Date: Sunday, November 22, 2020, 7:00-9:00 PM

Place: ZOOM Video Conference (Scroll down for details)

Featured Guests: Chris Hart, Audio/Video Consultant

Topic: Chris Hart, Technology Consultant, will walk us through his state-of-the-art, home Audio/Video system

Fellow BAS member, Chris Hart will explain all aspects of his home Audio / Video setup.

Chris is a technology consultant and has a background in television and film production. Chris caught the audiophile bug at 13, when he bought his first hi-fi component from Tweeter in Hyannis. He loves making the home audio / video experience the best it can be and feels that great sounding music in every room of the house is one of the greatest joys in life. This goal is what drives both his system building at home, as well at the homes of clients.

Another central motivator has been to have all of his media accessible from anywhere in the house (and even outside the house) as readily and easily as possible -- something that the entire family enjoys daily. Chris and his family "cut the cord" (mostly) a few years ago and at this point about 95% of what they watch is via AppleTV -- including the movies that originated on discs. And 8 music zones are available at their whim -- either playing the same music in sync, or each zone working independently.

In a presentation that will walk you through all the rooms, Chris will detail every aspect that makes it all work. Topics discussed will include HDTV, Cord Cutting, Internet, networking, Wi-Fi, servers, streaming music, PLEX, SONOS, speakers, surround sound, Atmos and more. This will be an in-depth look at Chris’s setup that is sure to be interesting and educational. Follow the ZOOM information below to join us.

November 2020

1.  Shoptalk was a radio show on WBUR that ran in the 70s and 80s and played a significant role in the growth of the BAS. David Satz has unearthed and copied some 70 shows from that period. If there is interest we may make them available to BAS members for a donation. Guests include Roy Allison, Mark Davis, Rene Jaeger, Andy Petite, Bob Berkowitz, Joel Cohen, Richard Burwen, Tom Holman, Mitchell Cotter, Ben Zander, and Tom Horrall.

2.  The Zen phono preamplifier  from iFI seems like an extraordinary value at $149. It has low noise MM and MC stages, switchable loading for MC cartridges, accurate RIAA, and switchable subsonic filter. Compared with the DB Systems DB-8 and DB-8HG phono preamplifiers (introduced in 1995) the specs are not as good except perhaps the MC noise. I would be interested in testing one on the bench. If anyone buys one, I would like to borrow it for a few days. I will pay shipping both ways.

3.  The HiFi Engine library has images, specifications and reviews for thousands of audio components, along with free downloads of owners manuals, service manuals, schematics and product catalogues for amplifiers, pre-amps, power amps, tuners, tape decks, cd players etc.

Thanks to the many visitors who have scanned documents and donated images to the gallery.

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

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)

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
