The audio processing is handled by the external, ARM-based NEX:T core in a 1 RU chassis. In its initial configuration, the system provides 64 × 64 audio channels and up to 64 buses, with a future expansion to up to 256 channels planned. Physical audio I/O can be connected flexibly via NEXUS compact or AXIO. The control surface itself requires no local audio processing and is powered via PoE.

Essential functions such as routing, monitoring, and DSP processing can be controlled locally or remotely via the central web interface and virtual panel. This allows ON AIR to be used both as a conventional radio console and as a networked control position.

Fits your radio workflow

Whether for self-op, live assist, automated broadcasting, or centralcasting: ON AIR combines hands-on console operation with centralized control over the network. Standardized on-air logic, N-1 mix-minus, talkback, and monitoring support typical radio workflows. Interfaces enable integration with radio automation and centralized control systems.

DESIGNED FOR RADIO. MODULAR. IP-BASED. 

Concept

ON AIR is a modular, scalable radio console system designed for self-op studios, regional broadcasters, and networked radio infrastructures. The control surface can be configured with six to 24 motorized faders to suit different studio and workstation sizes.

The control surface and audio processing are completely separate. The external, ARM-based NEX:T core handles mixing, signal processing, and routing, while the ON AIR control surface is powered via PoE. This keeps the workstation compact and allows it to be positioned independently of the processing and audio I/O.

With IP integration and a centralized web interface, ON AIR can be operated locally or remotely and integrated into networked radio workflows. Whether in a self-op studio, an auxiliary studio, a decentralized editorial workstation, or for centralcasting: the system combines hands-on operation with centralized configuration and control.

Application Areas

Self-Op Radio: Designed for live presentation and automated broadcast workflows.

Direct, clear, and intuitive.
The ON AIR console is designed for intuitive self-op operation. Presenters can control the essential functions of their broadcast directly from the console or via the central web interface and virtual panel.

Automated – and Always under control.
Configurable logic and supported interfaces allow ON AIR to be integrated into automated radio workflows. Live assist, automated broadcasts, and manual interventions by presenters can be seamlessly combined within a single workflow.

Connected for auxiliary studios and centralcasting.
The compact, PoE-powered control surface and network connectivity via AES67 and SMPTE ST 2110-30 enable deployment in auxiliary studios, at decentralized editorial workstations, and in centrally managed radio studios. Configuration and operation can be performed independently of location via the network.

Features

NEX:T core – the scalable audio engine for ON AIR 

The external, ARM-based NEX:T core in a 1 RU chassis handles mixing, signal processing, and routing. In its initial configuration, ON AIR processes 64 × 64 audio channels and provides up to 64 buses. The architecture is designed to support future expansion to up to 256 channels. Processing, control, and audio I/O can be positioned independently of one another. NEXUS compact or AXIO provide the physical audio connectivity. Operation is available either directly from the modular ON AIR control surface or, depending on the workflow, via the browser-based virtual panel.
