With these adaptors, you can use your European R55 over in the States because the mains voltage goes up to the transformer then is brought down to the useable voltage for the appliance.

Re: MD: Portable power pack
One caveat though, make sure the voltage and polarity are correct each time you plug it into the recorder or you can destroy the recorder. That holds true with any universal power adaptor. I remember seeing a small calculator being made into a paper weight because of a universal power adaptor. The guy had it set correctly, but the plug became disconnected and someone else so it was disconnected and plugged it in the wrong way.

Re: MD: Compression on Sharp-831
* Dale Greer [EMAIL PROTECTED] on Fri, 05 May 2000 | Simon, this is one of the funniest things I have read in a long time. Thanks | for the wit Hey, at least both Ralph and I agreed on something ;). But it is not so much as the headphones causing hiss but seeming to cause hiss when what they are really doing is amplifying "peaky" high-frequency noise that would be inaudible with different/better headphones. The significant difference between Sony ATRAC and Sharp ATRAC is that Sharp tends to have better high-frequency response where Sony has better low- frequency response. If there is high-frequency noise in the original signal, the combination of Sharp ATRAC and hissy headphones could conceivably amplify it. -- Rat [EMAIL PROTECTED]\ Warning: pregnant women, the elderly, and Minion of Nathan - Nathan says Hi! \ children under 10 should avoid prolonged PGP Key: at a key server near you! \ exposure to Happy Fun Ball. - To stop getting this list send a message containing just the word "unsubscribe" to [EMAIL PROTECTED]
Re: MD: Compression on Sharp-831
Luke, Yeah, analog soundcards on laptops can be REALLY bad depending on how well they isolated the analog circuitry from the digital circuitry. I've got a Gateway solo 9300 (or something like that) and it has an optical SPDIF connector (rectangular). I found a standard optical cable which directly plugs into both connectors.

MD: digital recording between sony discman d-ej715 and sony md mz-r70
i have been digitally recording onto my sony mz-r70 from a sony discman, model d-ej715. this is my first digital recording experience. i expected very crisp recording with no static or distortion. however, on a duplication of the 'Third Eye Blind - Blue' cd there are many points where static is clearly noticable. i use a sony optical cable (poc-15b), sony blanks, and i have even tried re-recording. the distortion still exists in the same spots. do i need to manually lower the recording level? or could this be limitations of the ATRAC the mz-r70 uses? would it help to use higher quality media like the ceramic sony discs? please help! - billy hetherington Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com - To stop getting this list send a message containing just the word "unsubscribe" to [EMAIL PROTECTED]
MD: Bad Ebay seller alert: BECKHAMDEE
Hello people, Some of you may know me as the guy who wrote the Sharp 831/Sony MZR90 review page (URL: http://www.ece.utexas.edu/~youn/r908331.html). Well, I've recently had a bad eBay experience with a dishonest seller, and naturally, I feel obliged to alert others. EBAY user ID: "BECKHAMDEE" ([EMAIL PROTECTED]) "Real" name: Wing-Yip Yim --Works out of Brooklyn, New York-- The subject was selling a BLUE Sony MZ-R50 (vintage and pretty rare) on eBay, which was listed as being in "used, very good condition, very infrequently used." Well, having spent the better part of a year searching for a blue R50, I bid on the item and ended up winning, paying over $250 for the item (in retrospect, that was probably a bit much). Of course I took the time to email him to verify that the unit was in good condition, and that there was nothing wrong with it, to which he replied that it was in "used but very good condition", as listed. When I received the unit, it had: --a large dent on the top face; --there were 3 screws missing and the clamshell lid was VERY loose on the top-left corner; --the laser was misaligned, as it has trouble reading discs correctly (the laser tries to read the same part of the disc over and over, getting "lost" and stalling during playback). While the unit did playback fine if I turned it UPSIDE-DOWN, I tried editing a few discs, and it ended up corrupting two of my discs (gave a DISC ERR message), thus I ended up having to delete the discs and rerecord them from scratch. To make the rest of this long story short, the seller initially offered a full refund. However AFTER I sent the unit back to him, he changed his mind and refused to return my money, claiming that I must have damaged the unit MYSELF, claiming it was working perfectly and didn't have any loose screws when he sent it to me. The seller has since sent back the item to me, keeping the money, and refuses to reply to emails. Of course I have left him the appropriate negative feedback mark, as that is all I can realistically do, but as he has about 6 or 7 other positive feedbacks (apallingly!) which "dilute" the negative mark, it doesn't really do that much. Plus he still has the money, and no negative feedback will help get that back. If this isn't your classic example of dumping off a busted item to a sucker and running with the money, I don't know what is. The subject continues to do business on eBay (selling things other than just MD equipment), and I would advise anyone to deal with him with caution. While he seemed very polite initially thru emails, it seems obvious to me that he pulled a quick one--and unfortunately, got away with it. Anyway, this sort of stuff happens, so please be careful. I am posting this to the forums that I feel appropriate; if you feel this is an inappropriate posting, my apologies.

