X-Treme Power Amplifiers

EMPHASER Xtreme amps inspire with musicality and dynamics, high efficiency and enormous power outputs, but also with their compact design: Who still says that for 800 watts total output power at the speaker outputs of every model, the power amps have to be big and unwieldy?

  • Productinformation

    Great 3D effect music with homogenous mid and high frequency ranges, backed by a punchy, fat bass with enough power reserve for extended bass sessions – for a car audio concept, where you want the focus to be on a cool punchy sound, XT power amps from EMPHASER are a perfect basis.
    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 MOS-FET circuitry not only for the power supply but also for the output stage. The final amplifier stage uses a MOS-FET layout that stands for high efficiency with very high stability.
    EMPHASER‘s power units score with sensational sound and enormous output power relative to their dimensions. 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 @ 4 ohms and 4 x 200 W @ 2 ohms is also certainly no ‘pussy­footer‘ either.
    Equally convincing is the elegant, timeless design with the white illuminated EMPHASER logo. But under the heat­sink – beside SMT components throughout for the active crossovers and the generous power supply – you also get a great deal for your money. The internal layout is very clean and the build quality impressive throughout.
    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 amps. In addition, the mono and 5-channel models have a variable phase shift.
