ALPINE/LUXMAN D-103
¥ 65,000 (released in October 1985)
Commentary
A CD player from the Brid series.
It is equipped with S. T. A. R. circuit which is Luxman circuit technology.
In this circuit, sharing of the power supply line and ground line of the amplifier stage is avoided, and all lines are connected directly from the reference point to each block and signal path to prevent distortion due to ground fluctuation and realize smooth signal flow in the circuit.
The power supply section completely separates the supply to the digital path from the supply to the analog path to prevent degradation of sound quality such as mixing of pulses into analog signals.
Stable trace performance is obtained by adopting tracking servo for the service circuit.
In the tracking servo, servo gain is set according to the deviation from the information recording track, and tracing capability is improved for all conditions.
A passive filter is inserted immediately after the D/A converter to ensure the quality of the and to ensure the quality of the analog initial signal.
By using earthquake-resistant dampers with excellent vibration absorption at important points, stable operation is guaranteed.
It is equipped with functions such as headphone volume, repeat function, track no, lap time such as headphone volume, repeat function, track no, lap time, Remain time display, etc.
