Sigma AMP2 TWO-CHANNEL AMPLIFIER
The Sigma series AMP2 is a 200W/Ch stereo amplifier utilizing switching technologies for both power supply and amplification stages. A Classé-designed switch mode power supply with Power Factor Correction makes over 1,000W of clean and stable power available while being both compact and efficient. A new class D amplifier topology provides wide dynamic range, smooth and extended frequency response and rich harmonic detail to yield stunning sonic performance. The efficiency of class D adds efficiency, low heat dissipation and relatively small size to the list of the AMP2’s attributes.
