The Film Daily (1930)

THE Sunday. August 3, 1930 DAILY Theater Equipment U. S. ARMY M. P. SERVICE HAS 3 TALKER AIRDOMES Three open air theaters presenting talkers are now being operated by the Motion Picture Service division of the U. S. Army. They are located at Fort McClellan, Anniston, Ala.; Camp Bullis, San Antonio, Tex., and Camp Knox, Louisville, Ky. At all three outdoor shows, reproduction has been reported excellent. An innovation of the Airdome at Camp Bullis is a projection room 7 ft. 3 in. by 12 ft. 8 in., constructed on a Mack truck chassis, equipped with two Simplex projectors, and complete sound-on-film reproducing apparatus. This projection booth on wheels also contains a non-synchronous device for use in playing phonograph records, and provision is made for carrying the sound screen and speakers. Set-up for a show can be completed in 30 minutes at anjr point where a 110 volt 60 cycle current supply is available. Those responsible for the building of this ingenious plant are W. E. Crist, branch manager of the Army Motion Picture Service for the Eighth Corps area, Technical Sergeant A. C. Rounds, Major L. G. Harer and Sergeant Anson O'Connor. Premiere Record Service Increases Music Library San Francisco — Increased demand for synchronous records has prompted Premiere Record Co. to add new sets of records to its present library. There are six records to a set, playing time of each record, is nine minutes. The set includes recording for exits, marches, overtures, etc. Stanley Frame Co. Moves Following the trend of exhibitor trade in New York, Stanley Frame Co. has moved its offices from 727 Seventh Ave. to the Film Center Bldg. Shaul's Reopens Richfield Springs, N.

No Sound with Discs No sound when using discs may be due to one or more of the following: (a) Switches and rheostats set incorrectly on the amplifier panel. (b) Film-disc switch set in the wrong position. (c) Fading potentiometer in th< "Off" position or set for the wron£ projector. (d) Output fader in "Off" positioi or wrong one being used. (On "B,' "C-l" and "D-l" installations.) (e) Power amplifier AC supply cir cuit open. The primary voltmete will then be at zero. Replace th< line fuses if they have blown. (f) Voltage amplifier defective o two tubes in the same stage burne( out. Change to the other voltag* amplifier when one is available. (g) Pick-up defective. Rub the needle with the finger. Swing th fader to other projector, and if soun< comes from that pick-up and not fron. the other, it is usually a sure sign that one of the pick-ups themselves are defective. In that case change pick-ups. Try a new one. Make sure that the contacts on the pick-up are clean and tight. (h) Loudspeakers not plugged in on the stage. (i) Short circuit on the voltage amplifier "A" battery line. Both pilot lamps and voltage amplifier tubes will be "out." Change to the other storage battery. Test the fuses of the four-pole double-throw switch in the battery line. If blown, test for the location of the short circuit as follows: Turn the battery switch off and disconnect the plugs on the input control panel. Insert the new fuses in the four-pole double throw switch. Turn the battery switch "On." If the fuses blow, make the same test vvitli the other voltage amplifier in the circuit. Re-connect the plugs on the input control oanel one a1 a ritni» connected. Operate with this part of the circuit disconnected, if possible. (Of course, in installations ...1 it, „ nli.m o-o ~„* ,,,,, A tVlic (e) Burned out tubes. If at any time during the show the volume suddenly decreases, make sure that all tubes are in operation. {Continued in Aug. 10 Issue) STAGE EQUIPMENT Console Orchestra Elevators Magnescopic-Grandeur Screen BRUCKNER-MITCHELL, INC. 532 West 22nd Street New York If It IsiTt "PYROLOI (That's the general op In 2 colors JADE PEARL and ROSE PEARL Genuine "PYROLOID" Aaron oacua Room 538 200— 5th Ave., N.
