Comparison of Speaker Driveability
RX-D702 RX-D402
Usually, speaker impedance
fluctuates according to the
frequencies of audio signals.
This “frequency response” of the
speaker in turn fluctuates the
levels of audio signals. How
effectively an amplifier can control
these fluctuations is called
“speaker driveability”.
The feedback processes of the
Hybrid Feedback Digital Amplifier
significantly improve the speaker
driveability, retaining the same
output level across the
frequencies.
