5 Hybrid Feedback Digital Amplifier

JVC-exclusive Hybrid Feedback Digital Amplifier enables a lot more than the compact dimensions of the A/V receivers. Featuring dual analog feedback and digital feedback circuits, this device significantly “brushes up” the input signals, which ensures significantly lowered total harmonic distortion -- to 0.004% -- and superior speaker driveability. The result is high-quality sound matching that from a high-grade analog amp.

The RX-D702 and RX-D402/D401 come with an upgraded “Ver. III” device, which incorporates a wide range of technological improvements for even better sound quality.
