Frequently Asked Questions about SR 4.300

What power does the Audison SR 4.300 Amplifier provide?

The Audison SR 4.300 is a 4-channel amplifier with a total RMS power of 520 W. At a supply voltage of 14.4 VDC and a distortion of 1% THD, it delivers 85 W per channel at 4 Ohms and 130 W per channel at 2 Ohms. In the 3-channel configuration, the power is 80 W for two channels at 4 Ohms plus 250 W for one channel also at 4 Ohms. The 2-channel configuration provides 250 W per channel at 4 Ohms. This flexibility in output power makes it a versatile amplifier for various audio systems.

How does Class D technology affect the sound quality of the Audison SR 4.300?

The Audison SR 4.300 uses the latest Class D technology, which allows for high efficiency in a compact design. This amplifier class is known for its outstanding performance, particularly in minimizing losses and increasing efficiency, resulting in lower heat generation. The sound quality remains top-notch thanks to a low distortion value of 0.03% THD at 70% of the rated power. This leads to clear and precise sound that meets the demands of audiophile users. Class D amplifiers are ideal for compact installations as they require less cooling.

What are the dimensions of the Audison SR 4.300 and how do they affect installation?

The Audison SR 4.300 features compact dimensions: it is 190 mm long, 160 mm wide, and has a depth of 47.5 mm. The relatively small size makes installation easier in vehicles with limited space. Thanks to these dimensions, the amplifier fits easily in most trunk areas or under the driver or passenger seats. Its low height plays a crucial role in discreet integration without major modifications to the vehicle. The installation location should be well-ventilated to avoid overheating and support the cooling system.

What filter options does the Audison SR 4.300 Amplifier offer?

The Audison SR 4.300 features flexible filter settings that allow for fine-tuning of the sound. Channel A offers an adjustable high-pass filter (50 - 3.2 kHz), while Channel B provides a low-pass filter function with the same frequency range. These filters operate with a slope of 12 dB/Octave, enabling precise adjustments to individual sound preferences or the specific requirements of the speaker system. Particularly advantageous is the ability to adapt the amplifier for both full-range applications and specific frequency bands. These versatile filter options are ideal for tuning projects.

What is the power consumption of the Audison SR 4.300 amplifier?

The SR 4.300 from Audison is designed for low power consumption. In idle mode, the power consumption is only 1.6 A, while in the off state it is a remarkable 0.03 mA. At maximum music power, the amplifier draws about 25 A, making it quite an efficient model. The supply voltage fluctuations from 11 to 15 VDC are handled effortlessly, ensuring consistent performance. This efficiency allows the amplifier to be effectively operated in small spaces without excessively burdening the vehicle battery, such as in vehicles with smaller battery capacities.

How is the connection of the Audison SR 4.300 to OEM sources made?

The Audison SR 4.300 supports easy connection to OEM sources through its universal speaker simulations and high-level input connection. These functionalities allow for seamless integration of the amplifier into existing audio systems without the need for specialized adapters. The nominal input sensitivity for pre-in signals ranges from 0.2 to 5 VRMS, while the sensitivity for speaker-in signals ranges from 0.8 to 20 VRMS. The electronic design ensures that the sound is transmitted uncompromisingly, regardless of the specific characteristics of the original vehicle audio source.

What is the damping factor of the Audison SR 4.300 and what does it mean?

The Audison SR 4.300 has a damping factor of 150, which is crucial for controlling the speaker through the amplifier. A high damping factor means better handling of the speaker diaphragm, leading to a more precise sound image. This is especially relevant at low frequencies, where control over diaphragm movement ensures clarity and clean bass reproduction. This technical aspect is important for users who place a high value on audio quality, as it improves the playback of music with deep, powerful bass and minimizes distortion.

Are there tips for installing the Audison SR 4.300 in the car?

When installing the Audison SR 4.300, there are some technical details to consider. The dimensions of 190 x 160 x 47.5 mm make it compact, ideal for placement under seats or in the trunk. It is important to mount it in a well-ventilated area to optimize heat dissipation. Use power cables that match the power consumption of up to 25 A at maximum music power, ideally with a 30A fuse. Be sure to connect the polarity correctly and check the vehicle's existing power supply voltage to ensure compatibility.

Why is the automatic on/off function of the SR 4.300 useful?

The Audison SR 4.300 features an automatic on and off function called ART (Automatic Remote Turn-On/Off). This function allows the amplifier to turn on automatically when it detects an audio signal and turn off again when the signal disappears. This reduces manual effort, as no separate remote switch is necessary, and prevents the amplifier from drawing unnecessary power from the vehicle's battery, which is particularly relevant when the car is parked for an extended period. Thus, the ART function contributes to energy efficiency and user-friendliness.

What input types does the Audison SR 4.300 offer?

The Audison SR 4.300 is equipped with both pre-in and speaker-in input types. The pre-in inputs support an input sensitivity of 0.2 to 5 VRMS, allowing integration with preamplifier outputs. The speaker-in connections accept an input voltage of 0.8 to 20 VRMS, enabling the amplifier to be connected directly to speaker wires. This versatility ensures that the amplifier is compatible with a variety of audio sources, allowing it to be used in different setups without major adjustments. Ideal for seamless integration into existing systems.
