Harman Kardon design philosophy The TC Series amplifiers employ the key Harman Kardon design principles of highinstantaneous current capability (HCC), ultrawidebandwidth, low negative feedback, and fully discrete preamp and output circuitry. HCC (High-instantaneous Current Capa,bility) While reproducing dynamic music signals, the instantaneous impedances of nearly all loudspeakers drop to less than a third of the nominal rating. These low momentary impedances typically require three to six times more current from the amplifier than would a nominal Cohm resistive load. The TC600 amplifier can supply 100 amperes of instantaneous current, while the TC300 and TC304 can supply 50 amperes. This HCC provides control over the low impedance and fluctuating phase angles produced by normally operating speakers, ensuring that your speakers will be able to continually reproduce the entire dynamic range of music without premature clipping or current limiting. Bridgeable All TC Series amplifiers are designed to provide increased power into 2 ohms stereo or 4 ohms bridged. Unlike many lower-quality amplifiers, the TC Series amplifiers can be bridged for increased power. Stable, reliable operation in these higher power modes is assured by the TC Series' wide-margin Safe Operating Area (S.O.A.), which anticipates the toughest operating conditions. Ultrawidebandwidth Unlike conventional automotive amplifiers, the TC600, TC300, and TC304 can reproduce musical frequencies ranging from less than lOHz to more than 100kHz. This ultrawidebandwidth improves the accuracy of reproduction of transient signals and ensures phase linearity. Low negative feedback This design philosophy is used by the world's most exclusive amplifiers. It requires the highest quality internal components, and results in an extremely stable amplifier with unmeasurable TIM distortion and absolutely outstanding imaging characteristics. Fully discrete circuitry Rather than employing inexpensive integrated circuits, which reduce bandwidth and increase required negative
