1. Multi-channel power distributionLow-frequency and high-frequency power distribution: Full-range active speaker amplifiers usually adopt a frequency division design to process low-frequency and high-frequency signals separately. The low-frequency part usually requires a higher power output (such as 500W), while the high-frequency part is lower (such as 200W). This distribution ensures the balance of bass and treble, avoids power waste, and improves audio quality.Single-channel and multi-channel output: Some high-end amplifiers support multi-channel output (such as 2.1, 5.1 or 7.1 channel systems), and each channel can provide different power output as needed to meet the needs of different speaker systems.2. Dynamic power management (DSP)Automatically adjust power output: The digital signal processor (DSP) can dynamically adjust the power output according to the changes in the audio signal. For example, when playing the bass part, the amplifier may increase the low-frequency power output; while playing music in the higher frequency band, the system reduces the low-frequency power and increases the high-frequency output.Preset mode: Many speaker amplifiers support a variety of preset sound effect modes (such as EQ, delay, noise gate, etc.), which not only adjust the sound quality, but also optimize the power output to adapt to different environments and needs.3. Power regulation functionAdjustable power mode: Some full-range active speaker amplifiers are designed with manual or automatic adjustable power function, which allows users to adjust the power output according to the size of the venue or specific needs. For example, in a smaller venue, a lower power output can be selected to avoid sound quality distortion; in a large venue, a higher power output may be required.Stereo/mono mode: By switching between stereo or mono mode, the speaker system can adjust the power distribution according to actual needs. For example, in mono mode, the system's power output is concentrated in one channel, while in stereo mode, the power output is balanced to two channels to adapt to a wider range of sound output.4. Efficient power management (SMPS and LLC power supply)Switch mode power supply (SMPS): SMPS is an efficient power supply design that supports the amplifier to work stably under various power requirements by stably providing different voltages and currents. The high efficiency of SMPS reduces energy loss and improves the overall reliability of the system.LLC high-efficiency resonant power supply: LLC power supply reduces losses and improves power conversion efficiency through resonant technology. It can dynamically adjust according to the output power demand, thereby effectively supporting high power or instantaneous power changes.5. Protection functionAutomatic power protection: Full-range active speaker amplifiers usually have overcurrent, overheating, and short-circuit protection functions. These protection functions can automatically limit the output when the power exceeds the set range to prevent equipment damage.Limiter function: The amplifier may have a built-in limiter. When the power is too high, it will automatically limit the output to avoid system overload and protect the speaker from damage.6. Signal and power controlEQ (equalizer) adjustment: Through the audio processing function of DSP (such as equalizer adjustment), the amplifier can optimize the frequency response and audio effect, and adjust the power output of different frequency bands. For example, when the bass needs to be strengthened, the low-frequency power output is automatically increased to enhance the bass effect.Volume control: Independent control of bass volume and treble volume can help users fine-tune the volume of different frequency bands, thereby affecting the power output to ensure the balance of sound effects.
1. Provide stable power supplyLLC high-efficiency resonant power supply can provide stable and constant voltage and current output for powerful subwoofer system. This is especially important for subwoofer system, because subwoofer needs high-power power supply to drive speakers to produce strong low-frequency sound effects. The stability of power supply ensures that subwoofer system will not have insufficient power or unstable power supply when under high load or sudden volume changes. 2. High efficiency and low energy consumptionLLC resonant power supply's high-efficiency conversion technology reduces energy loss and heat generation. This is crucial for subwoofer system, because subwoofer system usually needs high-power power supply support, lower energy loss can effectively reduce power consumption, extend the service life of equipment, and reduce the impact of unnecessary heat on equipment and environment. 3. Improve audio performanceHigh-efficiency power supply can provide clear and distortion-free power supply, avoiding the interference of power supply noise on sound quality. In subwoofer system, low-frequency effect has a great impact on sound quality. LLC high-efficiency resonant power supply reduces electromagnetic interference and noise pollution, ensures clear and accurate output of audio signals, and thus guarantees the sound quality performance of subwoofer. 4. Reduce electromagnetic interference (EMI)The LLC power supply's resonant technology can reduce electromagnetic interference (EMI) during the power conversion process. In a subwoofer system, electromagnetic interference may affect the quality of the audio signal, causing distortion or noise. The LLC power supply reduces this interference by optimizing the switching process, allowing the subwoofer to provide clearer and purer low-frequency sound effects. 5. Support high power outputSubwoofer systems have high power requirements, especially when heavy bass is played, the power consumption is large. The LLC high-efficiency resonant power supply can efficiently support high power output without overheating or power instability, so it is suitable for high-power subwoofer systems to ensure the reliability and continuous performance of the system under high load. 6. Reduce heat generationThe LLC high-efficiency resonant power supply reduces the heat generation of the power module by optimizing the energy conversion process. Subwoofer systems often need to operate for a long time, especially in large concerts or venues. If the equipment generates too much heat, it will not only affect the sound quality, but also cause the system to overheat and malfunction. Therefore, the low heat output of the LLC power supply provides a longer working cycle and higher stability for the subwoofer system. 7. Small size and high power densityLLC power supply has high power density and can provide high power output in a small volume. This is especially important for subwoofer systems, because subwoofers require strong power support, but usually have restrictions on the size of the equipment. The high power density LLC power supply allows the subwoofer system to ensure output power while reducing the volume, making it easier for system integration and installation.
