Satisfaction Ensured. Manufactured to the Highest Quality Available. With True Enhanced Performance. Latest Technical Development. High efficiency is a key requirement for amplifiers, particularly when it comes to driving powerful speakers over long periods using the car's battery power. To attain high efficiency, the power supply drive stage employs MOS-FET devices having low internal impedance. This helps preserve the transparency and crispness of the original audio signal for faithful audio reproduction through the connected speakers. Maximum output power is an impressive 1200W (600W x 2), thanks to high efficiency with low heat generation and reduced load on the car battery.When configuring a sophisticated car audio system, line-out jacks make all of the difference. They let you easily connect multiple amps, while keeping the wiring neat for an attractive appearance.In comparison with the midrange and tweeter units, the woofer has a relatively higher moving mass, heavier voice coil and larger inductance, so it needs more current to start moving. This causes the bass to lag behind the mid and high frequencies, resulting in unnatural tonal coloration. Furthermore, because of its longer throw, the woofer's voice coil has a greater tendency to deviate from pistonic motion, resulting in non-linear dynamic distortion. To overcome these woofer shortcomings, "intelligent" bass servo drive circuit can feed very high current at the moment of start-up and instantaneously detect and correct the state of voice coil movement to maintain pistonic motion and avoid non-linearity. The result is bass that is more coherent with the rest of the frequency spectrum, achieving greater fidelity to the original sound.
