The Phase Linear 400 is the most advanced amplifier that today's technology can produce.
A new generation of extremely fast, high energy silicon output transistors, and a host of new materials and techniques only dreamed of a short time ago has made possible an amplifier with performance characteristics that extend virtually beyond the limits of measurability.
At 20 cycles per second, damping exceeds one thousand.
Distortion is so low that it must be measured with only the finest laboratory equipment.
Continuous power levels can be delivered into 8 ohms from 20 cycles per second to beyond 20,000 cycles per second.
Power output: 210 watts per channel into 8Ω (stereo)
Frequency response: 20Hz to 20kHz
Total harmonic distortion: 0.25%
Damping factor: 1000
Input sensitivity: 1.7V
Signal to noise ratio: 100dB
