REGULATED SWITCH MODE POWER SUPPLY (SMPS)
One of the design enhancements shared by all of Emotiva’s new XPA power amplifiers is their new, specially designed, high-current, switch-mode power supply (SMPS). Emotiva’s powerful, intelligent new power supply offers all of the benefits of a classic transformer-based design, but avoids virtually all of the limitations. It can deliver over 3 kW of fully regulated power, which ensures optimum performance under a wide range of load conditions, and plenty of dynamic power to ensure that musical peaks will never be compressed or limited. However, it’s also more efficient, more reliable, and much lighter.
CLASS A/B SOUND QUALITY MEETS OPTIMIZED CLASS H EFFICIENCY
The High-Powered Single Channel Modules used in the XPA-7 utilize a fully analog Class A/B output stage, and Emotiva’s highly regarded Soft-Switch™ Optimized Class H power supply topology, which increases their efficiency significantly without compromising their superb Class A/B performance and sound quality. At low power levels, each channel operates on a relatively low supply voltage to minimize quiescent power consumption and standby power losses. Then, when the demand for power increases, it instantly and seamlessly switches to a higher voltage rail to ensure that the signal passes cleanly and without clipping. This process happens on a continuous basis – in real time, allowing greater overall efficiency, cooler operation, longer component life, reduced power consumption, and increased reliability.
