Nella presente guida vengono fornite le istruzioni per l'installazione e l'utilizzo dell'altoparlante M-Audio DSM2. Tutti gli altoparlanti DSM2 sono caratterizzati da elementi di design di fascia alta e da una circuiteria di controllo di precisione. Garantiscono un'accuratezza tonale, una chiarezza e una gamma dinamica eccezionali in un'ampia gamma di applicazioni. Caratteristiche Gli altoparlanti DSM2 presentano le caratteristiche seguenti: · Funzionamento biamplificato, autoalimentato · Ingressi analogici e digitali selezionabili · Châssis a regolazione personalizzata · Materiali e design del driver avanzati · DSP interno per il crossover incrociato, l'EQ e il trimming del volume Contenuto della confezione · Un altoparlante DSM2 · Un cavo di alimentazione CA · Quattro attenuatori per l'isolamento acustico · Scheda informativa per la registrazione di M-Audio Informazioni sugli altoparlanti Amplificatori Gli altoparlanti DSM2 M-Audio sono dotati di amplificatori incorporati. Biamplificazione I driver HF e LF DSM2 sono alimentati in modo indipendente da due amplificatori di potenza interni a bassa distorsione distinti. Design della classe D Gli amplificatori della classe D DSM2 combinano l'efficienza e le dimensioni di un amplificatore digitale con la precisione, il controllo e la qualità audio dell'amplificazione lineare. Capitolo 1: Introduzione 1 Ingressi Gli altoparlanti DSM2 di M-Audio sono dotati di ingressi analogici o digitali. Per selezionare il tipo di ingresso desiderato, utilizzare l'interruttore per la selezione dell'ingresso situato sul pannello posteriore dell'altoparlante. Per ogni tipo di ingresso sono disponibili due connettori. Ingressi analogici Il segnale di ingresso analogico viene campionato in ingresso e viene elaborato digitalmente fino a quando non raggiunge la fase di amplificazione di potenza Gli ingressi analogici disponibili includono i connettori XLR e TRS da 1/4 di pollice bilanciati. Questi ingressi vengono sommati in modo che sia possibile utilizzare contemporaneamente entrambi i connettori di ingresso. Ingressi digitali Gli ingressi digitali rilevano automaticamente la frequenza di campionamento e la risoluzione in bit in ingresso e accettano segnali con valori fino a 192 kHz/24 bit. Gli in ...
