What is this BS 6840-2 - Sound system equipment about?
BS 6840-2 discusses sound system equipment with a focus on glossary of general terms and calculation methods. An assembly of equipment that in combination enables sound signals or audio-frequency signals to be processed or transmitted. Such equipment may be, for example, transducers, amplifiers, recorders, etc.
BS 6840-2 is the second part of the multi-series on sound system equipment that provides information concerning the polarity relationship between inputs and outputs. The polarity of an input shall be described either as “inverting” or “non-inverting” as appropriate. Inverting inputs should be suitably marked.
Who is BS 6840-2 - Sound system equipment for?
BS 6840-2 on sound system equipment is useful for:
- Sound system equipment manufacturers
- Audio technicians
- Recording studios
- Audio equipment companies
Why should you use BS 6840-2 - Sound system equipment?
The power amplifiers should be of high quality with respect to signal-to-noise ratio, distortion, and amplitude response linearity. The output power capability should be sufficient for driving all test loudspeakers at the highest sound pressure level encountered in the programme material without clipping
BS 6840-2 discusses power, relative voltage level, source e.m.f., noise voltage, amplitude non-linearity, cross-talk and separation in multi-channel equipment, acoustic characteristics, characteristics to be specified, and method of measurement.
BS 6840-2 helps improve the polarity relationship between inputs and outputs and enhance the quality of sound system equipment.
