This power capability not only allows for excellent sound output but also provides high adaptability to various audio systems. With optimized RMS power at this voltage, the amplifier can particularly showcase its strengths in demanding audio setups, ensuring detailed audio playback. The high power is a testament to the performance of the Stetsom HL series.

What features do the crossovers of the HL 1200.4–1OHM offer?

The crossovers of the Stetsom HL 1200.4–1OHM are designed for versatility and adaptability. You have the option to choose between low-pass, high-pass, and flat (full-range) settings, which means you can precisely adjust the frequency response of the amplifier to match your speaker arrangement and audio preferences. The low-pass filter offers a crossover frequency of 90 Hz, ideal for bass applications, while the high-pass filter also operates at 90 Hz to excellently reproduce highs. These customization options ensure optimal performance in various musical scenarios.

What is the signal-to-noise ratio of the Stetsom HL 1200.4–1OHM?

The signal-to-noise ratio of the HL 1200.4–1OHM Amplifier from Stetsom is more than 90 dB. A higher signal-to-noise ratio is essential for clear audio playback, as it indicates the ratio between the useful audio signal and unwanted background noise. A value of over 90 dB suggests that the amplifier is capable of delivering a very pure sound, which is particularly important in high-quality audio systems. This means that even at high volumes, the signal is largely free from disturbing background noise, significantly enhancing the listening experience.

What are the power supply requirements for the HL 1200.4–1OHM?

The HL 1200.4–1OHM from Stetsom requires a supply voltage in the range of 9 to 15 volts. This allows for flexible integration into various electrical systems, as found in many vehicles. The consumption of the Amplifier varies depending on the signal: with music signals, the consumption is 57 A, while it reaches 114 A with bass signals. This variability ensures that the Amplifier operates effectively under different operating conditions. A reliable power source is therefore crucial to utilize the full power without losses.

Are the dimensions of the Stetsom HL 1200.4–1OHM suitable for my car?

The dimensions of the Stetsom HL 1200.4–1OHM Amplifier are 66 mm in height, 206 mm in width, and 216 mm in depth. These compact measurements allow for easy installation in many vehicle models, especially those with limited space. When positioning in the car, it is important to ensure that there is adequate ventilation to avoid overheating. Since no specific car brands are mentioned, suitability should be individually checked based on these dimensions in the vehicle console or trunk area.

What channel configurations does the Stetsom HL 1200.4–1OHM support?

The Stetsom HL 1200.4–1OHM Amplifier is equipped with 4 channels, which can be flexibly divided into front (FRONT) and rear (REAR) channels.

Additionally, it is possible to bridge two channels into a more powerful mono channel, allowing for an output of up to 2 x 700W RMS at 13.8V in bridge mode at 2 Ohm.

What impedance do the audio outputs of the HL 1200.4–1OHM support?

The Stetsom HL 1200.4–1OHM was specifically designed for use with speaker systems of a total of 1 Ohm. This low impedance allows the Amplifier to deliver high output power, which is particularly important for performance-oriented audio systems. Such robust performance at such a low impedance is typical for Amplifiers in the HL series, whose design and technical finesse are precisely aimed at ensuring top-notch audio playback. The accurate sound reproduction is especially appreciated in complex audio tasks.

What harmonic distortion does the Stetsom HL 1200.4–1OHM have?

The harmonic distortion of the Stetsom HL 1200.4–1OHM is below 0.9%, indicating excellent sound performance. Harmonic distortion describes disturbances in the audio signal that could affect sound quality. A value below 0.9% is very low and means that the Amplifier reproduces audio signals with high precision and an extremely clear sound. This is particularly important for music playback at high volumes or in demanding audiophile setups, where detail accuracy and sound purity are crucial.

What input sensitivity does the HL 1200.4–1OHM amplifier offer?

The Stetsom HL 1200.4–1OHM offers an input sensitivity of 0.2 V, providing high flexibility regarding the choice of source devices. A low input voltage value means that the amplifier delivers sufficient power even at low input signals. This is advantageous when working with different signal sources that may not all provide a high output level. Thus, you can combine the amplifier with both conventional car radios and professional preamplifiers to always achieve optimal results.

How does the frequency of the HL 1200.4–1OHM affect the sound?

The frequency range of the Stetsom HL 1200.4–1OHM amplifier spans from 10 Hz to 26 kHz, providing complete coverage of the audible spectrum and beyond.
