Fethead Boost your Mic 20 db
« on: March 09, 2010, 04:43:56 AM »
Here comes a clever little device 75 Euros.
Gives devices like  Microtrack (with TRS XLR Adapter) Metric Halo 2882 a big boost in Noisefreeer Recordings. I think ist better then the other similar device from Rode

Not sure I can see any application for tapers?

A lot of us are using -20pads on preamps - so adding 20 doesnt seem to make sense.

Sounds like it would do little but guarantee brickwall distortion on most devices.

Ok thats an argument I made sometimeago Ambient Recordings with Microtrack where it would give  better results.

The FetHead is more for ribbons and dynamics. I use a pair all the time with my stereo ribbon and other ribbons, but for classical music.

With Ribbons it is very much the same  with condensors, if the source is not loud and the amp has then less noise.

I think you are mistaken. The FetHead (and the Rode one) can't even be used with a condenser that needs phantom power, unless you put another phantom power supply in front of the FetHead. Then you are double-amplifying it, which is probably completely unnecessary.

A passive ribbon, on the other hand, might need massive amounts of gain (60db+), and some preamps are noisy at such high gain. The FetHead gives an excellent alternative to give an extra 20db of gain before hitting the primary preamp.

The FetHead is phantom powered, making it a perfect inline solution for ribbons, dynamics, and tube mics if you wanted to. Using it with condensers is much more troublesome and not really its intended use.

There is another model that passes phantom power (which has nothing really to do with "amplification", just turns the mic "on")

Hmm I didn't know that.

I personally still don't see the point, unless you have a very weak preamp.

...or you have Metric Halo 2282 and not want to upgrade to  the ULN 8

Can you explain that? I use it with a stereo ribbon all the time usually with 30-50ft cable runs. I always put them right at the mic but I never really thought about it. If it's better to put it at the preamp then I will.

Funny you say that, because I have had two instances of a radio station coming through the mic. This was when using the FetHead at the mic. Should I have switched it to the preamp side?

I will ask Tritonaudio about this, also the Outputimpedance and the current used,  think read 3 mA Gentlemen here the answer:
Your questions about the FetHead Phantom, would you like to know more, feel free to ask:)

Output impedance : 600 Ohm

Powerconsum:  1.5 mA (it is on a diet compared to a normal FetHead)

HF sensivity, some peple can here Radiostations  with this item:

All types of FetHead are NOT sensitive to RF and very well shielded. What
could happen is the following: If the microphone attached to the FetHead
is not properly grounded it could become sensitive to RF. In most cases
this is fixed by restoring the grounding of the microphone body. The
microphone body is usually grounded by a screw which secures the xlr
connector and which also electrically connects the microphone body to pin
1 of the xlr connector. Repeatedly sticking and pulling out  the
microphone cable from the microphone can loosen the screw which makes the
microphone less shielded. Bad microphone cables and worn out xlr
connectors can also have influence.

Hope this helps :)
best regards,

Peter-Paul (TritonAudio)
