Commentary

This is a device amplifier that combines a multi-channel Divider with an additional power amplifier to complete Onkyo's unique multi-step-up system.

The divider section uses a dynamic dividing system to take advantage of the characteristics of speakers.
This is a method of controlling the high-cut and low-cut at the crossover frequency independently, which makes it possible to make the characteristics flatter.

Cascade connection is also possible by increasing the purchase of Integra 624.

The power amplifier section is a Integra 701 series direct-coupled differential amplifier circuit for all stages.
