Best DC Coupled Audio Interfaces in 2024 Reviews

DC-coupled audio interfaces are a type of audio interface that can pass DC voltage through their outputs. This makes them ideal for use with modular synthesizers and other electronic instruments, as it allows for control voltages to be sent from the interface to the instrument.

These interfaces are also becoming increasingly popular among musicians who want to use their computers to control analog synthesizers and other gear. They can also be used for other creative applications, such as sound design and experimental music.

Top Features to look at while buying

  • DC Coupled Ports: The most important feature to look for in a DC-coupled audio interface is that it has DC-coupled inputs and outputs. This will ensure that you can use the interface with your modular synthesizer or other electronic instruments that produce DC signals.
  • Audio Resolution: Audio resolution is the number of bits and the sample rate that the audio interface can record and playback. Higher audio resolution will result in better sound quality, but it will also require more processing power from your computer. Most DC-coupled audio interfaces have an audio resolution of 24-bit, 96kHz or higher. This is a good starting point for most users.

In this article, we will discuss some of the best DC-coupled audio interfaces on the market, and discuss the key features to look for when choosing one and also provided a “Buying Guide” to help you make the best decision for your needs.
