3.5mm Mono Jack Wiring Question

[estim_si]

Don’t forget our E-Stim Systems Triphase cable set comes with adaptors for 2mm and 4mm so you can mix and match

Stimaddict you are a true legend in this area and im a newbie so have mercy.

Im considering if i need to buy some banana jacks for my stereostim.
If theres no difference in what two wires you join as the common i dont need to.

But i think there will be.
I get that its AC and the + and - alternate.
So lets think of it as two AA batteries the two transformers
Lets think of channel A playing 800hz and B also 800 hz
The two sine waves are in sync.
So its like the two AA batteries are turning 800 times a second.
If you connect black with black then its like connecting the two - sides of the batteries as common
So trode A will be 1.5v with the common so will trode B. Between the A and B trodes 0 volts

However if you connect red with black then its like connecting the - to the + of the batteries like in an old torch. Between the common and A trode there will be 1.5v ,, common and trode B again 1.5v ,,between trode A and B there will be 3 volts.

Since its ac when the cycle goes under its like both batteries turning 180degrees so no change just polarities change. So in black on black setup again no voltage between the A and B trode.
But 3v if red and black as common.

Now when the stereostim goes in to different voltages say left side 20v right side 40v and you have a black on black common then between the trodes youll actually have a voltage difference of 20v

If you do red with black common the between the A and B trode there will be 60v

So its true that some action will take place between the A and B trodes but completely different scenarios.
What will be better will depend on placement of electrodes sensitivity and the full list.
But it will be different so ill have to buy them banana jacks to see what works better.

I guess if you have the common in the prostate A on penis and B under the balls then since A is a more sensitive spot and A and B are close might be better to have less voltage between A and B

If common is on penis might be a good idea to have red and black common.
Cant tell really will need to swal and experiment
Whatcha think.

Hi - TriPhase, or a 3-Electrode Setup, is simply just this:

Stim boxes use a kind of alternating current waveform so there is NO positive or negative. For the "Common" electrode you can connect two red cables, two blacks, or one red and one black.

As a rule of thumb the "Common" electrode should be where you want the most stimulation. For me that's usually the glans, but if you like ball stimming better then position the common trode there. The common can be ANY electrode - a pad, a Conductive Rubber loop, a metal cock ring or a butt plug.

*Q) "What exactly is TriPhase?"


*A) This gets a bit technical. We all, perhaps incorrectly, refer to TRIPHASE when we really mean a 3-ELECTRODE SETUP. *TRUE* Triphase is something different.

A 3-electrode setup will produce two signals, one per channel. It drives current and sensation to the 'Common' electrode which can be delightful and the interaction between the two signals can feel enhanced.

*TRUE* TriPhase sensations involve the perception of a distinct third 'phantom' signal moving between the other two, achieved by having two phasing signals active on the output simultaneously. In stimming terms "true triphase" is a perceived sensory illusion working in a similar way to listening to Binaural Beat tones through headphones.

There is only one commercial stim box with an inbuilt routine capable of producing the true TriPhase effect, the Erostek ET312. However both the ET312 and the E-Stim Systems 2B can produce true TriPhase effects via STEREO audio input using certain stimfiles.

TBH I've never found 'true triphase' to be as good as the purists go on about, so personally I don't think it's worth getting too hung up about.

Yeah this often came up on SmartStim. I've experimented but I'm damned if I can tell any difference. "True" Triphase is itself a sensory illusion, so maybe we perceive things differently according to our expectations?

I have played around with triphase and there certainly can be a third signal, no illusions it does exist. I agree that in the main with audio files, little difference can be felt no matter how you connect it up.
My experiment as such had me wired up initially with the two blacks or screens as common. |Feeding a sinewave into a stereostim box (no DSP like 2B), with the sinewaves in phase, no third channel could be felt. With one channel fed with a sine wave equal but opposite the third channel made itself known. Changing the phase angle of the channel increased and decrease at different times all 3 channels.
inverting one channel is the same as connecting a red and a black as common, the output between the channels if theyre in phase doubles the voltage and does make a huge difference but only with the signals that have a phase relationship. Setting one of the channels 0.05 Hz different caused a steady phase difference between the channels and really demonstrated the potential of triphase.
If an audio file was authored with a true understanding of triphase outputs there could be some amazing sensations. The difficulty is for the author and the subject will have different sensations based on their nervous system, electrodes and placement etc, consistency would be nigh on impossible.
Every time Ive tried triphase other than in the lab conditions above, I've found it to be disappointingly prickly / harsh / too low at times.

I have several tens pads that i cut the leads off of and make my own adapters sure save on money
