Medusa4Z Amplifier

The Medusa4Z Amplifier is a low noise, 4-channel amplifier for evoked neural responses. The device is a drop-in replacement for your existing ABR amplifier with a lower noise floor and greater dynamic range.

With an ultra-low noise and 24-bit, high-fidelity digitization circuit developed for our high channel count PZ amplifiers, the Medusa4Z amplifier will get you to threshold faster and with less distortion than ever before.
