OPAMPs » Information

The quality of the Operational Amplifier (OPAMP) influences analog sound quality, because OPAMPs amplify the analog signal in your soundcard. With a higher quality OPAMP, the signal is transferred with less loss and distortion.

An OPAMP is a DC-coupled high-gain electronic voltage amplifier. It has "differential Inputs" and usually a single output. In its ordinary usage, the output of the op-amp is controlled by negative feedback. Because of the amplifier’s high gain, the negative feedback primarily determines the output voltage for any given input.

Purpose

Opamp AD797AR The purpose of the OPAMP upgrade is to provide the highest-quality audio to Auzen customers.

All Auzen soundcards support swappable OPAMP sockets, allowing customers to upgrade to higher quality OPAMPs. We have designed custom DIP type adaptors to increase number of OPAMPs compatible with Auzen soundcards.
