Leggeri e maneggevoli, gli HPX fanno della praticit\u00e0 una delle loro caratteristiche di punta. La tecnologia SMPS e gli efficienti sistemi di raffreddamento consentono di utilizzare un package compatto e portatile, ma allo stesso tempo robusto, per fornire affidabilit\u00e0 e durata anche dopo anni di intenso lavoro. Un filtro selezionabile LPN (low-pass notch) permette di migliorare la risposta degli amplificatori alle basse frequenze, garantendo un punch maggiore e, allo stesso tempo, proteggendo gli altoparlanti dalle sovra-escursioni, oltre a incrementarne la dinamica. Il pannello frontale, con comode maniglie in fusione e filtri anti-polvere removibili, include un sistema completo di visualizzazione a LED e controlli di livello a scatti.<\/p>\n","protected":false},"featured_media":9207,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[72,248,69],"product_tag":[],"class_list":{"0":"post-7455","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-amplifiers","7":"product_cat-hpx-series","8":"product_cat-sound-systems","10":"first","11":"instock","12":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/soundsystems.proel.com\/it\/wp-json\/wp\/v2\/product\/7455","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/soundsystems.proel.com\/it\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/soundsystems.proel.com\/it\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/soundsystems.proel.com\/it\/wp-json\/wp\/v2\/media\/9207"}],"wp:attachment":[{"href":"https:\/\/soundsystems.proel.com\/it\/wp-json\/wp\/v2\/media?parent=7455"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/soundsystems.proel.com\/it\/wp-json\/wp\/v2\/product_brand?post=7455"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/soundsystems.proel.com\/it\/wp-json\/wp\/v2\/product_cat?post=7455"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/soundsystems.proel.com\/it\/wp-json\/wp\/v2\/product_tag?post=7455"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
