Re: [Sursound] Comparison Sennheiser Ambeo mic vs. Rode NT-SF1?

2018-12-14 Thread Jack Reynolds
They are quite different, so it’s hard to say which was better initially. 

The rode has more apparent depth, which is probably due to its lower noise 
floor and higher sensivity, but it’s difficult to tell how much difference the 
A to B filter is making. 

Hence A-Format files might give you a better idea of the original character of 
the capsules. 
We also tested the Zoom H3VR and a few of my prototypes and I was surprised how 
different they all sound

Apparently so.



There has been a report that the encoder introduces unpleasant sonic 
artifacts if the NT-SF1 is in motion during recording. Links to 
recordings made that way were posted on Facebook, and I've heard them.




This report is yet to be duplicated.

I have some recordings made with both microphones, plus a few others. I
will post soon with any luck.

Would raw A-Format be preferable?

The Ambeo uses Sennheiser K-14 if I remember the number correctly. They
work very well. I guess unless you want to use a mic in really hot
conditions like close to incandescent stage lights (where an electret
might lose its charge) or at extremely high SPL (where you might want to
use higher polarization voltage on the diaphragm), there is really no
problem. Haven't used the Sennheiser mic since I tested a prototype
several years ago, but it held up very well. I don't buy this "real 
condenser" lingo.


My subjective experience with the Sennheiser was this:

* slightly worse localisation than the Tetramic
* slightly nicer tone color out-of-the-box than the Tm (but then there's
always EQ and tastes differ)
* significantly quieter than my Tm
* more "neutral" and a bit less "in-your-face" than the ST450 (which
sounds very cinema-y to me)
* much nicer and more professional package than my first-generation Tm,
easier to have confidence in...
* less bulky than a similarly rugged ST450 because no pre-amp box
* lighter on the boom than a ST450, but nothing beats the Tm here (if
you keep the PPAs down at the or on the recorder)

Can't say anything about peak SPL handling, I mostly did street and
nature atmos while testing.

The prototype ate through batteries like crazy due to its phantom 
current requirements. I was told there is a fix coming in later batches 
of the series, don't know what became of it. If you get the chance to 
test one, do run it on batteries and see if it's a problem for your use 
case. This is only really relevant in comparison to the Tm, the ST450 
uses a lot more power due to external preamp and capsule heating.


Best,


Jörn

Re: [Sursound] Comparison Sennheiser Ambeo mic vs. Rode NT-SF1?

2018-12-14 Thread Steven Boardman
Hi Stefan

One can use multiple instances to create as many beamformers as one needs
to upmix or extract. One doesn't need to be constrained to 7.1 or 5.1
positions, as all beamformers can be moved. Although in pairs and a
separate centre channel, which is a pain.
As i mentioned earlier, it good at this, a lot better than the usual
virtual first order mic. As one can suppress the rear lobe. It is
definitely sharper as well.
I can't compare it directly to Harpex as i don't have the full Harpex
version, just the algorithm in Blue Ripples Harpex up mixer. (which i use
all the time)
The Rode plugin is free so try it. I am not sure why, as I think users
would pay for its decording. I am now using it regularly.

Best

Steve

Yes, but the Sennheiser has electret capsules while the Rode is a 
'real' condenser mic. I do agree that electrets have come a long way 
in recent years. Still, I'd like to know how they compare beyond 
their noise level.
