In the world of audio technology, the terms ‘analog snake’ and ‘digital snake’ are frequently mentioned. These pieces of equipment are used to transmit audio signals over distances, often between the stage and the sound booth in live sound setups.
But what exactly are they, and how do they differ from each other? More importantly, how do you determine which one is the right choice for your audio setup? Let’s start by looking at digital snakes.
What is the purpose of a digital snake?
A digital snake is used to transmit multiple channels of digital audio signals from one location to another, typically between a stage and a mixing console, thereby reducing the complexity and size of cable bundles required in audio setups. It also improves audio quality over long distances by minimizing noise and signal degradation.
The remainder of this article provides an in-depth comparison between analog and digital snakes. We’ll explore their purposes, advantages, and disadvantages, and delve into related topics such as the use of stage boxes and the concept of ‘returns’ in a stage snake.
What Is The Purpose Of A Digital Snake?
A “digital snake” in the context of audio technology refers to a device that transmits audio signals in a digital format from one location to another. They are often used in live sound situations, recording studios, and broadcasting environments.
In traditional analog setups, individual cables are required for each audio channel that needs to be transmitted. This can lead to a large, unwieldy bundle of cables, commonly referred to as a “snake.” The more channels you need, the larger the snake becomes, increasing the complexity of the setup and the potential for signal degradation or interference.
A digital snake, on the other hand, can transmit multiple channels of audio over a single cable, such as an Ethernet cable in the case of an audio-over-IP system. This simplifies the setup, reduces the potential for signal degradation or interference, and makes the system more portable and easier to manage.
Digital snakes can also allow for remote control of microphone preamplifiers and other devices, and support for digital audio formats with higher quality than traditional analog signals.
In most situations “digital snake” refers to both the physical cable and the digital system that includes both the cable and the devices at either end that convert between analog and digital signals.
In summary, the purpose of a digital snake is to transmit multiple channels of audio signals in a digital format over a single cable, simplifying setup and potentially improving audio quality.
Advantages Of Digital Snake
Digital snakes offer several advantages over traditional analog snakes:
- Simplicity and Portability: Digital snakes use a single cable to transmit multiple channels of audio, reducing the complexity and size of the cable bundle. This makes the setup more portable and easier to manage.
- Improved Audio Quality: Digital audio is less susceptible to noise and signal degradation over long distances than analog audio. This can result in improved audio quality, particularly in environments with a lot of electrical noise or where long cable runs are required.
- Scalability: Digital snakes can easily support a large number of audio channels, making them scalable for different sizes of events or installations. Adding more channels typically just requires additional hardware at either end of the snake rather than more cables.
- Remote Control: Some digital snakes support remote control of devices like microphone preamps, allowing for adjustments to be made from the mixing console rather than at the stage.
- Flexibility: Digital snakes can often be integrated with existing networking infrastructure, providing flexibility in how they’re set up and used. They can also support a variety of digital audio formats and transmission protocols, providing more options for system design.
- Cost-effectiveness: Although the initial investment for digital snake systems may be higher, the long-term benefits like reduced cable costs, less physical infrastructure, enhanced control, and superior audio quality often make them a more cost-effective solution in the long run.
- Integration with Digital Systems: Digital snakes can seamlessly integrate with digital mixing consoles and recording systems, allowing for a fully digital signal path from the microphones to the speakers or recording device. This can further improve audio quality and provide additional options for signal processing and routing.
These advantages make digital snakes a popular choice for many live sound, recording, and broadcasting applications.
Disadvantages Of Digital Snake
Despite the many advantages of digital snakes, there are also some potential disadvantages to consider:
- Initial Cost: The initial investment for a digital snake system can be higher than for an analog system. This includes the cost of the digital snake itself, as well as any necessary converters, interfaces, or other equipment.
- Complexity: While digital snakes can simplify the physical setup, they can also add complexity in other areas. For example, setting up and configuring a digital snake system can require a good understanding of digital audio, networking, and the specific protocols used by the system.
- Dependence on Power: Digital snakes require power for the converters and other devices at either end of the snake. This can add another potential point of failure, particularly in live sound situations where power availability can be unpredictable.
- Latency: Digital systems can introduce latency, which is the delay between when an audio signal is input into the system and when it is output. While this latency is typically small, it can become a problem in certain situations, particularly for musicians who are sensitive to timing.
- Compatibility: Not all digital snakes are compatible with all equipment. For instance, some digital snakes use specific protocols that may not be supported by all mixing consoles or other devices. This requires careful planning and consideration when designing a system.
- Potential for Data Loss: Although digital audio is less susceptible to noise and signal degradation, it can be more susceptible to data loss. If a digital signal is lost or corrupted, it can result in a complete loss of audio, whereas an analog signal might just be degraded but still usable.
- Learning Curve: Because digital snakes involve a different way of handling audio compared to analog snakes, there can be a learning curve for sound engineers and other users who are used to analog systems.
Despite these potential disadvantages, many people find that the benefits of digital snakes outweigh the drawbacks, particularly for larger or more complex audio setups. However, it’s important to carefully consider these factors when deciding whether a digital snake is the right choice for a particular situation.

Digital Snake Vs Analog Snake
Both digital and analog snakes serve the same basic function: they transmit multiple audio signals from one location to another. However, the methods they use to do so, and the implications of those methods, differ significantly. Here’s a comparison of digital snakes and analog snakes:
Analog Snake
Analog snakes are bundles of individual cables, each carrying one channel of analog audio. The signals are sent directly from the source to the destination without any conversion or processing.
