Lawo is pleased to unveil of a new series of AoIP stageboxes at BVE 2019 as part of the well-established A__line family of AoIP devices: the WAN-capable, A__stage series of live-performance interfaces, with premium features such as discrete Class A Mic preamps, advanced digital A/D FIR filtering, and SMPTE 2022-7 Seamless Protection Switching (SPS), providing two discrete, redundant network links to ensure network connection stability.
Three new A__stage devices will premiere at BVE. All feature switchable Mic/Line inputs capable of handling balanced or unbalanced sources, AES3 I/O with broadcast-grade sample-rate conversion, PTP/Word clock sync and conversion capability, and dual-redundant power inlets. The A__stage family includes:
A__stage 80, a maximum-capacity 3RU multi-input AoIP stagebox with Mic, Analog line, and AES3 I/O presented on standard, high-density D-SUB connections. It features 32 switchable Mic / Line inputs, 32 Analog line outputs, 8 stereo AES3 inputs and 8 stereo AES3 outputs. A__stage 80 also includes dual-redundant MADI ports on SFP, 8 opto-isolated GPIO ports, and dual 1000BT streaming and control ports on SFP/RJ45. A separate management port is supplied on RJ45.
A__stage 48 supplies 16 switchable Mic / Line inputs, 16 Analog line outputs, 8 stereo AES3 inputs and 8 stereo AES3 outputs on standard D-SUB connectors, with dual-redundant MADI ports on SFP, 8 opto-isolated GPIO ports, dual 1000BT streaming and control ports on SFP/RJ45, and 1000BT management port on RJ45, in a 3RU form.
A__stage 64, for applications where discrete I/O is preferred, has a capacity of 32 switchable Mic / Line inputs, 16 Analog line outputs, 8 stereo AES3 inputs and 8 stereo AES3 outputs, presented on XLR connections. Like the other A__stage products, dual-redundant MADI ports on SFP, 8 opto-isolated GPIO ports, dual 1000BT streaming and control ports and 1000BT management port, in a 4RU package.
Lawo A__line AoIP nodes are compact devices capable of streaming uncompressed broadcast-quality audio to Layer 3 networks in real time via both WAN and LAN connections. A__line nodes effortlessly convert audio – mic, line-level, AES3 and even digitally-encoded baseband MADI – to audio-over-IP streaming traffic 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.
Additionally, A__line provides true flexibility through a non-blocking routing matrix that allows any input to be routed to any output, and simplify level control in networked infrastructures by supplying ppm metering for all Analog and AES3 interfaces. They integrate tightly with Lawo’s VSM IP Broadcast Control System and mc² audio production consoles, and serve as IP audio stageboxes for mc² consoles, audio extensions for the V__matrix ecosystem, or as stand-alone IP audio gateways.
