Commentary
A CD player from the Brid series.
It is equipped with S. T. A. R. circuit which is the technology of Brid series.
This circuit eliminates the need to share the power supply line and ground line of the amplifier stage. All the lines are connected directly from the reference point to each block and signal path. This prevents distortion due to ground fluctuation and realizes smooth signal flow in the circuit.
The semiconductor laser pickup uses a high-precision collimator / objective lens with less aberration.
As for the tracking servo, the tracing capability is improved under all conditions by setting the servo gain according to the deviation from the information recording.
The D/A converter uses a 16-bit integration type.
The headphone output has a volume, so you can listen to the sound at a suitable volume.
