Massive Audio H8004 - 125 Watts RMS x 4 @ 4 Ohm 4 Channel Amplifier

The Hippo Series High-Performance Amplifiers are the perfect match to our Hippo Series Subwoofers! For a new generation of sound, these ultra-efficient, super compact amplifiers are designed with Massive Audio’s exclusive "Massive Core" which adds tons of headroom for clean, undistorted, pure sound. The "Massive Core" power supply with oversized toroids and transformers delivers plenty of current to drive even the most demanding woofers and speakers. Top-quality parts and construction ensure years of reliable, trouble-free service. Four-layered circuit boards, with surface-mount computer-assembled parts, are tested as they are placed on the board, to help optimize the signal paths and minimize the need for point-to-point wiring while keeping the board temperature even for more predictable operations. An extended frequency response range from 10Hz up to 20KHz, and architecture that was meticulously designed, ensures ultimate sound quality. To combat thermal runaway, which impacts an amplifier's reliability and performance, Massive Audio uses transistors that are specifically designed, and used as output devices, for audio amplifiers. HIPPO SERIES amplifier transistors employ thermal sensing, bias, and are adjusted in real time. This eliminates the thermal lag often encountered in conventional designs. Most HIPPO SERIES amplifiers use a hybrid cooling system that utilizes both convection cooling combined with cool air coming from below, and active cooling using a state-of-the-art fan. This hybrid system makes the design exponentially more efficient. With the heatsink constantly keeping amplifiers cool, the fans normally operate at their lower and quieter speed. HIPPO SERIES amplifiers are incredibly stable even under low-impedance speaker loads and deliver reliable power with audiophile-quality sound. Additionally, a short path design and redundant systems (with Reactive Load Monitoring and other protective technologies) ensure that peaks are effortlessly reproduced
