Interface for loudspeakers with digital input signals based on IEC 60958
IEC 62537:2010(E) specifies the requirements for a digital loudspeaker interface based on the IEC 60958 series of standards and the MIDI specification. It 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 Annex C of this standard.
Schnittstelle für Lautsprecher mit digitalen Eingangssignalen nach IEC 60958
Interface pour haut-parleurs avec signaux d’entrée numériques basés sur la CEI 60958
La CEI 62537:2010 spécifie les exigences d'une interface pour haut-parleurs numériques basée sur la série de normes CEI 60958 et sur la norme MIDI. Elle optimise la souplesse et la valeur en combinant ces normes qui étaient précédemment distinctes. Les deux normes fournissent ensemble une interface numérique simple et souple pour haut-parleurs. La présente version bilingue, publiée en 2010-09, correspond à la version anglaise. La version française de cette norme n'a pas été soumise au vote.
Vmesnik za zvočnike z digitalnimi vhodnimi signali po standardu IEC 60958 (IEC 62537:2010)
Ta mednarodni standard določa zahteve za digitalne vmesnike za zvočnike, osnovane na seriji IEC 60958 standardov in MIDI specifikaciji. Z združevanjem teh prej ločenih standardov maksimira fleksibilnost in vrednost. Skupaj ta dva standarda zagotavljata preprost in fleksibilen digitalni vmesnik za zvočnike. Primeri uporabe vmesnika se nahajajo v Dodatku C tega standarda.

INTERFACE FOR LOUDSPEAKERS WITH DIGITAL INPUT SIGNALS
BASED ON IEC 60958
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by i
