French loudspeaker manufacturer Amadeus has launched its PMX D series of self-powered active speakers, featuring built-in 24/96 DSP and analogue, AES3 and Dante inputs.
The series includes three different models, containing 8, 12 or 15-inch coaxial drivers and can also be used in touring applications as a stage monitor.
The PMX D Series incorporates a newly refined Dante I/O section, offering options for full integration with leading third-party networking. Audio signals are selectable from one channel of analogue, two channels of AES3 digital, and two dual redundant Dante networked digital inputs.
Michel Deluc, Amadeus' director of research and development, says, "We were among the first manufacturers of electroacoustical equipment to look into audio transfers over Internet Protocol. We are committed to minimising latency as well as unnecessary AD/DA conversions that impact signal quality. This started ten years ago, the year we wrapped up development of our first line of bi-amped coaxial systems featuring EtherSound I/O, which was designed for the French Institute for Research and Coordination Acoustic/Music. The technological gains offered by the Dante protocol and its widespread adoption by professionals led us to consider its implementation within our systems."
The PMX D Series is bi-amplified using two dedicated high resonance digital amplifiers, with each amp delivering 400W under 8 ohms for the PMX 8 D, and 1500W (LF) + 400W (HF) for the PMX 12 D and PMX 15 D systems. These PPM-PWM fixed frequency class-D amplifiers are equipped with a high efficiency switched mode power supply.
Each speaker channel controlled by a 64-bit digital processing unit capable of a 118 dB dynamic range. Each of these on-board DSP units include a module dedicated to managing core system parameters including system EQ, time alignment between sections, limiting, and transducer thermal protection.
