The tiny amplifier playing the music is a class D stereo audio amplifier, available from Parts Express, Part # 320-604. The New Folded Corner Bass Horn pair, plywood midrange horns, and Atlas Sound HR-3 horn tweeters provide the acoustic amplification. For the Folded Corner Bass Horns, I am still using the 12 inch woofers and crossovers removed from the KLH CL-3As. A recycled 12Volt, 1Ampere, switching supply that came with a Netgear router is providing electrical power to the amplifier. The NAD amp provides pre-amplification for the phonograph through the "pre-amp out" RCA jacks.
The LP track "No Time This Time" by The Police playing through this high-efficiency stereo system was recorded using a Canon PowerShot S2 IS for audio and a Panasonic Lumix DMC-ZS40 for video. The cameras are mounted to the same frame. Occasionally, you can see the edge of the Canon S2 IS on the right side of the image. I use both cameras to take advantage of the complementary and mutually superior performance of both cameras at once. One has superior audio performance while the other has superior video.
The New Folded Corner Midrange Horn with impedance measurement setup makes a cameo appearance in this video and will actually be playing in a future videos as soon as I have a stereo pair. Also appearing is a framed original watercolor painting of an Ampeg SB12 Portaflex bass amplifier.
