Cosa vuol dire alimentazione phantom?

L’Alimentazione Phantom è, nei termini più semplici, una sorgente esterna per i microfoni a condensatore i quali ne hanno indispensabile bisogno per poter funzionare. L’alimentazione Phantom si ottiene trasferendo corrente continua DC al microfono tramite il connettore 3 pin XLR e un cavo microfonico.

Quando si usa il Phantom?

L’alimentazione phantom veniva impiegata nelle prime versioni rudimentali di effetti elettronici. Alimentava spesso i circuiti di un microfono a condensatore. Pur avendo un’alta sensibilità, in questo modo si producevano segnali elettrici a alta impedenza elettrica.

A quale tipo di microfono viene applicata la 48V?

L’alimentazione Phantom 48V standard viene applicata su connessioni microfoniche bilanciate, fornendo +48 volt in Corrente Continua a entrambi i conduttori di segnale XLR (pin 2 e 3).

Cosa significa microfono a elettrete?

Un elettrete è un materiale dielettrico stabile che conserva al suo interno una carica elettrica. Quindi, nel microfono a condensatore a elettrete, la carica polarizzante non viene fornita dall’esterno, bensì è interna e situata nel diaframma o nella capsula fissa.

Come collegare un microfono ad un amplificatore?

La connessione avviene tramite un cavo analogico di tipo XLR (o cannon) bilanciato (per la cancellazione dei rumori), caratterizzato da un connettore XLR femmina che va inserito nel microfono stesso e, all’altra estremità, un connettore XLR maschio per il collegamento all’interfaccia (scheda audio e mixer ad esempio).

What is phantom energy and how does it affect you?

What is phantom energy? Phantom energy, also known as vampire power, represents a draw of electricity that electronics consume while not being actively used. The “off-but-ready” or “standby” power mode of modern electronics add to the total energy use of your home and may account for a significant portion of your electric bill.

How much is phantom energy costing you?

Energy Star estimates that the average household spends a little over $100 per year on this so-called phantom energy. While it may not seem like much, it’s always best to get an accurate reading by using a kill-a-watt energy meter or by unplugging a device when not in use.

What is +48 V phantom power?

Phantom power (labeled as +48 V on most audio equipment) is a method that sends DC voltage through microphone cables. It is best known as a power source for condenser microphones, though many active DI (direct input) boxes also use it. Phantom power supplies are often built into mixing desks,…

What is the difference between phantom power and DC power?

It is unlike phantom power since it is an unbalanced interface with a low voltage (around +5 volts) connected to the signal conductor with return through the sleeve; the DC power is in common with the audio signal from the microphone. A capacitor is used to block the DC from subsequent audio frequency circuits.
