 Report Share Posted May 28, 2011 Hi all. The S1 uses the same hardware as the N505 and N707. It's not even Type R. And the fault described with the audio is most certainly caused by the same fault that many N505/N707 machines suffer (and R700, G750/755 etc), that is the solder connections to the headphone amplifier IC cracking and requiring resoldering. It can be fixed, so long as the pins are not glued up (I suspect an attempt by Sony to cure the problem, which didn't work), but you need some pretty fine soldering equipment.

Jim my mzn-707 is type r. there is a label on the front. my s1 unit is not type r. the solder connections on the s1 unit are not bad or cracked. the headphones have a gold plated connector the unit just sounds bad... it does have a backlight which is nice.

Yes, you are right. That serves me right for answering at quarter to six in the morning!!! The N707 is Type R, which means so is your S1. They use the same CXD2677-202GA processor, unless you have a rare version not covered by the service manual. Other recorders with this main IC are the N1, R501 and N505. How do you know the soldered joints on the IC are not cracked? It's almost impossible to tell this without some form of magnification. Are you looking at the right chip? The fault has nothing to do with the remote socket connections, although I admit these sometimes get bad joints and bent connections due to the earphone jack plug having pressure placed on it, which moves the socket around in the whole in the bottom case, causing stress on the solder joints to the main board. This is the main stress that causes the fractures in the IC302 solder joints. Jim Quote Link to comment Share on other sites More sharing options...
