Hertz HMD8DSP 8-Channel D-Class Marine Amplifier With DSP

New Highs of Listening Pleasure During Navigation

8 CH Marine Amplifier With DSP
The HMD8 DSP, powered by Hertz Marine DSP technology, rich new highs of listening pleasure during navigation. DSP user friendly PC-Software interface make the setup process a breeze, exploiting every single pills of performance from the installed speaker system.

The amazing power of 8 * 85 W or 4 * 260 W (RMS@ 4Ω) gives the HMD 8DSP the capability to drive with authority the complete speaker system generating tons of crystal clear SPL up to 3 different zone of the vessel. "Power for the Waves” design philosophy features a sturdy enclosure made of extruded aluminum with an anti-corrosion treated PCB to ensure years of listening pleasure in open water.

Features:

• Built in DSP, Hertz marine DSP technology allows you to move freely in the boat preserving a perfect surround effect, even with outdoor listening
• Multi Zone Setup, Hertz Marine DSP optimizes acoustic performance for each of the 3 configurable listening zones, regardless of where the speakers are installed and the point of the passenger within the zone, maximizing listening pleasure while cruising
• Crossover Filter; Filter Type: Full / High pass / Low pass / Band pass. Filter model and slope: Butterworth, Linkwitz-Riley, Bessel, Chebyshev, QLP quasi-linear phase
