Classe’ Audio Sigma AMP5 - 200 watt five channel power amplifier on this listing.  .  The Sigma AMP5 was a display model and demonstrated when customers wished to listen to the amplifier. Original box and packaging come with the Sigma AMP 5.  This is a digital engineered amplification but does not sound digital at all.   The amplifier is a 8.5 out of 10 condition. Warranty comes with the unit.

Shipping – Included with purchase of the unit within most contiguous US states(lower 48 states) only. Shipping cost is added to buyers in Alaska, Puerto Rico, Hawaii,  Guam and Virgin Islands.

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.
