This is a brand new item.
The Gisen Audio MM series are digital high-end power amplifiers with extremely high performance. The power amplifiers deliver the entire output performance at any time without loss of sound. To maximize the headroom, the GISEN Audio MM series has an adjustable signal reinforcement, which optimally interacts in every channel with a Voltage Peak Limit Technology. VPL optimizes the output voltage in each channel for any load, regardless of whether a subwoofer or a high frame is operated. The unprecedented warning functions and protective circuits of the Gisen Audio MM series extend the lifespan of the amplifier and maintain the connected load and amplifier from unwanted failures or service interruptions. Regardless of whether there are incorrect cabling, improper handling or extreme ambient temperatures, the digital power amplifiers of the GISEN Audio MM series signals clear information about existing problems.
