SANSUI DA - α 607i

Commentary

D/A converter that employs balanced output and 8 x oversampling.

It is equipped with a multi-auto-sampling system that automatically responds to 32 khz, 44.1 khz and 48 khz sampling frequencies. All digital sources can be reproduced by simply switching the input selector.
The input sampling frequency is displayed on the front panel.

The digital filter uses an 8 x oversampling digital filter.
This increases the resolution eight times in the time axis direction and reduces the load on the analog filter. This eight times oversampling digital filter improves the filter characteristics with a passband ripple within ± 0.0001 dB and a reduction of -100dB or more outside the audio signal band.

The analog filter has a wide bandwidth corresponding to a sampling frequency of 48 kHz, and uses a third order GIC type that only allows audio signals to pass through a resistor.

The D/A converter is equipped with a high-precision ladder type D/A converter capable of high-speed serial data processing to eliminate the glitch (noise) that accompanies D/A conversion.
By adopting a twin configuration in which the left and right D/A converters are used independently, the phase difference and crosstalk between the left and right channels are reduced and superior sound quality is achieved.
In addition, a cross fine circuit is adopted to suppress 0 cross distortion, and low distortion rate and high SN are obtained.

The power transformer is mounted on the rear panel to eliminate the influence of electromagnetic noise and vibration generated by the transformer on the signal system.
In addition, the interference of digital noise to the signal system is suppressed by the adoption of the analog / digital independent 2-transformer power supply, the complete separation shield of the analog / digital / power supply by the separator, anti-flux chassis, etc.

Equipped with an analog part capable of balanced output and a balanced output terminal, it brings out the capacity of an amplifier capable of balanced input.

Equipped with 4 digital inputs and 2 analog inputs.

A remote control is included.
