Frequently Asked Questions about CO-650.1 D

What power does the CO-650.1 D Amplifier provide at different resistances?

The CO-650.1 D Amplifier from Audio System offers different power ratings depending on the resistance. At 4 Ohms, it delivers 1x 400 WRMS, which is sufficient for decent sound with a larger Subwoofer. At 2 Ohms, it reaches 1x 650 WRMS, which is ideal for powerful car systems that prefer intense bass. The high performance of the Audio Amplifier ensures that a stable and clear sound quality is maintained even at low resistances, with the efficiency of the CO-650.1 D particularly highlighted by Class-D technology.

How efficient is the Audio System CO-650.1 D Amplifier?

The CO-650.1 D Amplifier from Audio System operates with Class-D amplifier technology, which ensures high efficiency. The efficiency of up to 84% means that the amplifier converts more electrical power into acoustic power while losing less energy as heat. This provides maximum sound output with minimal energy consumption, which is especially advantageous when used in a car. Particularly for operation in the trunk, this technology offers sustainable sound enhancement, as less heat is generated, thereby supporting the longevity of the device.

What filter functions does the CO-650.1 D offer?

The CO-650.1 D Amplifier is equipped with several precise filter functions specifically designed for discerning audiophiles. The Low Pass Filter allows for selecting the frequency ranges that are optimal for a Subwoofer by filtering out higher frequencies. The Subsonic filter is designed to eliminate unwanted low frequencies that are not audibly relevant, maximizing the amplifier's performance and protecting the Subwoofer. Both filters work together to guarantee the clearest and most powerful bass reproduction, which can be tailored to the user's preferences.

What does the continuously adjustable 0-180° phase shift on the CO-650.1 D mean?

The continuously adjustable 0-180° phase shift of the CO-650.1 D allows for precise adjustment of the audio output phase. This feature is particularly useful when amplifiers and speakers are not installed at the same distance from the listener or when multiple Subwoofers are used. By adjusting the phase, interference in the sound image can be minimized, leading to clearer and more precise bass reproduction. The result is an optimally synchronized sound that significantly enhances the audio experience in the car and can be individually tailored to any acoustic environment.

What benefit does the RTC Bass Remote Control provide with this amplifier?

The RTC Bass Remote Control for the CO-650.1 D amplifier offers the convenience of adjusting the system's bass level directly from the driver's seat. This is especially practical when listening to different music genres or when the bass level needs to be adjusted during live operation without manually touching the amplifier. This remote control allows for lightning-fast changes in bass intensity, ensuring optimal control and a customized listening experience. Those with varying sound preferences particularly benefit from the flexibility and user-friendliness of this feature.

What are the dimensions of the CO-650.1 D and how does that affect installation in the car?

The CO-650.1 D has compact dimensions of 230 x 47 x 171 mm, making it ideal for installation in the car, especially in the trunk or under a seat. Its space-saving design facilitates installation, as the amplifier can also be fitted in vehicles with limited space. When installing, care should be taken to ensure adequate ventilation for heat dissipation to maintain optimal performance and longevity of the device. The installation is flexible, as it is not restricted by oversized dimensions, making it easier to adapt to different vehicle models.

What features does the RCA high-level input of the CO-650.1 D offer?

The RCA high-level input of the CO-650.1 D Amplifier allows for direct connection of the device using speaker wires from the car radio, even if it does not have low-level outputs. This is particularly advantageous for cars without dedicated preamp outputs, as no additional adapters are needed to connect the amplifier. The automatic turn-on mechanism makes usage easier by activating the amplifier without manual switching as soon as a signal is detected. This functionality makes the CO-650.1 D versatile and compatible with a variety of in-vehicle audio systems.

How do I adjust the EQ at 45Hz?

The CO-650.1 D Amplifier features an EQ that is specifically adjustable to 45Hz to enhance the bass range. If you want to adjust the bass level, you can do so within a range of 0 to 6 dB, depending on your personal preference for bass intensity. This feature is useful if you prefer specific audio signatures that require more depth or to make a direct adjustment to the acoustic conditions of your vehicle. The right setting can significantly improve sound quality and be tailored to your individual listening habits.

What should be considered when combining the CO-650.1 D with Subwoofers?

When combining the CO-650.1 D with Subwoofers, it is important to keep an eye on the impedance of the Subwoofer to utilize its full performance. If the Subwoofer is in the 4 or 2-ohm range, the amplifier provides the corresponding outputs of 400 WRMS and 650 WRMS, respectively. The impedance of the Subwoofer must be compatible with the output impedance of the amplifier to avoid overload or damage. Additionally, the positioning of the Subwoofer in the vehicle should be optimally chosen to ensure even bass distribution within the vehicle's interior.

How is the CO-650.1 D Amplifier installed in the vehicle?

Installing the CO-650.1 D Amplifier in the vehicle requires careful consideration of placement and wiring. It is compact enough to be mounted in the trunk or under the seat, while ensuring adequate ventilation. The connection is made via the RCA high-level input or classic preamp outputs, depending on your car radio. When wiring, high-quality cables and correct polarity should be used to minimize signal loss or interference. The continuously adjustable phase shift should then be adjusted according to the Subwoofer position for ideal sound tuning.

Versterker was goed verpakt, En heb dit beest heeft zo veel power!

Versterker was goed verpakt, En heb dit beest gelijk getest op volume en klinkt geweldig op mijn subwoofers, Het geluid vervormd niet zelfs op vol volume klinken de bas tonen zuiver, Ben vooral blij dat ik deze versterker gekocht heb. Ik geniet van elke seconde in mijn auto,Ik kon het merk niet van de versterker [gs-audio] maar het is top merk en het is met de hand gemaakt en komt uit Italy is echt goed gemaakt alleen mijn auto heeft het zwaar te verduren alles beweegt, Dus top aankoop gedaan.
