Write your reply.

assistant: Ref: Glass and listening areas.
Hello Phil,     My home has what we call a "sliding glass" patio door. The
was an invention of some really twisted mind in the late 1950s that makes it
impossible to seal a home from the elements, often jumps the tracks and won't
close or will stick one time you close it and slam the next time. It consists
of two glass panels approximately two meters in height and one meter wide
(each). One panel is stationary while the other slides from side to side on a
track. They were popular because they do not swing in abd take up wall space,
thereby allowing more efficient use of your floor space.
        Dual and triple pane glass is often used, increasing the insulation
factor, but adding to the weight and difficulty in maintaining the seal
around the door when closed.
        They are horrible for sound reflections! The sound comes off the
glass much faster than it does the surrounding wall materials. Covered with
panels or heavy draperies, the glass panels will easily begin vibrating when
hit with anything near a well reproduced bass note. So they require constant
adjustment or "packing" which makes they harder to open and close.
        Nope, sliding glass doors are something you want to stay away from at
all costs.
Cheers, John

user: You are replying to Dennis Jenkins about "Hafler Model 500 Amp".

Write your reply.

assistant: Hello Dennis,
        Yes, I can happily report that I have replaced my twin Carver TFM-35s
in my main stereo channels with the old Hafler Model 500 I bought at the
garage sale, and couldn't be happier!
        To be fair though, I must say that I replaced my old standard issue
Monster Cable speaker wires and my Carver Pre-Amp Tuner with the new Carver
Pre-amp/Tuner all at the same time so I cannot say what changed what, except
the speaker cables. Those I installed first and tested against a couple
others in a rather unscientific test (but enough to more than convince me
that there was a difference).
        I tried four pre-amp/Tuners and ended up buying another Carver. I
wanted to get an on-board Pro Logic processor and eleminate the video
switching unit (JVC) the old Carver required. My fear was that in going to an
onboard Pro Logic unit I would loose the musicality of the old Carver, which
Carver does a first rate job of. Sure enough. The others I tried did an
exceptional job of Home Theater, but not so good with straight up 2 channel
stereo music....my first love. I couldn't afford a Lexicon or anything in
that price range, so I ended up bringing home another Carver....and love it.
I will miss the Sonic Hologram feature, as the new unit doesn't have it. But
I am trying to find an external unit via the Internet now.
        The Hafler is just simply amazing! It has all the power anyone could
want and then some. My concern about the fan being to noisey was completely
unfounded and it is very efficient in cooling the unit...even in heavy use.
What is wrong with yours? Is there somewhere locally you can have it
epaired?
How long have you had it?
Cheers, John

assistant: And so it came to pass, on 03-17-97 21:22,
   that Kenneth Parrish spake unto Cameron Hall:
HX-Pro doesn't test and adjust the bias to match different tape formulations,
although there are high-end decks that can do automatic bias tuning.
To understand the concept behind HX-Pro, you have to understand what "bias"
is and why it's used.  Very briefly, it's very-high-frequency (not VHF though
:) sine signal, typically 40kHz-80kHz or higher, that boosts the signal on
the tape to avoid "zero-crossing" distortion.  When there's significant
high-frequency content in the input signal itself, that signal acts to
partially bias the overall signal.  In these cases, HX-Pro lowers the level
of the record bias, thereby allowing more headroom for the higher audio
frequencies.  more headroom means a hotter signal can then be recorded
without pushing the tape into saturation (and thus, distortion).

assistant: I am in charge of an average sized P.A. system. It includes
an old 24 channel mixer desk, two TOA amplifiers, two
cassette decks, 3 radio mikes, plate mike a stand mike
and about 12 instruments, including 2 DI boxes and the
rest being microphones of some kind or other. There are also
two large forback speakers, with slaves. The 'Loop' system is
for the hard of hearing and is used with an old 30 watt microphone
amplifier and a piece of wire which goes around the whole building's
edge.
    The problem being, is that the electric guitars are picking up the loop.
Is there any way to stop this from happening? Wrapping the pickups in
baking foil etc..? I have found that rotating the guitars through 45 degress
cuts it out, but I need something more permanant then having all the
guitarists sitting funny...

