EASY LOUDNESS

Introduction

The EASY LOUDNESS is an entrance level processor that may be bought with a 3G/HD/SD SDI
or an AES67/Dante interface.
This manual refers to an EASY LOUDNESS equipped with a SDI interface.
The EASY LOUDNESS focuses on automatic and adaptive loudness management compliant with all current
broadcast audio loudness recommendations including ITU.1770 standards (revisions 1, 2 and 3) as well as
recommended practices ATSC A/85 (2011/2013), ARIB TR-B32, Free TV OP-59, Portaria 354 and EBU
R128. The EASY LOUDNESS features loudness normalization for up to two stereo programs of audio.
The Level Magic™ is based on a unique multi-loop control principle.
LEVEL MAGICII™
The algorithm offers adaptive wideband control with exceptionally high audio quality uncompromised
loudness management without any coloration, pumping, distortion or modulation effects by combining three
major gain changing elements:
· Transient Processor
· Adaptive AGC
· Distortion-free true peak limiter
System Integration
All system parameters are remotely accessible, allowing the unit to be integrated and remotely controlled by
broadcast control systems. This helps users to apply individual processing to their programs, which is a key
feature for well-managed loudness control.
Loudness measurement
To check compliance of programs with your local loudness regulations, the unit analyzes loudness and true
peak levels from input signals and may transfer the measurement data via Ethernet to an optional
measurement and logging software anywhere in your network. These measurements can be triggered by
automation systems via GPIs, via network or even manually on the X*AP RM1 remote panel.
The EASY LOUDNESS can also generate SNMP or GPI/O alarms in case pre-determined limits are
exceeded.
Web configuration
A web interface also allows easy and intuitive setup and configuration anywhere in your network.
Interfaces and system security
Audio I/Os range from one onboard AES I/O to either a 3G/HD/SD-SDI I/O including video delay or an
AES67/Dante AoIP interface. The SDI interface has a power fail bypass relay as standard. With redundant
PSU and SNMP integration the unit ensures maximum operational safety.
