ONKYO Integra D-655NII

Commentary

A crossover network that enables strict control such as adjustment of various characteristics in order to realize multi-channel playback that is closer to the ideal.

By adopting a dual channel system with independent power supply circuits on the left and right sides, the effect of interference between channels on sound quality is prevented.

The filter circuit uses a newly designed Darlington constant current load filter.
In addition, all filter capacitors, including the coupling, use film capacitors with an extended foil structure that have little effect on sound quality.

A transient killer circuit using a lead relay prevents a click when the switch is ON/OFF.

The cutoff frequency can be independently variable for both high cut and low cut.
Each filter has eight built-in frequencies in increments of 1/2 octave, and also has two additional frequency reserve positions (AUX) that allow you to incorporate elements of any value.

The slope characteristics can be independently switched to 2 stages of 12dB/oct. and 6dB/oct.

When the attenuation slope is 12dB/oct., the damping coefficient can be switched in 4 stages from 0.7 to 1.0.
This allows you to change the shoulder characteristics and make subtle adjustments at the crossover point.

The level can be adjusted up to -20.5 dB in 0.5 dB steps using a precision trimming 43 contact attenuator for each band.
