  • The Mounkes Method

    The Mounkes Method is a subject I periodically replay.  If I had to pass only one practical-audio-setup application to friends, this is it.  It is an entry-level audiophile tweak that squeezes more performance without spending a dime. Many moons ago, my late friend Steve Mounkes introduced me to a simple stereo speaker placement method.  He […]

  • Ed’s AV NEWS

    Welcome to Ed’s AV Blog. This site is limited to my rants, musings, & concerns on an irregular schedule. My weekly Ed’s AV News at Ed’s AV offers more concise current information. Select this Blog for a quick link.      

  • The Dave Grohl Speech

    I received a YouTube link from my daughter to an SXSW keynote-speech, by former Nirvana drummer and Foo Fighters founder Dave Grohl. In the 70s & 80s, I tuned in to the descendants of the Byrds and Buffalo Springfield, Crosby, Stills, Nash, & Young, Richie Furay’s & Jim Messina’s POCO, Chris Hillman’s & Graham Parsons’ […]

  • It’s A Matte of Scale

    Grayscale Accurate luminance reproduction precisely ascends and scales, from absolute black to specified white light.  It’s a scale or grayscale that generates accurate colors, much as audio frequency response generates musical timbre.  The grayscale is a prerequisite for high-performance HDR UltraHD video reproduction. Contrast The contrast ratio is the difference between the brightest and darkest […]

  • It’s a good year for custom AV

    Custom AV is in good shape. Home theater system sales have spiked. Nearly half of all installations include multiroom distribution with 4 zones, 8 loudspeakers, which included an outdoor zone. Outdoor Speaker System | Have more fun. Outdoor backyard audio issues are similar to an outdoor concert. The lack of reinforcement from indoor boundaries significantly […]

  • Sales & Referrals

    I read a story by a corporate ad agency CEO. He used wordy big-corp price-enhancing vocabulary. For example, he referred to his ad agency as a “demand generation agency.” Yet his ultimate point was valid and relevant. Word-of-mouth, a low-cost-powerful-effective–method, increases sales. It was not news to me.  In 1973 my business mentor declared, […]

  • 8K Magic or Hype?

    The Magic Window Your TV screen is a flat two-dimensional magic window.  Increasing video resolution, expanding color volume, and a faster frame rate extend the magical illusion.  The best magic windows attempt to convince us the window is reality.  Does UHD 8K TV expand the magic window? Pixels At a comfortable viewing distance, it’s hard […]

  • Should I use an architectural speaker back box?

    A speaker back-box can be used to protect an architectural in-wall/ceiling speaker from construction insulation and/or comply with commercial fire codes.  And if the box is also audio-engineered for the speaker, you’re good.  However, a generic back-box can severely compromise audio performance. I sourced the following information from reputable manufacturers*, plus my 5 decades of […]

  • #4 Next Wave / OLED IOLED Contrast Ratio

    Part 4 of 4 Goodbye LCD Your video source defines potential possible performance.  Connected AV components and interconnecting cable must allow the video to pass unaltered.  Your TV determines the ultimate result.   OLED & IOLED The organic light-emitting diode’s contrast ratio has led OLED TV to the high-performance leader.  Advanced inorganic light-emitting diode technology, IOLED, […]

  • #3 Next Wave / UltraHD (UHD), 8K UHD, HDR

    Part 3 of 4 UltraHD (referred to as 4K) quadruples video resolution from about two million HDTV pixels to more than eight million pixels.  That’s good.  Pixel count is easy to explain, but difficult to see.  8K UltraHD doubles UltraHD (UHD) resolution, which quadruples the number of UHD pixels.   Again, the pixel-count is easy to […]

  • #2 Next Wave / Channels Of Distribution

    Part 2 of 4 I travel a strip of historic US40 almost daily.  Long ago, the interstate highway system drove the old highway off the road map as an obscure alternate route.  Remnants of its past still lie in the trees and brush at the side of the old road — the foundation of a […]

  • #1 The Next Wave

    (1st of 4 parts) Virtual events, trade-mags, and web-search cannot replace personal meetings with friends and reps.  Trade shows, product seminars, and distributor events, and our sales reps are primary sources of industry news and first-hand product information.  I count on their hands-on experience to separate noise from meaningful information.  This hands-on exchange of information […]

  • Keep Pace

    Keeping pace with our industry and technology is essential.  Reliable sources of information and instruction are needed.  We must maintain a solid foundation in the basics of audio and video, which are too often assumed.  More on that soon.  Primary resources include industry associations, manufacturers, and distributors.  For example, CEDIA offers training at a cost.  […]

  • Frisson

            Terms such as audiophile, videophile, or custom AV pro do not adequately characterize the skill of my late friend Steve. Steve was an AV wizard.  He based the foundation of his craft on his assertion that “everything makes a difference.” He would add that his objective was to “minimize the compromise” of the […]

  • Location, location, location

    I lifted this blog from my website Ed’s AV  It addresses the challenging subject of how to choose a retail location.  It is a 9 step process that defines trade area boundaries, locates its trading areas, describes its demographics, and selects a brick-n-mortar home.  But before we proceed, let’s confirm three definitions for clarity. […]

  • Fidelity without truth?

    Several years ago, Samsung released a very good TV.  But this blog is not about their TV.  It’s about manufacturers misleading their customers and right vs wrong. Let’s begin with a historical perspective.  In the fall of 2007 or thereabout, Samsung introduced an LED television.  At the time, I was perplexed.  I didn’t think real […]

  • HDR Ultra-HDTV Part 7

    Ed’s AV Handbook Saving the world from poor fidelity HDR Ultra-HDTV Part 7  System compatibility. Ultra-HDTV home theater system compatibility is critical.     All components and interconnecting cables must be capable of passing a 18Gbps Ultra-HD video signal. This includes the source component,  AV receiver, AV preamp, plus the TV or Projector. However the […]

  • HDR Ultra-HDTV Part 6

    Ed’s AV Handbook Saving the world from poor fidelity HDR Ultra-HDTV — Part 6 Ultra-HD sources   (3/17) Ultra-HD sources currently include Ethernet rental/purchase services, Ethernet real-time streaming, and the Blu-ray disc. Streaming services have a bandwidth issue. 25Mbps seems to be the download speed ‘sweet spot’ for Ultra-HD streaming. Yet the average consumer connection is only […]

  • HDR Ultra-HDTV Part 5

    Ed’s AV Handbook Saving the world from poor fidelity HDR Ultra-HDTV    (3/17) Part 5  More HDMI Tips HDMI uses 19 pins to move audio and video from point A to B.  The pins offer other functions such as the audio return channel (ARC), an Ethernet path, and ‘remote’ control functions.  But that bloody ARC feature […]

    Ed’s AV Handbook Saving the world from poor fidelity HDR Ultra-HDTV   (3/17) Part 4  The High Definition Multimedia Interface HDMI can be the bane of an AV professional’s daily work.  Blank screens, intermittent video, and noisy images caused by inconsistent manufacturing changing specs, and long cable lengths are all too common.  This blog won’t change […]
