Linear Acoustic ARC Next Generation Television Loudness Processor Overview

The Linear Acoustic ARC is a budget-friendly, easy-to-use, 2-channel television processor specifically designed for regions and applications that do not require support for multi-channel, coded audio, but where no-compromise audio quality is valued. 


 

Linear Acoustic ARC Next Generation Television Loudness Processor Features

  • Audio processing using the Linear Acoustic APTO® loudness adaptation algorithm

  • Compliance for any loudness recommendation or regulation including EBU R 128 and ATSC A/85 (CALM)

  • Processing for two PCM stereo or mono program streams • Ability to specify target loudness and True Peak values

  • 3Gb/s HD/SD-SDI and AES-3 I/O

  • AES67 I/O supports SMPTE ST 2110-30 workflows

  • SDI video delay to compensate for latency and ensure A/V sync
  • Rolling 6-hour loudness logging for each program

  • Separate loudness event log to easily identify loudness issues plus system event log

  • System event log

  • SNMP

  • Dual internal redundant auto-ranging power supplies

  • Browser-based remote control

Linear Acoustic ARC Next Generation Television Loudness Processor In Depth

The Right Features at the Right Price

Until now, broadcasters looking for a straightforward, stereo, television processor had to make some difficult compromises.

Less costly solutions were budget-friendly, but the savings came at the expense of audio quality. Products that delivered excellent audio performance also included features such as support for multichannel, coded audio and audience measurement watermarking that simply aren’t required in many regions – and with a price tag that put them out of reach to smaller broadcasters. 

Linear Acoustic ARC eliminates that compromise by offering a 1RU DTV audio processor for two independent PCM stereo or mono program sources that delivers the viewer-pleasing audio upon which Linear Acoustic has built its reputation.

APTO Processing

ARC features the Linear Acoustic APTO loudness adaptation algorithm which carefully controls levels in a way that preserves transients, sonic image, and the artistic intent of the original audio source while still ensuring full compliance with any loudness recommendation or regulation including EBU R 128 and ATSC A/85 (CALM).

Simple, Straightforward Setup

Setting up ARC couldn’t be simpler: Select a suitable adaptation profile for your programming from the ample list of factory presets, adjust a single control to determine the amount of overall processing desired, set the desired loudness target, and walk away with confidence.

A front panel navigation cluster is used for initial setup, while a web-based, browser- and OS-agnostic remote user interface makes more detailed setup and monitoring easy and convenient on any computer or mobile device. A front panel color LCD display clearly shows audio levels and loudness information

Ready for Today, Ready for the Future

I/O includes AES-3, 3Gb/s HD/SD-SDI, and AES67, making ARC suitable for use in today’s typical broadcast facilities, but also compliant with SMPTE ST 2110-30.