Advantages:
- Simplicity: Analog snakes are relatively simple to set up and use. If a cable within the snake fails, it can usually be replaced individually.
- Direct Connection: Each channel is connected directly from source to destination without any conversion or processing. This can sometimes be preferred in situations where the lowest possible latency is important.
- Compatibility: Analog snakes use standard audio connectors and signals that are compatible with nearly all audio equipment.
Disadvantages:
- Bulk and Weight: Analog snakes can become quite large and heavy when many channels are required, making them difficult to handle and install.
- Susceptibility to Interference: Analog signals can be susceptible to interference and degradation, particularly over longer distances or in environments with a lot of electrical noise.
- Limited Remote Control: Analog snakes don’t typically support remote control of devices like microphone preamps.
Digital Snake
Digital snakes convert the audio signals to digital format at the source, transmit the digital signals over a single cable or network connection, and then convert them back to analog at the destination.
Advantages:
- Reduced Bulk and Weight: Digital snakes can transmit multiple channels of audio over a single cable, reducing the size and weight of the snake.
- Improved Audio Quality: Digital signals are less susceptible to noise and degradation over long distances.
- Remote Control: Some digital snakes support remote control of devices like microphone preamps.
- Scalability: Digital snakes can easily support a large number of channels.
- Flexibility: Digital snakes can support a variety of digital audio formats and transmission protocols, and can often be integrated with existing networking infrastructure.
Disadvantages:
- Cost: The initial cost of a digital snake system can be higher than an analog system.
- Complexity: Setting up and configuring a digital snake system can be more complex than an analog system.
- Power Requirements: Digital snakes require power for the converters and other devices at either end of the snake.
- Compatibility: Not all digital snakes are compatible with all equipment.
- Potential for Data Loss: If a digital signal is lost or corrupted, it can result in a complete loss of audio.
Both types of snakes have their uses, and the best choice depends on the specific requirements of the situation. Digital snakes are often preferred for larger or more complex setups, while analog snakes may still be used in simpler or smaller-scale situations or where their specific advantages are needed.
Can I Use an Analog Snake With a Digital Mixer?
An analog snake can be used with a digital mixer. The key point to understand is that the snake, whether analog or digital, is merely a method for transmitting audio signals over a distance. It does not determine the nature of the signals themselves.
In a typical setup with an analog snake and a digital mixer:
- Microphones or other audio sources generate analog audio signals.
- These analog signals are sent over the analog snake to the mixer.
- At the mixer, these analog signals are converted into digital signals by the mixer’s analog-to-digital converters (ADCs). The mixer then processes these digital signals as needed.
- The processed digital signals are then converted back into analog signals by the mixer’s digital-to-analog converters (DACs) to be sent to the speakers or other output devices.
So even though the mixer is digital, it can still work with analog signals coming from an analog snake. The important thing is that the mixer has the necessary ADCs to convert the incoming analog signals into digital form. This is standard on all digital mixers.
If you are using a digital snake, you’ll need to ensure the digital signals it sends are compatible with your digital mixer. Some digital snakes send digital signals using specific formats or protocols that may not be supported by all mixers.
What Is A Digital Stage Box?
A digital stage box, also sometimes referred to as a stage box, digital snakehead, or remote I/O (input/output) unit, is a device that is used in conjunction with a digital audio mixing console in live sound or recording environments.
The stage box is typically placed on or near the stage and serves as the primary interface between the microphones, instruments, and other audio sources on the stage and the digital mixing console.
A digital stage box contains a number of input and output connections, typically XLR or 1/4″ jacks, to connect the microphones and instruments. Inside the stage box, these analog audio signals are converted into a digital format by analog-to-digital converters (ADCs).
The digital signals are then sent over a single cable or network connection to the mixing console, often using a digital snake. This significantly reduces the amount of cabling required compared to traditional analog systems.
At the mixing console, the digital signals are processed as needed and can then be sent back to the stage box over the same connection. The stage box converts the digital signals back into analog form with digital-to-analog converters (DACs) and sends them out to the speakers or other output devices.
Many digital stage boxes also support remote control from the mixing console, allowing for adjustments to preamp levels and other parameters without having to physically access the stage box.
A digital stagebox is a key component of a digital audio system, serving as the interface between the analog audio sources and the digital mixing console, and significantly simplifying the cabling and setup process.
What Is A Return On A Stage Snake?
In the context of a stage snake, a “return” refers to a channel that is used to send audio signals from the mixing console back to the stage.
In a typical live sound setup, most of the channels on a snake are used to send audio signals from the microphones and instruments on the stage to the mixing console. These are often referred to as “sends” or “inputs.”
However, there are usually a few channels that are used to send audio signals in the opposite direction, from the mixing console back to the stage. These are the “returns” or “outputs.” They are typically used for things like stage monitors or in-ear monitors, which allow the performers to hear themselves and each other, or for sending signals to amplifiers on the stage.
The returns on a snake are often distinguished from the sends by using different connectors (for example, XLR female connectors for the sends and XLR male connectors for the returns), or by labeling or color-coding.
In a digital snake or stage box system, the sends and returns are typically handled by the same network connection, with the stage box handling the necessary conversions between analog and digital signals.
The number of sends and returns available will depend on the specific capabilities of the stage box and the digital audio system.