For example, I seem to recall Dolby tones being 400 hertz (sine wave?) at a

 Regarding loop systems, most used hereabouts any longer are IR systems
using an LED array at the front of the room and recievers used to tune
to them. Can be much better than a mag loop system and not cause

Trying to remember the name of the manufacturer of these systems, it's
been a few years since I've designed systems for large rooms with ADA
access requirements.

assistant: Hi Kenneth,
 As much as I have liked what Dolby has done to make impossible or
unlikely mediums sound reasonably good, proper alignment of Dolby
systems is the biggest problem to this noise reduction system. Alignment
of the tape to the recorder and using that same kind of tape for future
recordings is one thing to do. During that alignment, Dolby tone should
be set by the technicians to that ideal level during recording, allowing
a transparent playback of the original material. That is the end goal.
Ideally, the technician tweaking up your Dolby should mark the input
controls to that ideal level, which if not properly setup, would have
the Dolby working at times it shouldn't causing "distortions" of the
signal (different than intended levels of companding, etc.). That should
then be the ideal level for the Dolby, and as long as you match levels
coming in to that record level, then all should decode fine on the
playback.
 So many people claim that Dolby takes all of the brightness out and
other claims which are either directly due to misalignments of the input
levels during recording, or playback levels on the decode side, or
listening to tapes too much without Dolby playback then using a Dolby
system which will expand the compressed bands back to their normal
levels which to someone listening to the tape without Dolby for too
long will now think is sucking the highs out. Much of this also comes
from the same crowd that seems to use speakers that make only pitch on
anything below about 150 Hz, and that has to be much louder than
anything else.
 Bottom line, if you have a Dolby deck and wish to record with it a lot,
select a tape formulation and length that you like, take it and the
recorder to your friendly neighborhood audio technician to align for you
to that tape formulation and record away in bliss!

Well, I can't say from experience (I'm only 28 ;) but we did cover all this
stuff in an audio-engineering course I took about 9 years ago.  Now that you
mention it, I do recall hearing that a permanent magnet was originally used
for "bias".  Anyone who knows how the process works will realize the inherant
problems with this :)
One advantage to using the high-frequency sine wave is that it's naturally
filtered by the limitations of the playback head itself (most of which won't
respond to a signal beyond 17kHz or so).
PMs were (and probably still are, in some instances) also used for the "erase
head".  This, of course, has obvious drawbacks of its own as well... such as
the stray magnetic field that would always be present in the general area.
Of course, an alternating field is also far more efficient at erasing the
tape.

  In a message on 23 March, you wrote to me in part :
A range of magnetic fields from the quantum[?  ] minimum to some higher power
level magnetize metal and oxide (Fe, Cr, et al.  ) "nonlinearly".  This

is not frequency dependent, so a supersonic freq magnetic field of adequate
strength puts all audible material in the zone of linear response.  ?  I
hadn't really considered that program material biases the tape, and that
XPro
fixes this to maintain a more constantly normal bias.  The first magnetic
recordings were on iron wire, and unbiassed, I think I read, the highest bias
frequency I recall from the 80s is 125khz.

Certain play heads can read shorter wavelengths than record heads can
write, for equivalent gap size, because ?
A stronger, video bulk tape eraser is needed to erase metal audio tapes, or

several years ago.
Recent articles say stronger magnetic fields are being created every several
months. And this work may help recording progress.

assistant: I use a PA System, Average ish but the auditorium has

    The problem is that the loop is being induced into the
forback amplifiers and electric guitars and causing
enormous problems. The loop is running 4-ohms off
a 25Watt Mic-Amp. The musicians are basically sitting
on top of the wire which hhas been placed under the carpet.
    One idea was to move wire around the musicians so they
were outside the loop area and so decreasing the effectivness
as that point. This means pulling an enourmous are of carpet
up, moving 300+ chairs, pianos, organs, mics etc.. An
enourmous job so I am looking for another option.
    Is there an pickup replacements that you can think of. The
guitar is a Washburn, and has a humbuker pickup.. It sounds
awfull and so I don't want to replace all the pickups with those.
I have thought about running lead taping around the areas
near the musicians, over the wire but the tape is very expensive.
Any ideas...
