Re: MD: Minidisc questions (was no subject)
From: "Richard Wright" [EMAIL PROTECTED] Hi Basil, Sorry, but I have a couple of more questions. what is a TOSLINK = connecter/transmitter or reciever? What do they do? Do i need one of = these TOSLINK connectors if I have a sound card that has a RCA digital = output? Do I need a sound card with didigtal outputs to record = digtitally? Also, How can I get my mini disc to play in a car that only = has a CD player? Is there a way that I can connect my mini disc player = to a CD player, and make the music work? Please explain as I am new to = the MIni DIsc World. Thank You. Basil Fakhry. Q: Do I need a sound card with digital outputs to record digitally? A: Well, yes. If you want to record digitally off your PC anyway. If you just want to record CDs digitally, get yourself a CD player with an optical output (eg. Technics 390/490/590 or Yamaha 493. In fact most CD-players seem to have them these days). Richard, are you sure the Technics SL-PG390 has a digital-out? I know the 490 and 590 do [I recommended the 590 to my father as a good starter unit to use with the Sony MD JE520]. I would swear the Richer Sounds mag [a UK cheap hifi chain] said the Tehnics 390 as having no digi-out. Course they could easily have been wrong so don't hold me to that! P.S. UK is 230V +/-5% @ 50Hz - so is the rest of Europe and that's the way it's staying. My multimeter says it's actually 238V at the moment, but that's within the +/-5% tolerance. NOWHERE is moving UP to 250V - that could cause problems with a lot of appliances which are only rated to work at 240V, especially things with heating elements in...that's another topic altogether - probably on alt.electrical.mains.voltages or something :-) I agree Wrighty, my meter varies between about 222 and 244VAC here in England (Northern Electric district). It's accuracy is +/- 1.5% and 5 digits which translates to +/- 10V in the worst case. At present its high, up around 238-242VAC -- am I correct in thinking the suppliers elecricity meters measure current not power so a higher voltage means more power per unit charge measured? On the subject of electric meters, can highly reactive loads (either inductive or capacitave) fool a meter about how much power is being supplied and is this the reason for a clause in the supply agreement, or is it just because its annoying for the electricity supplier?

Yeah, I was in Plymouth yesterday and in the Technics Centre, they had the 390, 490 and 590, all of which said "OPTICAL DIGITAL OUTPUT" on the front. Going by this, I am pretty sure the 390 has an optical digital output. Richer Sounds do get these things wrong sometimes - they say the Yamaha 393 doesn't have one but the Yamaha website says it does - haven't verified this yet... P.S.

I'm not sure about the exact workings of the suppliers electricity meters, so I can't answer that one I'm afraid. On the subject of electric meters, can highly reactive loads (either inductive or capacitave) fool a meter about how much power is being supplied and is this the reason for a clause in the supply agreement, or is it just because its annoying for the electricity supplier? Again, not totally sure. I know a very reactive load can cause problems with things like generators - not sure how they affect electricity meters.

The 390 does have an optical out. A move up to the 490 gives you a headphone socket and remote control though.

Please explain as I am new to = the MIni DIsc World. Thank You. Basil Fakhry. Okay, a few questions there! This may be useful to some other people who are new, so I may as well answer them fully! Let's take them one at a time: Q: What is a TOSLink transmitter/receiver connector? A: This is basically an IC (chip) consisting of an LED (transmitter) or a photodiode (receiver) and a driver, housed in a plastic casing which accepts the TOSLink plugs which you find on the end of optical cables. There are 3 pins sticking out of the bottom which you wire up to +5V 0V (power) and the third is the TTL digital input/output which takes the same format as S/PDIF (co-axial/RCA) except for the fact that it works on 0V/5V (standard TTL digital levels) instead of about +/- 500mV (S/PDIF). Q: What do they do? A: They convert from electrical to optical (transmitter) or optical to electrical (receiver), depending on what's required. Q: Do I need one of these TOSLink connectors if I have a sound card that has an RCA digital output? A: Yes you do if you want to connect to something which only has an optical input (like an MD portable). You will also need a driver circuit to convert the S/PDIF signal (+/- 500mV) to a TTL digital signal (0V/5V). There are boxes around (about 35 to 50 UK pounds) which will do this - I strongly suggest you buy one of these if you aren't electronically minded and have never touched a soldering iron! You could do a lot of damage to several things if you're not careful. Q: Do I need a sound card with digital outputs to record digitally? A: Well, yes. If you want to record digitally off your PC anyway. If you just want to record CDs digitally, get yourself a CD player with an optical output (eg. Technics 390/490/590 or Yamaha 493. In fact most CD-players seem to have them these days). Q: How can I get my MD to play in a car that only has a CD player? Is there a way that I can connect my mini disc player to a CD player, and make the music work? A: Hmm...don't think you can. You can get adaptors which let you connect anything with a line output to a tape machine in a car stereo - these have an ordinary tape head mounted inside an empty tape casing, which just converts the line output from your MD (or whatever) into a magnetic field, which the head in the tape machine picks up, just like reading an ordinary tape. This isn't possible (for obvious reasons, I hope!!) with a CD player. The only way to do it would be if your car CD player has an extra line input on the back somewhere, but I wouldn't go fiddling if you're not sure what you're doing :-) Hope this answers your questions :-) Cheers, Wrighty P.S.
