2013年8月15日 · Things changed in 1967, when Crown produced the DC300, the first reliable, solid-state, high-power amplifier. Rated conservatively at 150 watts per channel, it also offered low distortion and noise. Two generations of “large” Crown amplifiers preceded the DC300, and were made only in prototype quantities.

2017年4月12日 · Using the DC-300 with a pair of 30W-capacity speakers, without protective fuses, is simply asking for a catastrophe, for all it takes is one loud pop, from a noisy switch or an ungrounded phono input or a stylus touched delicately to the rough edge of a disc, and $600-worth of loudspeaker can go up in a puff of smoke.

2024年9月8日 · It got me wondering what the differences are between it, and the DC-300, and the later DC-300 series II. I noticed that the series II has the distortion comparison circuitry that is present in later amps, like the com-tech series. Otherwise is there any big difference in the specifications, the sound quality, and the transistors used?

precision amplification of frequencies from DC to 20 KAz with operation into loads of 4 ohms and higher. The unit. shorted loads by an instantaneous acting and resetting V-I (volt-ampere) limiter having no obnoxious muting or program delays. A pair of thermal switches remove power from the unit if overheating occurs due to insufficient ventilation.

The DC-300 is a dual channel, high power amplifier for precision amplification of frequencies from DC to 20KHz. The unit features extremely low harmonic and intermodulation distortion, very low noise, highest damping factor, and quality parts and workmanship.
