Frequently Asked Questions about HMD8 DSP 24V

What power does the HMD8 DSP 24V Amplifier from Hertz provide?

The HMD8 DSP 24V delivers an RMS power of 8 x 85 W at 4Ω or 4 x 260 W in bridge mode at 4Ω. When operated at 28.8 VDC, you get 130 W per channel at 2Ω. This makes it ideal for use on open waters, where high sound pressure and clear audio quality are required. However, note that the maximum power supply should be between 22-34 VDC. It is also interesting that the amplifier has a very low distortion factor of only 0.06% at 1 kHz, 4Ω, which leads to low-distortion audio playback.

How is the HMD8 DSP 24V designed regarding its power supply?

The HMD8 DSP 24V from Hertz is designed for an MPX power supply and operates in a range of 22-34 VDC, with the idle current at 0.96 A. Maximum everyday usability is ensured by the low power consumption in the off state of only 1.6 mA. In operation, the amplifier can consume up to 27.5 A at 14.4 VDC and 2Ω. Notably, the Remote-IN voltage of 6-34 V and the Remote-OUT voltage of 14-34 VDC allow for easy integration into various installations.

What audio specifications does the HMD8 DSP 24V have?

The Hertz HMD8 DSP 24V offers a signal-to-noise ratio of 100 dBA at the master input and 105 dBA at the optical input, both A-weighted at 1 V. The bandwidth ranges from 10 Hz to 22 kHz at -1.5 dB, which is ideal for high-quality audio applications. The distortion factor is only 0.06% at 1 kHz and 4Ω at 70% of the nominal value, indicating high processing quality. Noteworthy is the high damping factor of over 110 at 1 kHz, 4Ω, 2 VRMS, which leads to detailed control over speaker movement.

What filter types are integrated into the digital signal processor of the HMD8 DSP 24V?

The DSP supports various filter types, including full, high, low, and bandpass filters. Different models such as Butterworth, Linkwitz-Riley, Bessel, Chebyshev, and quasi-linear QLP phase are offered, each with slopes ranging from 6 to 60 dB/Octave. The crossover frequencies can be adjusted from 20 Hz to 20 kHz, allowing for precise sound adjustments. The phase control is adjustable from 0° to 180°. Whether you need applications with Peaking, High Shelf, Low Shelf, Notch, or All Pass, the DSP can be configured completely freely with up to 10 parametric and 10 graphic poles.

What are the dimensions of the HMD8 DSP 24V and how does that affect installation?

With a size of 238 x 49.5 x 155 mm (W x H x D), the HMD8 DSP 24V is compact enough to be mounted in tight installation areas and fits perfectly in typical spaces on boats. Its weight is 1.98 kg, which makes handling during installation easier. Make sure to install the device in a tamper-proof manner to prevent movement during operation. The robust aluminum housing provides protection and supports heat dissipation, but good ventilation should also be ensured to avoid overheating.

What features does the graphic and parametric EQ of the HMD8 DSP 24V offer?

The HMD8 DSP 24V from Hertz offers both graphic and parametric EQ modes. In total, there are 10 parametric poles with features such as Peaking, High Shelf, Low Shelf, Notch, and All Pass, with gains at ±12 dB and allowing a variable Q from 0.5 to 16.0. Additionally, there are 10 graphic poles that enable precise sound control across different frequency ranges. You can use three parametric poles per memory, which greatly simplifies the creation and retrieval of presets for different listening environments.

How well is the Hertz HMD8 DSP 24V suited for applications on open water?

The HMD8 DSP 24V is specifically designed for marine applications. Its housing is made of extruded aluminum and protects the corrosion-sensitive parts thanks to a durable circuit board, making it ideal for use in humid environments. The DSP technology ensures robust audio performance and adaptability in open listening areas, which is particularly advantageous on watercraft. The amplifier is also flexible in terms of power supply with an operating voltage of 22-34 V, allowing it to meet variable requirements on different boats.

What type of loads can the HMD8 DSP 24V drive?

The Hertz HMD8 DSP 24V can handle loads of up to 2Ω across 8 channels, which means you can operate various speaker model configurations to achieve maximum volume and clarity. In bridged mode, it drives up to 4Ω. This means you can configure 4 stereo pairs or 4 bridged outputs. This allows for versatile adaptation to your audio configuration on your boat. The power characteristics are designed for demanding audio applications and offer considerable flexibility for numerous audio requirements.

How can time alignment be applied with the Hertz HMD8 DSP 24V?

The HMD8 DSP 24V features a variable time alignment distance of 0 to 54 inches and a time-step based delay of 0 to 15 ms in 1 cm increments, allowing for precise tuning of the sound to the listening position. This feature is particularly useful for compensating for time differences and creating an optimal soundstage. Especially in maritime applications, where speakers are unevenly distributed, this function makes a significant difference. It allows the sound to be directed precisely to specific points in the room, greatly enhancing the listening experience.

What phase control options does the HMD8 DSP 24V offer?

The phase control of the Hertz HMD8 DSP 24V is freely adjustable between 0° and 180°, allowing you to correct phase shifts and precisely align sound waves. This adjustability is particularly helpful in complex audio setups where different speakers work together. With precise adjustability, the phase angle of the speakers can be matched to achieve seamless playback across different frequency ranges. By targeted phase adjustment, you can reduce unwanted acoustic anomalies such as cancellations.
