Frequently Asked Questions about RC70C4

What performance specifications does the Gladen RC 70C4 4-Channel Amplifier offer?

The Gladen RC 70C4 4-Channel Amplifier provides an exceptional RMS power of 4 x 68 watts at 4 ohms. Additionally, it can deliver 2 x 210 watts in bridged mode at the same 4 ohms. This demonstrates its remarkable ability to provide excellent audio quality in both standard and bridged configurations. The total harmonic distortion is very low at 0.5% at half maximum load, ensuring clear and precise audio playback. Particularly impressive is its signal-to-noise ratio of 95 dB, which minimizes background noise and allows for a purer listening experience.

How does the High-Level Auto Sense technology work in the RC 70C4?

The High-Level Auto Sense technology of the Gladen RC 70C4 automatically detects input signals to turn on the amplifier without the need for an additional remote signal. This greatly simplifies installation, as it is no longer necessary to run separate control wires. This feature is ideal for use in modern vehicles, where traditional connection options are often unavailable. The technology utilizes an input sensitivity of 0.2 - 10 Vrms to ensure that the amplifier is reliably activated across different sources.

What protection mechanisms are integrated into the Gladen RC 70C4?

The Gladen RC 70C4 is equipped with a thermal protection function that safeguards the amplifier at temperatures above 80 °C. This mechanism prevents overheating and thus extends the lifespan of the device. In cases of overload or extreme operating conditions, the protection activates to preserve internal components from damage. Together with the Double Side PCB and SMD components, this protection ensures that the amplifier reliably and safely delivers its performance even under demanding conditions.

What role does the Double Side PCB play in the Gladen RC 70C4?

The double-sided PCB in the Gladen RC 70C4 ensures a higher component density, allows for a more compact design, and better heat distribution. This construction ensures that electrical connections are shorter and thus more efficient, leading to reduced signal loss. In conjunction with the SMD components, the reliability of the amplifier is further enhanced. This design is particularly advantageous if you value a clear sound image and a durable construction, as it makes the amplifier robust and powerful.

What is the bandwidth of the Gladen RC 70C4 specified?

The Gladen RC 70C4 offers a bandwidth of 20 - 20000 Hz with a tolerance of ±1 dB. This means that the amplifier is capable of reproducing the full audio frequency range with only minimal deviations in amplification. This leads to precise reproduction of music, from deep bass to clear highs. Especially for Hi-Fi enthusiasts who do not want to compromise on sound quality, the RC 70C4 offers impressive fidelity across the entire audible range.

How does the Gladen RC 70C4 affect the impedance of the speakers?

The Gladen RC 70C4 has a low input impedance of 5k Ω and a high input impedance of 50 Ω when the RC-HLT is used. This feature allows for efficient driving of various types of speakers and ensures optimal sound reproduction. Particularly when it comes to integration into existing systems or operation with special speakers, the amplifier offers flexibility through its impedance adaptability, which ensures stable and consistent performance.

What is the power consumption of the Gladen RC 70C4?

The power consumption of the Gladen RC 70C4 is 0.75 A at idle. In stereo operation at 4 ohms, a current consumption of 29 A is recorded. In bridged operation at 4 ohms, this rises to 47 A. When power is needed at 2 ohms, the consumption remains constant at 47 A as well. These data show that the RC 70C4 handles energy efficiently while still having the capability to deliver strong performance in various configurations, highlighting its suitability for flexible applications.

What advantages do SMD components offer in the Gladen RC 70C4?

SMD components in the Gladen RC 70C4 enable a more compact design and increase the reliability of the circuit. This technology reduces the risk of mechanical shocks or vibrations that can occur in vehicle environments. Additionally, SMD components contribute to improved heat distribution, which reduces the risk of overheating. By efficiently utilizing the circuit board area, more components can be accommodated in less space, enhancing the amplifier's performance without compromising on compactness.

How important is the weight of the Gladen RC 70C4 for its performance?

The Gladen RC 70C4 weighs only 2.2 kg, which is remarkably light for an amplifier with such power. This lightness offers advantages for integration into vehicles, as it allows for installation without significant additional strain on the vehicle. Despite its low weight, the amplifier delivers high performance and is robustly built. This is particularly beneficial for users who want a powerful sound system without having to compromise on portability or installation.

What are the dimensions of the Gladen RC 70C4 and how does that affect installation?

The Gladen RC 70C4 has compact dimensions of 283 mm in length, 150 mm in width, and 50 mm in height. These measurements allow for easy integration into most vehicles, as it can be placed in a small space without being in the way or requiring many adjustments. Due to its compact size, you can efficiently and space-savingly mount the amplifier even in limited installation space, making it particularly suitable for installations where the available space in the vehicle is tight.

Top für den Preis !!!

Hören sich gut an!!! hätte ich nicht gedacht in der Preisklasse, vor allem der Pegel hab sie mit paar Axton Hochtönern verbaut und einem Kicker sub im Kofferraum und paar Rainbow Endstufen sauberer lauter klang bin sehr zufrieden mit dem Produkt. Langzeit noch keine Erfahrung da erst zwei Wochen verbaut

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.
