AM-3500 Extracellular Amplifier

The AM-3500 moves you out of the past and into the future of multiple channel amplifiers.   It gives you "true differential" amplification on each of the 16 channels.   And is designed to interface directly to the electrode without a headstage.
The amplifier's powerful features can be accessed via software or accessed at the device using an easy-to-use touch panel interface.   The AM-3500 has all of the features you could possibly need for extracellular recording.
See also the AM-3600 for a similar amp that is compatible with various headstages.
AM-3500 Key Features
- 16 independent high gain, low noise channels
- Select from either a common reference or "true" differential recording with a separate reference on each channel
- A wide range of high pass, low pass, and notch filters
- Pass stimulation current to any or all channels
- Hardware stimulus blanking
- Built-In output monitors and calibration signals
- Control via touch screen or compatible software program
- Store amplifier settings in the amplifier or on the computer
- Link multiple amplifiers together for higher channel counts (32, 64, 128 etc.)
- Optional software control directly from DataWave SciWorks
- Can be rack mounted
