Frequently Asked Questions about Competition Series GS-28000.1

How does the Competition Series GS-28000.1 achieve a power output of 28000W RMS @ 1 Ohm at 14.4V?

The 1-Channel Amplifier GS-28000.1 utilizes advanced Class D technology, which allows for high efficiency. At an impedance of 1 Ohm and an operating voltage of 14.4V, the amplifier delivers an impressive power output of 28000W RMS. This is supported by the use of 8x100mm² power connections and efficient heat dissipation through the highly durable aluminum die-cast heat sink, which ensures that the amplifier remains stable even under maximum load.

What protection mechanisms are integrated into the GS-28000.1 to ensure safe high power outputs?

The Competition Series GS-28000.1 is equipped with the T.D.O.S. protection circuit, which effectively prevents overcurrent, overvoltage, and thermal overloads. These protection mechanisms are crucial for safeguarding the internal electronics and connected audio components from damage, especially with the high current draw of up to 2600A. Additionally, the 8x100mm² power connections provide a stable power supply and minimize voltage losses, ensuring reliable performance.

How does the Class D topology affect the efficiency and heat generation of the GS-28000.1 amplifier?

The Class D topology of the Competition Series GS-28000.1 significantly contributes to its high efficiency of over 82% at 1 Ohm impedance. The digital switching technology greatly reduces heat generation compared to traditional Class A/B amplifiers. The highly durable aluminum die-cast heat sink supports effective heat dissipation, keeping the amplifier cool even at maximum power output and optimizing efficiency across different impedances.

What frequency ranges does the GS-28000.1 cover and how do HPF and LPF affect sound quality?

The Competition Series GS-28000.1 has a frequency range of 20 to 10,000 Hz. The integrated high-pass filter (HPF) is adjustable between 15 and 80 Hz at 12dB, allowing for the minimization of low-frequency distortion and improving the clarity of the mids and highs. The low-pass filter (LPF) can be set between 40 Hz and 10 kHz at 12dB to attenuate unwanted high frequencies and ensure a precise, clean sound. This enables detailed sound optimization according to the user's needs.

What recommended fuses are necessary for the operation of the GS-28000.1 and why?

The 1-Channel Amplifier GS-28000.1 recommends the use of 4x600A fuses. These high fuse ratings are necessary to handle the maximum current draw of 2600A that can occur during peak loads. Using the correct fuses ensures that the system is protected from overcurrent while providing a stable and uninterrupted power supply for the amplifier, which is especially essential in high-performance competitive applications.

What is the average current draw of the Competition Series GS-28000.1 and what does that mean for installation?

The GS-28000.1 shows an average current draw between 800 and 1200A. This high current requires careful installation with robust power connections, such as the 8x100mm² cables, which ensure a safe and efficient power supply. Additionally, the vehicle should have an appropriate power source and wiring to ensure continuous operation without power loss or overheating. Proper installation is crucial to fully utilize the amplifier's performance.

What dimensions and weight of the GS-28000.1 should be considered when placing it in the vehicle?

The Competition Series GS-28000.1 measures 790mm in width, 225mm in depth, and 70mm in height, and weighs 14Kg. When installing, you should ensure that there is enough space in the vehicle to allow for efficient cooling through the aluminum cast heat sink. The size of the amplifier requires a solid mounting surface to minimize vibrations and movements during driving and to ensure a stable position that facilitates optimal operation and connections.

What power voltages does the GS-28000.1 support and how does this affect the power output?

The Competition Series GS-28000.1 operates with an internal operating voltage of 235/260V as well as an operating voltage between 9.3V and 15.9V. The variable operating voltage allows for flexible adaptation to different power sources and applications. At higher voltages, such as 14.4V, the amplifier can achieve a maximum RMS power of 28000W @1 Ohm, while lower voltages correspondingly reduce the power output. This provides users with the ability to adjust the power to their specific needs.

How do the bass boost settings on the GS-28000.1 affect the audio output?

The Competition Series GS-28000.1 offers a bass boost of 0 to 12dB with a frequency of 45Hz. This setting allows you to specifically enhance the low frequencies to increase bass pressure and make the sound more voluminous. Especially if you enjoy listening to music loudly or prefer dynamic bass lines, the bass boost can help tailor the listening experience to your preferences and achieve powerful bass reproduction without compromising the clarity of the other audio frequencies.

What is the significance of the signal-to-noise ratio (SN Ratio) on the GS-28000.1 and how does it affect sound quality?

The Competition Series GS-28000.1 has a signal-to-noise ratio (SN Ratio) of over 86dB. A higher SN Ratio means that the amplified audio signal is significantly louder than the background noise, resulting in clearer and more interference-free sound reproduction. This is particularly important at high power outputs, as a good SN Ratio ensures that even at maximum volume, the audio quality is maintained and distortion is minimized, contributing to a clean and precise sound image.
