Frequently Asked Questions about Cento CP 1,700


What is the output power of the Hertz Cento CP 1.700 Amplifier?

The Hertz Cento CP 1.700 Amplifier delivers an output power of 700 Watts at 2 Ohms. The output power at 4 Ohms is 400 Watts x 1. These power ratings refer to the RMS power at 1% THD. The amplifier is a 1-Channel Amplifier of Class D, which allows for efficient energy transfer and low heat generation. With a power supply voltage of 11 to 15 VDC (with a Fuse of 2 x 25 A), there is sufficient power available for high-dynamic music passages. The amplifier is designed for demanding applications where rich deep bass and clear midrange are crucial. The high efficiency of 89% also contributes to this.

What operating and supply voltages does the Cento CP 1.700 support?

The Hertz Cento CP 1.700 can operate at a nominal power supply voltage of 11 - 15 VDC. However, the operating voltage of the power supply can vary in a range from 9 to 18 VDC. This flexibility allows the amplifier to be used in a variety of vehicles and with different power sources. The idle current of the device is 1.10 A, which minimizes power consumption when the amplifier is not in use. At a minimum load impedance, the maximum music power consumption is 33 A to deliver maximum power. These specifications make the amplifier robust and versatile.

What frequency ranges does the Hertz Cento CP 1.700 cover?

The Hertz Cento CP 1.700 Amplifier offers a bandwidth at -3 dB from 10 Hz to 500 Hz. This allows for a wide frequency range covering deep bass frequencies to high midrange frequencies. The crossovers are adjustable, so you can set the perfect transition between your speakers and subwoofers. Additionally, there are Pre-Out high-pass filters that filter frequencies in the range of 50 - 250 Hz at 12 dB/Octave. The sub-channel features a low-pass filter that can be turned off or set to 50 - 250 Hz at 24 dB/Octave. This variety of filter options provides optimized audio adjustment for different music genres.

What is the distortion and damping factor of the Cento CP 1.700?

The distortion of the Hertz Cento CP 1.700 at 100 Hz and 70% of the nominal power is a pleasing 0.01%. This very low distortion ensures high sound fidelity and clarity in audio signal output. The damping factor at 1 kHz and 1 watt is 350, which is significant for controlling speaker movements and allows for precise bass reproduction. These specifications guarantee that the amplifier is not only powerful but also of high audio quality. Especially at higher volumes, the Cento CP 1.700 offers impressive audio detail sharpness, which is crucial for music lovers.

What is the signal-to-noise ratio of the Hertz Cento CP 1.700?

The signal-to-noise ratio (SNR) of the Hertz Cento CP 1.700 is 113 dBA, A-weighted at a 1 V input. This high SNR means that the played audio is pleasantly clear, with minimal background noise. This is particularly important during quiet music sessions, where the details and nuances of the music come to the forefront. With an input sensitivity Pre-In of 0.32 to 8 VRMS, the amplifier offers flexibility to accommodate various sources with different volume levels. Overall, the Cento CP 1.700 is an excellent choice for audio systems that demand sound fidelity and low noise levels.

What type of input settings does the Cento CP 1.700 support?

The Hertz Cento CP 1.700 offers both Pre-In and Speaker-In inputs. The Pre-In sensitivity ranges from 0.32 to 8 VRMS, while the speaker input sensitivity can vary between 1.6 and 40 VRMS. These dual input options allow for flexible integration into various audio systems and enable access to source signals with different voltage levels, making the amplifier highly compatible with different audio sources. These input options provide extensive compatibility with nearly any signal source used in modern vehicles, giving you more freedom in designing and customizing your audio system.

How does the automatic remote control of the Hertz Cento CP 1.700 work?

The Hertz Cento CP 1.700 features the ART function, an automatic remote control for turning SPK-IN on and off, specifically designed for BTL radios. This function operates at a voltage of 1.5 VDC. It allows the amplifier to automatically turn on when a signal is detected and turn off when no signal is present. This is ideal for users who want a convenient and energy-efficient solution to automatically control their amplifier. The remote control input itself is designed to operate with a voltage between 4 to 17 VDC at 1 mA, ensuring safe and reliable control.

How does the bass boost affect the sound of the Cento CP 1.700?

The Hertz Cento CP 1.700 offers an optional bass boost at 50 Hz, adjustable from 0 to 9 dB. This adjustment allows for enhancing the bass range of the audio signal to achieve deeper and more powerful bass reproduction, which is particularly beneficial for music with punchy bass lines. The sub remote control for volume adjustment also provides versatile customization in the range of -20 to 6 dB, especially with the rear channel activated with LPF. This precise adjustment of the bass boost allows you to tailor the audio experience to your preferences for different music genres and acoustic scenarios.

What are the dimensions of the Hertz Cento CP 1.700?

The exact dimensions of the Hertz Cento CP 1.700 are not directly evident from the provided product information; however, when integrating it into a vehicle, it is important to consider both placement and airflow to avoid overheating. Therefore, it is advisable to carefully measure the available space in the vehicle during installation and ensure that the amplifier is not installed in a space that is too cramped, which could impair cooling. Proper installation ideally positions the amplifier in a location with sufficient airspace for heat dissipation, such as in the trunk or under a seat.

How do you install the Cento CP 1.700 with regard to crossovers and wiring?

When installing the Hertz Cento CP 1.700, it is crucial to correctly configure the adjustable crossovers. The high-pass filter for Pre-Out can be activated between 50 - 250 Hz at 12 dB/octave, and the sub-channel low-pass between 50 - 250 Hz at 24 dB/octave. It should be ensured that the connecting cables are properly connected and that the cable quality meets audio demands to avoid signal loss. Attention should also be paid to the correct wiring of the remote input voltage and the proper setting of the input sensitivity to ensure optimal performance. It is important to consider the vehicle's construction for cable routing.
