Description
The ElectraStim SensaVox (model EM140) has been part of ElectraStim’s range since 2005, which puts it among the longest-running dual-channel e-stim power boxes still sold today rather than a novelty that quietly disappeared. It’s built for players who want more control over stimulation than a single intensity dial can offer: run it from the mains or a 9V battery, work the tactile twist-dial controls by hand, or hand control to sound itself through the included microphone or a line-in audio lead. Feed it music or speak into the mic and the unit translates volume into intensity as it plays, layered on top of nine built-in pattern programs you can still shape by hand.
Two fully independent channels, each with its own twist-dial, mean you can run different power levels on each side at once — level 99 on one channel, level 20 on the other, or anywhere between. Between them the two channels drive up to 4 uni-polar or 2 bi-polar electrodes at a time, so the unit suits solo play across multiple electrodes or two people sharing one box. SensaVox is the control unit only — it does not include any electrodes or pads. You’ll need at least one bi-polar (or two uni-polar) ElectraStim-compatible electrode before you can use it.
Electro-stimulation carries real medical contraindications that apply no matter how the intensity dial is set. Do not use SensaVox if you have a pacemaker or other implanted electronic cardiac device, if you have epilepsy, if you have an unstable heart condition, or if you are pregnant. Electrodes should never be placed above the waist or near the heart, never on broken or irritated skin, and every session should start at the lowest intensity level before increasing.
Things to know
- Model: ElectraStim SensaVox EM140 — dual-channel electro-stimulation control unit
- 99 intensity levels per channel, controlled by independent twist dials (over 4 full dial rotations to reach maximum, so power ramps up gradually rather than jumping)
- Two fully independent channels — drive up to 4 uni-polar or 2 bi-polar electrodes at once, each channel individually adjustable
- 9 pre-programmed stimulation patterns (steady, pulsing, alternating, building and climax-style modes), each modifiable for speed and pulse width
- Audio/voice control via the included 3.5mm microphone or a line-in audio cable — stimulation intensity follows the volume of the sound source
- Boost button adds a temporary 25% intensity burst on both channels
- Mains or 9V battery powered, with an automatic power-saving mode on battery (display dims and switches off after 15 seconds of inactivity)
- Built-in safety cut-outs: intensity resets to zero whenever you switch on, change program, or switch into an audio mode, and you can’t raise intensity on a channel that isn’t currently active
- Not for anyone with a pacemaker or other implanted electronic cardiac device, epilepsy, an unstable heart condition, or during pregnancy; keep electrodes below the waist and away from the heart, never on broken or irritated skin, and start at the lowest intensity
- LED intensity/program display; low-battery warning indicator
- This is a control box only — no electrodes are included; at least 1 bi-polar or 2 uni-polar electrodes are required and sold separately
- Not waterproof — this is a mains-capable electronic unit, and moisture is a genuine hazard around it: no showers, baths, sinks, or other wet settings
- 1-year manufacturer warranty (extendable to 3 years with product registration)

Frequently Asked Questions
What is the ElectraStim SensaVox EM140 used for?
The ElectraStim SensaVox EM140 is a dual-channel electro-stimulation control unit that drives up to 4 uni-polar or 2 bi-polar electrodes, controlled by twist dials, 9 built-in pattern programs, or audio input from the included microphone or a line-in cable.
Does the ElectraStim SensaVox EM140 come with electrodes?
The ElectraStim SensaVox EM140 does not include any electrodes or pads — it is a control unit only, and at least one bi-polar (or two uni-polar) ElectraStim-compatible electrode must be bought separately before it can be used.
Who shouldn’t use the ElectraStim SensaVox EM140?
The ElectraStim SensaVox EM140 should not be used by anyone with a pacemaker or other implanted electronic cardiac device, anyone with epilepsy, anyone with an unstable heart condition, or during pregnancy, and its electrodes should never be placed above the waist or near the heart.
