Mind Gear SLX

The Mind Gear SLX

The Mind Gear SLX light and sound brainwave frequency mind machine was an affordable and effective system for brainwave entrainment, accessing all general brainwave states of consciousness: Beta, Alpha, Theta, Delta and even High Beta (often called Gamma).



With sixteen built-in light and sound brainwave sessions and frequency range from 1Hz to 40Hz, the Mind Gear SLX was very similar to the higher priced Mind Gear PR2x light and sound brain machine, also referred to as psychowalkman.



The SLX produced two sounds including binaural beats, had adjustable pitch control and each session could be lengthened or shortened depending upon how long the user wished to do a specific light and sound session. Priced at $149.95, the Mind Gear SLX was an excellent choice by thousands of mind machine users during the late 1990’s and into the early 2000’s.

InnerQuest IQ – JR Mind Machine

The InnerQuest IQ – JR Mind machine

The InnerQuest IQ jr was one of the finest mind machines ever produced. The late founder of Psych Research, Rob Robinson, worked with Gayland Hurst, Ph.D. and Rayma Ditson-Sommer, Ph.D. to compile fourteen highly effective built-in light and sound brainwave frequency sessions that during the 1990’s proved beneficial to thousands of light and sound mind machine users worldwide.



Though basic in style, at least by today’s standards, the InnerQuest IQ-JR featured two types of brainwave frequency stimulation with the ability to ‘hold’ any specific frequency or pattern of frequencies during any given light and sound session, whether those frequencies were in Beta, Alpha, Theta, Delta or any combination thereof.



The InnerQuest IQ-JR was a complete system that came with red LED light frames, high quality headphones that were soft, comfortable and completely blocked out all outside noise, ac adapter and an owners manual that was incredibly easy to understand. If Psych Research / InnerQuest was still around today there is no question that the IQ-JR would still be a top-selling mind machine.


Synetic Systems Mastermind

Synetic Systems Mastermind

Mindplace, the manufacturer that produces the Proteus, Procyon and Kasina Mind Media mind machines, was formerly known as Synetic Systems. During that period, they produced a beneficial little mind machine (also known as brain machine or psychowalkman) called the Mastermind.


The Mastermind was a pretty cool little system, featuring a unique new keyboard that allowed the user to chose the type of brainwave stimulation they wanted; the type of audio beats, for example binaural beats, for the light and sound frequency generation; and the length of time they wanted the session to last. Synetic Systems streamlined the selection process, making the whole thing easier to use.


On top of all those features they offered something else new: Polysync technology. By using a specially encoded cassette tape which in the first five to ten seconds of the tape had a series of beeps and tones which were actually instructions for the Mastermind to synchronize the pulsed lights and audio beats to the music on the cassette.

Polysync was touted as extra special, making the Mastermind the only light and sound mind machine you would ever need because all you would have to purchase in the future would be Polysync cassette tapes.

As great an idea as this was, unfortunately cassette tapes faded from the landscape as CDs became the popular format. And one word can best describe why the Mastermind was discontinued: Audiostrobe.

Mindplace Orion

The Orion by Mindplace was an inexpensive light and sound mind machine that contained brainwave frequency sessions targeting all four general states of consciousness: Beta, Alpha, Theta and Delta. Here is a brochure from 1996 first introducing the Orion mind machine to the general public:


The back of the brochure is still a great read, detailing the advantages of using this great little brain machine, also known as a psychowalkman…


A few years after the Orion’s introduction, upgrades were made and this Mindplace light and sound machine became known as the Sirius light and sound instrument. But after a few more years the Orion / Sirius was retired, mainly due to the increased popularity of the Mindplace Proteus, Procyon and Kasina Mind Media mindmachines.









Mind Gear PR2-x

The Mind Gear PR2-x was a very cool mind machine, both effective and beneficial. In fact, the built-in sessions proved so effective that this system’s predecessor – the Bluetooth MindLightz – contains many of the same sessions.



A lot has changed, obviously, as now there are no more wires to contend with. During the PR2-x’s heyday, the light frames rocked with colorful visuals and the headphones weren’t the cheap type common to many other light and sound mind machines.




Take a trip back in time by enlarging the above image and read what last century’s brain machines, also known as psychowalkman, specifically the PR2-x offered light and sound enthusiasts as the latest in modern technology.


The Light and Sound Museum

The Light and Sound Museum is a place for you to see user guides and images of light and sound machines that are no longer made.

Light and sound mindmachines typically last for years, like my IQ-III and Pro-S from InnerQuest. But they can be rendered useless if the session list disappears.

Here is where you can find a replacement user guide or session list for several of the older mind machines.

Enjoy! And I hope you find what you are looking for…
