ARC Television Loudness Processor
ARC TELEVISION LOUDNESS PROCESSOR OVERVIEW
Linear Acoustic® quality with the right features at the right price
Introducing Linear Acoustic ARC (Automatic Realtime Control), our next-generation television loudness processor featuring our state-of-the-art APTO® loudness adaptation algorithm.
The 1RU ARC processes two 2-channel stereo or mono programs and is designed for simple setup. Specify a target output loudness value, choose a processing profile, and walk away knowing your station is in compliance with all global loudness standards and recommendations, including EBU R128 and ATSC A/85.
ARC is ideally suited to regions and applications where multi-channel audio is not supported or required, and which require straightforward stereo loudness processing without the need for coded audio, audience measurement watermarking, external audio insertion, or many of the other advanced features found in our AERO-series processors.
Broadcasters on a budget no longer have to compromise between audio quality and affordability, as ARC delivers the viewer-pleasing audio for which Linear Acoustic has become famous, but at a very approachable price point.
ARC supports two independent audio programs via AES, SDI, and AES67 I/O, making it fully compliant with SMPTE ST 2110.
Its easy-to-use web-based user interface ensures a simplified remote experience on any device, browser, or OS. Loudness logging for each program is included for compliance verification as a .csv file.
