FAQ
Q: Is it mandatory to use with a subwoofer? A: No. If you only connect left and right speakers, it works as a standard 2.0 stereo system; the subwoofer port can be left unused. If you want to upgrade for deeper bass later, simply add a subwoofer to turn it into a 2.1 system, offering great flexibility.
Q: Does Bluetooth 5.2 deliver worse sound quality than wired connection? A: No. This amplifier uses Qualcomm QCC3040 Bluetooth 5.2 chip, supporting high-definition codecs including aptX-HD and aptX-Adaptive. It supports sampling rates of 44.1K–48K /16–24bit. If your playback device supports the corresponding protocol, the wireless listening experience is close to wired audio.
Q: What is the difference between 2.1 channel and regular 2.0? A: 2.0 has only left and right channels, while 2.1 adds an independent subwoofer output channel. When low frequencies are handled by a dedicated subwoofer, movie explosion scenes, gaming impact and electronic music will deliver much more powerful bass. This is the core advantage of this unit compared with ordinary desktop amplifiers.
Q: Will it get very hot or produce background noise during operation? A: No. TPA3126 is the 3rd-generation Class D amplifier architecture with high efficiency and low heat generation. Temperature rise remains minimal even after long hours of use. It achieves SNR of 100dB for an ultra-quiet background. Just place it in a well-ventilated area and do not block the cooling vents.
