Pre-main amplifier with high response speed LED power indicator and microphone mixing circuit.
It is equipped with an LED power indicator with a response speed of 200 μ sec that displays music signals with 5 LEDs arranged symmetrically.
Uses a low distortion and low noise design that inherits the concept of 99A (SU-8099) Concentrated Power Block.
