Television Loudness Processor
INTRODUCTION
Congratulations on your purchase of the Linear Acoustic ARC!
ARC – which stands for "Automatic Realtime Control" – 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, important for meeting
certain loudness recommendations and regulations.
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.
