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.
The name “ARC” – which stands for “Automatic Realtime Control” – provides a good clue as to what it is: A realtime television loudness processor featuring APTO®, our latest loudness adaptation algorithm.
Most of the television processors in the Linear Acoustic lineup are designed to process stereo and 5.1-channel audio, upmix 2-channel audio to 5.1, insert audience measurement watermarking, handle Dolby® coded audio, and insert local audio sources such as EAS. They also use multiband processing to help mitigate spectral inconsistencies and provide a consistent-sounding output.
In contrast, we designed ARC to simply and effectively process two 2-channel mono or stereo PCM programs, making it ideal for stereo-only channels in the U.S. as well as regions where support for 5.1-channel and coded audio is not required. The ATPO algorithm does not employ multiband processing, so the output audio is spectrally identical to the source material. ARC also provides the ability to easily set a LUFS/LKFS output target loudness value and maximum true peak levels.
ARC offers SDI, AES-3, and AES67 I/O, making it equally at home in today’s facilities as well as forward-looking SMPTE ST 2110 installations. Dual internal redundant universal auto-ranging power supplies ensure reliable operation anywhere in the world.
