TA-21 is the updated version of NS-20G released in 2021, much progress are acheived in sound quality and circuit perforamce.
Features
Mini size but strong output power: adopting TPA3221 chip, much better than TPA3116 in power and performance, each channel can output up to 100W, easily to drive 3”-10” speakers, low heat emitting even when powering floor-standing speakers.
Stable and better sound quality: Bluetooth 5.0 version chip with DSP (digital sound processing), up to 50ft connection range makes HiFi music with low signal delay, the sound is clear, no pop and no audible noise via Bluetooth input.
Wired and Wireless inputs: with 3.5mm AUX and Bluetooth inputs, can match well with much audio devices to provide better sound quality, exclusively designed for the audiophiles who pursue HiFi sound.

Warm tips:
1. The minimum power that can drive TA-21 amplifier is 50W, default equipped with 24V/3A power supply, which is enough for most home speakers.
2. When plug in AUX cable, TA-21 will default enter AUX input mode. If you want Bluetooth input, please plug out AUX cable.
3. If there is an outage during use, that means the power supply is too small to drive the speaker, please change larger power supply or turn down the volume.
