The History of Allen & Heath: From British Mixing Consoles to dLive and Avantis

Few British professional audio manufacturers have a history as extensive as Allen & Heath.

From its beginnings in London during the late 1960s to today's dLive, Avantis and SQ digital mixing systems, Allen & Heath has spent decades developing consoles for live sound, touring, installation, broadcast, studios and DJ applications.

Along the way, its equipment has been used by everyone from emerging bands and local venues to international touring productions and major festivals.

Today, Allen & Heath is one of the most recognisable names in professional mixing – but the company's story began during one of the most exciting periods in British music.

The Beginning of Allen & Heath

Allen & Heath was established in London in 1969.

The late 1960s was a period of enormous change in live music. Concerts were becoming larger, PA systems were becoming more sophisticated and artists increasingly required purpose-built equipment capable of handling more complex productions.

Allen & Heath emerged directly from this environment.

In its early years, the company built custom mixing consoles for some of the leading musicians of the era.

One particularly notable association was with Pink Floyd, who used Allen & Heath equipment as increasingly elaborate sound systems became part of their live performances.

This connection with working musicians helped establish a philosophy that would remain important throughout the company's history: designing consoles around the practical requirements of engineers.

From Custom Consoles to Professional Manufacturing

As professional audio developed through the 1970s and 1980s, mixing consoles became increasingly sophisticated.

Engineers needed:

* More input channels
* Improved equalisation
* Greater routing flexibility
* More auxiliary sends
* Better monitoring
* Increased reliability

Allen & Heath expanded its range accordingly, producing consoles for both live and studio applications.

The company gradually developed a strong international reputation for providing capable mixing systems at competitive price points.

The GL Series

For many live sound engineers, the GL Series became synonymous with Allen & Heath.

Consoles such as the GL2200, GL2400 and GL2800 became extremely common within:

* Rental companies
* Music venues
* Theatres
* Houses of worship
* Schools and universities
* Touring productions

The GL Series offered substantial routing capability without the price or physical size of the largest touring consoles.

Their straightforward analogue workflow also made them popular with engineers who needed to move quickly between different events.

ML Series

At the higher end of the analogue market, Allen & Heath developed consoles including the ML3000, ML4000 and ML5000.

These larger-format desks provided the channel counts and routing capabilities required for more demanding professional applications.

Before digital mixing became dominant, a large analogue console accompanied by racks of external processing represented the standard approach to serious live sound.

Systems could include separate compressors, gates, equalisers, effects processors and crossovers.

Digital consoles would eventually bring much of this functionality inside the desk itself.

The Digital Revolution

The transition from analogue to digital mixing fundamentally changed professional audio.

Instead of transporting a large console and racks of external equipment, engineers could access enormous amounts of processing from a single digital system.

Allen & Heath invested heavily in this transition.

One of the company's most important early digital platforms was iLive.

Allen & Heath iLive

iLive represented a major change in the way Allen & Heath approached professional mixing.

The system separated the control surface from much of the audio processing, allowing engineers to build configurations appropriate to different applications.

This architecture provided significant flexibility.

A touring production might require a substantial control surface, while an installation could use a more compact interface while retaining extensive processing capability.

iLive helped establish Allen & Heath as a serious manufacturer of large-format digital mixing systems.

GLD

Allen & Heath subsequently introduced GLD, bringing many of the advantages of digital mixing to a broader section of the market.

GLD became popular with:

* Regional rental companies
* Theatres
* Houses of worship
* Live music venues
* Corporate production companies

Its combination of touchscreen operation, motorised faders and integrated processing provided a substantial step forward for users moving from analogue consoles.

GLD systems remain active in many installations and rental inventories today.

QU Series

The QU Series extended Allen & Heath's digital technology into a compact and accessible format.

Models including the QU-16, QU-24 and QU-32 became particularly successful.

These consoles offered features that would previously have required significantly larger systems, including:

* Motorised faders
* Digital processing
* Scene recall
* Multitrack recording
* Remote control
* Digital stagebox connectivity

For smaller venues and production companies, QU provided a practical route into professional digital mixing.

The Arrival of dLive

The introduction of dLive marked one of the most important developments in Allen & Heath's history.

Designed for demanding professional applications, dLive was built around the company's XCVI FPGA processing architecture.

Rather than simply creating another digital console, Allen & Heath developed a scalable mixing ecosystem.

A dLive system typically consists of a MixRack containing the processing and audio connections combined with a control surface.

This architecture allows different components to be selected depending on the production.

dLive S Class and C Class

The dLive range includes different surface and MixRack options, enabling systems to be configured for a wide variety of applications.

S Class surfaces are designed for demanding touring and professional productions, while the more compact C Class provides access to the same broader dLive ecosystem in a smaller format.

This flexibility has been particularly attractive to rental companies.

Inventory can potentially be configured differently depending on the requirements of each production.

Why dLive Became So Popular

Several factors have contributed to the success of dLive.

Processing Power

Modern productions require enormous amounts of channel processing, routing and effects.

dLive provides substantial processing capability within an integrated system.

Flexible Workflow

Engineers can configure surfaces and controls around their preferred method of working.

Scalability

Different surfaces, MixRacks and expansion options allow systems to be adapted for different applications.

Sound Quality

The platform has developed a strong reputation among professional live sound engineers.

Compact Touring Systems

Powerful processing no longer necessarily requires an enormous control surface.

This can reduce transport space and simplify deployment.

Allen & Heath SQ Series

While dLive addressed high-end professional applications, the SQ Series brought Allen & Heath's newer generation of digital processing into a smaller format.

The range includes:

* SQ-5
* SQ-6
* SQ-7

SQ consoles have become extremely popular with rental companies, venues, theatres, houses of worship and touring musicians.

