The BB Key controls the Bass Booster. When the power is turned ON, the Bass Booster is OFF. Likewise, the 3D

Key controls the 3D Effect. When the power is turned ON, the 3D Effect is OFF.

Direct Key Selection Mode

The Direct Key Selection Mode is active when the SEL Pin is set to “LOW”. As the name implies, you can directly

select the sound selection you like (Flat, Classic, Rock, Jazz, or Pops) simply by pressing the respective keys. This

means, that to select the Jazz mode, press the JAZZ Key, Classic Mode, press the CLASSIC Key and so forth. Take

note that when the power is turned ON, the Flat Mode is active. The Bass Booster Function and 3D Effect are

independent of the key / sound mode selected and may be turned On or Off at any time.
