Amadeus Audio has announced the PMX D Series active speakers, featuring built-in 24/96 DSP, and analogue, AES3 and Dante inputs.

Three models, containing 8-, 12- or 15-inch coaxial drivers address a range of sound reinforcement applications in concert halls, auditoria, conference rooms and theatres. Designed to be included within fixed or long-lasting installations, each PMX speaker system can also be used as a stage monitor.

All PMX D Series systems use coaxial neodymium transducers, combining the features of cone speakers and compression drivers in a one-piece, point-source system. The PMX 8 D system hosts a coaxial driver with 8-inch, and 1-inch tweeter with compression driver. The PMX 12 D and PMX 15 D systems host a coaxial driver with 12-inch, or 15-inch woofer respectively, and 2-inch tweeter with compression driver. Each of the new PMX D Series speakers integrates with the forthcoming ML 12 D, ML 15 D and ML 18 D subwoofer systems.

The PMX D Series is bi-amplified using two dedicated high-resonance digital amplifiers, with each amp delivering 400W into 8Ω for the PMX 8 D, and 1.5kW (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 is 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. This level of control makes the PMX D Series fully protected and able to operate at the full extent of its abilities. Each loudspeaker also integrates two digital inputs/outputs conforming to the AES3 digital audio data transfer standard. These are coupled with a high resolution 24-bit/96kHz converters placed as close as possible to the electronic amplifiers, thus working in perfect combination with them.

The PMX D Series incorporates a newly refined Dante I/O section, offering options for full integration with 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. Input signals are individually selectable for each channel. As the first company to include Audinate's Dante technology in a high-end active coaxial speaker series, Amadeus joins 275 other manufacturers using Dante. Each Dante Ethernet RJ-45 network input allow remote control of the PMX D processor for an optimal adjustment via dedicated software to the acoustical properties of the listening space. The software is an App that runs on Macintosh, Apple iPad and Windows computers.

PMX D speakers ship with a highly resistant black (water-soluble) paint finish, but are also available in alternative standard colours. Every PMX D Series speaker can also be ordered in a ‘made-to-measure’ finish, based on registered or non-registered colours and/or materials. To offer more possibilities, the cabinet and the acoustical fabric covering the front grill can each have a different colour.

The PMX D Series is now available from licenced Amadeus distributors, and dealers throughout Europe and Asia.

‘We were among the first manufacturers of electroacoustical equipment to look into audio transfers over internet protocol,’ says Amadeus R&D Director, Michel Deluc. ‘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.’