Their compact dimensions make them easy to transport while still providing substantial mixing capability.

For smaller productions, an SQ system can replace a considerable amount of equipment that would once have required a large analogue console and external processing racks.

Avantis

Allen & Heath later introduced Avantis, positioned between SQ and dLive.

Avantis combines a dual-screen control surface with substantial processing capability and a workflow influenced by dLive.

This positioning makes it particularly interesting for production companies.

Some applications require more capability and physical control than an SQ system provides but do not necessarily justify a larger dLive configuration.

Avantis fills that space.

Avantis Solo

The Avantis platform was subsequently expanded with Avantis Solo.

By reducing the physical size of the control surface while retaining the wider Avantis ecosystem, Allen & Heath created another option for touring and space-conscious applications.

The trend towards smaller but increasingly powerful consoles reflects a major change across the professional audio industry.

Transport costs, control-position space and setup time are increasingly important considerations for rental companies and touring productions.

Everything I/O

Another strength of the modern Allen & Heath ecosystem is the wide range of remote audio and expansion options.

Digital stageboxes allow microphone inputs and outputs to be positioned close to the stage while the mixing console communicates with them digitally.

This significantly reduces the amount of analogue multicore cabling required.

For touring productions, this can mean:

* Faster setup
* Less cabling
* Reduced transport weight
* Greater flexibility
* Easier system expansion

Allen & Heath and Audio Networking

Professional audio systems increasingly depend on networked infrastructure.

Modern Allen & Heath systems can be integrated with technologies used for distributing audio between consoles, stageboxes, computers and other equipment.

This is particularly important for larger productions where front of house, monitors, recording and broadcast systems may all need access to the same audio sources.

Don't Forget Xone

Allen & Heath's influence extends beyond conventional live sound.

The company's Xone range has developed a formidable reputation within professional DJ equipment.

Products such as the Xone:92 and Xone:96 have become favourites among DJs who prefer a traditional mixer-focused workflow and high-quality analogue sound.

This has given Allen & Heath an unusually broad presence across professional audio, spanning concert mixing, installations and club culture.

Why Rental Companies Choose Allen & Heath

Allen & Heath equipment is attractive to rental businesses for several reasons.

Wide Product Range

A rental company can operate SQ systems for smaller events, Avantis for medium-sized productions and dLive for larger shows.

Familiarity

A substantial number of engineers are comfortable operating Allen & Heath consoles.

Scalability

Digital stageboxes and modular system components allow inventory to be deployed in different configurations.

Compact Size

Modern Allen & Heath systems provide considerable processing capability without requiring excessively large control surfaces.

Demand

dLive, Avantis and SQ are widely used across touring, theatre, corporate and installation markets.

Buying Used Allen & Heath Consoles

The popularity of the brand has created a healthy international market for used Allen & Heath equipment.

Frequently sought-after products include:

* dLive S5000
* dLive S7000
* dLive C1500
* dLive C2500
* dLive C3500
* CDM and DM MixRacks
* Avantis
* SQ-5
* SQ-6
* SQ-7
* QU Series
* Xone mixers

Older GLD, iLive and analogue GL Series consoles can also remain useful depending on the application and price.

What to Check When Buying a Used Digital Console

Professional mixing consoles can spend years on the road, so condition should be assessed carefully.

Important areas include:

* Touchscreen condition
* Fader operation
* Rotary encoders
* Buttons and switches
* Network ports
* Audio connections
* Power supplies
* Software and firmware
* Flightcase condition

For modular systems such as dLive, buyers should also establish exactly which MixRack, surface, expansion cards and accessories are included.

Two listings described simply as a "dLive system" can represent very different packages.

Used dLive Systems

dLive is particularly interesting within the used professional audio market because of its modular architecture.

A buyer may be looking for a complete touring package or simply an individual surface, MixRack or expansion component.

Understanding compatibility is therefore important.

A well-specified used package can provide a production company with access to a high-end professional mixing platform at a substantial saving compared with purchasing an equivalent system new.

Allen & Heath vs DiGiCo and Yamaha

At the professional touring level, Allen & Heath frequently sits alongside manufacturers such as DiGiCo and Yamaha on equipment lists.

Each platform has its own workflow, architecture and loyal user base.

Rather than there being one console suitable for every engineer, the choice often depends on:

* Required channel count
* Processing requirements
* Engineer preference
* Existing inventory
* Networking requirements
* Touring footprint
* Budget

The growth of dLive demonstrates that Allen & Heath has successfully established itself within this highly competitive part of the market.

The Future of Allen & Heath

The direction of professional mixing is clear: more processing, greater networking capability and increasingly powerful systems housed within smaller physical footprints.

Software integration and remote control are also becoming more important.

Allen & Heath's current product ecosystem places the company in a strong position across multiple levels of the professional market.

From an SQ-5 used for a small event to a substantial dLive system running a major touring production, the same manufacturer can now serve an enormous range of applications.

Conclusion

Allen & Heath's journey from building mixing consoles in London in 1969 to developing today's dLive, Avantis and SQ platforms spans more than five decades of professional audio innovation.

The company successfully navigated the transition from analogue to digital mixing while retaining a strong focus on practical tools for working engineers.

Products such as the GL Series, iLive and GLD established important chapters in its history, while dLive, Avantis and SQ have introduced the brand to a new generation of audio professionals.

For venues, touring engineers and rental companies, Allen & Heath now offers one of the most comprehensive mixing ecosystems in professional audio.

And with strong demand for dLive, Avantis and SQ equipment, it has also become an increasingly important manufacturer within the global used professional audio market.
