Quand ces enceintes de relais, \u00e9galement appel\u00e9es rappels ou satellites, sont correctement align\u00e9es temporellement avec les enceintes principales de la sc\u00e8ne, la musique est claire, sans \u00e9chos, les annonces sont intelligibles et la performance globale agr\u00e9able.<\/p>\n\n\n\n<p>Commen\u00e7ons par quelques \u00e9l\u00e9ments de base. Tout d'abord, toutes les enceintes, y compris les enceintes de relais, doivent \u00eatre tourn\u00e9es vers le public et orient\u00e9es correctement. Le son se d\u00e9place \u00e0 344 m\/s (ou 1128 pieds\/s) et sa vitesse varie principalement en fonction des changements de temp\u00e9rature et un peu des variations d'humidit\u00e9. \u00c0 20 C (temp\u00e9rature de r\u00e9f\u00e9rence), la vitesse du son est de 344 m\/s, \u00e0 5 C elle est de 334 m\/s, \u00e0 35 C elle est de 352 m\/s. C\u00f4t\u00e9 public, il faut que le son \u00e9mis par les enceintes de rappel soit coh\u00e9rent temporellement avec celui issu des enceintes de fa\u00e7ade, qui a mis un certain temps \u00e0 traverser le public. <\/p>\n\n\n\n<p>Pour ce faire, il faut retarder la ou les enceinte(s) de rappel. Comment proc\u00e9der ? C\u2019est simple : nos enceintes des s\u00e9ries K.2 et KS vous permettent de r\u00e9gler leur retard int\u00e9gr\u00e9 en m\u00e8tres, pieds ou millisecondes. La fa\u00e7on la plus simple de r\u00e9gler chaque enceinte de rappel est de mesurer la distance entre les enceintes de fa\u00e7ade et celles de relais et d'entrer la valeur dans chaque enceinte n\u00e9cessitant un retard. Si vous travaillez sous des temp\u00e9ratures extr\u00eames (par exemple 5 C ou 35 C), ajustez votre ou vos retards en tenant compte de la variation de la vitesse du son.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img decoding=\"async\" width=\"690\" height=\"703\" src=\"https:\/\/blogs.qsc.com\/app\/uploads\/sites\/3\/2020\/09\/KS-Series-Delay-Setting-Image.png\" alt=\"\" class=\"wp-image-2541\" srcset=\"https:\/\/blogs.qsc.com\/app\/uploads\/sites\/3\/2020\/09\/KS-Series-Delay-Setting-Image.png 690w, https:\/\/blogs.qsc.com\/app\/uploads\/sites\/3\/2020\/09\/KS-Series-Delay-Setting-Image-294x300.png 294w, https:\/\/blogs.qsc.com\/app\/uploads\/sites\/3\/2020\/09\/KS-Series-Delay-Setting-Image-48x48.png 48w, https:\/\/blogs.qsc.com\/app\/uploads\/sites\/3\/2020\/09\/KS-Series-Delay-Setting-Image-250x255.png 250w, https:\/\/blogs.qsc.com\/app\/uploads\/sites\/3\/2020\/09\/KS-Series-Delay-Setting-Image-550x560.png 550w, https:\/\/blogs.qsc.com\/app\/uploads\/sites\/3\/2020\/09\/KS-Series-Delay-Setting-Image-177x180.png 177w, https:\/\/blogs.qsc.com\/app\/uploads\/sites\/3\/2020\/09\/KS-Series-Delay-Setting-Image-491x500.png 491w\" sizes=\"(max-width: 690px) 100vw, 690px\" \/><\/figure><\/div>","protected":false},"excerpt":{"rendered":"<p>Dans une grande salle ou \u00e0 l'ext\u00e9rieur, il peut \u00eatre n\u00e9cessaire d'installer des enceintes suppl\u00e9mentaires relativement \u00e9loign\u00e9es de la sc\u00e8ne principale ou de l'\u00e9v\u00e9nement afin d'assurer une couverture sonore ad\u00e9quate pour l'ensemble du public.
