MANY UNUSUAL FEATURES IN RADIO CITY THEATRE
FOUR standard size Photophone reproducing units, an 80-watt double channel amplifier in the projection room, and four 50-inch loud speakers on the stage will be used in connection with the reproduction of sound pictures in the new Radio City (N. Y.), theatre. In addition there will be a public address system, with twenty-five microphones, to reinforce the stage productions.
Unusual features of the installation include a rehearsal system for use in connection with the direction of productions; a stage manager's call system and fifty-two "Acousticon" seat phones, attached to selected seats for the benefit of the hard-of-hearing. Complete radio and phonograph equipment in the projection room will make it possible to

transmit radio or phonograph programmes to the audience at any time.
The rehearsal system is said to be the latest development of its kind. With it the stage director, carrying a microphone, may conduct his rehearsals from any position in the auditorium of the
theater, through the medium of loud speakers on the stage.
The stage manager's call system is another innovation. It enables the stage manager to communicate with any part of the theatre through a microphone on his desk.

NARROW GAUGE SOIJIVD FILM
TNVENTQR having a patented process for narrow gauge sound fihn, the machinery including projector for which is almost completed, invites investigation by a responsible party who is in a position to make a capital investment.
The invention relates to sound on narrow gauge film of from 17.5 nun. down to 8.5 mm. in width. The process, which has already been successfidly demonstrated, provides a much larger image than has been available heretofore and produces a pseudo-stereoscopic efSTect without employment of a costly or complex optical system.
The inventor has had long experience in the sound recording and reproduction field and can provide excellent references.
