Tony, talking of DEET, spoke of his reluctance to put "hydrocarbon
derived industrial organic molecules" on his skin.  Toby took him
somewhat to task.

Without ANY intention to flame Tony, I come down a bit more on Toby's
side.  There is a strong tendency in our culture currently to believe
everything artificial/industrial is bad and everything natural is good.
Toby's point (I hope I'm interpreting him right) is that a chemical is 
a chemical is a chemical.  Certainly there are negative aspects to many
products of technology.  On the other hand, plants can make some very 
natural - and very lethal - compounds.  Both natural and industrial 
compounds can rise up to bite us; each should be judged on its effect, 
not its origin. 

This does not mean of course that Tony should slather on the DEET.  His
choice is the conservative approach of avoiding even low levels of risk.
Some folks, however, avoid DEET like the plague but think nothing of
using a mixture of 36 "natural plant oils" to ward off insects.  I
strongly suspect that the long term risks of DEET have been far more
extensively studied that those of that mixture of natural products, and
they are not necessarily safer because they are natural. 

Apologies for the non-bird post.  I'll shut up now.

I can't say that I have hard facts to support my belief, but I think that
DCC, inherently better or not, is going to make a bigger splash in the 
marketplace than MD will.  Being backwards compatible with cassettes is a
big plus to a lot of consumers.

The one thing that I do find really cool about MD, though, is the fact that it
buffers its data before sending it out.

Wasn't Ariston was in trouble about 10 years ago when they were competing
with Linn in the high-end turntable market? I think they changed their

Distribution: rec
Organization: Dept AI, Edinburgh University, Scotland


I hadn't heard of D-type amplifiers before and was intrigued to read
about them on the net and also in a couple of handbooks.

As I understand it, the audio signal is converted into
a high frequency pulse width modulated signal.
When this is fed to a speaker system, since speakers don't move
infinitely fast, out pops the amplfied audio signal again.

Amplification comes from increasing the voltage of the unit pulse
of the PWM signal which can be done with a conventional amplifier
which only needs to be either switched fully one or off by the pulses.

Pros are:

  - it is very energy efficient
  - it should be highly linear

Cons are:

  - radio frequency emmisions are high
  - distortions are introduced by the modulator
  - a low pass filter is needed in the output stage so as not to
    blow the speakers with the high frequency signals in the PWM stream.

Am I right so far?

As far as I understand, most ampifiers (of which there are very few makes) 
have audio inputs and PWM outputs.

Now come some questions:

1) Are conventional speakers used with these amps or are different speaker
   characteristics suggested?
   Like could I use my Mission speakers with such a beast?

2) Can one get a good frequency range from the amp or is it speaker
   depended (more than with a conventional amp)?

These questions aside, doesn't the D-class amp look good for
integration in a digital system?
Instead over converting the digital codes into pulses and then
into an audio signal (as is done in 1 bit players although in varying
schemes) why not take a PWM output from the CD player to the
final stage of a class D amp (the CD player providing the preliminary
stages)?
In this way we would have a digital signal right up until the last
minute where the speaker does the hard bit for us.

Is this possible?

Subject: Switching the Rear Speaker Source
Organization: Corporate Computing & Services
Newsgroups: rec.audio

  I would like to hear some opinions on the following problem. I bought a 
Pioneer VSX 9900s a while back mainly because I needed a new receiver and
thought having one that did Surround-Sound would be fun. I didn't   
realize at the time that during playback of other than Surround type sources
(ie CD, Tape, Radio, etc...) that I couldn't have the rear speakers on 
unless it was using one of the DSP modes. Unfortunately, none of these
modes sound "normal". They all have some delay or other effect different
than the main front speakers. So I disconnected the rear speakers from the 
rear outputs and connected them to the B speaker output. This sounded more 
natural to me and fills the room nicely. What I was thinking of doing is 
to put in a switch that would switch the source for the rear speaker between
the rear source and the B source, and only use the rear source when I 
want Surround mode. Something like this;


             B out --------o \
                              \
                               \o----------- Rear speaker      


          Rear out --------o  


Does this make sense?  I realize that the rear speaker in this arrangement
needs to be able to handle the 125w B output. Also, should I change the 
polarity on the rears, from what the fronts use or should it be the same. 

