• Power reverse connection protection, speaker short circuit protection, power-on and power-off surge protection, no ‘POP’ sound when switching on and off. • Uses two 1000uF/35V power filter capacitors, effectively enhancing low-frequency performance. • Uses shielded inductors instead of ordinary inductors, minimizing interference between channels and making the sound quality purer.

• The recommended power supply is 24V, do not exceed this voltage! • Do not short-circuit the audio outputs to each other or to the ground! • Please check carefully before powering on to ensure the wiring is correct before turning on the power!
