What is this BS EN 62537 - Loudspeakers with digital input signals about?
BS EN 62537 discusses the interface for loudspeakers with digital input signals based on IEC 60958. BS EN 62537 specifies the requirements for a digital loudspeaker interface based on the IEC 60958 series of standards and the MIDI specification.
BS EN 62537 maximizes flexibility and value by combining these previously separate standards. Together, the two standards provide a simple and flexible digital interface for loudspeakers. Examples for applications of the interface can be found in BS EN 62537. BS EN 62537 specifies the meaning of the standard parameters and their control numbers to be used with the MSC SET command. The control number for standard parameters is in the range 0..4 095. The range 4 096..8 191 is reserved for manufacturer-specific parameters.
Who is BS EN 62537 - Loudspeakers with digital input signals for?
BS EN 62537 on loudspeakers with digital input signals is useful for:
- Manufacturers of loudspeakers
- Product design engineers
- Quality control personnel
- Audio programmers
- Music producers
- Music studios
Why should you use BS EN 62537 - Loudspeakers with digital input signals?
The loudspeaker is controlled through a number of parameters that can be set through MIDI messages. Each parameter has a control number associated with it that serves to identify a particular parameter.
BS EN 62537 defines an optional method to change parameters through NRPNs or through standard MIDI continuous controllers. BS EN 62537 includes a method for how individual parameters are associated with a controller number or NRPN.
The IEC 60958 interface allows transmission of 2-channel digital audio with up to 24-bit word length at a 192 kHz sampling rate. This is adequate for loudspeakers, however, there are additional needs in practice that require standardization, which go beyond what's currently defined in IEC 60958. BS EN 62537 is aimed at fulfilling those needs.
