Re: Tetra Mic from Core Sound
There is an extensive discussion about the Tetra Mic (including participation from Len Moskowitz from Core Sound) over on GearSlutz

Re: Tetra Mic from Core Sound
Basically a copy of the design of the (calrec) soundfield mic: SoundField: The Company
So it should give similar results but at a lot lower cost !

And there is the new "Brahma" coming soon, which will be even cheaper - looks interesting.

Re: Tetra Mic from Core Sound
All condenser mic capsules (externally charged AND electret) are "unbalanced" by nature.
And some of the highest-regarded microphones on the planet are electret (e.g. DPA) Now it is quite possible (probable?) that the Tetra capsules and circuitry are of lower quality than the ones Calrec uses, but that is likely the case with most any kind of product that is available in several price ranges. |

An RF condenser mic. *is* balanced by nature. Although an AF condenser is an unbalanced capsule, it is balanced inside the housing of the microphone and exits the microphone as a fully balanced signal. The Tetramike exits the microphone on an unbalanced cable and is, as far as I am aware, only gets balanced at the XLRs at the end of the cable. Oh - Calrec have had no involvement with the Soundfield microphone for decades - they sold it to AMS who then sold it to Ken Giles (Soundfield) who retired last year and sold the company to TSL in Marlow. The Soundfield capsules are OEM supplied by MBHO in Germany, who have a quality equivalent to that of Schoeps.

"T]he Tetramike exits the microphone on an unbalanced cable and is, as far as I am aware, only gets balanced at the XLRs at the end of the cable."
This is the case for most lavaliere mics as well. |

It's only consumer microphones and electret tie microphones & headmics that run unbalanced down a cable. Running unbalanced down a cable increases the risk of RF interference, especially when the cable length gets close to the frequency of the RF interference.

Re: Tetra Mic from Core Sound
That's what I was stating. "electret tie microphones (aka, lavalieres) & headmics"
Furthermore, most lavs that have 3 wires, the 'third' wire is for bias current (power).. from a transmitter, in-line battery or XLR Phantom Power adapter. |

And some "professional microphones" do not have true differential-balanced output, but are actually single-ended and are just "impedance balanced" with a 5-cent resistor. Quote:
