Connecting an AUX Cord to a USB: A Comprehensive Guide

Introduction

The question of how to connect an AUX cord to a USB port might seem basic, but given the different signal types, it requires a bit of understanding. In this guide, we will explore the methods and necessary equipment for making this connection. Whether you want to get analog audio into a device with a USB port or vice versa, we will provide you with the information and steps you need.

Understanding the Signal Types

To start, it is important to understand that the signal on the AUX cable is analog, while the signal on a USB port is digital. Therefore, a direct connection is impossible in most cases. However, with the right adapter or converter, you can achieve the desired connection.

Connecting Analog Audio to a USB Port

If you want to capture analog audio using a USB port, you need an audio capture device. This is particularly useful for recording audio from a music source or other analog devices. The simplest and most cost-effective solution is to use a USB DAC (Digital-Analog Converter).

For recording purposes, you might also need a USB sound card, which can handle both input and output of audio signals. These devices often come with multiple connections, such as 3.5mm analog ports for input and output.

Steps to Connect an AUX to a USB

Option 1: Use a USB DAC

Here is a step-by-step guide on how to connect an AUX cord to a USB port using a USB DAC:

Choose the Right USB DAC: Look for a USB DAC that is compatible with your device and has a 3.5mm or 5.5mm AUX input port. Popular brands include Focusrite, Blackjack, and Numark. Connect the AUX Cable: Plug one end of the AUX cable into the USB DAC's input port. Connect the USB DAC to Your Device: Plug the other end of the USB DAC into your computer or other device with a USB port. Configure Your Device: You might need to install drivers or configure your device settings to ensure that the audio is routed through the USB DAC.

Option 2: Use a USB Sound Card

For devices that require both input and output, a USB sound card is the solution:

Choose the Right USB Sound Card: Select a USB sound card that supports both input and output through 3.5mm ports. Popular options include M-Audio, Presonus, and Behringer. Connect the AUX Cable: Plug the AUX cable into one of the input ports on the USB sound card. Connect the USB Sound Card to Your Device: Plug the USB sound card into your computer or other device. Configure Your Device Settings: Ensure that the audio is set to use the USB sound card for both input and output.

Where to Purchase the Necessary Equipment

A USB DAC or USB sound card can be purchased from various online retailers. Here are a few options:

Amazon: You can find both USB DACs and USB sound cards on Amazon. Popular sellers include HongKongShopy, GearBest, and ShenzhenSeejias. Ebay: Many sellers on eBay offer USB DACs and sound cards. Brands such as Blackjack and Numark are frequently found here.
