What happened to the Proteus?

I was looking for “Quick Look at the Proteus” so that I could provide a link to someone earlier today. I was sure I had done one, but apparently not.

I’m going to be lazy with this review and simply say that it is exactly as described on the MindPlace website… http://www.mindplace.com/MindPlace-Proteus-Light-Meditation-Machine/dp/B005NDED02

The Proteus falls neatly between the Sirius (single colour AS decoder, white standard with non-alterable internal sessions and music synchronising ColorPulse) and the Procyon (RGB tricolour, programmable internal sessions). The Proteus is a bicolour (standard red/green, with other colour combinations available). A comparison chart can be found here… http://www.mindplacesupport.com/content.php?151-Product-Features-Matrix

The 50 internal sessions are editable and new ones can be created with the Session Editor. You can download it to have a look… http://www.mindplacesupport.com/content.php?117-Proteus-Software

You can download the documentation… http://www.mindplacesupport.com/content.php?118-Proteus-Documentation

My personal opinions..

It is a more “pure” red/green AudioStrobe decoder than the Procyon. This is not necessarily a good thing – the Procyon has two AS modes (analog and digital) and several controls for colour mapping, brightness and threshold accessible via the Editor. The Proteus can be considered a “reference machine” – one suitable for verifying that AS encoded sessions for commercial distribution look right on any AS decoder.

The audio synthesis is more sophisticated than the Procyon’s – if the character of the audio is more important to you than three-colour visuals, the Proteus is the better choice. This is not significant if you’re using AudioStrobe as opposed to internal sessions – the audio then is fed via an auxilliar input, as with the Sirius or Procyon rather than utilising the interanl synthsiser.

The Session Editor is rather more difficult to understand than the Procyon’s. The light control is simpler but the audio synthesis has many more options. The Session Editor is well documented but trial and error is the only way to really appreciate what some of the settings really do.

The Proteus is a good machine in the very tidy package common to all the current MindPlace machines. The MindPlace Ganzframes are excellent – comfortable, robust and bright.

Based on price/featureset ratio it is unmatched.

    Hi Craig!

    My first experience with light-sound-machines was the proteus. Now I have the procyon. They’re both great devices, but I tend to not use them that much because I need to actually sit/lie down and “do” the relaxation.

    Anyway, the laxman is intriguing because you can apparently keep your eyes open while using them. Have you ever used the laxman while reading a book, studying or anything similar? The only reason for me to get the laxman would be for the eyes open experience. I’m using avs for self-development, not for entertainment.

    Thanks for sober thoughts on avs by the way! 😀

      Hi Vid,

      Thanks for the kind words 🙂

      The Laxman uses fully enclosed goggles. The ideal combo for reading/studying in conjunction with visual stimulation would be the Proteus with a pair of the see-through glasses with the LEDs arranged around the perimeter previously available from TransparentCorp. See my post… https://craigtavs.wordpress.com/2009/08/02/glasses-maketh-the-machine/ . I have found a supplier of the glasses here… http://www.avstim.com/purchase/accessories.html . White or blue would be fine – blue is a stronger peripheral stimulus, white will be less distracting. Proteus study sessions, a simple continuous SMR/beta with the Proteus User mode or a study session using AudioStrobe from Neuroprogrammer or Mind Workstation would work well.

    Hi Craig,

    Good to see you back posting on AVS. Quick question, regarding the Proteus, have you experienced any type of background humm when the unit is turned on?

    Thanks for your assistance.

      Hi Jim,

      It’s good to be back anf great to hear from you.

      Certainly no hum that I have noticed. It’s probably the best behaved unit I’ve used. I’d be looking to the batteries – none of the MindPlace units are very tolerant of low voltage (and I pick out these units because they are the only replaceable battery units I’ve used enough to notice battery issues). If you’re using it with a power adapter while plugged into the audio output of a mains supplied computer that can produce ground loops – the Procyon is notorious for hum when using USB power from a computer while also using audio from that computer.

    Mindmodulations.com is where I bought my two maschines, first the proteus, then the procyon. I am happy with them. Just wish the connector on the procyon was better!
