The hd P18
is from an acoustic point of view identical to the hd Sub18
with the difference that the hd P-Series
houses the high-end hd MultiDSP and powerful Class-D amplifiers in the same housing and thus becomes the basic building block for every mobile Plug & Play system. This new DSP platform now enables all processing and control functions of large sound systems in easy-to-use plug & play active system.
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. A well-readable 4-line LCD display with 3.2″ screen size and 5 navigation buttons on the hd P18 enable easy and intuitive operation of all functions, as well as the loading of factory or user presets directly on the device without a PC.
All functions are clearly arranged via the USB interface and remote control software hd LevelZ. 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. In addition, the new and easy-to-use hd LevelZ PC remote software provides even more detailed information on individual requirements and an unlimited number of user presets and configurations.
18″ long-excursion speaker for controlled, punchy bass.
The hd P18 Active System Subwoofer is a compact, easy to carry and powerful subwoofer in bass reflex tuning. 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.
Class D amplifier technology of the latest generation.
The 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.
Perfect system thinking and unlimited flexibility.
Thanks to the hd P18 active system subwoofer, a long-awaited dream of musicians and sound systems becomes reality: one 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 optical requirements, you can connect small, medium or large mid / high speakers to the active bass and, if required, supply a complete PA including two monitor ways with 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.
The hd MultiDSP open architecture platform guarantees perfect control over all relevant system components using the easy-to-use, windows based hd LevelZ
remote software. This new DSP platform now enables all the processing and control functions of large sound systems in easy-to-use plug and play device.
The input section includes a routing matrix, a function generator (sine and noise generator), and 16 input channel IIR filters each, which can be configured as variable highpass / lowpass / allpass / peak / shelf / notch filters, and a 384 taps FIR filter. There are 16 IIR filters per output channel that can be configured as variable highpass / lowpass / allpass / peak / shelf / notch filters, 384 taps FIR filter, 100 ms delay, 180° phase inversion, peak limiter, RMS limiter, gain and mute available.
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. With the software, the individual requirements can be discussed in more detail and unlimited user presets and configurations can be managed.
