The development of the DC power amplifier can be counted as one of our most significant engineering successes, because it provides an almost perfect linear frequency response that starts virtually from 0Hz. What this means is that the signal amplified has effectively the same waveform as that at the input terminals. The amplifier maintains extremely low distortion right down to the ultra-low frequency range. With excellent phase and transient characteristics - the response in actual conditions of musical reproduction - the sound that you hear is perfectly natural. The direct-coupled amplifier consists of a three-stage differential circuit (with a dual-gate FET in the first stage) and our power amplifier circuitry, assuring ample, highly stable, effective power output. To safeguard all circuits, and your precious speakers, there's a built-in limiter protection circuit and protection relays. With phase and transient distortion both at negligible levels, the Kenwood KA-7100 provides a refreshing clarity and roundness of sound even at high volume levels.
