Hillendale THp With Mulftr Transistor Sbw.
The Hillendale Theatre in Baltimore, Md. is one of the most modern motion picture theatres opened in recent years.
This theatre of 960 seats has comfortable seating, adequate air conditioning, a screen size giving wide viewing angles and the most modern American-made century 70mm-35mm projectors equipped with multiple channel transistorized amplification and electronic sound changeovers. The installation was made by the J. F. Dusman Company, Baltimore, Md.
The photograph shows the interior of this modern theatre having five Altec Lansing theatre speakers back of the screen and 12 surround speakers permanently installed in ceiling coves. This unique placement of the surround speakers give smooth powerful reproduction of effect sound adequately reinforcing the stereo reproduction from the stage speakers.

pie channel amplification. The closeup photograph of the transistor amplifiers clearly shows the 6 channels of 70mm amplifications, together with 4 channels of 35mm CinemaScope plus the single channel optical amplification. As shown, each complete channel may be replaced as easily as a vacuum tube, as it is contained in an enclosed "can" having "standard" methods of plug-in. There are no vacuum tubes in this system and therefore no thermionic or emission ground noise.
There being no switch contacts or relays in the speech circuits the "noise" created by such devices ordinarily used for selection or changeover is eliminated.
The power amplifiers, turntable and junction box are shown. Altec Lansing 40 watt power amplifiers are used.
The installation and line up time for this system was reduced to one day.
This is the first multiple channel transistorized sound system installed in the world and thus the Hillendale Theatre becomes historically an exam
