Mixing Consoles: Analog, Digital, then Dematerialized

Having started my career in sound with analog consoles, I have personally witnessed the fascinating evolution of these devices over the years. The world of mixing consoles has undergone a significant technological transformation over the decades. What were once imposing analog giants have gradually become more compact with the advent of digital technology, before taking an even more radical turn: dematerialization. Today, it is possible to mix an entire concert or album without ever touching a physical fader, using only a tablet or computer. This article explores the fascinating evolution of mixing consoles, from the analog era to the current dematerialized era.

The Analog Era: The Reign of Massive Physical Consoles

For decades, analog mixing consoles reigned supreme in recording studios and live sound. These consoles were true engineering marvels, with endless rows of faders, potentiometers, VU meters, and switches. Each channel had its own signal path, and technicians had to physically interact with each element to adjust levels and apply effects.

Advantages of Analog Consoles

• Warmth of Sound: Many sound engineers preferred (and some still prefer) the natural and "warm" sound of analog consoles. The electrical circuits and transformers added a slight coloration to the sound, which some found more pleasant to the ear.
• Immediate Physical Interface: The ability to instantly adjust parameters with physical buttons provided intuitive control. There was no latency between action and effect.

Disadvantages of Analog Consoles

• Size and Weight: Analog consoles were often massive, sometimes weighing several hundred kilos, and took up considerable space in studios or concert halls.
• Lack of Flexibility: Each adjustment had to be made manually, making it difficult to memorize or recall previously used settings. Adjustments had to be made in real-time, with no possibility of saving configurations.

The Digital Revolution: More Compact and Smarter Consoles

With the introduction of digital mixing consoles, the audio industry took a major step forward in the 1990s and 2000s. These digital consoles combined powerful signal processing with a physical interface that was increasingly compact. The digital revolution not only improved the portability and flexibility of consoles but also introduced functionalities that were previously unimaginable with analog systems.

Advantages of Digital Consoles

• Presets and Memories: Digital consoles allowed engineers to save entire configurations for later use, which was impossible in the analog world. This feature was especially useful for tours, recurring shows, or studio sessions.
• Built-in Effects: Digital consoles often integrated effects processors (EQ, compression, reverb, etc.) without the need for external hardware. This simplified the workflow and reduced costs.
• More Compact and Lightweight: By removing bulky analog circuits, digital consoles were much more portable. Some consoles could handle hundreds of channels while fitting into a much smaller form factor.
• Automation: The automation of parameters and snapshot management allowed for incredible precision, especially for large live productions.

Disadvantages of Digital Consoles

• Sometimes Less Intuitive Interface: Although digital consoles offered many new features, they could sometimes be more complex to master, with menus and submenus that were not easily accessible during mixing.
• Risk of Failure: Like any electronic device, a digital console could suffer from software or hardware issues, whereas analog consoles were generally more robust and reliable.

The Dematerialization Era: Mixing Without a Physical Console

Today, we are witnessing a new revolution in mixing with the advent of dematerialized consoles. These systems manage sound entirely through a rack or a box containing preamps and connection interfaces, but all controls are done remotely via a tablet, smartphone, or computer.

Among the standout products in this category are models like the Behringer X Air XR18 or the Midas MR18, which allow users to control up to 18 channels through an intuitive software interface, without any physical console.

Advantages of Dematerialized Consoles

• Ultra Portability: These systems take up very little space and are very lightweight. A simple rack or box and a tablet are enough to control a complex mix.
• Remote Control: You no longer need to be physically at the console. In live settings, this allows the sound engineer to move freely around the venue to adjust the sound based on actual acoustic perception.
• Reduced Cost: By eliminating the physical console, manufacturing costs — and therefore the price for the consumer — are significantly reduced. This makes advanced technologies accessible to smaller setups.
• Intuitive Interface: Touchscreen interfaces allow users to quickly visualize levels, access effects, and adjust parameters with a simple gesture, offering flexibility that rivals traditional digital consoles.

Disadvantages of Dematerialized Consoles

• Dependency on Technology: If your tablet or computer encounters an issue, it could compromise your entire mixing system. Additionally, a network failure or Wi-Fi issue could cause problems during a live event.
• Lack of Physical Feedback: Some sound engineers still prefer the feel of controlling a physical fader or button, which is not possible with an entirely touchscreen interface.

Impact on the Music and Audiovisual Industry

The arrival of dematerialized consoles has profoundly changed the landscape of sound engineering, especially in live events, music tours, and even mobile studio recordings. Artists and bands who would not have had access to professional mixing equipment can now achieve sophisticated mixes with just an iPad or Android tablet.

Additionally, this flexibility allows a single technician to manage a concert or mixing session from almost anywhere in the venue, or even remotely via a local network. This dematerialization has made advanced features more accessible and democratized high-quality mixing.

The Future of Mixing: Toward Complete Dematerialization?

With continuous advancements in information and communication technologies, it is likely that the dematerialization of mixing consoles will continue to evolve. Cloud-based systems could allow sound engineers to control and collaborate on mixes from different locations worldwide, opening up new creative possibilities.

Furthermore, artificial intelligence algorithms could enable autonomous mixing systems that adjust parameters in real-time based on the acoustic characteristics of the venue, the musical style, or the preferences of the artists.

Conclusion: A Journey from Physical to Invisible

The evolution of mixing consoles, from analog to digital and then to dematerialization, represents far more than just a technological change. It is a true paradigm shift in how sound is managed, controlled, and produced. While analog consoles embodied a purely physical and material approach to sound, digital consoles combined power and flexibility, while the current era of dematerialized consoles offers an approach that blends efficiency, compactness, and total freedom.

The future of mixing is both promising and fascinating, with unexplored possibilities in remote control, automation, and artificial intelligence. One thing is certain: the art of mixing will continue to evolve, but the solid foundations laid by analog consoles will always remain a reference for sound engineers.
