Turntable technology for Millennials or everything you wanted to know but afraid to ask

Where it all started

It always helps to know where it all started. Thomas Edison invented the phonograph in 1877. His invention was able to record sounds onto tinfoil wrapped around a rotating cylinder. It used a steel needle attached to a resonator mounted at the end of a horn, all of which moved across the cylinder to both record and play back sound. This was a mechanical system that evolved over time to use a wax-coated cardboard cylinder and a steel stylus that moved from side to side in a zigzag groove around the record.

Publisher’s note: ‘Design Notes” is created to feature the informative and well written documentary inside the User Manuals of products to the readership, to offer knowledge and viewpoints that we believe will benefit and even entertain us.

What is NAR?

By | February 18th, 2019|Categories: Dagogo|Tags: , |

I was at a Hi-Fi show in the Fall where, as I walked down one corridor, I heard the same band, playing the same track and not wholly in sync with each other from four successive rooms. It dawned on me at that moment that there had to be more than the apparent restrictive canon of show demo music. Rectifying this situation would involve not only tracking down and listening to new albums releases across a myriad of genres, but finding a most direct and non-labor intensive means of spreading the word.

Frank “Big Boy” Goudie: Jazz on Three Continents Part 3 of 3, San Francisco 1956-64

By | February 15th, 2019|Categories: Dagogo|Tags: , |

 

“Behind his easy smile lies one the most colorful stories in jazz.” Richard Hadlock, San Francisco Examiner, July 1963. Goudie photograph by, and copyright of William Carter, 1962.

Frank “Big Boy” Goudie (b. 1899 Louisiana – d. 1964 California) has been almost completely overlooked by jazz history, a mere footnote until recently.  A skilled musician, his career paralleled the history of jazz itself: origins in Louisiana, migration to Europe, transition to Swing, integration with Latin music and the New Orleans revival.

Speaker Tech Terms

How Well Do You Know Speaker Tech Terms?

I was thinking that some of my readers might like to test their knowledge of speaker design and terminology. I decided to put a little test together for your enjoyment.

Back in 1972 I was working for a company called California HiFi Warehouse, which was a major audio chain back then. FYI, the year after I quit to open Northridge Audio Center, CHFW changed their name to Circuit City. At times I’ve regretted my choice to leave, as I would probably be a lot better off financially had I stayed.

Publisher’s note: Audio Note UK has graciously provided the following article detailing the conceptualization and design of the EVGA Nu Audio Card in collaboration with EVGA.

A jungle out there?

It’s a jungle out there
Disorder and confusion everywhere
No one seems to care
Well I do
Hey, who’s in charge here?
It’s a jungle out there
– Randy Newman

Prominent: standing out so as to be seen easily; conspicuous; particularly noticeable

Popular: regarded with favor, approval, or affection by people in general

Both prominent and popular are commonly used adjectives, so common that the two words and their respective synonyms are found confusing, hence they are innocently substituted for each other.

Spinning round and round

By | December 12th, 2018|Categories: Dagogo|Tags: , |

Hours, days, years were spent listening to records only to find tape cassettes more portable and Compact Discs closer to perfection. Hindsight, as it is, makes me regret so many life choices, but we’ll stick to recorded music formats. It is safer that way for everyone concerned, especially for me.

Tempted by the shiny disc, I spent less time in record/disc shops even though the frequency of my visits remained the same. There was no flipping in the bins, no intense scrutiny of album notes, just the reliance upon the words of friends and strangers.