Any comments are appreciated.

Subject: Lowther (UK) speakers - repair help needed
Organization: AT&T
Date: Fri, 21 Aug 1992 17:43:42 GMT

I have a pair of Lowther Acousta speakers (folded horn design) which I brought
with me the the US some time ago. They have a single drive unit with a paper
cone (actually cones) suspended by a very thin cellular foam material from the
speaker frame. This foam material is begining to fall apart (with unpleasant
sonic results). The drive units are Lowther PM6s. I have several questions:
1 - Is Lowther still in business? Do they have a US distributor?
2 - Does any independant company repair drive units?
3 - Does anyone else make a drive unit with built in tweeter of similar
dimensions (to fit in a ca. 7" diameter hole, 3" deep)?
4 - Am I wasting money trying to fix these beasts, given the advances in
speaker design over the last 15 years?

The last I heard of Lowther was about 10 years ago when they were (I think)
located in Bromley, Kent (UK).

Any help would be much appreciated. Please reply via email if at all possible
as I usually do not get to read this newsgroup.

Subject: Aiwa ADWX-999 or cassette deck advice needed...
Date: 18 Aug 92 08:20:46 GMT


   I'm soon to be in the market for a new cassette deck.  I hope to primarily
use it for mastering demo tapes in my home studio, but don't want to spend too 
much.  A friend of mine got a really great deal on an Aiwa tape deck about
a year ago at an electronics convention... the ADWX-999.  As I recall, from my
brief look at it, it had just about everything (dual record, quick reverse, 
muting, etc...) with good specs.  However, Aiwa didn't have as much success
with it so they discontinued them.  Any suggestions as to mail-order houses
that might have them in stock?  

   Or...

   A couple of other recommendations were also made...  

   One of these recommendations, by model, was the Pioneer CTW-850.  It sounded
good, but I haven't seen one, and I hate to buy without seeing or having a 
reinforced suggestion.

   Another suggestion was that I buy a single 3-head deck.  I don't dub a lot,
but it would come in handy for making multiple copies from one master.  The
question is...is there enough of a difference in sound quality between the more
expensive double cassette decks and single cassette decks.  I have only recorded
with dual cassette decks in the past and have not ben exactly displeased with
their sound, but for demo tapes, maybe better quality is needed.    

   If someone can recommend a better deck than those I've mentioned (IYHO) for
about the $300 range (or if anybody has an AIWA ADWX-999 for sale) please let
me know.  Any advice would be greatly appreciated in saving me from wasting my
money!

Essentially, it refers to products not sold by "Authorized Dealers".  This can
be bad because manufactures' warranties and such often do not apply.  The
warranty you get (if any, you can't be sure unless you check) is only from
the seller, which may be much more difficult to deal with.

I just did a little calculation on these numbers... 100 chips at $5.30 is
$530.  Simple enough.  How many at $11.13 would it take to break even and
go ahead and buy 100 at $5.30?  Only 47.6 chips!  So forget the 50-99
price scale... if you need 48 or more, just buy 100, and you'll spend
less money and have lots of free chips.  At the 25-49 price scale, you can
get 41.9 chips for $530, or 36.9 for $530 at the 1-24 price scale.

So, my point is this:  I'd be willing to buy two of these at any price
lower than $14.36 each.  At $5.30, I'd buy four.  Do we have 22 more people
who would buy a pair of these at $5.30 each?  Sounds like a neat toy to 
have in your junk box for a "one of these days" project, esp. at this price!

Anyone else?

I can also get a good deal on Acoustic Research 707 speakers.  I was told
that they've been advertised at around $800/pair, and I can get them (nearly
new) for $300/pair.  They're three-way speakers. 

By the way, I have a Sony STR-AV770 receiver (80 watts).
