Distortion, impedance & the 10:1 rule.

PROBLEM: I am troubleshooting an audio system installation in a large conference room that can be divided into three separate rooms. Each room has a dedicated powered mixer with distributed ceiling speakers and the source equipment is in a roll around portable rack. The idea obviously is that the customer can take the source equipment to, whichever room is in need or it can be shared between any combinations of the three. The only problem is if one of the powered mixers is turned off because a room is not in use it causes distortion in the other areas. From what I can tell who ever did the original installation has simply paralleled the sources to all three mixers. How can we alleviate this distortion. Continue reading

James B. Lansing (Altec & JBL)

James B. Lansing

From the 1920s to the 1950s, James B. Lansing was at the forefront of creating leading speaker systems used in motion-picture theaters. In the 1930’s, Lansing named his company James B. Lansing Sound Corp. (JBL).

JBL has a long history of building speakers for recording studios as well as movie theaters. In fact, the speakers developed for use with the first ”talkie”, ”The Jazz Singer,” in 1928, were from JBL. Historically, the main challenge for JBL was to make speakers that could fill a theater using only the few watts available from the amplifiers of the day, and still be intelligible when playing from behind a screen. The same speakers were used in the studios where movie sound was mixed so the producers could hear what the moviegoers would hear. Continue reading
