Linear Acoustic AERO.20 DTV Audio Processor

Linear Acoustic AERO.20 DTV Audio Processor, Cost-effective PCM loudness control without compromising quality

AERO.20 hosts a single AEROMAX® processing instance in AMX5.1 (5.1+2+2), AMX2.0 (2+2+2), or AMX 5x2 (2+2+2+2+2) configurations (user-selectable) plus upmixing/downmixing via our UPMAX®-II algorithm.

I/O includes de-embedding and re-embedding of up to 16 pairs of 3G/HD/SD-SDI audio and four pairs of AES3 audio.

Support for SAP/DVS, EAS, local emergency audio, local voiceover, and optionally, Audio Description (warble tone) functionality is included.

ITU-R BS.1770 and selectable EBU R-128 or ATSC A/85 metering and logging (including True Peak) is provided for all program outputs. NfRemote software is included for remote configuration, control and metering over an Ethernet connection, while a built-in HTTP server enables control of I/O, presets, and individual processing parameters using simple IP commands. Compensating video delay and dual redundant internal power supplies are standard.

• Linear Acoustic AEROMAX loudness and dynamics control

• UPMAX-II automatic upmixing and downmixing

• Single processing instance AMX5.1 (5.1+2+2), AMX2.0 (2+2+2), or AMX 5x2 (2+2+2+2+2) configuration (user-selectable)

• 16 audio pairs via dual 3G/HD/SD-SDI I/O with included video delay

• 4 audio pairs of AES3 I/O with reference input

• Dual auto-ranging power supplies

• Relay bypass of all I/O

• Comprehensive PC based GUI plus extensive TCP/IP and HTTP control

• Logging of loudness and True Peak data

The highest quality industry standard television loudness control has never been more affordable. AERO.20 is a full-featured audio processor specifically for PCM (non-coded) audio that uses the same AEROMAX processing engine as our AERO.200, AERO.2400, and other products. Add upmixing, downmixing, and ITU- and EBU-compliant loudness metering and logging and it’s easy to see why AERO.20 is such a powerful solution for nearly any application despite its low cost.

Comprehensive TCP/IP remote provides control over all system settings and processing parameters plus extensive loudness metering. It also offers reporting of physical I/O details, power supply status, and environmental health. The remote application also delivers remote audio, up to 5.1 channels, so the user can audition signal quality anywhere link bandwidth permits. An HTTP server is included for simple get/set control of all parameters and retrieval of status and logging information.

Constantly active logging captures 24 hour, 48 hour, and 7.5 day rolling weekly reports as well as specific time slots controlled by start/stop. Loudness measurements with multiple integration times as well as True Peak measurements are captured and available for download.

Failover bypass relays on AES and SDI I/O maintain signal continuity and dual auto-ranging power supplies enable redundancy and worldwide compatibility.

Designed and assembled in the USA, the lightweight and rugged single rack-unit AERO.20 is a solid investment in performance and flexibility.
