Product Description
What are the features of S series amplifier?
1,S series switching power technology takes your audio to an entirely new level. Delivering tighter bass and clean, transparent highs, it also cuts waste heat, boosts reliability, and eliminates unwanted noise and hum. 2,It  is a revolutionary switching power supply technology that provides ample current to the audio power circuitry by charging the supply rails 230,000 times per second through an ultra-low noise impedance circuit. Unlike amplifiers that use conventional supplies, the audio signal is never starved prematurely and remains crisp and clean.
