1. The V1.0B mini stereo amplifier uses a highly efficient, fully integrated digital Class-D audio amplifier IC based on a brand-new amplifier technology, supporting a power supply voltage range of 12 V to 24 V, suitable for home and professional audio applications. 2. The V1.0B dual-channel Class-D amplifier uses two Texas Instruments TPA3116D2 chips. The TPA3116D2 is a highly efficient stereo digital amplifier for driving speakers, and its advanced oscillator/PLL circuit uses a variety of switching frequency options to effectively avoid AM interference. High performance effectively improves output power and sound quality. 3. With advanced circuit design, built-in speaker protection circuit and sturdy aluminum chassis, this home Hi-Fi integrated amplifier has clear sound quality, no audible noise, and can remain quiet even when nothing is playing. 4. The V1.0B stereo audio amplifier has extremely low power consumption under all operating conditions. Ultra-high power efficiency and low-temperature operation make the V1.0G very suitable for home audio systems.
