Why?
A Brain machine session for a group of people simultaneous is very popular at music festivals. This can function as a CHILL OUT for the audience or, in opposite, to sweep them up. Also in a night club and discotheque this is popular. The BWL X22h is a typical model to be used at a promotional stand on a music festival where a large audience is available and they can join a session in a group of 14 people - laying relaxed in a chair for some minutes (5 to 15 minutes). Also on Computer fairs this has proven its success because many like to do something special besides watching all that boring computer stuff. The BWL X22h can be used together with the BWL software and a PC or can be interfaced to any other Brain Machine.

The Brain Wave Laboratory had many successes in Holland on Computers fairs, Disco's and alternative health institutes with expanders up to 50 people. Recently, as Brain Machine became popular for a large audience, The BWL expanders of Marc Marc Amsterdam nowadays find their way again to festivals, clubs, alternative health care centers and Disco's. And not at last because we also though about the entertainment value of a session with groups. We like to advise you not only on the technical data for the best suitable interface but also on how to present it successfully to the audience.
Besides the existing sessions - from which some of them do have a great festival entertainment quality - we can create any session based on your ideas.

The Brain Wave Lab configuration with a PC involved give you a very high standard and entertaining Brain Machine which goes beyond the possibilities of its competitors. And, when we consider the costs, it also is very competitive.

Functional Description:
This description will handle about the BWL X22 module but, also - in its essence - is valid for any BWL expander.
Realize that the BWL expanders not only can interface with the BWL computer software but also can be designed to expand any Brain Machine you would like to use. We simple adapt to your interface application (brain machine) and type of goggles.

On stage, there is a 'mother' application available. This either is the BWL software (which is for free) and PC computer or any other brain machine. This 'Mother' connects to the BWL X22 interface to expand to 21 users (plus a master controller when required). All users have their own set of goggles and headphones. A session starts and the audience is experiencing for a certain amount of time (5 to 15 minutes) an entertaining Brain Machine Session.

The BWL X22 Interface gives you the opportunity to interface both audio and LED signals to be expanded to 21+1 user. The LED controlling signals can be interfaced digitally or analog - depending on your requirements or interfacing with your requested brain machine. As a great extra, the BWL X22 also has a so called 'Thinkman' module included. With the Thinkman you can convert any music to a Brain Machine session and/or mix it with the original Brain Machine source. Also, an extra sound input lets you mix auxilary sounds to the total mix.

The editor/operator has its own set possibly to be connected to the interface and the 21 users (or less) are connected to the brain machine through the so called division boxes. The BWL X22 has 6 connections for both goggles and headphones to 3 division boxes which can be laid out on location. Each box is connected with two XLR cable to the interface (LED and Phones). The cable are 12 Mtr long and thus may cover a wide setup on stage (they can be delivered at any length).
