The Stetsom PA2500.2 provides an output power in stereo mode of 2 x 1375 W RMS at 1 Ohm and 2 x 940 W RMS at 2 Ohm with a voltage of 12.6 V. In bridge mode, it delivers 1 x 2650 W RMS at 2 Ohm. With an increased voltage of 14.4 V, the power in stereo mode increases to 2 x 1600 W RMS at 1 Ohm and 2 x 1200 W RMS at 2 Ohm. These specifications allow for flexible adaptation to different requirements and ensure stable and powerful audio performance. Thus, the PA2500.2 offers excellent performance at both low and higher voltages.

What frequency ranges does the PA2500.2 Amplifier cover?

The Stetsom PA2500.2 Amplifier covers a frequency range from 10 Hz to 11 kHz. This allows for a very broad audio coverage, capable of reproducing both lower bass frequencies and high tones brilliantly and distinctly. The amplifier supports a variety of audio profiles and music genres through this frequency range, making it suitable for different applications in the car audio sector. Whether strong percussive bass lines or detailed mid frequencies, the PA2500.2 offers the flexibility and performance for an impressive listening experience.

How is the PA2500.2 tuned for specific regions?

The Stetsom PA2500.2 has been specifically developed for the demanding car audio profile of the Brazilian Northeast region. This regional tuning includes sound adjustments tailored to local listening habits and preferences. Additionally, the amplifier is flexible and adaptable to other regional requirements, making it particularly versatile. With the pre-EQ channels for bass and mid EQ, it offers optimized frequency settings that allow the sound character to be individually adjusted and enhanced according to the region. This feature makes it ideal for global applications.

What channels does the Stetsom PA2500.2 offer and how do they work?

The PA2500.2 from Stetsom features two main channels: a Bass EQ and a Mid EQ. These channels provide precisely controlled frequency adjustments using an integrated 3-band equalizer to clearly highlight bass and mids. Additionally, a FLAT mode offers linear amplification for a completely uncolored signal. Therefore, the amplifier is ideal for users who prefer a specific sound signature, as well as for those who desire an uncompromising, neutral sound. Each channel has been carefully designed to ensure optimal audio playback in various audio settings.

What signal-to-noise ratio does the PA2500.2 offer?

The Stetsom PA2500.2 offers a signal-to-noise ratio (S/N) of over 90 dB, indicating extremely clear audio output without disturbing background noise. This significantly enhances sound quality by ensuring that music output is clear and distortion-free, even at high volumes. An S/N ratio of this magnitude supports fidelity in both quiet and loud passages, ensuring that the amplifier can be used in very demanding listening environments. High clarity and precision of audio playback are thus guaranteed.

What input and output impedances does the amplifier accept?

The Stetsom PA2500.2 accepts an input impedance of 15 kOhm, making it compatible with a variety of input signals. The output impedance is 1 Ohm in stereo mode and 2 Ohm in bridged mode. These specifications allow for flexible adaptation to different speaker systems and amplifier settings. The varying impedance values ensure optimal energy transfer and efficient power distribution to the connected audio components. Thus, the amplifier can be used flexibly in various audio installation configurations.

What is the power consumption of the PA2500.2 during music playback?

When playing music signals, the Stetsom PA2500.2 has a current draw of 150 A at a voltage of 12.6 V. This current draw is an indicator of the power consumption of the Amplifier during operation. Such capacity ensures that the Amplifier has high power reserves to reproduce demanding music pieces dynamically and convincingly. This ability to operate efficiently under high load makes the PA2500.2 ideal for users seeking the highest sound quality under heavy load. It promises consistent audio quality without loss of performance.

What are the dimensions of the PA2500.2 Amplifier?

The Stetsom PA2500.2 has a width of 246.5 mm, a length of 324.5 mm, and a height of 77.5 mm. These compact dimensions allow for easy integration into various vehicle types without taking up much space in the interior. Weighing 5.4 kg, the Amplifier is easy to handle and install. Due to its small size, the PA2500.2 is particularly suitable for installations where space is limited, yet it still delivers exceptional performance in terms of its audio capacity.

What is the THD+N value of the PA2500.2 and why is it important?

The THD+N (Total Harmonic Distortion plus Noise) value of the Stetsom PA2500.2 is ≤ 1%. This low value is an indicator of the excellent quality of audio playback, as it describes how much distortion and noise occur in the output signal of the Amplifier. A low THD+N value means that the reproduced music remains true to the original and minimizes any unwanted distortions. This is particularly important for audiophiles who value precision and clarity, as distortions can significantly affect sound quality. A ≤ 1% value is therefore excellent.

What operating voltage does the Stetsom PA2500.2 require?

The Stetsom PA2500.2 Amplifier requires an operating voltage of 9 V to 15.5 V DC. This voltage flexibility ensures operation in different electrical environments, making it versatile for use in a car or in a specialized audio setup. The ability to operate within a wide voltage range ensures functionality even under variable voltage demands. This also means increased tolerance to voltage fluctuations that can often occur in vehicles. Stable operation is guaranteed even under various conditions.
