Introduction

The AIXpressor is a flexible, software-defined audio processing and interface platform. Unlike traditional stand-alone processors, where functionality is closely tied to fixed hardware and firmware, AIXpressor runs the flexAI software platform. This allows processing functions, codecs, metadata tools, interfaces, and other features to be added or extended through software updates and licensing.

AIXpressor combines real-time audio processing with a wide range of physical and IP-based audio interfaces. Native Audio over IP support includes Livewire+, AES67, and SMPTE ST 2110, while conventional interfaces such as analog audio, AES3, and MADI provide connectivity to existing baseband infrastructure.

This makes AIXpressor suitable both as a stand-alone audio processor and as an interface between traditional audio systems and IP-based environments.

Hardware

AIXpressor is built around a high-performance x86 multi-core processing platform. The main processor handles real-time audio processing, measurement, routing, codecs, Audio over IP, system services, and the web-based user interface.

A high-performance FPGA manages the connection between the processing system and the physical audio interfaces.

The main hardware features include:

On-board Audio Interfaces

AIXpressor includes the following audio interfaces as standard:

MADI and tieLight require different SFP module types. Refer to the corresponding interface section for details.

Expansion Slots

Four expansion slots allow additional physical interfaces to be installed. Each slot provides connectivity for high-channel-count audio applications.

Available interface modules may include:

The exact channel count and capabilities depend on the installed interface module.

Software

AIXpressor runs the flexAI software platform. flexAI separates audio processing functionality from the physical hardware, allowing new applications and features to be added as the software platform evolves.

Processing modules are available in different channel configurations where applicable, ranging from mono and stereo to surround and immersive formats such as 7.1.4.

Available and optional processing functions may include:

The exact set of available functions depends on the installed flexAI software version and licenses.

Audio I/O and Routing

AIXpressor provides analog, AES3, MADI, and Audio over IP connectivity as part of its standard hardware. Additional interfaces can be added using the four expansion slots.

The built-in AES3 and analog interfaces can each be configured as either 8 Inputs / 8 Outputs or 4 Inputs / 12 Outputs. The 4-in / 12-out configuration provides additional output capacity for multichannel and immersive audio formats such as 7.1.4.

The two SFP interfaces can be configured for MADI or the proprietary Jünger Audio tieLight interface. tieLight provides a high-channel-count, low-latency optical connection between compatible systems.

Audio from physical and IP-based interfaces is available to the internal flexAI routing system. Routing operates at channel level, allowing signals from different interface types to be freely combined, rearranged, processed, and routed to available destinations.

Routing configurations can also be stored and recalled as presets.

Control

AIXpressor is primarily operated through its browser-based web interface.

For integration with external control, automation, and monitoring systems, flexAI supports protocols including:

The available control functions may depend on the installed software version and system configuration.

Applications and Use Cases

The flexible combination of processing, routing, conventional audio interfaces, and Audio over IP allows AIXpressor to be used in a wide range of broadcast and professional audio applications.

Typical applications include:

AIXpressor can operate as a dedicated stand-alone processor or as part of a larger flexAI installation with multiple interconnected processing systems.

AIXpressor - Overview

Physical Installation

Physical Installation

AIXpressor is a 1RU, 19-inch rack-mount unit intended for permanent installation in a standard equipment rack. Secure the unit to the rack using four suitable rack screws.

AIXpressor is actively cooled. Viewed from the front, cooling air is drawn in on the left-hand side of the unit and exhausted on the right-hand side. Make sure that the corresponding ventilation openings are not obstructed and that sufficient airflow is available around the unit.

Additional free rack space above or below the AIXpressor is normally not required, provided that adequate ventilation is maintained. In installations with high ambient temperatures or restricted airflow, additional spacing may help improve cooling.

Power

AIXpressor is equipped with two redundant power supplies, each with its own IEC mains inlet and On/Off switch.

For redundant operation, connect both power supplies. If one power supply or its mains feed fails, the second supply can continue to power the unit.

For installations requiring maximum availability, connect the two power supplies to independent mains circuits whenever possible. Ideally, the circuits should also use separate UPS feeds or other suitable backup power arrangements. This helps maintain operation not only in case of a power supply failure, but also if one mains circuit becomes unavailable.

Each power supply can be switched on and off independently.

The power supply modules are located inside the chassis. Replacing a power supply therefore requires opening the unit. Although replacement may technically be possible while the second power supply remains active, this is generally not practical while the unit is installed in a rack.

Important - Please read Safety Informationon proper grounding and electrical safety.

The AIXpressor front panel provides direct access to the following connections and controls:

Rear Panel

AIXpressor Rear

The rear panel provides power, network, synchronization, audio I/O, and expansion connections.

Power

For maximum redundancy, connect the two power supplies to independent mains circuits as described in the Power section.

Network

The assignment of the network ports depends on the system and AoIP configuration.

USB and Service

MADI / tieLight

Two SFP cages provide the built-in MADI / tieLight interfaces.

The operating mode of each interface is selected in the software. MADI and tieLight require different SFP module types.

Depending on the installed module, MADI connections can be provided as optical single-mode, optical multi-mode, or coaxial BNC interfaces.

External Synchronization

A 75 Ω BNC connector provides the external synchronization input.

Supported synchronization formats include:

AES3 I/O

The built-in AES3 interface uses a 25-pin D-Sub female connector.

It can be configured as:

AES3 is also commonly referred to as AES/EBU.

Analog I/O

The built-in analog interfaces use two 25-pin D-Sub female connectors:

This allows the complete analog interface to operate as either:

Expansion Slots

AIXpressor provides four interface expansion slots, IF 1 – IF 4, for optional interface boards.

Each slot supports up to 64 bidirectional audio channels, depending on the installed interface module.

Available expansion modules include interfaces for applications such as SDI, MADI, Dante, AES3, analog audio, and microphone inputs.

AIXpressor - Overview

Network Connections

General Network Considerations

By default, DHCP is enabled on all AIXpressor network interfaces. When connected to a network with an active DHCP server, each interface automatically obtains an IP configuration.

The IP address assigned to LAN 1 CTRL is shown on the front-panel display. If no DHCP server is available, a static IPv4 address can be configured for LAN 1 CTRL from the front panel to establish an initial network connection.

AIXpressor also supports Zero Configuration Networking (mDNS/Bonjour) and can therefore be reached by its .local host name on compatible networks.

Note - The network settings available from the front panel apply to \*\*LAN 1 CTRL\*\* only.

Note - When integrating the AIXpressor into a managed network, coordinate the required IP addressing and network settings with the network administrator.

Accessing the Web Interface

To connect using the IP address shown on the front panel, enter the address in a web browser:

https://<IP-address>

If the AIXpressor is using its factory-installed self-signed certificate, the browser may initially display a certificate warning.

If your computer supports mDNS, the unit can alternatively be reached using its .local host name.

For example:

https://AIXpressor-00080.local

The exact host name is shown on the front-panel display.

The AIXpressor user interface is web-based and can be accessed with a modern desktop or mobile web browser.

Setting a Static IP Address from the Front Panel

A static IP address can be configured from the touch-sensitive front panel. This is useful when no DHCP server is available or when the AIXpressor must first be placed on a specific network before the web interface can be reached.

  1. Open the Menu on the front panel.
