EuroBirdNet			UK-92-22       1 September 1992

The bank holiday proved to be very quiet apart from Britain's fourth
Ruppell's Warbler (Sylvia ruepelli) which was found at Holme in north-west 
Norfolk yesterday.  It initially hit the grapevine as a Subalpine Warbler 
(S. cantillans) before being reidentified.  

It is a female or immature, and to be honest looks nothing at all like a
Subalp.  Unfortunately is is visible in a restricted mist-net ride,
so viewing is only possible for around 15 people at a time.  It is keeping
to one small area, and showing fairly regularly, so lots of people were
ushered in and out yesterday.  The bird is still present today, so all
those unfortunate enough not to see the bird before dark can have another
go!

I should have also pointed out that the impedance charts are impedance
vs frequency - they go in the lab, squirt frequencies in and measure
the impedance. Meanwhile back at home you are playing music which has
many frequencies - who knows what the impedance is !

My point is that impedance figures are just numbers the manufacturer
conjures up based on some data (data that is arrived at under
conditions you will never have in your home). Its a 'guide' and should
not be taken to be absolute.

If you are matching speakers to an amp, hook them and listen to them
and trust your ears and not some data the manufacturers give you !

A standard response: try "The Loudspeaker Design Cookbook" by Vance Dickason,
available from Audio Amateur Press, Peterborough, NH. It has both the techical
information you need and a fairly comprehensive list of sources.

Date: Sat, 29 Aug 1992 20:28:58 GMT

Having recently developed a hunger for Pro-Logic, I am in need
of new main speakers.  (actually, my first set of decent speakers)

I am new to the speaker department, and need whatever advice can be
given.  Since I will be using these speakers to reproduce pro-logic
movie sound as well as music, I need good response from the deep lows
to the (high?) highs.

From what I have seen, the possibilities include:

	- Satellite/sub systems
	- Full-range speakers
	- Full-range with separate subwoofer

Ideally, I would like a system that brings tears to your eyes (meaning
good bass, among other things!), but unfortunately, cost is an object.

Does anyone have any experience with the dbx all-in-ones from DAK?   That
model _looks_ good--15" subs built in, mid, ribbon tweeter, and one or 
two other drivers.  Then there is the Cambridge SoundWorks Ensemble II
(but those woofers are only 6.x"). 

The Subwoofer from dbx also looks good--15" in its own cabinet (great
price--$150, and I have heard good things from people who have them)

Please post or email--I'll summarize.

Has anyone out there ever heard of "Audible Illusions" equipment?
I have been listening to a Modulus 3D (I think) pre-amp and an
S-120 power amp with a Creek CD-60 CD player over a pair of
Vandersteen 1Bs.  I fell in love with this system from the first

first set-up I listened to.  I intend to listen to a Forte set-up
(F44 pre-amp w/F6 power amp).  Can anyone offer any other

Hey all,
	I'm going to be in the market for a DAT-player and I'm completely
ignorant as to what's up in the market. My experience goes something like this:
I rented a Casio DA-7(Which retails in the neighborhood of $700) to record a
live performance. One of my friends did all the actual dealing with the piece
of equiptment. <end of experience!>
	My main usage would be for home-studio style mastering purposes. I'd
want it to be able to deal with 44.1KHz(and higher if this is a common feature)
so if I were to master CDs from it at a later date, noone would die in a fit
of hysterical laughter.

	My questions to you -- the rec.audio studs:

1) What type of features are important for good sound quality(i.e. error
	correction schemes, oversampling, etc...)?

2) What type of other miscellaneous features should I be looking for for
	home recording(i.e. being able to mark tracks and neato stuff like
	that)?

3) What can I expect to find in the price range of $700 or there abouts?

From what I can tell, the impedance (magnitude) specified by the manufacturer

If the impedance variation is that small, I would say you are doing better
than a lot of commercial manufacturers.  I would probably call it a 4 ohm
speaker.

As an owner of both a Revox B77 Mark II and a Panasonic SV-3900 DAT, I've
had opportunities to do some comparisons between the two.

Each medium has its strengths and weaknesses, but I would say that the
Revox does more than just hold its own when it's properly tweaked for
maximum performance.  Having heard some of the less expensive consumer
DATs, I would have to say that anyone who thinks that a "$600 home DAT"
makes better recordings than *any* analog(ue) deck in the world is not
very experienced with reel-to-reel analog(ue) recorders.

(My comments are based on work with my Revox; that doesn't even get us
into the rarified heights of some of the custom analog(ue) units, such
as those used by engineers like David Wilson, David Manley, James Boyk,
and others.)

Analogue does have its challenges, which are well known, but done properly,
it is a remarkable medium.

So, active cross-over between pre-amp and amp, remove the passive
cross-over in the speakers (somehow); hopefully this is available
in good quality speakers.  

What is a "Zobel" or response compensation network?  I'd guess its
an E.Q. type device to compensate for speaker non-linearities??

A sub is planned for the future.  For now, the speakers I'm planning to
get have a 3dB point of 37 - 21 kHz.  Adequate for a start, but a Velodyne
will be called for in the future! As for your center channel comment,
I've heard this quite often.  I presume this in terms of wattage and
sound quality?  If its under-powered, the voices will not be heard. 
Is this what you mean?

Hi,

I picked up an *old* Bang & Olufsen the other day - a BeoMaster 3000-2.
This receiver doesn't seem to produce balanced output (at least from the
headphone jack). The FM reception was awful (but I was inside a concrete
building) even with its original antenna. 

Anybody has any experience with this receiver? Approx. how old is this 
model? How's the quality? Should I bother trying to clean it up and 
service it? Where can I get the funky speaker connection that this 
receiver uses?

I have a Rotel 855 CD player.  It has two problems.

(1) The right channel is intermittant.  While playing a CD the right
channel might simply go off.  (I have determined that it is the CD player
and not the preamp, amp, speaker, or the wiring.)  Actually the right channel
is not entirely off, it is just much reduced in volume and the sound
is distorted.  Later, usually during a loud passage in the music,
the sound in the right channel may spontaneously be restored to normal.
It might disappear again 10 or 20 minutes later, and so forth.

By the way, the problem can be fixed, at least for a time, by turning
the power to the CD player off and then back on.

(2) The overriding problem now, though, is the fact that it currently
won't play at all.  When you put a CD in and close the drawer, the error
light comes on.  It also comes on when you push PLAY.  (I am not putting
the CD into the drawer upside-down.  Also, I've tried many different CDs.)

Any ideas?

Joe,

Audible Illusions is a small company that produces some very high quality
equipment for the price. I own a Modulus IID preamp (the previous version),
and it is an outstanding piece of equipment. The Modulus 3 is even better.
I bought my IID from a friend who then bought a 3, and his report is that
it is quite a bit better. I would suggest that you listen to some other
combinations as well, but would highly recommend the Modulus 3 and the S-120.
I used this combination when auditioning speakers.
