The Cambridge Audio MXW70 Compact Power Amplifier delivers exceptional audio fidelity backed by rigorous engineering. Its compact design belies the powerful performance it offers, making it a versatile addition to any audio system.
The MXW70 achieves a power output of 70 Watts per channel at 8 ohms and can reach 250 Watts in mono mode at 8 ohms by utilizing advanced Hypex NCore Class D amplification technology. This technology not only enhances efficiency but also reduces distortion, allowing for smooth and dynamic sound reproduction. With a damping factor greater than 180 at 1 kHz and a total harmonic distortion plus noise (THD+N) of less than 0.015% at 5W/8 ohm, the amplifier can effectively drive various speaker loads while maintaining high fidelity. Its input sensitivity and impedance are calibrated to optimize performance with varying audio sources, ensuring an accurate transmission of audio signals, whether through XLR or RCA connections. The MXW70 also features a premium all-metal construction which contributes to both durability and reduced signal interference, establishing a solid foundation for high-quality sound delivery.
