The November 2021 Online AND In-Person meeting notice

DATE: Saturday November 20, 2021  1:30 - 3:30pm Eastern  NOTE DATE & TIME !

PLACE: Kubotek USA, Marlborough MA and on ZOOM

FEATURED GUEST: Dr. Tetsuo Kubo & USA President Bob Bean
https://haniwaaudio.com  508-229-2020

Topic: How does Haniwa realize 3D Audio?

Make the output equal the input! This is the driving philosophy of Haniwa. The music output at the speaker should be the same as the input from the recorded media, whether from a CD player, turntable, or streaming file. Make the output equal to the input is quite simple from a philosophy standpoint, but impossible to achieve in typical component analog system and digital systems.

Haniwa has spent decades developing a music reproduction system that achieves this goal with precise timing, phase, and frequency control that we call Haniwa 3D Audio. We call it “3D Audio” because Haniwa recreates a precise 3D soundstage in your listening room so you can get as close as possible to the original performance.

Robert Bean, Haniwa Audio, said hopefully, we will see you on-line or in person. Our product designer, Dr. Kubo, will be ‘live’ on video from Japan, and I will be in Massachusetts. Building on our past two BAS meetings, we will highlight the phase coherent Haniwa speaker system. For this meeting, we will be discussing analog front ends and other new advancements from Haniwa – tone arm development and the CVC (Current-to-Voltage-Converter). The Haniwa CVC allows sub-ohm cartridges to work in any system by creating a current loop on the cartridge side and using an MM compatible voltage output on the phono preamp side. You have probably already seen the article in Stereophile reporting on this brand-new type of product::

www.stereophile.com/content/analog-corner-310-haniwa-hctr-co-mkii-phono-cartridge-sw1x-lpu-i-phono-preamplifier-page-2

The current loop interacts with the mechanical loop to produce a very stable tracking system. Dr. Kubo will be up and awake halfway around the globe to answer questions about his analog theories and the CVC from the group.

There is a further detailed technical explanation here: www.haniwaaudio.com/technology

Here are music samples you can listen to and / or download before the meeting.

These are high resolution 24/192 PCM WAV files.
They were digitized from LP's using Haniwa's Current Loop Cartridge (.2 ohm impedance) and CDV Current to Voltage converter at ~.5 grams of tracking.

The samples are clips from the following pieces:

1 BachOrgan_Sample.wav  339MB - to demonstrate bass reproduction at low frequencies

2_TheFirebird_Sample.wav  360MB - to demonstrate spatial and sound stage in a classical piece

3_DrumRecord_Sample.wav  196MB - to demonstrate coherency with close to ideal step and impulse response curves

4_JohnCougar_A_Sample.wav  594MB - to demonstrate more modern rock music reproduction

5_Waterboy_A1_Sample.wav  329MB - to demonstrate spatial and sound stage in a jazz piece

6_TheWeavers_B2_Sample.wav  514MB - to demonstrate spatial and sound stage in a folk piece

Refreshments will be available at 3:30 PM.

Directions to the Haniwa Showroom:

KUBOTEK USA, Inc.
2 Mt Royal Ave  Suite 500
Marlborough, MA 01752

We recommend parking in the parking lot right next to Route 20 (on the side of the building with the ReMax sign).

Once in the building, when guests get off the elevator on the 5th floor, they should see Kubotek USA on the glass with the Haniwa logo below it. The doors will be open.

PLEASE NOTE Only vaccinated COVID persons are permitted and masks are recommended.

THE BAS MESSAGE
November 2021

1.  I’ve been selling a lot of surplus DB Systems inventory on eBay (currently 40 auctions).

Ebay wants to sell you a shipping label, but for small items I can do better with First Class Mail (which they don’t consider since there is no tracking or insurance). If it doesn’t arrive I just ship again.

Here is an example where their label is dramatically cheaper.

I sold a box of open reel tape, one pass, weighing 20 lbs, 20” by 12” by 10” and eBay charged the customer $30.70 shipping, based on my supplied weight and size, which is about right for USPS ground. Going to the shipping label page eBay offered to ship flat rate envelope for $8.50, which is absurd.

If you click more options and scroll down, by USPS ground it’s $23.31. Significant savings.

By UPS $14.88. By Fedex $11.88! There’s a Fedex dropoff in the next town so I used that.

Below, 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)

Go to the MICROPHONE 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

Webmaster's Corner:

Once again, for 2021 - and onward - is THE useful industry calendar of audio/related events, with kudos to all who put this list together:
www.stiernberg.com/industry-calendar

Separately, AV-IQ has their event page here:
https://www.av-iq.com/avcat/ctl1642/index.cfm?events

For a fully comprehensve understanding of meetings taking place - both real and virtual - in this ongoing pandemic situation, you need to look at BOTH listings.
