VGCA: Variable Gain Control Amplifier
You can achieve a clearer sound by using this feature.
Turning the VGCA on and off
Press [-VGCA –CINEMA BASS].
The indicator lights while the VGCA is on.
How this unit’s VGCA works
Generally, the rate of noise (N) to sound (S) worsens as you lower
the volume on an amplifier. With this unit, however, the VGCA
circuit changes the gain between 0 and –10 dB, thereby maintaining
the same S/N ratio. This change in gain is then maintained as you
continue to lower the volume, allowing you to enjoy a better S/N
ratio than if the feature was off.
