D*AP LM4 incorporates Version II of the company’s Level Magic™ adaptive loudness algorithm, which is compliant with all current broadcast audio loudness recommendations including ITU.1770 (versions 1 and 2), ATSC A/85, ARIB TR-B32 and EBU R128. Based on a Multi-Loop dynamic range control principle where slow changes (AGC), fast changes (Transient processing) and look ahead true peak limiting are handled simultaneously, LEVEL MAGIC™ offers level management with exceptionally high audio quality and without coloration, pumping, breathing, distortion or modulation effects. LM4 focuses on automatic and adaptive loudness control and sound processing for up to four channels of audio. All system parameters are remotely accessible allowing the unit to be integrated and remote controlled by broadcast control or scheduling systems via HTTP, emBER, SNMP or even simple GPI/O’s. A web interface allows easy and intuitive set up and configuration. Audio I/O‘s range from: on board AES I/O to optional 3G/HD/SD SDI I/O or even analog I/O. All interfaces support power fail bypass as standard. With optional redundant PSU the unit ensures maximum operational security.
