Passive and Active bssound
20/08/2007 · A ribbon mic designed for phantom with a transformer to match is a good solution, but it does now require phantom power. Strapping on an external active circuit would work OK, and maintains the flexibility to not require phantom. But it requires the user to always use it when necessary, so it's not foolproof. A passive circuit is going to compromise audio performance, and probably has to be... 26/02/2008 · Generally, phantom power cannot be provided through a splitter transformer or a ground lifted split as only the AC components are inductively coupled not the DC components. I.e., it doesn't pass DC phantom power at all. Active splitters have their own microphone preamps and with that, with phantom power supplies included within the splitter. So that's really not a splitter but a "multed" …
Phantom Power thread opens doors for other thoughts.
18/10/2008 · This should be considered a design flaw, but ya gotta make it work - either turn off the phantom, or use the unit's 1/4" out through a DI or an isolation transformer …...A noisy transformer is often the sign of a failing transformer. I had the case in my Copal FP-220 flip clock radio. The transformer was buzzing, and worked for 30 seconds, then shut down. I replaced it with a generic 220v-9v transformer, and everything is working like new now!
Ask Jonah Addressing A Long-Standing Phantom Power Myth
2/06/2013 · The board(s) that receive their signal through the transformer splits cannot supply the phantom as it will not pass through a transformer. I would try to make sure that the direct split board is the only one with phantom on just as a general rule anyway. how to get depth of field in your photos A noisy transformer is often the sign of a failing transformer.

A transformer allows Hot/Cold signals to pass, but does not allow the electrons from the ground signal to pass through thus removing the hum. There are dedicated hum eliminators that really just have inputs and outputs, and a isolating transformer in between. Such devices include the
- 27/02/2018 · Phantom will not pass through transformers. If you use a split snake with transformers and want to power mics, you need to not use the transformer isolated side to power the mics/DI's. If you use a split snake with transformers and want to power mics, you need to not use the transformer isolated side to power the mics/DI's.
- The Radial JS2 has one transformer-isolated output, which cannot pass phantom power to the mic at all and is intended to provide an electrically isolated feed for a separate recording system. The second (‘Direct Thru 2’) can pass phantom power, but only if the ground-lift switch is not activated. As I said above, the ‘Direct Thru 1’ output is intended to connect with the source of
- 7/12/2018 · This very problem may be why the BBC “practice” recommends using capacitor microphone power supplies near the microphone with the implication that a single cord from the microphone to the supply be employed as opposed to running the phantom power through all the wiring and patch points which might be between the “stage” and the console.
- For current source, these inductors from transformers are typically connected in parallel, the property of inductors in parallel are to allow maximum frequency to pass through while attenuating low frequencies.
