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.
