What EEG amplifier do you use?

We use the NeuroField Q21. The Q21 is a state of the art signal processing EEG amplifier. Designed from the ground up for ease of use and flexibility. The Q21 is a 19 channel EEG amplifier with a low noise floor of 0.25 μV peak to peak from 0.1 to 10.0Hz, meaning that you can record brain wave data without worrying about noise contamination. On top of our low-noise design, the Q21 is a non-multiplexed, multi-channel readout amp, minimizing slew for the most accurate whole brain imaging, and giving you the exact readout of your EEG recordings, with no loss of data or smoothing. The Q21 is FDA 510K cleared as an EEG device.
