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/SD-SDI I/O, it offers 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.

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.



Nielsen Encoding

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.
