Hybrid Feedback Digital Amplifier
Hybrid Feedback Digital Amplifier
JVC technologies for satisfying the THX Ultra2 certification
The superior technologies applied for the digital amp combine to lower the total harmonic distortion by a
specific ratio (see the following pages for details). This means when the distortion of input signals are lower,
that of output signals are lower than when input signals have higher distortion. This is why JVC engineers
applied a wide range of quality parts for the A/V receivers. These devices ensure even better sound quality by
sending low-distortion signals to the Hybrid Feedback Digital Amplifier Ver. III.
