How this unit’s VGCA works
Generally, the ratio of noise to sound (S/N ratio) worsens as you
lower the volume. This unit’s VGCA, however, maintains the same
S/N ratio from the maximum volume level (0 dB) down to a certain
level, and as you continue to lower the volume, this difference is
maintained, allowing you to enjoy better S/N ratios at lower
volumes.
