Estim Dual Channel Videos

[zebbg69]

The DC conversion method is just giving you the A-B difference in a single channel so you don't need a third conductor. In other words, it's the same as connecting for tri-phase but only attaching A and B to your body and not attaching the common to your body. The other polarity DC conversion is A+B which is like making the common out of the red of one channel and the black of the other, then likewise not putting the common on your body.

The reason dual channel feels more gentle is that the "A-B" and "A+B" are not referenced to each other, so they actually float with respect to each other as the signal changes. It's like if you are straddling two skateboards and it's very bumpy as they push your feet in different ways, then you put shock absorbers on one or both, and that takes up some of the pressure. The shock absorbers are the resistances in your body between each combination of electrodes. If you attach the common to yourself along with also that A-B and A+B, that is like taking away the shock absorbers, because now those voltages are rigidly referenced to the same frame, and every little wiggle forces current into your body.

In plain tri-phase, you feel A+B at the common and mostly A-B between the A & B (there's actually another effect that depends on relative resistances between A & B versus A to common and B to common, but ignoring that for this). So dual channel is giving you a similar feeling but without that extra effect and also with the gentleness from not having that common attached.

BTW, LondonGent, thanks for your clever method of converting tri-phase to dual channel!

Is it possible for you to repost this audio file? I've lost it when my SD Card went kaput along with my mp3 player.

Thanks so much.

LondonGent this was awasome. I love the new dual channel estim track for Cock Hero Akimbo.
The only that I miss was the freestyle estim. It felt to long breaks without the freestyle.
And I have also made another long run from some part of this stolen from you sorry.

This is a 2 hour estim file that I have try out and it gave me the longest orgasms without ejaculating.
After about 1 hour and 20 minutes in I have an orgasms that run allmost ½ hour. Or that was what it felt.

You can use it on any favorite Video but it has to be at least 2 hour long.
I have use this one Melt [Supermassive 2021] that is over 3 hour long.

Thanks, LondonGent for posting these very stimulating instructions.
But I have to set the levels a little bit lower for the strokes B/R.

from the thread context, I don't think so. puste made a different one, not specifically for Akimbo.

I'm curious why so many are saying they prefer dual-channel files. Can anyone explain what they like about them that they don't (usually) get from tri-phase files?

I don't "prefer" dual channel per se, but I find triphase very finicky (ET312, Audio 3). The volume settings on each channel are very sensitive, making a short step from "meh" to "too intense". Typically, I need to raise the volume on one channel so that the signal is fairly constant, then the other channel has to be very low. I believe this is due to signals overlapping, maybe at certain frequencies or volume output from the source. The intensity unexpectedly "spikes" at the common.

I tried different electrode placements, it just changes where the spikes are felt, doesn't make them any more comfortable.

As such, dual channel is much less immersion-breaking for me. By the time I get tri-phase into the Goldilocks zone, often the movie is almost done!

Hi, with et312 There are three Power settings, low, medium and high. If you are very sensitive you can try the Low setting!

With ET312 in Audio 3, the common electrode needs to be physically between the two other electrodes (example : left-prostate/common-perineum/right-head, used in PEP series). Audio 2 mode can be used with this electrode placement, effects will softer and smoother, no strong internal sensations.
A placement like common-head/left-balls/right-shaft (used in V91 Sync Hero 1 for example), where the common is not physically between the two other electrodes, is absolutely awful in Audio 3 and not recommanded at all. Some left and right signals will be opposite each other and will be neutralised, so you've got no stimulation at all. Some other signals will add and multiply each other, so you will have a huge, hazardous and very painful stimulation. For this kind of electrode placement, common in an endpoint, always use Audio 2 instead, never Audio 3.

