![]() I wrapped them all up in electrical tape to keep them all together. Connect five 9V batteries in series an voila: 48 VDC. There aren't a lot of 48V battery packs on the shelf at the local hardware store, but it turns out they are easy to make. If nothing else, this could serve as a reference for future designs, as you won't get much cleaner. So, I though I would try making a 48V battery, and run the phantom power from that. I wanted something cleaner, cheaper, and quick to throw together.īatteries are pure DC. Besides, all of these are going to have some AC ripple at 60 Hz, which is bad for audio. Step 2: Convert the 48V AC into pulsating 48V DC using a full-bridge rectifier. I didn't have any of that stuff, and I did not really want to play with the line voltage. Step 1: Lower the 110V/220V AC to 48V AC using a transformer. Most were pretty old-school, with individual rectifier diodes and caps, and some kind of transformer. Most of them ran off of a custom 48V supply that was stepped down and rectified line voltage (120 VAC here in North America). Register today at looked up several phantom power supplies. ![]() The Gigamon Community is a great way to get answers fast, learn from experts and collaborate directly with other members around your areas of interest.

Repeat Step 2 through Step 5 for the other power supply in the GigaVUE‑HC2 chassis: Run the wires to avoid obstructing airflow for the adjacent fans. You will need a Mic Preamp with 48v phantom power & XLR cable to use it. hello dosto Namaskar toh dosto kaise ho aap log, dosto aaj ki video me Maine 48v phantom power supply ka review diya after using few months and isko proper t. ![]() Important: As shown in Figure 1, the leads to the DC power supplies on the GigaVUE‑HC2 node should attach from the side of the chassis away from the terminal block. Audio-Technica AT2020 XLR Condenser Microphone. ![]() Replace the safety cover over the power terminals.Ĭonnect the neutral and negative power cables to the DC power source as follows:Ĭonnect the neutral wire to the 0V (RTN) connector on the DC power source.Ĭonnect the negative wire to the -48V connector on the DC power source. The bottom connector on the DC power supply is the -48V connector. The top connector on the DC power supply is the 0V connector. Remove the safety cover from the power terminals.Ĭonnect the power supply ground terminal () to earth ground.Ĭonnect the positive and negative power cables to the screw terminals using a Phillips screwdriver. To connect a -48V DC input to the screw terminal DC power supply: 1. This section provides instructions for connecting a -48V DC power source to the DC power supplies. The GigaVUE‑HC2 is available with DC power supplies.
