hd P18

On the rear panel there are level meters for each input and output channel, as well as a USB interface for setting and managing all audio parameters via PC. The extremely powerful DSP offers FIR and IIR filters for the exact adaptation of the PA system to the respective application. The input section includes a routing matrix, a function generator (sine and noise generator) and a freely configurable equalizer per input channel with 16 IIR filters and a 384 taps FIR filter. Each output channel has 16 IIR filters, 384 taps FIR filters, 100 ms delay, 180° phase reversal, peak limiters, RMS limiters, gain and mute.

There are 20 factory presets for all Harmonic Design speaker system configurations stored for direct recall to the device so that it can always be reset to a defined default state of the system. This guarantees highest reliability of the connected speakers and ensures a very dynamic and linear sound. For user-specific settings, another 20 freely configurable user presets are available to save and manage individual configurations. The hd P18’s easy-to-read, 4-line LCD display with a 3.2-inch diagonal screen and 5 navigation buttons enables simple, intuitive operation of all functions, as well as direct loading of factory or user presets without a PC.

All functions are clearly accessible via the USB interface and the hd LevelZ remote control software. This makes it possible to adapt the PA system to the changing requirements from day to day in the shortest possible time and makes the usual complete system change, for a small or large event, superfluous. Additionally, the new, easy-to-use hd LevelZ remote PC software allows you to address individual requirements in greater detail and manage an unlimited number of user presets and configurations.

The 18-inch long-throw loudspeaker provides controlled, powerful bass.
The hd P18 System Bass is a compact and powerful subwoofer with bass reflex tuning that is easy to transport. The specially developed 18″ long-excursion chassis with 5″ voice coil on fiberglass carrier allows an extreme excursion of ±30 mm. Through a ventilation at the pole piece and at the spider, the heat development of the coil is optimally dissipated. Therefore, an extremely high continuous power handling capacity of 1800W / 7200W is possible. The lower heat development also means increased reliability and reduced thermal stress on the voice coil. Excellent dynamics and dry bass reproduction at incredible pressure is the result.

The latest generation of Class D power amplifier technology.
This integrated digital power amplifier is equipped with the latest Class D technology. They are designed to meet the highest audio quality and reliability requirements in fixed installation projects and mobile applications. Low weight and compact dimensions, excellent sound and very high efficiency. Due to the extreme efficiency, the heat generation is absolutely minimized compared to conventional analog amplifiers. The power amp needs less cooling and works permanently in the safe area. The power amplifiers incorporates a state-of-the-art, high-efficiency switching mode power supply that can deliver full performance even under difficult grid conditions, such as undervoltage during live events caused by long power lines, and far superior to conventional power supplies with universal operating ranges from 95V to 265V. To play a sound event as realistic as possible, a large headroom is required. With an extremely high power of over 4000W / RMS we offer the highest dynamics for a natural and accurate reproduction.

The perfect system concept with limitless flexibility.
Thanks to the hd P18 system bass, the long-awaited dream of musicians and sound reinforcement companies has become a reality—one system for all! With only one hd P18 it is possible to drive two or four top cabinets or column speakers in addition to another passive hd Sub18. And it goes even further: The powerful amplifier allows you to adapt the active system to constantly changing sound requirements. Depending on the size of the room and the required optics, you can connect small, medium, or large mid-high speakers to the active bass. If necessary, you can also supply a complete PA system with two monitor paths and two hd P18. The DSP always guarantees optimum sound at all levels and highest operational reliability. The active system saves a lot of weight, cargo space and set-up time. In addition, the Plug & Play system minimizes cabling and thus potential sources of error.
