Brain Trainer

QDS ExCalibur or Quantum

Make It Clean
The best mass-produced amps produce internal noise of at least .5 microvolts. They use high impedance pre-amps to cover up this noise and bad electrodes or connections. Unfortunately, subtle EEG signals are also blocked. Each QDS amplifier is individually assembled and tuned. Cases, wires, boards and chips are chosen based on an absolute commitment to shipping devices with internal noise readings of ZERO nV. Thus there is no need for excessive input impedances, allowing the most complete EEG signal to pass into the training software.

Make It Fast
The best feedback requires the cleanest, most complete signal. It also requires accurate, fast signal processing. Speed and resolution directly affect feedback to the brain. Bit rate is the width of the highway through which signals travel. Eight or 12-bit amplifier have 8 or 12 lanes. QDS amplifiers carry 16 bits at a time! The baud rate is the speed at which signals travel on that highway. QDS amps speed signals at 57,000/ second--50% faster than the next fastest BioExplorer amplifier. With 16 lanes of traffic, that’s a LOT of data passing each second!

Make A Difference
When experienced trainers switch to a QDS Amp and their clients notice the change, their outcomes change in a session or a few, or they see a difference in the clarity, quality and resolution of the signal, the QDS commitment to a clean, fast signal pays off.

Get electrodes and supplies for your QDS amplifiers. The amplifiers come with two jumpers, each of which can link four (Quantum) or two (ExCalibur) reference inputs together. Thus, each ear can serve as the reference for four/two actives. In order to do linked ear references, you will need to purchase only one jumper.
