July
2021 ONLINE MEETING NOTICE
DATE: Sunday, JULY
25, 2021, 7:00 PM EST
PLACE: Zoom online
FEATURED GUEST: You
TOPIC / ACTIVITY:
Internal and necessary business items
Our ZOOM Meeting for
July will be an ‘Open Forum’ for
all viewers to contribute/present their latest
research, interest, or project.
This opening gives the
Society a rare chance to catch-up on internal
and necessary business items, and is it this
right time to return to in-house meetings?
David Hadaway will present
his latest, well researched consumer information.
Alvin Foster will talk about his latest good
findings on the Zoom multichannel recorder,
and his disaster experience with the DSP’s
ambiMIK-1.
The second agenda item
will include catching up on writeups of previous
meetings for the newsletter. The BAS now pays
meeting summary writers $150. Over the years,
we have a backlog of unreported meetings.
It’s easy, the entire meeting can be
downloaded or supplied on a CD. How can we
get more writer participation?
Please log in prepared
to add to our ‘Open Forum’

THE
BAS MESSAGE
July 2021 |
|
1.
From the June 2021 Stereophile:
HiFi by the Pound? From
the PrimaLuna ad: "$9k for a 15lb preamp?!
If you want to
pay $9,000 for a 15 lb preamp with mediocre
parts, that’s your business. If you want
to pay 4,699 for a 53lb preamp crafted with
the finest exotic parts, that’s our business.
Learn the truth on the
PrimalLuna Youtube channel”
2. HYPSOS by
Ferrum
Revolutionary power supply
Linear/switching hybrid design — 100-240V
AC in — 5-30VDC out — 6A/60W
HYPSOS comes with one
of the two high quality DC power cables fitted
with a 5.5 x 2.5mm and a 5.5 x 2.1mm DC plug,
to connect to the most commonly used DC inlets.
Other DC plugs can be made to order. $995
3. I see MQA
technology continues to be licensed. Have
there been any rigorous tests?
Radio Paradise, an internet radio station,
has signed an exclusive deal with MQA.
4. Need a recordist:
A friend is working on a multilocation recording
project, and seeks someone to record one part
of it: a calliope in southern New Jersey.
Requirements: ~two hours of music; anticipating
two-mike stereo on one side, same on the other,
plus a single mike at the end where the drum
is located. Recording at 24bit/96k per channel
is required. The time frame is within the
next two months (sooner is preferable).
Contact me and I can put you in touch with
the project manager.

other meetings and notices which
may be of interest to BAS members |

| BAS
MICROPHONE CLINIC REPORT ! |
| In September 2009
the B A S held a microphone clinic, testing 37 different
microphone models. The ambitious nature of the clinic
effort, the extent of data collection, the number
of individuals involved in microphone testing and
in writing various sections of the report, and the
complexity in determining how to construct the clinic
report and make it available to members resulted it
not being published until now. The dataset is extensive.
Representative samples were
included in the abbreviated report in "The
B A S Speaker"
(Fall 2015; v37n3)

CLINIC PAGE for more...

When collecting
and plotting "noisy" data
it is often useful to have Microsoft
Excel plot a Trend Line through it.
If that data is to be used for
further work, it may be necessary to
have an X-Y table of the Trend Line.
That is not easy to get and this paper
will show how to do it.
Joseph DeMarinis
has a new article here: Extracting
Numerical Data from an Excel Trend Line
