Classe Sigma AMP5 Multichannel Power Amplifier






Sigma AMP5 FIVE-CHANNEL AMPLIFIER - Clearance stock only 2 available.

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.

All tests un-weighted and 20Hz – 20kHz measurement bandwidth used.
Frequency response 10Hz – 20kHz, -1dB into 4Ω 
Output power 200W rms into 8Ω All channels driven
400W rms into 4Ω Any two channels driven* 
Harmonic Distortion 0.018% @ 1kHz All channelsdriven 
to 1/8th power into 8Ω
Peak Output Voltage 113V peak to peak, 40V RMS no load
113V peak to peak, 40V RMS into 8Ω 
Input Impedance 100kΩ Balanced / 50kΩ SE 
Voltage gain 29 dB 
Input level at clipping 1.4Vrms Balanced/SE
>80 dB below fundamental into 8Ω SE
Signal to Noise Ratio -100 dB at peak output into 8Ω (AES17)
Rated power
200W @ 1/8th power into 8Ω 
Mains voltage 100V - 240V, 50/60Hz
Overall Dimensions Width: 17.00” (433mm) Depth (excluding connectors): 14.57” (370mm) Height: 3.75” (95mm)
Net weight 23.1 lb (10.48 kg)
Shipping weight 30.0 lb (13.61 kg)
*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.
