equipment remarkably.
QA100 designed as open loop digital circuits, thus there is no stable problem even in
driving speakers with very low impedance. Moreover DSP technology is employed to
correct the expected deviation on the final outputs that made a significant
improvement for the amplifier’s line output characteristics.
