Frequently Asked Questions about Cento CP 4.800

What power does the Cento CP 4.800 provide at 4 Ohms?

The Cento CP 4.800 from Hertz delivers an RMS output power of 110 W per channel at 4 Ohms with 4 channels. In bridge mode, where two channels are combined into one, the amplifier reaches an output power of 380 W at 4 Ohms. These specifications make it a powerful option for Hi-Fi audio applications in cars. The high efficiency of 85% also ensures that the amplifier operates with minimal heat generation at this power setting, which increases reliability and longevity.

What is the efficiency of the Cento CP 4.800 amplifier?

The Cento CP 4.800 features an impressive efficiency of 85%. This means that a large portion of the electrical energy consumed is converted into sound output, while only a minimal amount is converted into unwanted heat. This is particularly relevant for mobile audio applications, where efficiency is closely linked to the maximum achievable volume and minimizing heat generation. With a nominal supply voltage of 11-15 VDC and a total current consumption of 32 A at maximum music power, this amplifier ensures both power and energy efficiency in a compact design.

What are the minimum load impedances supported by the Hertz Cento CP 4.800?

The Hertz Cento CP 4.800 can be flexibly operated with different load impedances. In 4-channel mode, it supports a minimum impedance of 2 Ohms per channel, which is ideal for high currents and maximum output power. In 3-channel operation, the configuration is 2 Ohms for the two front channels and 4 Ohms for the rear channel. Finally, the amplifier can be operated in 2-channel mode at loads of 4 Ohms, with each channel delivering 380 W. This versatility in impedance support allows for flexible installations and optimal sound.

What does the Cento CP 4.800 offer in terms of crossovers?

The Hertz Cento CP 4.800 is equipped with adjustable crossovers that allow for precise tuning of the frequency range for each channel. This is crucial for optimizing the audio output to meet the specific requirements of the speakers in a car. The detailed tuning enables achieving the desired sound characteristics while minimizing distortion. With these adjustable crossovers, seamless integration of subwoofers and bridging channels can be achieved, creating a balanced and nearly lossless sound.

What voltages does the power supply of the CP 4.800 support?

The power supply of the Hertz Cento CP 4.800 supports a wide range of voltage requirements, from an operating voltage of 9 to 18 VDC. This allows for flexible integration into various vehicle models with different electrical systems. The nominal voltage is between 11 to 15 VDC, regulated by a 40-amp fuse, ensuring the safe and stable operation of the Amplifier. With a no-load current of only 1.15 A and a standby power consumption of 4.2 μA, the Amplifier is not only powerful but also efficient in energy consumption.

What is the signal-to-noise ratio of the Cento CP 4.800?

The Cento CP 4.800 has a signal-to-noise ratio of an impressive 101 dBA, A-weighted at 1 V input. This indicates that the Amplifier is very sensitive to audio signals while maintaining a low background noise. A high signal-to-noise ratio means that the Amplifier can produce clear and detailed sound that is free from interference and minimizes background noise. This feature is particularly important for audio enthusiasts seeking the best possible sound experience without compromise, especially when reproducing sensitive audio content.

What is the no-load current of the Hertz Cento CP 4.800?

The Hertz Cento CP 4.800 has a no-load current of 1.15 A. This value indicates how much current the Amplifier draws from the vehicle's network when idle, meaning without an audio signal. A low no-load current is crucial to avoid unnecessarily burdening the vehicle's Battery, especially in situations where the vehicle is stationary and the engine is off. The efficiency in idle state is an important factor for the overall efficiency of the Amplifier, particularly during longer breaks between active use.

What frequency bandwidth does the Cento CP 4.800 offer?

The frequency bandwidth of the Cento CP 4.800 ranges from 10 Hz to 47 kHz at -3 dB. This wide bandwidth ensures that the Amplifier can efficiently process both low-frequency signals, as required in subwoofers, and high-frequency sounds, which are important in tweeters. A comprehensive bandwidth ensures that the entire audio signature, from deep bass to high tones, is reproduced without significant distortion, resulting in a more natural, balanced sound profile.

How is the Cento CP 4.800 turned on and off?

The Cento CP 4.800 from Hertz features an intelligent control system with ART - Automatic Remote Turn-On/Off function. This function allows the Amplifier to automatically turn on or off when an audio signal is received from the SPK-IN that is at least 1.5 VDC. This not only saves energy but also prevents unwanted noise that can occur during manual on and off switching. This automation is convenient when you install the Amplifier in a system where multiple components need to interact with different requirements.

What are the dimensions of the Hertz Cento CP 4.800?

You can find the exact dimensions of the Hertz Cento CP 4.800 in the visual representation of the product description. The compact design of this Amplifier allows for easy installation in most vehicles, even those with limited space. Careful placement of the Amplifier is necessary to ensure optimal cooling and minimize interference from mechanical vibrations. It is particularly important not to mount the Amplifier in close proximity to heat-sensitive components and connection systems to ensure proper long-term functionality.
