The Redline SA300.4 from DD Audio is a 4-channel amplifier with various power modes. At an impedance of 4 ohms, it delivers a continuous power of 4 x 65 watts RMS or 2 x 120 watts in bridged mode. At 2 ohms, the amplifier reaches 4 x 75 watts RMS. The dynamic power is 600 watts. Notably, the operating voltage range is from 10 to 16 volts, allowing use in different vehicle configurations. The amplifier has a maximum current draw of 30 amperes, which is remarkable in terms of efficiency considering its compact size.

How compatible is the Redline SA300.4 with various speaker systems?

The 4-channel amplifier Redline SA300.4 is specifically designed for DD coaxial speakers and components of the REDLINE series. It features variable 12dB crossovers that allow for more precise tuning of sound characteristics. With its RCA and high-level inputs, it can be easily integrated into existing systems, regardless of whether they use older or newer audio sources. This versatility allows for easy connection to various types of speakers, including the option to bridge the rear channels to operate an additional Subwoofer.

What are the main features of the Class-D topology of the Redline SA300.4?

The Class-D topology of the Redline SA300.4 amplifier is particularly noteworthy as it ensures high efficiency and low heat generation. This technology allows for a more compact design, saving both space and energy in everyday use. The efficient conversion of energy into audio power minimizes losses and maximizes operating time, especially under higher loads. Furthermore, the Class-D topology helps improve sound quality by reducing distortion and providing a more stable frequency response, particularly at high volumes.

What inputs and outputs does the Redline SA300.4 Amplifier offer?

The Redline SA300.4 Amplifier is equipped with various inputs and outputs that allow for flexible integration into different systems. This includes RCA inputs with a sensitivity of 6 to 2.5V as well as high-level inputs that can receive voltages from 20 to 1.1V. This versatility allows for use with both old and modern audio systems. Additionally, it features screw terminals for secure power connections and speaker connections, ensuring a reliable connection and thus stable performance.

What crossover options does the Redline SA300.4 offer?

The Redline SA300.4 Amplifier is equipped with variable 12dB crossovers that allow for flexible settings for optimal sound. Its low-pass and high-pass filters can be configured in the range of 35 to 250 Hz, allowing users to precisely adjust the frequency settings to specific speaker setups. This adaptability ensures that the amplifier is capable of delivering tailored sound performance for different music genres and listening preferences, which is advantageous when installed in advanced audio systems.

How can the Redline SA300.4 be installed in a car?

When installing the Redline SA300.4 Amplifier in a vehicle, its compact dimensions of 180 x 96 x 43 mm are a significant advantage, as they allow for flexible placement. The installation should take place in a well-ventilated area to ensure optimal heat dissipation. Note the required power cable thickness of 25 mm² and a speaker cable thickness of 4 mm² to achieve maximum performance. Screw terminals ensure secure connections, but solid grounding and correct wiring must be observed to minimize interference in the audio system.

What is the damping factor and how does it affect the Redline SA300.4?

The damping factor of the Redline SA300.4 Amplifier is over 70, a technical value that describes the amplifier's ability to control the speaker output. A higher damping factor generally means better control of speaker movement, leading to clean bass and lower distortion. In an audio system, especially at lower impedances, this is critical for optimizing the performance and sound quality of the entire system. The damping factor significantly contributes to precise sound reproduction.

What is the distortion level of the Redline SA300.4?

The Total Harmonic Distortion (THD) of the Redline SA300.4 Amplifier is below 0.1%, indicating very low distortion. This specific specification is crucial for the sound that the amplifier can deliver, as a low THD value means that the audio signals are reproduced almost faithfully. Especially in more complex audio systems, where precision and clarity are essential, this low distortion level ensures that the music sounds vibrant and clear, a quality that is particularly valued in audio components of this class.

What frequency response does the Redline SA300.4 support?

The Redline SA300.4 Amplifier supports a frequency response of 10 Hz to 30 kHz, allowing it to process a wide range of audio frequencies. This is crucial for reproducing both deep bass and high frequencies, ensuring balanced sound quality. This wide frequency response ensures that the amplifier accurately reproduces all audio content, from the lowest to the highest tones, making it ideal for use in high-quality audio systems that need to cover a broad sonic range.

What safety features does the Redline SA300.4 Amplifier have?

The Redline SA300.4 is characterized by its safe and reliable construction, highlighted by the use of screw terminals for power and speaker connections. These terminals ensure a secure connection and minimize the risk of loose or insecure connections that could lead to power outages or performance losses. Due to its Class-D topology, the amplifier generates less heat, reducing thermal stress and increasing long-term reliability. These features make it a dependable choice in any audio setup.

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.
