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.
