The design concept of this Class A/B amplifier generation is strictly for the purist, without superfluous features, and concentrates on quality, sound and high output power. The X-Tremes generate an awesome amount of power – so much 'kick' from such a small volume is seldom found. This is made possible by the use of modern full MOSFET circuitry not only for the power supply but also for the output stage. The final amplifier stage uses a quasi-complementary N-channel MOSFET layout that stands for high efficiency with very high stability.
All four models are exactly the same size at a very compact 38.8 x 18 cm. The amps are externally fused at 80 A, so no wonder that ultimately there is about 800 watts total output power available at the speaker outputs on each model. In particular, the 5-channel is a superlative 'power house'. However, the 4-channel model EA4150XT with 4 x 125 W into 4 ohms and a formidable 4 x 200 W into 2 ohms is also certainly no 'pussyfooter' either.
High quality RCA sockets, fully encapsulated terminals for the direct connection of 25 mm² power and 6 mm² speaker leads, high pass, low pass, subsonic and band pass filters together with an external remote level control round off the equipment of these premium amplifiers. In addition, the mono and 5-channel models have a variable phase shift.
