SIGMA Amp5

Sigma AMP5 FIVE-CHANNEL AMPLIFIER

The Sigma series AMP5 is a 200W/Ch five-channel amplifier derived from the AMP2, but with necessary part and layout changes to accommodate its five-channel architecture. Like the AMP2, it utilizes 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 AMP5’s attributes.

*each channel supports 400W output into 4 ohms but the AC Mains/power
supply cannot support all channels driven simultaneously at this level, which
would require over 2,500W and only occur under a special test condition.
Every channel easily drives lower impedance loads.
