SANSUI AU - α 607 dr

Commentary

This pre-main amplifier has a simple body and is completed with SANSUI technology.

The amplifier circuit of the amplifier is independent from the ground circuit, and an epoch-making advanced α -X balance circuit equipped with NM-LAPT is adopted.
This circuit has a balanced configuration that transmits and amplifies signals simultaneously and is free from external noise and in-phase distortion. The speaker is driven under the same conditions from both + and - directions by a push-pull method with four amplifiers on the + and - sides of the output.
In addition, the NM-LAPT developed specifically for audio reduces circuit impedance and improves dynamic frequency characteristics.

A closed-loop configuration NEW α -X balanced power supply section fully loaded with high-quality sound components such as custom-made electrolytic capacitors and power transformers provides a stable power supply.

The vibration of the power and signal systems is effectively controlled by a reinforced twin monaural construction with an optimum weight balance, and the vibration transmission path, such as between the volume and the chassis through which all music signals pass, is equipped with an opposed mechanical feedback and is damped by pure copper isolation parts.

We thoroughly pursue the quality of each part such as the part where music signal directly passes and the insulator of vibration dispersion and non-resonance design.

Equipped with Power Amp Direct, which can directly input audio signals to the power amp section.

By setting the CD player to Power Amp Direct, you can record a CD or other source in the background while listening. For example, you can record a CD or other source in the background while playing the source in Normal 1. For example, you can record a CD or other source in the background while playing the source in Normal 2.

Includes 6-channel detent volume, gold-plated input terminal, large speaker terminal and polarity display power cord / AC outlet.