MD: Psycho-Acoustics OT
Greetings folks, I was just playing around in Cool Edit, and I discovered a pretty crazy little are that did "Brainwave Synchronization" and some other random crazy things. I have a little experience in thse matters, but I am looking for some good webpages and source material on the topics of Brainwaves and music, rays of different variety (Gamma, Theta,) etc... I figure, if there's one place where they'll be a bunch of people who know random musical information of a technical nature, and so here I am... Thoughts, suggestions? I know that I wrote OT, but there is an On Topic (OT?) :) reference as well. Minidisk recorders and the ATRAC compression system eliminate a large portion of the audio from a signal, and we have all been told that this missing signal not in the human hearing spectrum. Now many of these special areas of sound are in the extreme ranges of frequency, and I can't imagine that the ATRAC and other compressions do not remove/alter the effect of many types of music.

Re: MD: Li-Ion batteries
Hi, There's no gumstick-sized Li-ion batteries at the moment. A while ago I did some research on polymer Li-ion batteries, now often used on new cell phones. What I found was that the cell phone batteries are at least the size of two gumsticks lined up side by side, yet their spec is identical/smaller to Sharp's non-polymer Li-ion batteries (3.6V, 600mAH). If the material doesn't have higher energy density than they are now, a gum-sized polymer Li-ion battery wouldn't necessarily hold out longer than a Ni-MH. I could be wrong... actually I wish I'm wrong, because I'd like to see the advantage of polymer Li-ion do something good for the portables. :) Leon Does anyone know if Sony make 'gumstick' Lithium Batteries for their portable recorders, specifically the MZ-R90?

Re: MD: Psycho-Acoustics OT
Before I begin: anything that really ever doubts MD is less than what the research papers say it is gets lots of flame on here. But anyway. Supposedly, louder sounds "eclipse" much of the quiet sounds, so the data of those quiet sounds can be omitted. Psycho-acoustics also takes the sensitivity of the ears into consideration. The two together would seem like a lot of "savings". Some of the supposed "advancements" commercialized by the companies: Sharp ATRAC 6 - mostly same as 5, but the encoding algorithm is variable according to time, frequency, and loudness (not sure if it's loudness). Sony Type-R - double computation power, supposedly leading to better realization of the algorithm; Matsushita H.D.E.S. - Emphasis on low and high frequencies, which in a way goes against the original ATRAC principles. Adapts to cut down pre-echo noise (noise that may occur when level suddenly goes up). Pioneer ARTIST-SYSTEM - DSP creates masking database on the spot and sends it to ATRAC to determine what will be encoded. All these newer ATRAC algorithms seem to have been designed, so that the highest frequency band (15-22kHz) is represented as much as possible (Sony 4.5 was improving from 4 in this aspect). Traditionally, since the ear isn't that sensitive to these frequencies, this is one of the least emphasized band for encoding. Yet maybe it's true that more-than-natural emphasis on low and high frequencies would sound more pleasant to the ear? It seems that other key to good encoding is speedy computing. The article about Sony version 3.5 on MDCP had the developers mention something about that, I think it's about the 3.5 chips being able to do floating-point calculations. There's definitely this factor in Sony going from 4.5 to type-R. From what little knowledge I have, it seems that ATRAC is more than capable of representing all genres of music with ease. But maybe ultimately moving just slightly away from the basic principles give more pleasant results. Just maybe. Leon I know that I wrote OT, but there is an On Topic (OT?) :) reference as well.
