AERO.2000 In Depth

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 including N2, N6, and CBET. AERO.2000 precisely inserts these signals for maximum code recovery – after audio decoding and processing and before transmission encoding.
