Frequently Asked Questions about SR 1,500

What power does the Audison SR 1.500 Amplifier offer?

The Audison SR 1.500 is a powerful 1-channel amplifier with an impressive RMS power of 1000 W. The output power varies depending on the load: at 4Ω it delivers 500 W, at 2Ω 800 W, and at 1Ω the full 1000 W. With its 1-ohm stability and D-Class technology, it is suitable for intense and high-quality sound experiences. The built-in crossover optimizes sound quality and expands its applications. Its S/N ratio of 100 dBA ensures clear sound reproduction, ideal for demanding audio installations. These performance features make it a versatile companion for audio enthusiasts.

What are the dimensions of the Audison SR 1.500 and how does this affect installation?

The Audison SR 1.500 Amplifier measures 264 mm in length (A), 234 mm in width (B), 155 mm in depth (C), 135 mm in height (D), and has a thickness of 47.5 mm (E). These compact dimensions facilitate installation in vehicles with limited space. The rounded corners of the design further minimize space requirements and make integration into existing audio setups easier. Despite its small size, the amplifier impresses with its performance. Its dimensions allow for flexible installation options, ideal for cars with limited trunk or interior space.

How does the crossover work in the Audison SR 1.500?

The Audison SR 1.500 Amplifier features a fully integrated crossover that stands out for its adaptability and precision. It offers a full LP filter in the frequency range of 50 - 250 Hz at 24 dB/Oct, allowing for efficient separation of subwoofer and main speaker signals. Additionally, there are PRE OUT outputs with a hi-pass filter for the same frequency range. The built-in subsonic filter operates at 25 Hz with 24 dB/Oct to eliminate unwanted low-frequency disturbances. This configuration enhances sound and reduces distortion, ideal for audiophile users.

What special technical features set the Audison SR 1.500 apart from other amplifiers?

The Audison SR 1.500 Mono Amplifier impresses with a variety of technical features: The Universal Speakers Simulator (USS) function allows integration with different speaker systems. The symmetrical high-level inputs, RCA low-level connections, and remote in/out socket provide flexible connection options and control features. The ART function (Automatic Remote On/Off) saves energy and simplifies operation. Its ability to operate stably at low impedances of just 1Ω, combined with an excellent damping factor of >300, makes it suitable for any complex audio installation. All these factors shape it into a powerful powerhouse.

What inputs does the Audison SR 1.500 Amplifier offer?

The Audison SR 1.500 Amplifier is equipped with versatile input options that make it flexible and adaptable for different audio setups. It features pre-in and speaker-in inputs to accommodate various systems. The low-level RCA inputs are specifically designed for aftermarket radios, while the high-level inputs are suitable for connecting to OEM speaker outputs. The symmetry of these inputs minimizes interference, while the input sensitivity is variably adjustable between pre-in (0.2 - 5 VRMS) and speaker-in (0.8 - 20 VRMS), supporting precise calibration of the audio signal.

How energy efficient is the Audison SR 1.500?

The Audison SR 1.500 is designed for high energy efficiency, which is reflected in its operating parameters. At a nominal supply voltage of 14.4 VDC, the current consumption at maximum power and 2Ω load is about 40 A. The idle current is only 0.8 A, while the power consumption in the off state is extremely low at 0.02 mA. The supply voltage is flexibly adjustable between 11 and 15 VDC. Thanks to the ART function (Automatic Remote Turn-on), energy consumption is efficiently managed. These features reduce the overall energy demand, make the amplifier resource-efficient, and extend the battery life.

What amplifier class does the Audison SR 1.500 use and what are its advantages?

The Audison SR 1.500 uses D-Class amplifier technology, known for its high energy efficiency and low heat loss. D-Class amplifiers are particularly advantageous for installation in vehicles, as they require less space and minimize heat generation. This class allows the amplifier to operate efficiently even under high power demands. The resulting lower power consumption reduces the load on the vehicle's battery. D-Class amplifiers are ideal for high-quality, high-performance audio applications, as their efficiency maximizes audio performance without compromising sound quality.

How does the damping factor affect the performance of the Audison SR 1.500?

A high damping factor, as provided by the Audison SR 1.500 (over 300), improves the amplifier's control over the speaker cone movement. This leads to more precise bass reproduction and a cleaner sound image. The damping factor is crucial for audio quality, especially when using subwoofers or speakers with large cones. An amplifier with a high damping factor minimizes distortion and resonances within the speaker system. The Audison SR 1.500 effectively utilizes this feature to deliver outstanding sound fidelity, which is of great importance to the audiophile listener.

Can I use the Audison SR 1.500 with different car brands?

The Audison SR 1.500 amplifier is universally designed and compatible with many car brands due to its compact dimensions and versatile inputs. Its balanced high-level inputs allow for easy integration into existing OEM systems, while the low-level RCA inputs are particularly suitable for aftermarket radios. However, since installation with a power of 1000 W at 1Ω requires an adequate power supply, it should be ensured that the vehicle has a sufficiently strong alternator. Always check the existing electrical infrastructure of the vehicle to avoid compatibility issues.

What control options does the Audison SR 1.500 amplifier offer?

The Audison SR 1.500 offers several control options that allow for customized sound settings. An optional VCR-S1 remote control allows adjustment of the subwoofer level from -20 to +6 dB to tailor music playback to personal preferences. The Remote IN/OUT socket facilitates synchronization and control of multiple amplifiers within a system. Additionally, the ART function (Automatic Remote On/Off) provides convenience by automatically turning on the amplifier when an audio signal is detected. Together, these controls give users the freedom to optimize their audio experience individually.

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.
