The hd P-Series loudspeakers are from the acoustical view equivalent to the hd Sub-Serieswith the difference of the added high-end hd MultiDSP as well as a powerful Class-D amplifier in the same enclosure. They are the basis of every mobile self-powered Plug&Play system. The new DSP-platform allows intuitive access to all processing and control features well-known from large format touring loudspeaker systems in an easy to use plug&play active loudspeaker system. LED-level indicators for every input and output channel are located on the rear connection and control panel, as well as an USB interface for managing and setting all audio parameters via a PC. The extremely powerful signal processor offers FIR- and IIR-filters for exact adjustments and optimizations of the sound system to the respective application. The input section includes a routing matrix, a signal generator (sine and noise generator) and a free configurable EQ with 16 IIR-filters as well as a 384-tap FIR-filter on each input channel. A free configurable EQ section with 16 IIR-filters as well as an additional 384-taps FIR-filter, up to 100 ms delay, phase reverse, peak- and RMS-limiter, gain and mute are available for each output channel. There are 20 factory presets for all Harmonic Design loudspeaker system configurations for direct retrieval on the device, that always a defined basic state of the system may be recalled. All necessary system parameters and settings are restored as well, to ensure maximum reliability, performance and safety of the connected loudspeakers. Further 20 freely configurable user presets are available for user-specific settings to store and manage individual system configurations. A well-readable 4-line LCD display with 3,2” screen diagonal and 5 navigation buttons allow an easy and intuitive control of all functions of the hd P18 models and a quick access to load factory and user presets directly on the device without the need for a connection to a PC. The direct access via navigation buttons or display at the connection panel on the hd P12stereo is reduced in terms of space. By using the USB interface all control and managing functions may be accessed without limitation via a PC and the easy to use remote software hd LevelZ. The quick access directly at the rear of the powered subwoofers as well as the extremely versatile hd LevelZremote control software makes it possible to adapt the existing PA system to the changing requirements from day to day in the shortest possible time. Furthermore, the mostly common complete change of the PA system from a small to large application is no more need. The multichannel Class-D amplifier delivers up to 2.500W on the output channel and supplies ample continuous and peak power to the drivers. They have been invented to fulfill the highest demands on audio quality and reliability for mobile applications. The switching mode power supply with PFC has a large operating range from 95V-265V AC 50Hz/60Hz and is able to deliver the power even under worst circumstances e.g. undervoltage or overvolatage.
