JWLABS MODEL A4.0 Rife Machine
No longer in Production – Call us for availability of Pre-Owned Units

The Model A4.0 contains a comprehensive library of expertly tuned frequency sessions. The tuning is extraordinarily refined and the range of frequencies spans the entire breadth of the lower audio range. Typically, from about 2hz to 10,000hz – though sometimes we tune beyond 10,000hz.
With the Model A4 touch-screen Rife Machine, we have removed any chance of missing the correct frequencies, eliminated the need for constant tuning, and solved the practical problems that made the old manual designs difficult for all but an expert.
Our innovative Touch screen menu makes the JWLABS Model A4 Rife Machine the most user-friendly Rife machine on the market!
