Linear Acoustic has introduced AERO.x, a light-weight, half-rack IP-audio interface that combines dual independent HD-SDI paths and processes up to 16 channels of audio.
The unit has built-in AEROMAX loudness processing and dual compensating video delay to maintain audio/video synchronization.
Dual, independent HD/SD-SDI I/O plus Livewire/AES67 audio over IP provides flexible local and networked audio connectivity. Compensating video delay for each SDI input ensures that audio/video synchronization is maintained.
AERO.x is designed for high-density installations and can also be used where only a few processors are required or even as a stand-alone desktop unit. High quality audio is provided in a compact, feature rich, cost effective and expandable manner.
The device contains up to two processing engines, each of which can be either 2+2+Dual ITU Meters or 5.1+Upmix+Downmix+Dual ITU Meters. Audio sources can be applied to either or both engines from any channels present on the SDI inputs or via Livewire/AES-67 audio over IP.
AERO.x includes the AEROMAX adaptive wideband and multiband, multistage ITU compliant loudness control algorithm. Upmixing is provided by the Hollywood-approved UPMAX algorithm which provides a 5.1-channel audio experience while AutoMAX-II automatically bypasses upmixing for 5.1 channel content.
Broadcast facilities have been using Axia Livewire AoIP (audio over IP) technology to route hundreds of audio channels using standard Ethernet switches, cables and other components.
Livewire conforms to the AES- 67 standard. It is the technology upon which Ravenna is built. It also significantly reduces the number of cables and wires needed to transport and share audio throughout the broadcast plant.
Nearly any audio source — analog, AES and SDI — and myriad equipment from phone systems to codecs to satellite receivers — can be made a part of a Livewire network.
The AERO.x is a 1RU half-rack width audio interface that includes two BNC SDI Inputs, two BNC SDI outputs and a pair of 100Base-T Ethernet connections for network connectivity. PoE (Power over Ethernet) from the network switch can be used as a backup for the internal auto-ranging power supply.
Loudness, spectral balance and image shifts are controlled while preserving more of the original content than previously possible. AERO.x is also compatible with Dolby Evolution, part of its new Intelligent Media Framework.
