assistant: Hi Bonnie!  I've been kinda cut off, backbone-wise, for the last month or

And so it came to pass, on 12-24-96 23:07,
   that Bonnie Goodwin spake unto All :
As always though, there are numerous advantages to this transport format as
well.  In most areas, one can always find somewhere to access FidoNet for
free.  Hooking up to another ISP when yours is down or you're out of town is
generally a far more complex matter.
I've checked out the rec.audio.* newsgroups from time to time.  Even used to
port them into the BBS.  The signal-to-noise ratio there is far worse than
you'll ever find on Fido, even when you include the Internet email messages
"accidentally" posted to echoes :)  Far too many losers, whiners, spammers
and just general twits to hold my attention for more than a couple days.
Besides, I have yet to find a newreader that I like as much as my Squish
message-base reader.  Now if I could just pipe my newsgroup feed into Squish
bases... :-)
I'd hate to see the echo move to the internet, and I'm not sure I'd enjoy
seeing it even made available on Usenet, where it can fall prey to the same
lunacy that makes most of the rec.audio.* groups practically unuseable.

Why not just get one of the many 12VDC-120VAC converters available and put a

tend to get pretty expensive, but keep in mind that even in a perfect world
(no losses), your converter will still draw 10 times the current that it
outputs: expect to be upgrading your battery and alternator to match.

Gordon has corrected me: only about 6 feet tall.  In any case, I believe
(it's been a while since I looked) that they are comprised of only the ribbon
driver, and a (relatively small) woofer (one may want to add a subwoofer to
extend the lows).  That's one of the (theoretical) advantages of ribbon
speakers: the extremely light elements reproduce highs
very well, while the sheer size of the moving surface extends the lows quite
well.
Of course, there are always trade-offs.  A near-ideal design for reporoducing
sound, but
they must be extremely large, the ribbons are relatively very fragile,
they're hugely
inefficient, and being an entirely capacitive load, require an amp that can

*LOTS* of current.

UNIQWK meets those needs.  It does bbs olr, as well as internet email and

working at the point unless registered).  It does uucoding as well.  We've
had to use the program to transfer stuff that couldn't be encoded or uucoded
any other way. (Nothing else worked).
As far as the echo, I don't think connecting with an internet usergroup is
the way (because of so many spam(s) and because of the problems with
moderation.)  But the bottom line will be up to Bonnie! <G>

If it's in your price range, consider a four track minidisc recorder. The
four track minidisc format is a year or so old.
If you have a Pentium or P-Pro, e.g., add a Jazz drive and audiophile
sound card or 3, plus software, and have eight, sixteen, or more
tracks, with a range of digital eq, compression, limiting,  & more.
This option also gives 96khz sampling, ensurance for "pro" results.

Write your reply.

assistant: Hi Matt,
 Thanks for your response. Having been subjected to a form of the backbone
being down to me for most of the last three months, due to the hub being
down, the feed being down, the home system being down, the one inbetween
being down, Fido is getting downright frustrating., Then with the move of
many of us off to Internet land, many of whom I'm just now running into and
some of them have lamented not being able to access Fidonet any longer was
the main reasons to consider alternatives for all of us to remain tied
together. Althoguh we have some terrific people in here, we have lost a bunch
for whatever reason, local BBS going down or charging too much for percieved
value, being that it is an "amateur" network, everyone always has a built in
excuse for poor service.
And while I've stated a number of times that *I* don't intend to drop the
echo, it has been effectively done for me for most of the last few months
where I couldn't get access to the echo for weeks at a time .This is BS.
An intolerable situation to an echo junky like me and to some of you who
check here daily to see what's up.
This has led me to consider an alternative connection to the echo through the
Internet, either in a form of a maillist of individual messages, or a
journal, a moderated echo, or some other option that we haven't discussed
yet. Everyone seems to agree that an unmoderated newsgroup would be just more
of the same
stuff.
I'm  taking all of these comments under advisement. Thanks all for
contributing your ideas, comments, etc. to this discussion., It looks like I
may have to set a small BBS back up to do the porting of things back and
forth. I'm invsetigating the software and scripting that will be needed to
get each of these solutions going.
More on this later!

