These Pre-Amplifiers are specifically designed to operate in conjunction with the NL820A Isolator.
The NL822 and NL824 Pre-Amplifiers are specifically designed to operate in conjunction with the NL820A Isolator. Their small size, low noise, and high impedance differential inputs make them particularly suitable for use as head stage amplifiers close to the preparation.
