The Dussun V series is a new kind of large power hyper Class A integrated amplifier. A technically successful adaptive-bias circuit achieves extra-large Class A power output with low power consumption and low heat production. The adaptive-bias circuit permits the amplifier to maintain Class A mode output even if the speaker's impedance drops largely and output power increases several times. This is different from the traditional Pure Class A amps, which inevitably return to Class B when the speaker load impedance goes down.
Special design features include the output stage peak current, which was designed up to 90A, and the transformer capacity per channel, which was designed up to 1,000 watts. In order to increase sound quality and to modify the V6i harmonic spectrum for much lower odd order harmonic wave energy, V8i employs the adaptive-bias circuit with an ideal specification.
A multi-stage power supply and system loop not only increase the V8i signal-to-noise ratio to a higher level but also suppress the AC power source hum, which many times contaminates the purity of the music under a large power output.
The preamplifier stage and power amplifier stage are open to the user, allowing easy use of either. For general use the preamp and power amp stages are linked by a pair of link pins. If the link pins are removed, it is simple for the user to use either the preamplifier stage or power amplifier stage respectively. The volume control is built in the preamplifier stage, so the preamplifier output signal level is controlled by the volume control knob.