assistant: Hi David!
 How about spending most of the money on a good set of speakers and
upgrade the amp and sources later... That's the way to get the best
sound for the least amount of money, as even a cheap stereo can usually
power a decent set of speakers these days, and speakers are the most
sensitive item in the chain, as they are now the hardest to match to the
environment of your listening space, and are most critical to how good
or how bad your system is going to sound.
 So, if you have a limited ~$2k to invest, spend a lot of time to find
the set of speakers that does it for you and then get a cheaper
integrated or component system to go with it that you can upgrade as you
have funds, and need.
 Think this might be worth looking into? At least it is a way to get up
to the high end stuff some day should you feel you need it. It is
possible to get a very high quality sound from the start by doing things
this way.
Your room could use some looking at and selecting a set of speakers that
will work well with Jimi and with Bach, Handel and the rest might take
some special effort. Please let us know what you decide to purchase. I
would suggest putting about $1500 into the speakers, there are some
truly excellent speakers in that price range.
It seems that the layout of the room is somewhat strange, I would
probably want to put the speakers on the curtained wall side if
possible as that would reduce early reflections and give the rest of the
room a symetricalness that any other way would not have.

Write your reply.

assistant: The thing is that many so-called "analog" advocates seem to think
this problem is a "digital" one.  *ANY* bandwidth limited system, analog OR
digital is going to show some phase shift and harmonic (e.g. square waves)
problems near the upper boundary.  If you put a square wave through a top of
the line cassette deck at 15kHz, you'll get out a noisy sine wave.  A CD will
also put out a sine wave, albeit without the noise.  Don't even bother with
the LP.  The problem is not inherent to digital, but to bandwidth limited
systems.  True representation of a square wave would technically require an
infinite bandwidth, which is highly improbably, and quite possibly impossible
to realize in the real world.  I dare say phase shift is also much less with
the CD than the LP or a cassette and even reel-to-reel tape.  The very BEST
analog recording systems can do better in some areas, but digital can be
improved and has been improved on the professional level.  The consumer
market only needs to catch up.  The question really is, is it even
neccessary?  There are much better ways to improve sound reproduction than
adding more bits and higher sampling rates.  Multi-channel recordings (say
around 8-12 channels) to more accurately reproduce the original soundfield is
one such example.  Properly done with the new DVD medium, the additional
channels could be combined back down to 5 channel, 3 channel, or even mono,
if neccessary, in the digital domain.  One could simply upgrade at will for
better performance.

Write your reply.

assistant: Well, 86dB isn't horrendously inefficient.  Carver's ribbons
are actually one of the more efficient designs due to having one of
the highest gauss fields around in the magnet structure.  I'm told
that if you replace the passive crossover with an active one,
efficiency goes up another 3dB, which is then fairly reasonable.  I'm
not sure about the 10" woofers, though.  That's were I've had some
problems trying to drive them and the ribbons at the same time.  I'm
still not exactly sure what the problem is.  It may be a problem in
the crossover as I've reasoned that if the amp was actually clipping,
the left speaker should "crackle" too since my amp uses one power
supply for both channels.  There must be some sort of feedback or
something going on at high levels.  Meanwhile, I've found they're not
even needed as my sub crosses straight to the ribbons just fine when I
have it set for 90Hz and 18dB above flat (which is where I like it
anyways).
        Where did you get that idea?  Without the passive crossover,
the ribbons are almost totally resistive from what I've been told.
It's the passive crossover that makes it a tough load, although hardly
"entirely capacitive." All the better reason to go fully active,
although that would require having two amps.  Although with the
strange problems I've had, I'd want two anyways if I were going to use
those 10" woofers, given my past problems.

assistant: Hallo Matt
I think it's not a good way to make 120VAC from 12VDC - then transform it to
-for example- 2x40VAC and then rectify it to 2x55VDC (that is what a normal
amp with AC-Input does).
You have 3 voltage conversions with significant power losses.
Additionaly the amps you mentioned are linear ones. That means their
efficiency is max. 60-70%.
When you multiply all those efficienies you get an over all value of hardly
more than 50%.
So your battery has to deliver 400 watts when you need 200 watts on the
output.
My class-D amp has an efficiency of 94% at 200W output power. When we assume
90% (minimum) for the DC-DC converter we get a total efficiency of 85%. This
results in only 235W input-power.
I'm developing switch-mode powersupplies at work and we spend most of our
time in reducing power losses in our designs. So -in time- I have got a deep
aversion to such "oven-constructions" (perhaps not only my person).
many thanks for your reply - Wolfgang
