* Using existing EEG files for teaching purposes with the BrainVision Analyzer Education or using the amplifier installed in the lab for training purposes, is the common procedure for out of the lab training sessions. We are offering the FirstAmp in combination with the Analyzer Education at a special low price. But it doesn‘t stop here! When you order a FirstAmp we will upgrade the number of licenses for your Analyzer Education to a total of 30, thus beating class size even in the most crowded environments! ** Versatility is the most distinctive feature of the Brain-Vision V-Amp. Favorably priced, the V-Amp is a valuable supplementation even for well-equipped laboratories. Biofeedback experiments, teaching courses as well as low budget projects will profit from the package including full BrainVision Recorder and Analyzer licenses shipped in a handy carrying box.
