The ESX Signum SXE250.4 offers an impressive maximum output power of 2000 watts, which can be utilized in various ways. In single mode, the amplifier delivers a power of 4 x 300 watts at an impedance of 4 ohms or 4 x 500 watts at 2 ohms. This allows for versatile application and adaptability to different speaker configurations. When bridged, the amplifier reaches up to 2 x 1000 watts at 4 ohms. The high power is ideal for users looking for a powerful sound experience in their vehicle. Additionally, the amplifier provides 4 x 150 watts RMS at 4 ohms or 4 x 250 watts RMS at 2 ohms, ensuring consistent power even over longer periods.
The ESX Signum SXE250.4 impresses with massive connection terminals that guarantee secure and loss-free transmission of audio signals. Furthermore, it features high-level inputs with an automatic power-on function, allowing for easy setup. Particularly noteworthy is the integrated 'Error Protection System', which protects the amplifier from overheating, short circuits, and overload, significantly increasing longevity and reliability. These features make the amplifier particularly interesting for users who value maximum safety and convincing performance in their vehicle. The aluminum heat sink with acrylic glass inserts also ensures effective heat dissipation.
The ESX Signum SXE250.4 is versatile in sound control, as it is equipped with a high-pass filter (HPF) and a low-pass filter (LPF). The HPF covers frequencies from 10 to 250 Hz, while the LPF processes frequencies from 50 to 250 Hz. Together, these filters allow for precise tuning and adjustment of the sound to individual preferences and speaker requirements. Additionally, the amplifier offers a variable bass boost of 0 to 12 dB and a bandpass mode to finely tune the sound in any vehicle. These options ensure that users who require a wide range of audio fine-tuning are optimally served.
The ESX Signum SXE250.4 measures 220 x 53 x 460 mm and offers a compact design despite its power. These dimensions simplify installation, as the amplifier can easily fit under seats or in the trunks of vehicles of various sizes. It is important during installation to ensure that the amplifier is cooled by adequate air circulation to avoid overheating, especially during prolonged use. Additionally, the amplifier must be securely mounted on a stable surface to prevent vibrations and movements while driving, which supports the protection of the internal electronics and optimizes the noise environment in the car.
The aluminum heat sink of the ESX Signum SXE250.4 is essential for heat dissipation and ensures that the amplifier maintains its performance even under more extreme conditions. Aluminum as a material is ideal due to its excellent thermal conductivity, as it efficiently dissipates the heat generated during intense use. This not only protects the internal components from overheating but also significantly extends the lifespan of the device. The integrated acrylic glass inserts and the diamond-cut logo not only contribute to the aesthetics but are also functionally integrated into the heat sink design to achieve maximum efficiency. These features are particularly beneficial for users who place a high value on durability while maintaining consistent sound quality.
The NE5532 operational amplifiers integrated in the ESX Signum SXE250.4 are crucial for the sound quality and clarity that the amplifier delivers. These amplifiers are known for providing excellent resolution across a wide frequency range and minimizing distortion. This ensures that music lovers who prefer clear sound and fidelity get their money's worth. The NE5532 operational amplifiers are also famous for their reliability and low distortion rate, which is particularly important at high volumes to ensure a clean audio signal without sound loss. This makes the Signum SXE250.4 an excellent amplifier for discerning audio enthusiasts.
The automatic power-on function of the ESX Signum SXE250.4 via the high-level inputs is particularly practical and user-friendly. This function allows the amplifier to turn on automatically when an audio signal is detected. This eliminates the need for additional control lines or switches, simplifying installation and making everyday use more comfortable. This is especially useful for users who want to use the system regularly in different vehicles or environments, as it saves time and simplifies the overall installation process. This automatic solution also prevents the classic 'pop' sound when turning on, ensuring a seamless transition to the music.
The ESX Signum SXE250.4 features a triple protection circuit that safeguards the amplifier against overheating, short circuits, and overload. This function is essential to preserve the amplifier from damage and promote its longevity. The protection mechanism automatically intervenes when one of the mentioned hazards is detected and temporarily shuts down the device to protect the internal components from damage. Especially in vehicles where extreme temperatures can occur and where speaker configurations may sometimes be inconsistent, this triple protection ensures that the amplifier operates reliably and safely even under intense use. This is aimed at technology enthusiasts who value stable and secure operation.
The robust base plate of the ESX Signum SXE250.4 with mounting brackets allows for flexible placement in the vehicle. Due to its size, it is ideally suited to be installed under seats or in the trunk. It is important to ensure that there is sufficient space for air circulation to allow the aluminum heat sink to work effectively. Accurate placement reduces possible vibrations and associated noise development, contributing to a better listening experience. Additionally, care should be taken to keep the connections for high-level inputs, power supply, and speaker cables easily accessible to facilitate adjustments if necessary.
The ESX Signum SXE250.4 uses Class A/B amplifier technology, which is known for its excellent sound quality and efficiency. Compared to Class D amplifiers, which are designed for digital applications and higher efficiency, Class A/B technology offers a warmer and more natural sound with minimal distortion. This technique combines the advantages of Class A, which provides a continuous voltage, with those of Class B, which only amplifies when a signal is present, resulting in an effective balance between sound purity and energy efficiency. These characteristics make the amplifier particularly interesting for audiophiles who value a pleasant and detailed sound in the car, even at high volumes.
