Ideally suited for stereo broadcast and production, the EASY LOUDNESS SDI audio processor is designed to ensure that audio levels and loudness are automatically kept under control – from program to program and day to day.

Featuring comprehensive Level Magic loudness control, fail over switching and true peak limiting for two independent stereo programs, sourced from SDI or AES.

Level Magic

Based on a unique multi-loop control principle, the Level Magic algorithm provides adaptive wideband loudness control with exceptionally high audio quality, without coloration, pumping, distortion or other modulation effects. Level Magic is designed to be audibly transparent and process adaptively with minimal user interaction. Level Magic is compliant with all current broadcast audio loudness recommendations based on the ITU-R BS.1770 standard as well as the derived recommended practices ATSC A/85, ARIB TR-B32, Free TV OP-59, Portaria 354, EBU R128 and more.

Loudness Measurement and Logging

For compliance with local regulations, loudness and true-peak levels can be measured and monitored directly from the web browser interface. Simultaneously all data is transmitted via Ethernet to the J*AM measurement and logging software (license option), providing comprehensive file logging, live monitoring, and offline analysis.

Fail Over

With its integrated failover system, EASY LOUDNESS SDI is able to switch to a backup signal path, in case the main feed gets lost. The AES stereo input can be used as a fallback input if the SDI signal is interrupted.

Easy Web Configuration

Enabling easy and intuitive setup and configuration from anywhere in your network, a browser-based web interface with a newly designed ‘home’ page allows for fast set-once-and-forget operation. Onscreen metering and measurements are available for easy reference and a dedicated ‘Mobile UI’ is tailored specifically for touch-screen, tablet, and smartphone access.

Physical Interfaces

EASY LOUDNESS SDI is fitted with a 3G/HD/SD SDI interface featuring video and audio delays, intelligent routing options, a test generator and full de-embedding and embedding of up to 16 audio channels. Additionally, a stereo AES interface with physical XLR and BNC (AES3id) connectors is installed. 

System Security

With dual redundant PSUs, automatic sync source switching, power fail bypass relays (audio and video) and SNMP monitoring, the unit ensures maximum operational safety.

System Integration

All system parameters can be remotely controlled via Ember+ control protocol enabling any broadcast automation system to fully operate and virtualize the device. A Snapshot functionality was developed for simple and easy loading of presets by GPI, network or physical Hotkeys (optional X*AP RM1).
