With Lawo’s A__line nodes and their pristine sound, their fully standardized SMTPE 2110 audio streaming capabilities and ST2022-7 class C streaming resilience, you are set for any production, from local to global scale.

OVERVIEW

MANY PORTS. MORE OPTIONS.

Networked, pristine sounding and resilient. A__line nodes are designed to serve as IP audio stageboxes for mc² consoles, audio extensions for the V__matrix ecosystem, or as stand-alone IP audio gateways. A__line features a compelling mix of audio interfacing options.

The discrete, Class-A microphone preamplifier design delivers a superb dynamic range of 119dB(A), ultra low noise at all gain levels and a perfectly flat frequency response. Versatile analog I/O can accommodate levels as high as +24dBu before clipping.

In an IP world, flexible AES3 audio interfacing is paramount. A__line delivers insertable, precise sample rate conversion for each AES3 input—a real life saver when clock domains need to be bridged.

And for multichannel baseband interfacing, A__line features bi- directional MADI access via SFP.

A__line nodes are built for mission-critical IP audio conversion. They use the SMPTE ST2110-30/31 and AES67 standards
to transport uncompressed audio in real-time on Layer-3 IP networks. SMPTE ST2022-7 Seamless Protection Switching guarantees AoIP streaming using dual-redundant network interfaces to provide two discrete paths from device to network core. With ample receive buffer capacity to meet ST2022-7 class C, LAN and WAN network paths can be connected.

A__line provides true flexibility through a non-blocking routing matrix that allows any input to be routed to any output. Furthermore, the nodes simplify level control in a networked infrastructure by offering ppm metering for all Analog and AES3 interfaces.

Additionally, all A__line nodes feature on-board GPI/O (except A__madi 6) as well as PTP/Wordclock sync and conversion. And, of course, they come in a compact and sturdy housing with two redundant power inlets.

FLEXIBLE WITH EASE.

A__line provides audio connectivity in distributed locations. It allows to easily adapt to changing I/O requirements and to scale audio I/O capacity in a networked system — temporarily or permanently.

Based on an SMPTE ST2110-compliant IP audio backbone, A__line offers a granular audio format selection similar to the flexibility found in baseband modular I/O systems. The same backbone technology furthermore eliminates typical system design limitations like maximum channel count per frame, fixed channel capacity per device interconnect, or fixed overall system size.

Audio endpoints connected to A__line nodes can be seamlessly shared on the local or wide-area network. Thanks to the open, fully standardized streaming technology, interconnectivity to a wide variety of IP-enabled broadcast devices is possible. And it is, of course, brand-agnostic.

In combination with Lawo’s VSM broadcast controller, A__line stageboxes provide an advanced set of networking options. VSM indeed manages A__line’s audio-over-IP connections, I/O settings, internal routing matrix and GPIO for smooth integration into an overarching operational workflow.

ACCESS AUDIO ANYWHERE

ON SITE

Rough environmental conditions, frequent setup changes and quick turn-around times are typical for mobile productions. With rock-solid IP networking integration, A__line units are the right choice for outside broadcast, event and remote production scenarios.

AT HOME

Superb sound and flexible stagebox sharing are especially important in broadcast studio deployments. With Lawo’s renowned, pristine sound quality and seamless integration into the mc2 console ecosystem, A__line is a smart choice for any studio environment.

IN THE CORE

24/7/365 operation, direct connectivity to the video infrastructure, and interaction with automation… this is the typical job description for gear that runs the show in a system core. A__line’s resilience and its open, standards-based IP streaming and control interfacing make it a safe fit for the core of any broadcast operation.

SEAMLESS BROADCAST PRODUCTION

Lawo’s A__line has been designed to be installed wherever an audio signal needs to be ingested or output. With a built-in 160ms RX buffer per audio channel and ST2022-7 class C redundancy protection, a WAN gateway is natively built into each A__line unit. This ensures seamless access to the audio streams — whether next door or from another continent.
