Commentary

This is a pre-main amplifier with Integra technology condensed to a width of 330 mm.

A signal-in-phase transformer is installed to eliminate digital signal interference.

Equipped with a CD direct switch.
The CD music signal is sent directly to the main amplifier via a dedicated volume that is completely independent of other sources, enabling high-purity transmission.

The tone control uses a direct tone circuit, and in addition to bass / treble, there is also a Contrabass that boosts only the very low frequencies below 100 Hz.
