Purchase decision and technical highlights of the DD Audio Redline SA300.4 amplifier

The DD Audio Redline SA300.4 is your ideal companion if you're looking for a powerful 4-channel amplifier. With its advanced Class-D topology, this amplifier offers an effective solution for use with DD coaxial speakers and REDLINE series components. The ability to bridge the rear channels allows you to easily connect a subwoofer, adding more depth to your sound. The Masori Lowest Price Guarantee ensures that you always get this amplifier at the best price—a key advantage when buying online. The SA300.4 is specifically engineered to maximize efficiency and sound quality, setting it apart from conventional models and making it suitable for a wide variety of applications.

Performance characteristics of the DD Audio amplifiers when used with 4 Ohm speakers: 4 x 65 Watt RMS

The DD Audio Redline SA300.4 delivers an impressive 4 x 65 watts RMS continuous power at 4 ohms. This power is optimal for amplifying DD coaxial speakers and REDLINE components. This RMS power ensures consistent and clean audio output from the speakers, resulting in rich lows and clear mids and highs. Compared to typical amplifiers in the car hi-fi market, which often offer an RMS power output between 40 and 60 watts, this amplifier delivers an excellent level of additional power for higher-end audio systems. A power output higher or lower than 65 watts could result in either excessive wear or inadequate sound quality.

Amplifier power below 2 ohms: 4 x 75 watts RMS for more intense audio reproduction

The ability to deliver 4 x 75 watts RMS into 2 ohms makes the DD Audio SA300.4 a versatile choice. This increased wattage gives speakers operating at lower impedances more power, enabling powerful and precise audio reproduction even at high sound pressure levels. In the car hi-fi world, such performance levels often offer the opportunity to tailor the sound character to one's own taste.

Unique frequency response from 10 Hz to 30 kHz for audiophile experiences

With a frequency response ranging from a low 10 Hz to a crystal-clear 30 kHz, the DD Audio Redline SA300.4 covers a wide spectrum of sound frequencies. This range offers both deep bass and high tones that might be lost in other amplifiers. This frequency response ensures that every note is heard exactly as intended. The SA300.4 stands out noticeably from amplifiers that often only extend to 20 kHz, offering detailed sound fidelity that provides the listener with more depth.

Efficient Class-D topology for maximum sound quality in a small form factor

The Class-D topology of the DD Audio Redline SA300.4 ensures high energy efficiency without compromising sound quality. This technology reduces heat loss and enables a compact design. Compared to more traditional Class-AB amplifiers, which require more power and space, the SA300.4 offers a modern solution, especially in vehicles with limited space.

Variable 12dB crossovers for precise sound

One of the outstanding features of the DD Audio Redline SA300.4 is its 12 dB variable crossover. This feature allows you to precisely adjust the crossover frequencies to the speakers and subwoofer used. This allows you to precisely determine which speaker outputs which frequencies, resulting in an optimized and coherent soundscape. Compared to fixed crossovers that don't allow for adjustments, the SA300.4 offers much more flexibility in system configuration.

Connection options via RCA and line-level inputs

The SA300.4 is equipped with RCA and line-level inputs, allowing for quick and easy integration into existing audio systems. This flexibility supports use in both simple and sophisticated setups. This variety of input options distinguishes the amplifier from many others that offer only one type of input, thus severely limiting the possible applications.

Secure connection thanks to robust screw terminals

The use of screw terminals on the SA300.4 ensures secure and stress-free connections for power and speaker cables. This connection method minimizes contact problems and resistance, resulting in a stable power supply and consistent sound transmission. In the car hi-fi world, screw terminals are known for their superior connections compared to spring terminals, which often suffer from loose connections.

Bridging option for subwoofer integration

The DD Audio Redline SA300.4 offers the ability to bridge the rear channels. This feature gives you the flexibility to integrate a subwoofer into your system without the need for a separate amplifier. This type of customization is particularly well-suited for users who want to add bass to their car information system. Unlike many other amplifiers that don't offer bridge options, the SA300.4 is an excellent choice for extended in-vehicle use.

RMS continuous power in bridged mode: Maximum efficiency with 2 x 120 watts at 4 ohms

When operated in bridged mode, the DD Audio Redline SA300.4 delivers an outstanding continuous power output of 2 x 120 watts at 4 ohms. This configuration is ideal for high-performance audio systems requiring additional amplification. This ability to produce higher power than typical of conventional amplifiers opens up additional options for high-quality subwoofer integration without the need for additional components.

Maximum current consumption of 30 amps for stable performance without overvoltage

The DD Audio Redline SA300.4's current consumption is a maximum of 30 amps, ensuring stable performance without the risk of overheating or voltage drops. This is especially important for mobile audio applications, as larger amplifiers draw far more than the typical 20 amps required by less stability-conscious models. This ensures that the amplifier operates smoothly at all volume levels, which is crucial for a long service life.

Input sensitivity: Precise adjustment of RCA and high-level inputs

With an RCA input voltage sensitivity of 6 – 2.5V and a high-level input voltage sensitivity of 20 – 1.1V, the DD Audio Redline SA300.4 allows for precise adaptation to various audio sources. This high adaptability is crucial to ensure compatibility diversity and to ensure that signal strength does not compromise the desired sound quality.

Dimensions and space requirements: Clever design for flexible installation

Measuring 180 mm x 96 mm x 43 mm, the amplifier is remarkably compact yet offers all the powerful features you'd expect from a high-quality amplifier. This size facilitates installation in a wide variety of vehicles, especially those where space is limited. Such integration into a vehicle's interior is optimized by the efficient use of interior space.

Damping factor and THD for excellent audio resolution

The damping factor of over 70 and the THD of less than 0.1% are indicators of the exceptional quality of the DD Audio Redline SA300.4. A high damping factor ensures a tight and precise bass response, while a low THD keeps distortion to a minimum, resulting in a pure and unadulterated sound. The SA300.4 surpasses many other models on the market, which often only offer comparable sound above these limits.
