About the MC2 Audio E Series
The MC2 Audio E Series comprises lightweight, high-power switch mode amplifiers designed for reliability and sonic performance. Models include the E15, E25, E45 and E4-75, which feature MC2 Audio's proprietary current-driven output stages for high-definition sound across the full audio bandwidth. The E90 and E100 are Class D designs offering higher power and increased efficiency while retaining the range's sonic qualities. The E100, the most powerful four-channel amplifier in the series, uses a dual feedback loop Class D topology and a resonant switch mode power supply to deliver over 2500W into 4 ohms with all channels driven, and up to 2 x 7400W bridged at 4 ohms. Sophisticated limiters linked to output current monitors and the power supply keep operating conditions safe at all times without compromising sonic transparency.
MC2 Audio E Series — buyer FAQs
What is the MC2 Audio E Series and what models does it include?
The MC2 Audio E Series is a range of lightweight, high-power switch mode amplifiers. It spans seven models: the E15, E25, E45, E4-75, E60, E90 and E100. The E15 through E4-75 use proprietary current-driven output stages, while the E90 and E100 are Class D designs built for higher power output and increased efficiency across demanding applications.
What sets the Class D models apart from the rest of the E Series range?
The E90 and E100 are Class D amplifiers, separating them from the current-driven output stage models lower in the range. The E100, the most powerful four-channel amplifier in the series, uses a dual feedback loop Class D topology and a resonant switch mode power supply, allowing it to deliver over 2500W into 4 ohms with all channels driven and up to 2 x 7400W bridged at 4 ohms.
How does the switch mode power supply in the E Series handle high-demand audio?
The switch mode power supply is designed to deliver high peaks without perceptible bass sag and operates at very low distortion. An intelligent limiter, linked to output current monitors and the power supply, keeps both mains input and output currents within a safe operating area at all times while maintaining transparent sonic performance under sustained or difficult load conditions.
What should I check when buying a used MC2 Audio E Series amplifier?
Check which model in the range is being sold, since power output and output stage topology differ significantly across the E15, E25, E45, E4-75, E60, E90 and E100. Confirm the number of channels and that all channels function correctly.
