| State-of-the-art amplifiers that fit your needs |
| With asa-lab ERP you can select the best amplifier for your application. Whether you are looking for interested in cognitive ERPs or short-latency EP components, ANT has the amplifier that fits your needs! |
Full-band DC amplifiers The high-density amplifiers let you record data up to 128 channels. Connect the amplifier to the USB of your notebook for a portable system. High-density amplifiers can be cascased to increase the numbers of channels. Hence two 128-channels amplifiers can be combined to 256 channels. This in combination with our innovative WaveGuard cap system provides with all the power you need for those studies.A high-speed amplifier is available for those cases were you need the high sampling rate. The amplifiers can record up to 10kHz for 32 channels and up to 5kHz for 64 channels. In case you need an ambulatory device or want to record wireless, our Bluetooth amplifier is the solution. Allthough the number of channels is limited to a maximum of 16 different type of electrode inputs (EEG, bipolar for EMG, ECG and auxiliar for respiration, movement sensors etc.) are available making this amplifier a true polygraphic recorder. The asa-lab light amplifier is the most optimal solution for your students! This low-cost amplifiers has all the inputs you need for a basic EEG/ERP system. It has 24 channels EEG, 4 bipolar and 4 auxiliary inputs. The asa-lab light amplifier can be combined with the asa recording and signal analysis package. It is the most affordable system available at this moment. | ||

asa-lab Lite amplifier Number of channels 32 total (24 EEG plus 4 bipolar and 4 auxiliary channels) Sampling frequency maximum 1024 Hz Non-shielded touchproof inputs Resolution 22 bit, 71.5 nV per bit Input impedance > 10^12 Ohm Noise < 1.5 microVpp (at 100 Hz) CMRR > 110 dB Trigger input 8-bits TTL Connection to PC Fiber optic to USB2 |  |
Active-noise cancellation The electrode inputs are shielded with the electrode signal itself (active shielding). This ensures a disturbance free measurement and has the effect that 50/60Hz interference and artifacts due to movement of cables are reduced to a minimum. | ||

Bipolar and auxiliary (high level) inputs Bipolar inputs are available on the high-density type amplifiers and allow the recording of EMG, EOG, ECG etc. using a true hardwired bipolar channels. The bipolar inputs are actively shielded.Auxiliary inputs can be used to connect active sensors like respiration bands, GSR, nasal flow sensors, pH sensors etc. to the amplifier. Each auxiliary channel has a 5-pin connector. Signals on this connector are power (+5V,-5V), ground, and +signal and -signal input (actively shielded). | ||

fMRI, MEG and TMS compatibility The asa-lab high-definition amplifiers are fMRI, MEG and TMS compatible. A non-magnetic battery pack powers the amplifiers during acquisition (up to 8 hours). MEG/EEG or fMRI/EEG acquisition is carried out using a special designed non-magnetic cap. | ||

Cascade amplifiers for more channels! Both high-density and high-speed amplifiers can be cascaded for those cases when you need more channels. Cascading of amplifiers is achieved by connected two amplifiers of the same type to one computer. The asa recording software takes care of the rest! |  | ||
