Lawo has announced the WAN Edition of the A__line family of networked Audio-to-IP interfaces – compact 1U-high devices capable of streaming uncompressed broadcast-quality audio to Layer 3 networks in real time via both WAN and LAN connections.

Lawo WAN Edition A__line  networked AoIP interfaces

A__line nodes convert mic, line-level, AES3 audio and digitally-encoded baseband Madi to audio-over-IP streaming using open-standard SMPTE 2110-30/31, AES67 and Ravenna protocols. IP-audio streaming is managed using either the open-source Ember+ control API, or standards-based Ravenna advertising and discovery.

New A__line WAN Edition units are optimised for high-traffic, high-demand audio transport. Dual RJ45 ports use SMPTE 2022-7 Seamless Protection Switching (SPS) to provide two discrete, redundant network connection paths, ensuring error-free stream delivery. Dual-redundant power is also available. Ample receive buffer capacities meet ST2022-7 class-C specifications, with redundant path differentials of up to 150ms supported; additionally, up to 160ms of jitter buffer is provided for each received audio channel. A__line units can even synchronize to, and convert between, PTPv2 and word clock reference signals.

The A__line family of audio nodes integrates tightly with Lawo’s VSM IP Broadcast Control System and Lawo mc² audio production consoles. Three models are available: A__mic8 features eight Lawo-grade mic/line inputs and four line-level analog outputs on XLR connectors, eight GPIOs, dual-redundant streaming ports and word clock input and output. The unit is PoE-powered and fanless. A__digital8 has eight AES3 inputs with sample rate conversion, four AES3 outputs on XLR connectors, eight GPIOs, dual-redundant streaming ports and word clock input and output. The unit is PoE-powered and fanless. A__madi4 provides two pairs of redundant Madi interfaces on SFP, two pairs of redundant SFP/RJ45 dual-media streaming ports, and word clock input and output. A__madi4 comes standard with a dual-redundant power supply.

The A__line WAN Edition units are shipping now, and can be ordered from all Lawo dealers.
