When it comes to immersive audio experiences, surround sound is the gold standard. However, setting up a traditional surround sound system can be a daunting task, requiring multiple speakers, amplifiers, and a receiver. But what if there was a simpler, more affordable way to enjoy surround sound? Can USB be used for surround sound, and if so, how? In this article, we’ll explore the possibilities and limitations of using USB for surround sound.
What is Surround Sound?
Before we dive into the world of USB surround sound, let’s take a step back and understand what surround sound is. Surround sound is an audio technology that envelops the listener in a 360-degree sound field, creating a more immersive and engaging experience. This is achieved by using multiple speakers placed around the room, each producing a distinct audio signal. The most common surround sound configuration is 5.1, which consists of five full-range channels (left and right front, center, left and right rear) and one subwoofer channel.
Traditional Surround Sound Setup
Traditionally, setting up a surround sound system requires a receiver or amplifier that can handle multiple audio channels. This receiver is connected to multiple speakers, each placed in a specific location around the room. The audio signal is then processed and distributed to each speaker using a complex system of cables and connectors. This setup can be expensive, complicated, and limited by the number of available audio channels.
Enter USB: A SIMPLE ALTERNATIVE?
With the rise of digital audio and computer-based entertainment, USB has become a popular interface for connecting audio devices. So, can USB be used for surround sound? The short answer is yes, but with some limitations.
USB Audio Devices
USB audio devices, such as sound cards, audio interfaces, and USB speakers, can process and transmit multiple audio channels over a single connection. This makes it possible to connect a surround sound system to a computer using a single USB cable. However, there are some important considerations to keep in mind.
Channel Limitations
Most USB audio devices are limited to stereo or 2.1 audio channels (left and right speakers, plus a subwoofer). This means that a traditional 5.1 surround sound system cannot be directly connected to a computer using a single USB cable. However, some high-end USB audio devices may support more audio channels, such as 7.1 or even 9.1.
Audio Quality
Another important consideration is audio quality. While USB audio devices can transmit high-quality audio, they may not be able to match the fidelity of a dedicated surround sound system. This is because USB audio devices often use digital signal processing and compression to reduce the amount of data being transmitted, which can affect audio quality.
MULTICHANNEL USB AUDIO DEVICES
So, what are the options for multichannel USB audio devices that can support surround sound? While they are few and far between, there are some devices that can transmit multiple audio channels over USB.

Some high-end sound cards, such as the Creative Sound Blaster X-Fi or the ASUS Xonar, can support up to 7.1 audio channels over USB. These sound cards often have multiple USB ports, allowing you to connect multiple speakers or a surround sound system.
Audio Interfaces
Audio interfaces, designed for professional audio applications, can also support multiple audio channels over USB. These devices are often used in recording studios and can support up to 16 or more audio channels. Examples include the PreSonus AudioBox or the Focusrite Scarlett series.
USB Speakers
Some USB speakers, such as the Logitech Z906 or the Cyber Acoustics CA-3602A, can support up to 5.1 surround sound over a single USB connection. These speakers often have a built-in amplifier and digital signal processing, making them a convenient option for PC gaming or home entertainment.
SETTING UP A USB SURROUND SOUND SYSTEM
If you’ve decided to use a multichannel USB audio device for surround sound, here are some steps to help you set it up:
Connect the Device
First, connect the USB audio device to your computer using a USB cable. Make sure the device is properly installed and configured according to the manufacturer’s instructions.
