Linear Acoustic AERO.2400 DTV Audio Processor

Linear Acoustic AERO.2400 DTV Audio Processor

High quality, compliant audio with a front panel GUI.

Like AERO.200, AERO.2400 hosts one or two AEROMAX® processing instances in your choice of AMX5.1 (5.1+2+2), AMX2.0 (2+2+2), or AMX 5x2 (2+2+2+2+2) configurations (a minimum of one is required) plus upmixing/downmixing via our UPMAX®-II algorithm - but adds the flexibility and convenience of a full color display, menu navigation controls, and a headphone output to the front panel.
 
Optional Dolby® Digital Plus transcoding provides for decoding of Dolby Digital/Dolby Digital Plus content to PCM audio for loudness processing and encoding to Dolby Digital/Dolby Digital Plus for transmission.
 
I/O includes de-embedding and re-embedding of up to 16 pairs of 3G/HD/SD-SDI audio and eight pairs of AES3 audio.
 
Support for SAP/DVS, EAS, local emergency audio, local voiceover, and optionally, Audio Description (warble tone) functionality is included. CrowdControl™ is standard for increased dialogue intelligibility.
 
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.

AERO.2400 offers our industry standard, no-compromise AEROMAX television loudness control and UPMAX-II upmixing/downmixing algorithm in a 2RU package.

The extra 1RU of height compared to AERO.200 makes room for an additional four audio pairs of AES3 I/O. It also allows us to include a full color front panel display, menu navigation controls, and a headphone output to adjust or monitor processing locally, though our NfRemote TCP/IP remote control software can also be used to provide control over all system settings and processing parameters remotely.

AERO.2400 can host two processing instances, both with ITU- and EBU-compliant loudness metering and logging.

It also offers reporting of physical I/O details, power supply status, and environmental health. The remote application can deliver remote audio, up to 5.1 channels, so the user can audition signal quality anywhere link bandwidth permits. An HTTP server is also 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 all I/O maintain signal continuity and dual auto-ranging power supplies enable redundancy and worldwide compatibility.

Designed and assembled in the USA, AERO.2400 is a solid investment in performance and flexibility today and in the future.
