Frequently Asked Questions about SR4,500

What output power does the Audison SR 4.500 Amplifier provide?

The Audison SR 4.500 delivers an impressive total power of 880 watts. In the 4-channel configuration, it reaches 130 watts per channel at 4 ohms and 220 watts at 2 ohms. In the 3-channel setting, it offers 120 watts for two channels at 4 ohms and 480 watts for one channel at 4 ohms, as well as 220 watts for two channels at 2 ohms and 440 watts for one channel at 4 ohms. Finally, in the 2-channel configuration, it achieves 450 watts per channel at 4 ohms. Whether you are looking for a precise sound experience or maximum power, the SR 4.500 meets all needs.

What are the dimensions of the Audison SR 4.500?

The Audison SR 4.500 impresses with its compact dimensions, which are specifically designed for flexible installation. The exact measurement is 264 mm x 234 mm x 155 mm. With a height of only 47.5 mm, the Amplifier can be installed almost anywhere in the vehicle without requiring many modifications. The rounded corners also help minimize space requirements. These compact dimensions allow for a clean and discreet installation, even in vehicles with limited space. This is a crucial advantage, especially in vehicles with tight space conditions.

Is the Audison SR 4.500 compatible with OEM radios?

Yes, the Audison SR 4.500 is compatible with Original Equipment Manufacturer (OEM) radios. Thanks to the symmetrical high-level inputs, the Amplifier can be directly connected to the OEM speaker output of the vehicle. This flexibility significantly facilitates integration into existing audio systems by allowing for seamless installation. Additionally, the SR 4.500 offers low-level RCA inputs for connection to aftermarket radios, making it versatile for nearly any audio configuration in the vehicle. These versatile input options simplify installation, regardless of the original vehicle model or audio system.

What filter options are available on the SR 4.500?

The Audison SR 4.500 is equipped with a fully integrated Crossover that offers a variety of filter options. The filters include high-pass filters from 50 Hz to 3.2 kHz at 12 dB/Octave and low-pass filters in the same frequency range and with the same steepness. These flexible filter options allow you to precisely adjust the sound reproduction to your specific listening needs and the acoustic conditions of the vehicle. The separate filters for the front and rear channels provide additional configuration options that are beneficial for both beginners and sound enthusiasts.

How does the automatic on and off function work on the Audison SR 4.500?

The Audison SR 4.500 is equipped with the ART function (Automatic Remote On/Off), which allows for automatic activation and deactivation of the Amplifier. This function uses the output signal from the speakers as a trigger to automatically turn the Amplifier on or off. This means that no separate remote control input is required, which simplifies installation and reduces wiring requirements. This function is particularly useful for simpler installations, allowing the Amplifier to be integrated into existing systems without additional control lines, thus enhancing user-friendliness.

What input sensitivities does the Audison SR 4.500 support?

The Audison SR 4.500 offers flexible input sensitivities to ensure optimal compatibility with various source devices. For the pre-in input, the adjustable sensitivity ranges from 0.2 to 5 VRMS, while the speaker input (Speaker-In) supports a range from 0.8 to 20 VRMS. These wide-ranging options allow you to use the Amplifier with both sensitive signals and more powerful sources. The precise adjustment of the input sensitivity ensures optimal amplification of audio signals and guarantees a high-quality sound experience, regardless of the type of source device used.

Can I adjust the subwoofer level on the Audison SR 4.500?

Yes, the Audison SR 4.500 allows for direct adjustment of the subwoofer level via the optional VCR-S1 remote control. With this remote, you can flexibly adjust the subwoofer level from -20 to +6 dB to suit your personal preferences and the conditions in the vehicle. This function is particularly useful for precisely tuning the bass to different music genres or the desired sound mood. A simple rotary knob on the remote allows for quick adjustments even while driving, without touching the main unit, enhancing comfort and user-friendliness.

What is the power consumption of the Audison SR 4.500?

The SR 4.500 from Audison is efficient in its energy consumption. In idle mode, the power consumption is only 1.7 Amperes, while in the off state it drops to an extremely low 0.09 mA. At maximum music output and a supply voltage of 14.4 VDC, the power consumption rises to about 40 Amperes. This efficiency is characteristic of Class D technology, which distinguishes the amplifier. This means that the amplifier is optimal for use in vehicles with limited energy potential, without placing excessively high demands on the vehicle's electrical system, thus preserving the lifespan of the car battery.

What safety features does the Audison SR 4.500 offer?

The Audison SR 4.500 is equipped with several integrated safety features to ensure reliable operation. It has a powerful heat sink that eliminates the need for an internal fan. This not only reduces operational noise but also minimizes the risk of thermal failure. Additionally, the energy-saving ART function allows for safe remote control of the on/off function. The dual 25-A fuse provides extra protection against overvoltage and short circuits. Thanks to these safety features, the SR 4.500 is well-suited for both daily drives and high-performance music sessions.

How is the installation of the Audison SR 4.500 in the car?

The installation of the Audison SR 4.500 is quite simple due to its thoughtful design. Thanks to its compact dimensions and sleek design with rounded edges, the amplifier can be easily integrated into almost any vehicle. The various input options, including high-level inputs, simplify the connection with existing audio systems. Furthermore, the amplifier is equipped with an integrated Crossover, which makes additional installation steps unnecessary. Pay attention to the dimensions and ensure adequate ventilation to guarantee optimal performance of the heat sink. By strictly following these steps, the installation is also manageable for less experienced installers.
