Title: Phantom Power on Stereo Mics
Post by: hasseroeder on October 29, 2010, 11:17:00 AM
Hi Folks,
I want to use a Stereomic (Rode NT4, BD MCE 82) on the R44.
As the R44 provides a dedicated Phantom-Power switch for each channel separately I am not shure if to switch on P48 on both channels the MIC is plugged in or if P48 on one channel only may be ok.

Thanks

both channels. power is typically applied to the capsules separately.

Yeah since its two channels you'll need to power them both. Pretty sure the NT4 can be powered by a single battery but as the 9v starts to drain you may hear a decline in quality/sensitivity.

With professional stereo condenser microphones it is generally necessary to power both channels. If you power only one channel, generally only that one channel will work--or in a few cases the entire microphone will operate poorly or not at all. With professional stereo microphones it's more common for the two channels to have separate amplifiers and powering, so that the one unit can be used as a dual-mono microphone ("a backup for itself").

With semi-pro and consumer microphones there is more variation (standards are respected less, or in some cases don't exist), but I've never heard of any stereo condenser microphone that should not be powered in both channels, i.e. for which you'd need specifically to avoid powering both channels.

--best regards

Shure VP88 requires P48 for both capsules mid and side.

yeah, the AT4050ST is the same way.  Both channels must be powered, even if you only want to use one channel...
