How to turn on the 48v power supply of the base station

4 FAQs about [How to turn on the 48v power supply of the base station]

When should I Turn on 48V?

It is always a safe practice to turn on 48V only when you need it to avoid any unwanted damage or alterations both to your gear and sound quality. If your audio interface/mixer has a dedicated phantom power button for each input channel, make sure they are turned on only on tracks that require it.

How do I set up 48V Phantom Power?

To set up 48V phantom power, start by turning off all your audio equipment. Connect your condenser microphone to the console or interface using an XLR cable. Then, locate the designated phantom power switch or button on your equipment and ensure it is turned off. Next, connect the mixing console or audio interface to a power source.

Can a –48 volt DC power a PA?

However, the –48 V DC must first be efficiently converted to a positive intermediate bus voltage before it can be boosted to power the PA or stepped down to a positive workable supply for the digital baseband units (BBU). A power supply with a capacity of 100 W to 350 W was sufficient to cover many applications.

Why do telecom networks use –48 V DC power?

Telecom and wireless networks typically operate on –48 V DC power, but why? The short story is that –48 V DC, also known as a positive-ground system, was selected because it provides enough power to support a telecom signal but is safer for the human body while doing telecom activities.
