Hi,
A actually own a 2B since 2 years. I've seen on forums peoples complaining about feeling produced by using audio on a 2B.
Is there really big difference between 2b and et 232 or 312b on audio processing ?
Does anyone experimented theses power boxes ?

Thanks.

It depends who you ask. They are completely different units, with different design ideas as well as different hardware. Its a bit like asking why rock music sounds different when played with a violin... because it does!!

You must mean Reddit. A couple of pretend 'experts' on there seem to hate the 2B but know nothing about it. I have both the 2B and the ET312 and always prefer the 2B's audio input because it is more reliable and easier to control. Otherwise there is not a huge amount of difference in 'feel'.

The Erostek ET312 has three audio modes (or 'Maps') but in truth only 'Audio 3' works well with stimfiles. 'Audio 2' can just about be used with music and 'Audio 1' is completely useless.
The ET232 is an archaic, older mono box that cannot even handle audio stimfiles properly.

I also have a 2B, ET and several home made boxes with varying technology.

The 2B is very different to all of the others, it is a nice unit for sure but for me there is an issue. The 2B doesnt faithfully reproduce on the output what is applied to the input. This can be and is a good thing if youre trying stim to music tracks etc but it's a hinderance when using a bespoke stim file. The DSP masks some of the finer detail therefore changing the experience completely, lots of detail has gone missing in action. The other boxes I have do follow the audio input accurately, this can lead to some painful results! it does exactly what the stim file tells it to do.
Is the 2B the best? It is very good all rounder, it does help you avoid surprises but sometimes, surprises are a desirable aspect. If you dont have experience of other boxes, get a 2B, you wont be disappointed.

I agree your point and I have the same perception.
And I have a question for admin : why not implement (with a new mode) a classic stereo mode without DSP to have the same feeling than other boxes ? Is it a technical impossibility or a desire not to do so ?

I think there is a later version of the firmware that has exactly that. I havent tried to update mine and have put it up for sale.

With the current hardware it's not possible. And all the other commercial boxes do actually have signal processing involved, and we all use different driver hardware as well.

Yes, I've seen It on Reddit,

Thanks a lot for all yours answers and feedback.

Doing a direct comparison between the Erostek and the 2B using Electron to drive it, the ET unit certainly follows the input much better than the 2B. For example set some very short pain pulse 0.3 sec with a short gap and fire 20 of them off. With ET you feel them (15% extra amplitude) the 2B you dont no matter where the adjust point is. I guess this is the design ethos of the 2B to protect the user and refine the output when music sources are used.
I'm very surprised that the DSP cant be set to no effect and follow the input accurately but I have no experience of the internals of the 2B only my own boxes.

Hello

I sincerely believe that the ET312 is much better materially than the 2B, if only the possibility of controlling the audio and the data at the same time.
I appreciate its fine control and measured as the audio input setting and the progressiveness of the output volume on ET312.
But the lack of an official program worthy of the name makes me choose 2B for remote control.
Locally I like to have control with the mouse with the 2.
