TC Electronic Loudness Pilot overview

  • 1Description

The TC Electronic Loudness Pilot AES Balanced is a broadcast transmission audio processor that provides dual-stereo and dual-mono loudness management to help broadcasters with their loudness responsibilities for TV, radio, and mobile applications. It employs a high-resolution ALC2 loudness control algorithm, which delivers high-quality audio with ultra-low latency, while allowing you to stay compliant with broadcast standards and legislation at all times.

The Loudness Pilot AES Balanced is designed for TV broadcasters who prefer to pass only the audio signal through their loudness management system rather than their entire SDI signal. It offers a total of sixteen physical channels of balanced AES I/O on D-Sub connectors, with the first eight channels active by default. Should you need to use additional channels, a license for activating channels 9-16 is available separately.

The proprietary DICE core digital I/O engine features JET technology, which helps reduce incoming jitter to a near-unmeasurable level. Audio sync locks quickly for glitch- and artifact-free transmission, while the Freewheel "safety belt" function keeps the unit running at the "last good sync source rate" when the source is lost.

Audio loudness is measured at the input as well as the output of the Loudness Pilot. In between, the high-resolution ALC2 algorithm handles everything regarding loudness including automatic loudness correction, true-peak limiting, lip-sync delay with look-ahead capability, all in one single process and for a multitude of broadcast platforms. The unit comes with ready-to-use presets based on international standards.

The built-in 3G transmission card can run two ALC2 algorithms, allowing loudness processing for two TV channels or two languages simultaneously. It also provides loudness control for multiple platforms simultaneously, delivering for both HDTV and mobile applications in real time. The auto input switching function enables seamless fallback to a secondary source when the primary source is unavailable, and can switch over to a broadcast emergency channel when audio is detected on it.

The Loudness Pilot AES Balanced features a full, dual-redundancy setup with dual fans, dual fuses, and dual power connectors, which you can use with independent power sources. In case of an emergency, the relay bypass passes your stream directly from input to output, ensuring a non-stop performance.

This fit-for-purpose unit offers the option to add optional TC Electronic software processors including aNorm adaptive normalization loudness processing and the LM2 Loudness Radar meter, which gives you a complete loudness landscape overview at a glance. The Loudness Pilot is housed in a compact, 1 RU enclosure to help you save space in your equipment room. Included are two power cords and a USB memory stick with the TC Icon Software and Loudness Pilot Software for Mac and Windows.

Note: Operating Loudness Pilot requires a TC Icon remote (available separately) or a computer running the included TC Icon software for Mac and Windows.

ALC2 Loudness Processing

Key Features
  • ALC2 is the "heart and soul" of Loudness Pilot
  • High-resolution, low-latency loudness control algorithm
  • Corrects substantially when needed, subtly when appropriate, and leaves your audio untouched when it is already normalized
  • Automatic loudness correction
  • Look-ahead lip-sync delay
  • True-peak limiting
Auto Input Switching
  • Dual-language switching: Auto input switching enables seamless fallback switching to language B if language A is not available
  • Emergency switching: Set up Loudness Pilot to automatically switch to an emergency channel, if there is audio present on that channel

Dual Redundancy

  • Offers robust redundancy and reliability needed for mission-critical live applications
  • Dual power supplies for independent power sources
  • Dual fuses
  • Dual low-noise fans

Relay Bypass

Complete relay bypass passes your stream directly from input to output for non-stop performance no matter what happens

Dual Language/Dual TV Channel Correction

Loudness Pilot is a dual stereo and dual mono processor, allowing loudness processing of two TV channels or two languages simultaneously
