  • Page 4 Il comodo display a LEDs consente una chiara visione dello ‘status’ degli amplificatori in qualsiasi condizione di illuminazione. Gli AMP SERIES sono adatti a tutti i tipi di utilizzo in cui si richiedano amplificatori potenti, versatili ed affidabili, con dimensioni compatte ed un ottimo rapporto prezzo/prestazioni: dai sistemi di amplificazione da trasporto alle installazioni fisse, dai sistemi di multi- amplificazione ai setups casalinghi.
  • Page 5 AMP SERIES Norme di installazione ed uso Prima di collegare l’amplificatore alla presa di corrente, accertatevi che la tensione di rete corrisponda a quella indicata sul retro dell’apparato (è accettata una tolleranza fino a ±10%). Prima di collegare il cavo di alimentazione alla presa di rete, accertatevi sempre che questo non sia danneggiato o addirittura con fili scoperti.
  • Page 6 AMP SERIES Norme di installazione ed uso E’ buona norma, per non compromettere il corretto funzionamento del’amplificatore, evitare di posizionarlo per tempi troppo prolungati in luoghi esposti all’azione di agenti atmosferici (umidità, temperature molto elevate, ecc.), all’accumulo di polvere e a vibrazioni troppo intense.

L’eventuale accensione di questi LEDs segnala l’attivazione di una delle protezioni che salvaguardano le diverse sezioni dell’amplificatore (ed eventualmente anche i diffusori) in caso di condizione anomala di funzionamento. In questi casi, l’erogazione della potenza viene normalmente sospesa fino al...
  • Page 10 Prese d'aria del sistema di raffreddamento dell'amplificatore. La ventola del sistema di raffreddamento degli amplificatori AMP SERIES crea un flusso d'aria con scorrimento in direzione davanti/dietro: ciò significa che l'aria viene prelevata dall'apertura posta sul fronte e, dopo aver raffreddato i dissipatori ed il trasformatore di rete, viene espulsa attraverso l'apertura posta sul retro.
  • Page 11 AMP SERIES Funzioni & controlli Collegate alle uscite dell'amplificatore solo diffusori (o sistemi di diffusori) che rientrino nei limiti di carico di potenza e di impedenza dichiarati per l’amplificatore stesso (vedi ê Specifiche tecniche). Usate solo cavi per diffusori (cavi o piattine a 2 fili, solitamente 1 rosso e 1 nero): non usate mai cavi schermati o “cavi segnale”...
