The Linear Acoustic AERO.2000™ provides all of the features and functionality of the AERO.100, but takes things a step further. Handling up to 16 channels of baseband or encoded audio via both AES or HD/SDSDI I/O, it offers AEROMAX® audio processing, upmixing, encoding, and metering for over the air, over the top, and mobile television broadcasts in a 2RU chassis with a front panel that includes a full-color screen, controls, and headphone output.
Base configuration includes a single processing instance in a 5.1+2+2 channel configuration, with or without Dolby® encoding and Nielsen® Watermark encoding. A second processing instance (5.1+2+2 or 2+2+2) with or without the Dolby and Nielsen options can be enabled at any time by simply entering a factory provided key.
Local audio insertion, SAP/DVS with downmix replacement, full-time downmix, and support for Audio Description (warble tone) is provided.
Failover bypass relays on all I/O maintain signal continuity and dual auto-ranging power supplies enable redundancy and worldwide compatibility.
Designed and built in the USA, the 2RU AERO.2000 combines performance, flexibility and convenience.
A full color front panel screen with rotary navigation cluster and headphone output allow for local set-up and adjustment.

Extensive TCP/IP remote control and HTTP control
Comprehensive TCP/IP Remote
Provides control over all system settings, processing and coding parameters plus extensive metering of signal presence, processing and coding activity, and audio loudness. System status reports physical I/O details along with system, power supply and environmental health. The remote application also delivers remote audio, including 5.1 channels, to the user so that signal quality can be auditioned anywhere link bandwidth permits. The built-in HTTP server provides for simple get/set control of all parameters and status.
Generates revenue-critical Nielsen NAES II and the new Nielsen Watermarks audience measurement codes. AERO.2000 precisely inserts these signals for maximum code recovery – after audio decoding and processing and before transmission encoding.
Linear Acoustic Intelligent Dynamics hybrid metadata processing is a patented hybrid of traditional multiband techniques and metadata. Because it is created during transmission encoding, this metadata requires no operator intervention or special tools and is a new version of the DRC part of the Dolby Digital encoder that has always been there. Except it is now effective and uncomplicated. Featured at no additional cost, Intelligent Dynamics is actually a combination of two revolutionary technologies.
How it Works
The first portion of Intelligent Dynamics is the Emmy® award-winning process developed by Linear Acoustic which generates new metadata dynamic range control via traditional processing techniques. This control can be set as permanent, reversible, or anywhere in between. This technology is already present in every AERO.100, AERO.1000, AERO.2000, AERO.asi and AERO.soft product.
The second portion of the process involves verifying and marking content as compliant upstream. This is accomplished using a portion of the new Dolby Intelligent Media Framework called Evolution which enables measurement and incorporation of authenticated loudness data within the audio at each stage of the content delivery chain from production onwards. Compliant programming can be passed through with minimal or no additional processing, while content that cannot be verified can still be made compliant.
Most current television audio processors control loudness by managing dynamic range in real time. This effectively manages “boundary issues” such as commercials that follow a quiet program segment, but also compromises the impact and excitement of intentionally dynamic scenes because all programming gets some degree of permanent correction.
Audio transmission formats such as Dolby Digital (AC-3) and Dolby Digital Plus (E-AC-3) already incorporate metadata dynamic range control (DRC) profiles, which can provide some control, but these profiles are not ideally suited for broadcast audio and often result in significant over and under processing if other metadata parameters are not correct.
Intelligent Dynamics overcomes these compromises and enables audio to be processed to the degree and permanence dictated by the programming itself. The content effectively and automatically controls the processing and eliminates the need for further downstream changes that could irreparably change it.
Consumers can now enjoy the benefits of audio that is tailored to their liking using existing Dolby Digital and Dolby Digital Plus decoders. From the default of controlled dynamic range for noisy environments and small television speakers to full dynamic range for well-produced programming and multi-channel home theater systems, Linear Acoustic Intelligent Dynamics delivers the best of both worlds without compromise.
