Topic: Tour and Presentation by Phil Hodson, Encompass Systems
Place: Encompass Systems, 8940 Vincennes Circle, Indianapolis 46268

First, a big thank you to Encompass Systems for hosting us last week. The tour and talk by Phil Hodson was most interesting and lots of fun was had by all. Second, a thank you to all the hosts this year: Auralex, CEDIA, Klipsch, Koorsen and Encompass. Without their generosity, this year could not have happened. Thirdly, we have reached the end of our first season as a fully reinstated Section. Kudos go out to all who have made the past year truly worth it. To all my co-Officers and to our Executive Committee, I personally thank you for making my job easier.

We have also reached a beginning of sorts: we have such a great bunch, the continued success of our Section is almost a given. Elections were held on June 12, 2002 at our meeting and I am very proud to announce our Officers for the 2002-2003 Season:

Chair: Barrie Zimmerman
Vice-Chair: Mark Fritz
Secretary: Mike Hayes
Treasurer: Jeff D. Szymanski

Note: The election of Mark Fritz to Vice-Chair has left a vacancy on the Executive Committee. However, since the by-laws state that an Executive Committee can consist of “three or more” members, it was decided to leave the Committee as is.

Well, that’s about all I have. Once again, a very big thanks to all of you. It has been a wonderful experience for me and I think we are well on our way to many solid years of audio exploration.

Best regards,
Jeff D. Szymanski

Topic: Tour and Presentation by Jim Hunter, Klipsch
Place: Klipsch Worldwide Corporate Headquarters

The Section toured the Engineering Division Klipsch, LLC. Klipsch is currently adding 27,000 square feet of new space, which will include an anechoic room, a hemi-anechoic room, a machine shop and several other listening and R&D rooms. The tour was a unique opportunity to see the construction of these types rooms in process. Future meetings at the Klipsch facility will be exciting, indeed! Klipsch is a Sustaining Member of the AES and more information about their products can be found at www.klipsch.com.

Also during this meeting, Ken Bandy presented information on the Stagehand Union in Indianapolis – IATSE Local 30. Members, non-members and students with an interest in becoming involved in IATSE can get more information at http://iatse30.org/.

Keynote Presentation: “Sound System Headroom, Power Ratings, and Related Topics” – Pat Brown, Synergetic Audio Concepts (Syn-Aud-Con),
Place: Hampton Inn Downtown, 105 S. Meridian St., Indianapolis, Maryland Meeting Room

Date: October 17, 2001 @ 6:30 pm
Keynote Presentation: “The EIA-426-B Loudspeaker Power Rating Compact Disc. What’s on it? How do I use it?” – D. B. (Don) Keele, Jr., Principal Engineer, Advanced Development Engineering, Harman/Becker Automotive Systems.
Place: Auralex Acoustics, Inc., 8851 North Hague Road, Indianapolis

The EIA-426-B standard: “Loudspeakers, Optimum Amplifier Power” (April 1998) specifies a test CD that contains the calibration and test signals for all the tests defined in the standard. This CD is intended to improve the consistency and convenience of the standard and will be made available through the EIA and other sources. The talk described the CD’s test signals and their development, and outlined the procedures to make best use of the disk in setting the power ratings of loudspeakers and the amplifiers that drive them. The revised standard (of EIA -426-A) emphasizes not the ability of a loudspeaker to handle power, but establishes procedures to set the maximum (or optimum) power rating of the amplifier used to drive the loudspeaker. The standard describes procedures to measure loudspeaker power compression and harmonic distortion, and for accomplishing accelerated life testing. The signals recorded on the CD considerably simplify applying the standard because no special signal generation equipment is required. Brief demonstrations of the sound of the signals and their application were presented.