On ET312 :
Audio 1 = the audio input will be delivered as a single mono signal on both channels, even if the audio input is stereo.
Audio 2 = the audio input will be delivered in stereo to channels. Can be used for dual channel programs or triphase ones.
Audio 3 = the audio input will be computed to generate triphase effects with the expected electrode placement (common between the two other electrodes, it is in the user manual). The common wires, according the manufacturer, are black with a white strip (tip of the 3.5 jack). Other wires are full black (sleeve of the 3.5 jack). Don't try to mix a black wire and a black/white wire to a same electrode in Audio 3, it's not recommanded at all.

About the audio output level and the MA level knob with Audio modes :
Some people adjust the audio output level to use MA knob at 9 o'clock. They have their reasons (mostly BDSM related) but you will miss a lot of details on the stimulation, the stimulation amplitude will too short, on/off stim it's not pleasant, and, due the low level of amplification (MA at 9 o'clock), the audio signal will be pretty high, and audio saturation is not a good thing for stimulation too. MA level knob adjustment is pretty difficult too at 9 o'clock.
So, my advice, adjust the audio output level to use MA knob at about 1 or 2 o'clock (at least 12 o'clock and a little more), you will have a better amplitude of stimulation without big on/off surprises, you will feel ramps as expected, no saturation, good effects.
The audio output level depends of the eStim file and its creator. Sometime you have to raise the output volume, sometime you have to lower it, but try to have a MA level knob nearly 1 or 2 o'clock to keep good and detailed stimulation.

I might try putting together a few experiments to see if it's possible to get the best of both worlds...

During the first couple years of stimming, I almost always used triphase-based files. Most triphase files are constant volume in each track and merely rely in phase shifts to only produce stroking effects (but some triphase files are more sophisticated). This gets boring. Because many triphase files run both channels at constant volume, I notice that the numbness after using a triphase file is greater than a stereo file.

A good stereo/dual channel file, Guerlain is a good example, has different types of signals in each channel. The Right channel (anal or balls) is best as a more percussive or vibratory channel with lower frequency. The Left channel (shaft/tip) is a smoother channel which depends more on softer higher frequencies. You have something completely different going on in each channel. Dual channel files permit more liberty to use chords which would otherwise erode the perception of phase shifts.

An easy comparison is Estim Tower (triphase) vs. Estim Hack (stereo). They are best enjoyed in their preferred mode. Some files, like my GLEE series, will happily work in either mode (mostly, as I didn't know what I was doing at the time).

I think dual channel files require more reliable electrode positioning (because you have +1 trode to deal with). What caused me to prefer them was buying several of Joanne's electrodes. The "Heaven and Hell" electrode is good for Left channel, leaving the Right channel for loops, pads, or anal options as mood strikes you.

Good point, I'll try it on Low power.

[BlueM00]

So, my advice, adjust the audio output level to use MA knob at about 1 or 2 o'clock (at least 12 o'clock and a little more), you will have a better amplitude of stimulation without big on/off surprises, you will feel ramps as expected, no saturation, good effects.

I always set MA to 12 o'clock, and adjust the audio source's volume to show steady (but not full-on) lights on both ChA and ChB when somewhere in the middle of the mp3 file. I'll try moving MA closer to 2pm (and presumably lower the source volume slightly).

Sounds to me like you're struggling with one of the issues I've been trying to counter. Your typical triphase file sends double the volume to the common electrode when the two signals are in-phase, which can make that electrode overpoweringly strong. Couple that with whatever weird processing the ET312 is applying in Audio-3 mode and I can see why it could be troublesome.

Try switching to Audio-2 to get rid of the processing and if it's still 'spikey' then increase the size of the common electrode (or even connect two electrodes to the common output). A larger contact area results in a gentler sensation, making it easier to balance the common vs the two regular electrodes.

I have to say moving the MA for me can fundamentally change what I am feeling. On many file 9 or a smidge below can feel great, with smooth define stim, but turn it up and it all gets a bit buzzy and blurry or washed out. Other files 9 or 12 makes almost no difference, and i have hardly ever gone past 12 (although funnily enough last night i used a file where 3 was the only MA setting that was nice
