Frequently Asked Questions about SXT900.4 (24V)

What power does the SXT900.4 (24V) provide at 4 Ohm and 2 Ohm?

The SXT900.4 (24V) Amplifier from ESX delivers an RMS power of 4 x 125 Watts at 4 Ohm and 4 x 225 Watts at 2 Ohm. This allows for flexible adaptation to different speaker systems. If you bridge the channels of the amplifier, you get a power output of 2 x 450 Watts RMS at 4 Ohm. This power makes the amplifier ideal for demanding audio applications where precise detail reproduction is desired. Thanks to Class D amplifier technology, energy consumption remains low, which in turn increases the efficiency of the system.

What frequency ranges do the high-pass and low-pass filters of the ESX SXT900.4 cover?

The high-pass and low-pass filters of the SXT900.4 (24V) from ESX are adjustable for both the front and rear channels in the frequency range of 50 Hz to 5000 Hz. These filter options allow for precise adjustment of the sound profile according to your specific sound requirements. Whether you prefer the highest precision in the highs or the deepest bass reproduction, the filters enable individual fine-tuning that is optimally matched to the speaker system. Note that correct filter settings are crucial to minimize distortion and ensure clear sound.

How efficient is the amplifier and what advantages does it bring?

The ESX SXT900.4 (24V) features an efficiency of up to 90%. This high efficiency results from the use of Class D amplifier technology, which minimizes the conversion of power into heat, improves battery usage, and shortens charging times. The amplifier-driven aluminum die-cast heat sink also contributes to efficient heat management by quickly dissipating the heat generated during intense use. This is particularly beneficial when you run long audio streams, as the amplifier guarantees stable performance even under continuous load.

What adjustments are possible with the input selector switch?

The ESX SXT900.4 (24V) is equipped with a 2CH/4CH input selector that allows you to adjust the number of input channels based on your setup. You can operate the amplifier with either two or four channels, making it particularly flexible for various configurations. This option is significant if you want to expand or optimize existing systems without having to change the entire audio wiring. The ability to switch supports easy integration into your existing audio system.

How does the automatic power-on function of the SXT900.4 (24V) work?

The ESX SXT900.4 (24V) features an automatic power-on function that activates the amplifier as soon as a music signal is present. This means that the amplifier does not need to be turned on manually, significantly enhancing convenience and simplifying operation. This automatic function also conserves the battery, as the amplifier is only active when needed. The technology detects voltage changes and responds immediately, allowing seamless integration with various audio systems. This is a practical option, especially in automated vehicle environments.

What are the dimensions of the amplifier and how does that affect installation?

With compact dimensions of 140 x 44 x 225 mm, the ESX SXT900.4 (24V) is designed to save space. This is a crucial advantage if you want to avoid space issues in your vehicle. The small form factor makes installation easier in tighter areas without the need for extensive modifications to the existing infrastructure. This compact design allows the amplifier to be integrated almost invisibly, which additionally supports the visual aesthetics of your vehicle without compromising on performance.

What features does the Bass Boost in the SXT900.4 (24V) enhance?

The integrated Bass Boost of the ESX SXT900.4 (24V) allows for an amplification of lower frequencies in the range of 0 to 12 dB in the rear channel. This feature is particularly useful when you want to achieve powerful bass reproduction in your audio system. By boosting low frequencies, you can better tailor the sound character to your musical preferences without affecting the other frequency ranges. Especially if you enjoy listening to music loudly and want to feel the bass intensely, this feature provides significant added value.

How does the aluminum die-cast heat sink contribute to performance?

The aluminum die-cast heat sink in the ESX SXT900.4 (24V) offers optimal cooling properties. The aluminum design ensures effective heat dissipation, which is crucial during intense use of the amplifier. Good cooling prevents overheating damage and improves the lifespan of the device. With even heat distribution, performance remains consistent even under demanding conditions. If you operate your amplifier for extended periods, the reliable cooling provided by the aluminum die-cast heat sink is a significant advantage.

What types of inputs does the SXT900.4 (24V) amplifier offer and what are their benefits?

The ESX SXT900.4 (24V) is equipped with RCA and high-level inputs that are secured with an Error Protection System (EPS®). The RCA inputs allow connection to common audio components, while the high-level inputs support the integration of new or factory-installed sound systems without additional converters. This ensures flexibility in various setups. The EPS® technology protects the inputs from overload and provides a safe and stable audio connection, which is particularly important under varying loads.

Is the ESX SXT900.4 (24V) suitable for start/stop vehicles?

Yes, the ESX SXT900.4 (24V) is start/stop capable and thus ideally suited for modern vehicles with such technology. The Start/Stop Ready feature means that the amplifier remains stable even during brief power interruptions and quickly becomes operational again when the engine is restarted. This characteristic is particularly important to ensure uninterrupted audio output without the amplifier needing to reconfigure itself at every stop, which is beneficial for vehicle owners with modern development techniques.
