Three L-Acoustics LA12X Amplified Controllers

At the heart of the LA-RAK II AVB are three LA12X amplified controllers.

The LA12X is a 4 x 4 amplified controller with integrated DSP, networking and loudspeaker management capabilities. Each controller provides four amplifier channels, giving a complete LA-RAK II AVB a total of 12 amplification channels.

L-Acoustics specifies the LA12X at:

* 4 × 3,300 W at 2.7 ohms
* 4 × 2,600 W at 4 ohms
* 4 × 1,400 W at 8 ohms

The LA12X uses a universal switched-mode power supply with power factor correction and supports 100 V to 240 V ±10%, 50–60 Hz. It also provides Milan-AVB, AES/EBU and analog audio connectivity. (L-Acoustics)

The integrated DSP provides flexible 4 × 4 routing, built-in equalization and L-Acoustics loudspeaker processing functions. This allows the amplifier controllers to operate as part of a complete L-Acoustics loudspeaker system rather than functioning as conventional standalone power amplifiers.

Two LS10 AVB Network Switches

The LA-RAK II AVB includes two L-Acoustics LS10 AVB switches.

The LS10 is an Avnu-certified AVB switch designed for audio and control distribution. Within the LA-RAK II AVB architecture, the two LS10 units provide the network infrastructure for Milan-AVB audio and control.

The redundant architecture is particularly important in professional touring applications. The two LS10 switches are integrated with the LA12X controllers to provide seamless network redundancy following the Milan protocol.

The LS10 provides eight EtherCON connections as well as SFP cages that can be used for additional copper or optical connectivity. This makes the network architecture suitable for larger professional production environments where reliable signal distribution is essential. (Prdstglaxxwe001)

Milan-AVB Network Redundancy

One of the defining characteristics of the L-Acoustics LA-RAK II AVB is its Milan-certified network architecture.

The rack supports Milan-AVB audio and control distribution with seamless network redundancy. This allows professional sound engineers and system technicians to build robust networked audio systems while maintaining the dedicated L-Acoustics signal and control architecture.

For touring productions, network redundancy can be particularly valuable because audio distribution and system control are fundamental to the operation of the sound system.

The LA-RAK II AVB is therefore more than an amplifier rack. It is an integrated amplification and network distribution platform designed around the L-Acoustics ecosystem.

LA-PANEL II Audio Distribution

The LA-RAK II AVB incorporates an LA-PANEL II audio distribution panel.

The LA-PANEL II provides the physical interface for distributing analog and digital audio signals to the three LA12X amplified controllers.

The rack provides two 19-point CA-COM analog input connectors and rear analog XLR inputs. It also provides AES/EBU connectivity using Neutrik XLR connectors.

The integrated distribution architecture helps keep connections organized and reduces the amount of loose cabling required during touring deployment.

According to the L-Acoustics system documentation, the LA-PANEL II distributes six discrete analog signals and three stereo AES/EBU signals to the three LA12X controllers, with link-out capability to other racks. (Prdstglaxxwe001)

LA-POWER II Power Distribution

The LA-RAK II AVB also includes LA-POWER II for integrated power distribution.

LA-POWER II is designed to distribute mains power to the three LA12X controllers while balancing the amplifiers across the available phases.

For European operation, the rack provides three-phase 32 A IEC 60309 input and link connections. For US operation, it provides a 30 A NEMA L21-30P connection.

The rack also includes auxiliary power outlets. The US configuration provides a NEMA 5-15 outlet, while the EU configuration provides a Type F Schuko outlet.

This makes the LA-RAK II AVB suitable for international touring applications where the rack may need to operate across different power environments. (L-Acoustics)

Worldwide 100–240 V Compatibility

The LA-RAK II AVB is designed for international touring environments.

Its LA12X amplified controllers use universal power supplies supporting 100–240 V ±10%, 50–60 Hz. The rack itself provides different power input arrangements for European and US operating modes.

This international compatibility can simplify equipment deployment for rental companies, touring productions and professional sound providers operating across different regions.

However, the appropriate power input configuration, electrical protection and local regulations must always be verified before operation.

Flyable Touring Rack Design

The LA-RAK II AVB is specifically designed as a flyable touring rack.

The rack structure includes coupling bars and coupling rails that allow compatible racks to be mechanically connected for stacking or flying applications.

L-Acoustics documentation states that the RK 9U rack can be stacked up to three LA-RAK II AVB racks and can be flown up to four LA-RAK II AVB racks when using the appropriate flying hardware. (Prdstglaxxwe001)

The dedicated LA-RAK BUMP is engineered for flying up to four LA-RAK II racks and provides the appropriate mechanical interface for supported flown configurations. (Prdstglaxxwe001)

This makes the LA-RAK II AVB particularly useful for touring productions where amplification racks may need to be flown close to the loudspeaker system or positioned in dedicated production areas.

Rugged Touring Construction

Touring equipment must withstand repeated transportation, loading, unloading and deployment.

The LA-RAK II AVB uses a rugged rack construction designed specifically for professional touring.

The 9U rack incorporates a shock-absorbing inner steel frame, an external aluminium structure and highly resistant polyethylene panels. Retractable LEXAN® doors protect the electronics during transportation.

This construction helps protect the integrated LA12X controllers, LS10 switches and distribution components while allowing the rack to remain practical for professional handling. (Prdstglaxxwe001)

Protective Front and Rear Doors

The LA-RAK II AVB features retractable protective doors at the front and rear.

The doors provide protection for the electronics and connectors during transport while allowing technicians to access the equipment during setup.

At the rear, hinge-mounted panels protect the analog, digital and network connections and help maintain an organized cable environment.

For touring companies, this integrated protection can reduce the amount of additional packaging required when transporting the rack between venues.

Detachable Dolly Board

The LA-RAK II AVB is supplied with a detachable dolly board.

The dolly board allows the rack to be moved around production areas, warehouses and venues more easily.

The rack also includes four handles for handling and positioning.

Together, the dolly board, handles and rugged rack structure make the LA-RAK II AVB practical for touring crews and professional rental operations.

LA-RAK II AVB for Touring Companies

The L-Acoustics LA-RAK II AVB is designed around the needs of touring productions.

A touring system needs to be efficient to transport, fast to deploy and reliable during operation. Integrating three LA12X controllers, two LS10 switches and the required power and signal distribution into one rack simplifies the equipment package.

Instead of assembling multiple separate rack components at every venue, technicians can deploy a preconfigured amplification and networking platform.

This can help standardize system deployment between venues and reduce setup complexity.

LA-RAK II AVB for Rental Companies
