The DP 4.400 from Hertz is a 4-channel amplifier with an output power of 75 W x 4 at 4Ω and 105 W x 4 at 2Ω at 1% THD. It supports a frequency range of 10 Hz to 50 kHz and features Class-AB amplification. The amplifier is High-Resolution Audio certified and offers an efficiency of 60%. The signal-to-noise ratio is 101 dBA. Its power supply ranges from 6.5 to 16.5 VDC, and it has a damping factor of 130 at 1 kHz, 1 W power.

Wie sieht die Ausgangsleistung des DP 4.400 Verstärkers bei verschiedenen Ohm aus?

The DP 4.400 delivers 75 W x 4 channels at an impedance of 4 Ohms and 105 W x 4 channels at 2 Ohms at 1% THD. At 4 Ohms, the 3-channel output powers are 75 W x 2 plus 210 W x 1. When operating with 2 channels at 4 Ohms, it provides 210 W x 2. When the amplifier is operated at 14.4 VDC and 10% THD, the output powers increase to 90 W x 4 at 4 Ohms and 125 W x 4 at 2 Ohms, with 250 W x 2 in two-channel use at 4 Ohms.

Welche besonderen Merkmale bietet der DP 4.400?

The DP 4.400 from Hertz features its fully bridgeable Class-AB amplification, which is stable at two Ω. The amplifier has automatic on and off switching as well as universal compatibility with an operating supply voltage of 9 to 16.5 V and a high input sensitivity. On the input side, there are preamplifier and speaker inputs. The built-in bass boost function at 50 Hz allows for an amplification of 0 to 9 dB. Additionally, integrated crossovers are available with an adjustable range from 50 to 4000 Hz, offering both high-pass and low-pass filter options.

Wie effizient ist der DP 4.400 Verstärker?

The DP 4.400 amplifier from Hertz achieves an efficiency of 60%. Efficiency in an amplifier means how well the device converts electrical power into acoustic power. For Class-AB amplifiers, an efficiency of 60% is relatively high, which means that the amplifier generates less waste heat for a given power consumption and delivers more power to the speakers. This is particularly important when the amplifier is used in a car, as high efficiency reduces the load on the onboard network while ensuring better sound quality.

Welche Frequenzweichenoptionen bietet der DP 4.400?

The DP 4.400 offers versatile crossover options for audio signal adjustment. It features high-pass and low-pass filters for front and rear channels, which can be set within an adjustable range of 50 to 4000 Hz at 12 dB/octave. This allows the sound reproduction to be precisely tailored to the respective speakers, which is particularly important in multi-channel systems in vehicles. This enables optimized playback of both low and high-frequency signals, resulting in a clearer and more precise sound experience in the car.

Was bedeutet die High-Resolution Audio-Zertifizierung des DP 4.400?

The High-Resolution Audio certification of the DP 4.400 by Hertz ensures that the amplifier is capable of elevating audio signals beyond the standard CD quality range. With a frequency response of 10 Hz to 50 kHz, it can capture the nuances of audio data provided by lossless formats and high-resolution files. This makes the amplifier a solution for audio enthusiasts who want to enjoy the best possible sound experience in their vehicles by listening to an incomparably detailed and rich soundscape.

Ist der DP 4.400 von Hertz stabil bei 2 Ohm Last?

Yes, the Hertz DP 4.400 amplifier is stable at a load of 2 ohms. This means that the amplifier offers enhanced flexibility for various speaker setups. When using speakers with a lower impedance like 2 ohms, the amplifier can output more power, improving audio quality. For four-channel configurations, it delivers 105 W x 4 at 2 ohms. This stability ensures that even at low impedances, the sound fidelity and performance of the amplifier are maintained without overheating issues or distortions.

Wie hoch ist das Signal-Rausch-Verhältnis beim DP 4.400?

The Hertz DP 4.400 amplifier offers an impressive signal-to-noise ratio (SNR) of 101 dBA. A high SNR means that the audio signal output by the amplifier is much louder than the background noise level, resulting in clearer, more precise audio output. An SNR of 101 dBA is particularly noteworthy and indicates that the amplifier is designed to provide high-quality, low-noise sound reproduction. This is crucial for discerning music lovers who appreciate fine details in their music and desire lossless sound quality.

Kann der DP 4.400 Verstärker automatisch ein- und ausgeschaltet werden?

Yes, the DP 4.400 from Hertz features an automatic on and off function, based on the entertainment electronics interface SPK-IN (suitable only for BTL radios). This functionality ensures that the amplifier is activated or deactivated without manual operation of the sensor. With a trigger level of 1.5 VDC, the amplifier is automatically turned on when an audio signal is detected and turns off as soon as no signal is present. This eliminates the need for additional control lines and makes integration into existing systems incredibly simple.

Welche Spannungsversorgung benötigt der DP 4.400 von Hertz?

The DP 4.400 amplifier from Hertz requires a power supply in the range of 6.5 VDC to 16.5 VDC for its operation. The nominal voltage of the power supply is 11 to 15 VDC, protected by 2 x 25 A fuses. At idle current, it consumes 0.85 A, while the standby power consumption is only 10 µA, which is advantageous for use in vehicles to preserve the battery. With a minimum load impedance of 2 Ω for all 4 channels, the amplifier is well-equipped for multichannel configurations and offers an outstanding audio experience.

Alpine tube 12 bazooka , Un sacré caisson de basses ,

Un sacré caisson de basses , j'ai eu un 46 cm killer 454 de l'époque année 90 , qui tapait vraiment bien , mais ce tube est bien plus fort et plus ample, toutes les basses passent sans problème, avec une télécommande à réglage multiples taramps eq bass , et un ampli Machete de masori , le couple est parfait, personnellement j'en ai deux tubes et ça donne énormément, avec l'ampli 2 x 530 en 4 ohms . Parfois le plus simple est bien meilleur et plus durable .

X-10 v3 d2

Hallo. Sehr freundlicher Kundenservice und schnelle Auftragsabwicklung. Der Lautsprecher ist brandneu und unbenutzt. Ich habe ihn vor einiger Zeit gekauft, aber erst kürzlich das Gehäuse fertiggestellt. Die Parameter entsprechen den Herstellerangaben: 42,5 Liter Nettovolumen, abgestimmt auf 32 Hz und 21 mm starkes Sperrholz. Ich hatte noch nie einen 10-Zoll-Lautsprecher und wusste nicht, was mich erwartet, aber das Ergebnis hat meine kühnsten Erwartungen übertroffen. Der Bass aus einem so kleinen Lautsprecher in einem so kleinen Gehäuse ist einfach unglaublich. Um den X-10 zu kaufen, habe ich meinen DD 712f in einem 70-Liter-Gehäuse verkauft, und der war ein Volltreffer. Der Sundown ist in jeder Hinsicht besser. Ich kann diesen Lautsprecher und den Händler, bei dem ich ihn gekauft habe, wärmstens empfehlen. Beste Grüße.

Top Upgrade für Canton System

Ich habe den Woofer in meinem Skoda Octavia 3 mit Canton Soundsystem eingebaut.
Der Einbau war Plug & Play, alles passt perfekt ohne Anpassungen.
Im Vergleich zum originalen Canton Subwoofer spielt dieser deutlich stärker, präziser und mit mehr Druck.
Ich kann den Woofer jedem empfehlen, der mehr Bass aus dem Canton-System herausholen möchte – lohnt sich absolut!
