| 7B is shown here, one of the Productions Group of Studios. |
7B, like the similarly sized 6B below it, was intended for speech in plays and for piano music. They could also be used for talks which required piano illustrations. The small triangular shaped listening room (see floor plan) did not contain a mixer. 7B was 19' square and 9' high (3,200 cu. ft.) and had a reverberation time of 0.6 seconds.
The other studios on this floor were:
- 7A (13' x 13' x 9', 1,500 cu. ft., dead acoustic for speech in plays and often used in association with the 6A, the listening room of which was next door. But by 1934 it was used exclusively by the Empire Service);
- 7C (19' x 19' x 9', 3,200 cu. ft., also dead for drama use);
- 7D (13' x 12' x 9', 1,400 cu. ft., for experimental effects or minor productions. Also used instead of the larger effects studio during preliminary rehearsals) and
- 7E (12' x 8' x 9', 860 cu. ft., a gramophone effects studio).
This photo appears in a magazine of about 1936. The area it shows is not identified, but it may be one of the 6th or 7th floor listening rooms.
One of the Music Control Cubicles, showing the control desk and loudspeaker. Here, "a musician with the music score in front of him" carried out "the necessary controlling of the music, checking the quality by means of the loudspeaker shown at the right of the picture." There is more information about how the Music Control Cubicles fitted into the system in the technical section.
