Extracts from Marconi Catalogue......
1960
The Company is specialising in modern system planning even to the most exacting customers' specification. Marconi consultants, project engineers, architects, and acousticians are always at the service of clients during all early stages of their organisation. Marconi engineers also deal efficiently with the whole aspects of installation, staff training, and initial traffic of the service.
No two organisations use identical methods of operation. The widely differing function and usage that has evolved has prompted the Company to the first developments of custom-built sound equipment. The Company's 'tailor-made' apparatus, accessories, studio suites, reporting and recording vehicles and whole broadcasting-house schemes have become a well-established branch of its business and have earned a fine engineering tradition second to none.
1963
The past few years have shown a great increase in the demands made on sound equipment, both in broadcasting and in television. Not only have the number of control channels increased but far more complex and flexible auxiliary facilities have been required for studio and outside-broadcast work.
We therefore provide a range of sound equipment which will meet these demands without losing sight of the more modest, but equally important, requirements of the small studio operator.
There has been an increase too in the number of outside broadcasting vehicles equipped by the Company for sound broadcasting authorities. Our experience with sound, to day nothing of television, radar and military communication vehicles enables us to bring expert knowledge to bear on the many problems of broadcasting and recording vehicle design and equipment.
1964
"Over the past years there has been a great increase in the demands made on sound equipment, both in broadcasting and in television. Not only have the number of control channels increased but far more complex and flexible auxiliary facilities have been required for both studio and outside-broadcast work".
"We therefore provide a range of sound equipment which will meet these demands without losing sight of the more modest, but equally important, requirements of the small studio operator".
1965
Broadcasting Division's range of sound equipment has changed considerably during the past few years and even the most modest operator can find a performant solution to meet his particular requirements.
The following two items exemplify the wide range of equipment available:
- Small, elegantly styled transistor peak-performance meters and volume meters
- 12-channel Mixer type B1103 is a very competitive sound mixer offering all the facilities required for television broadcasting

Note 1
The BD956B Mixer with associated 1701 Loudspeaker Monitor are primarily designed for outside broadcast use offering four low-level inputs for microphones or transcription heads. Both units can operate off a variety of standard mains voltages and 12 volt batteries.
Note 2
The BD972 Sound Mixer has been designed for television outside broadcast units and small television studios. It is fully transistorised and can easily be mounted in a customer's control desk.

Programme Meters (V.U. and P.P)
There are two types of Programme Meter:
- Volume Unit (VU) meter, or Standard Volume Indicator (SVI), which displays a representation of the signal level
- Peak Programme (PU) meter which shows the peak level of the waveform no matter how brief its duration
The following units make up the range of programme meters:
