AERO.ONE OVERVIEW {LEGACY PRODUCT}™ accepts baseband audio via AES (8 channels) or HD/SD-SDI (16 channels) I/O in a 5.1+2 channel configuration. It includes AEROMAX® processing, dual UPMAX® upmixing engines, and a downmixed output.

It can be optionally configured with Dolby Digital (AC-3) and Dolby Digital Plus encoding and SNMP monitoring.

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 1RU is a solid and proven performer.







  • Linear Acoustic AEROMAX loudness and dynamics control

  • UPMAX upmixing with AutoMAX-II™

  • 5.1+2 channel configuration

  • Available Dolby Digital (AC-3) and Dolby Digital Plus encoding

  • Available SNMP monitoring


Processing uses the renowned AEROMAX processing algorithm. This multistage adaptive wideband and multiband loudness and dynamic range control delivers audio that is both compliant and pleasing to the viewer.



2-channel to 5.1-channel upmixing is provided by the Hollywood-approved UPMAX algorithm which provides a compelling 5.1-channel audio experience while remaining completely downmix compatible. includes the AutoMAX-II auto-detection algorithm to smoothly and automatically bypass upmixing when 5.1-channel audio is applied.



Metadata can be applied, if available, via the VANC space of an applied HD-SDI signal or from a standard serial input for control of upmixing and processing functions. Extensive protection is provided to protect viewers from the audible effects of incorrect or missing metadata.
