Maestro INT
Commentary

This is a reference integrated amplifier developed by integrating the technologies of the audio analog composer series.

It is equipped with a phono equalizer that supports both MM and MC.

Dual monaural configuration with left / right channels, preamplifier and power amplifier independent power supply is adopted.

One balance terminal is mounted on the line input of the preamplifier section.

It can be developed into a bi-amplifier system by utilizing the pre-out terminal.

It comes with a remote control for volume adjustment, muting operation and function switching.
