Sansui Forging
U.S. QS Link
By CLAUDE HALL
PARIS-
Sansui is launching a major campaign to swing the U.S. hardware and software industry to its QS matrix system. The first step began last week with the arrival from Japan of a licensing representative, Jack Muroi of Sansui, who will be signing up equipment manufacturers.
Starting in May, the second phase gets underway as Sansui starts a vast educational program.
John Mosely, consultant engineer to Sansui and owner of Ferber Studios in Paris, said that Sansui already has a book on quadrasonic available for sound engineers, "but the firm is now preparing two more manuals one of a semi-technical nature for salesmen in record and hardware stores and the other for the general public to inform them of what's available in regards to quadrasonic sound." These two additional manuals will be out by May and distributed by Sansui.
Also in May, Sansui will launch a series of educational meetings and demonstrations in key cities. Dealers from both hardware and software will be invited to hear the Sansui QS system and ask questions. The first meeting will be held in Los Angeles right after the annual convention of the Audio Engineering Society.
"But, within the year we expect to have meetings in every major city in the U.S. and Europe,” Mosely said. "Representatives of Sansui in Japan will be holding similar meetings there.
"We don't intend to get into a dollar fight with CBS or RCA on our various systems. We plan to spend our money in such a way as to help people the most, especially the record and equipment-buying people who keep us in business."
To illustrate Sansui's commitment to the public, he said, the firm “will modify and/or update early
Sansui equipment.
People will be able to send their early equipment back and get new circuitry put in at very modest charges to bring their units totally up-to-date for quadrasonic. Sansui takes its obligations to the public very seriously."
New Sansui units, Mosely pointed out, have discrete capabilities . . .
"I'm speaking of the X series. You can put sounds anywhere in a 360-degree radius and can also put sounds inside the circle. Thus the Sansui system fulfills everything that I believe is the basic requirement for the 4-channel records.
He said that answer to the current battle between matrix and discrete systems might have lain at one time in the UMX compatible matrix-discrete system developed by Dr. Duane Cooper of the University of Illinois. "I, myself, had succeeded in putting the matrix with a 30 kc carrier, which is much the same as the CD-4 system uses. And I got good matrix reproduction as well as discrete reproduction. This proved to me that the carrier-matrix type of record was practical."
Now, however, with several labels firmly committed to different systems, the answer might lie in a "detector" within the amplifier which would automatically switch from discrete to matrix or matrix to discrete, depending on what type of record was being played. "I don't think the public likes to push a button if the systems must co-exist.”
Movie Project
For himself, he's firmly committed to Sansui matrix and is even working on music for a new movie that will, via the Sansui QS system, feature 12 separate channels of sound in the theater. This will be done by matrixing the music into the six channels currently available on film tracks.
As of the end of January, the major emphasis in quadrasonic still rested with regular matrix (the Sansui system is regular matrix), he said. In a study conducted by Sansui, by the end of January there were 14 hardware manufacturers creating equipment with regular matrix in Japan, another 17 in the U.S. As for records, he said there were 274 regular matrix quadra-sonic records available in Japan, plus more than 100 in the U.S. In comparison, SQ had 10 manufacturers of hardware in production in Japan and six in the U.S., while CD-4 had four in Japan and none in the U.S. As for records, there were 102 SQ records on the market in Japan, he said, and 155 CD-4, while the U.S. had 102 SQ records and 5 CD-4 records available. He admitted that these figures were already out-of-date because the quadrasonic industry was moving so fast. "I spent some while a couple of weeks ago in Japan visiting 56 shops in all . .. and I found that a total of only 35 CD-4 demodulators had been sold in the past month. In Japan, most of the sales have been in the complete consoles. which include both demodulator and matrix units built-in, "But there's no doubt that quadrasonic is here and here to stay.
Kosaku Kikuchi, president of Sansui, told me that as long as people are interested in the best possible sound quality, the Sansui QS system will be with us. Unless, of course, something better is developed .. which excludes any of the present systems."
U.S. Licensees Soon
At any rate, Sansui should be announcing names of hardware licensees soon. “I know at least 10 companies in the Los Angeles area alone that are ready to go Sansui," Mosely said. "It now only costs about $10 to build in a QS matrix unit in an amplifier at the manufacturing stage. And Sansui is the only system that will give you a truly compatible stereo-matrix record, which no other system can honestly claim. The Sansui quadrasonic record features full frequency range at the maximum recording level.
Thus he expects the number of Sansui records to double by the end of this year and, with the labels who are still uncommitted, you'll find toes going into the water soon. They can't stay out much longer. It's either get into quadrasonic, or else. And most of them favor our QS system.”
