TOPPING Mini 300 Compact Desktop Power Amplifier - fully-balanced Class-D Amp, TRS/RCA input, 12V Trigger, Ultra-low distortion, Zero-noise Safe and reliable

<ul><li>Balanced architecture, balanced sound.Inside, the Mini 300 runs a fully-balanced Class-D circuit. That means each channel has its own complete amplification path, eliminating crosstalk and rejecting external noise before it ever touches your speakers. The result is an ultra-quiet floor—124dB SNR and less than 15μVrms of noise—so the only thing you’ll hear is the music itself. Smooth, transparent, and effortlessly controlled.</li><li>Ultra-low distortion.Mini300 exhibits distortion levels close to high-end reference.THD+N <0.0004% @8Ω 5W. This means every musical detail is faithfully reproduced, whether it's subtle instrumental nuances, delicate vocals, or large-scale dynamic music. The result is enhanced depth, and a higher level of audio fidelity.</li><li>Multi-scenario High-power output.Mini300 can deliver up to 140W×2 into 4Ω at 10% THD+N, and still provide 125W×2 into 4Ω even at 1% THD+N. This combination of high power and high fidelity makes Mini300 more than capable of meeting the demanding audio requirements of HiFi music listening or professional monitoring.</li><li>Dual inputs.The rear panel accepts both balanced TRS and unbalanced RCA inputs, no adapters needed. Balanced inputs offer better rejection of interference for longer cable runs, while RCA keeps compatibility with everyday sources. Flip the front switch between BAL and SE to match your source, and you’re good to go.</li><li>Auto-on convenience.The 12V trigger input lets the Mini 300 power on and off in sync with your DAC or preamp—no reaching behind your stack or fumbling for switches. Once connected, it wakes up and shuts down with your system.</li><li>Zero-noise Safe and reliable.Featuring silent power on/off and built-in overheat and overcurrent protection, Mini300 safeguards components from accidental damage, such as excessive volume levels.</li></ul>
