Висококачествено мос фет американско стъпало HAFLER DH220-динамичен , детайлен и прецизен звук за ценители-390лв.
The Hafler DH-220 series is one of the most popularly sold amplifiers ever produced. David Hafler produces some of the best sounding, no nonsense audio equipment for the discriminating listener. David Hafler is regarded by many as the father of high fidelity. His design theory: created products that offer elegantly simple circuitry while providing superior sound. Many recording studios in the world have adopted Hafler as their standard. FEATURES: Power Rating: Less than 0.02% total harmonic distortion at any power level up to 100 watts continuous average power per channel at any frequency between 20 - 20 Khz with both channels driven. IM Distortion (SMPTE): Less than 0.005% from 1 to 100 Watts. Typical THD at 100 Watts: 1 Khz - 0.0015%, 10 Khz - 0.005%, 20 Khz - 0.012% Frequency Response: -3db, 1 Hz to 100 Khz at 1 watt, +/- 0.5db, 10 Hz to 40 Khz at 100 watts. Typical Channel Seperation: 20 Hz - 66 db, 1 Khz - 66 db, 20 Khz - 60 db Signal to Noise Ratio, unweighted: < 100 db at 100 watts Input Impedance: 22,000 ohms (standard for most preamplifiers) Input Sensitivity: 1.5 volts rms for 100 watts Damping Factor: 150 to 1Khz & 50 to 10 Khz Rise Time: 10 Khz, 60 volts peak to peak square wave: 2.5 u sec. Slew Rate: 10 Khz, 60 Volts peak to peak square wave: 25 V/u sec Semiconductor Complement: 26 transistors, 8 power Mosfets, 24 diodes, 4 zener diodes, 1 diode bridge. Power Consumption: Quiescent: 100 VA: 100 Watts, 370 VA Size: 5 1/8� high, 16 � wide, 10 �� deep Net weight: 26 lbs,
