It provides two types of key selection mode namely: the Direct and the Cyclic. These two key selection Modes are determined by SEL pin. Please refer to the table below: Key Selection Mode Direct Cyclic SEL Pin Low Floating/High Description Press FLAT key to activate Flat Mode Press ROCK key to activate Rock Mode Press POPS key to activate Pops Mode Press CLASSIC key to activate Classic Mode Press JAZZ key to activate Jazz Mode ...Flat→ Rock →Pops→ Classic→ Jazz →Flat→Rock... Note: 1). The Bass Booster can be controlled in the same manner under the Direct or the Cyclic Key selection Mode. To turn the Bass Booster ON or OFF, press the BB Key. 2). Under the Cyclic Selection mode, press the CYC Key, to go to the next sound selection. 1. CYCLIC KEY SELECTION MODE As seen in the table above, the cyclic key selection mode is active when the SEL pin is floating or “high”. Under this mode, any of the sound selections (Flat, Rock, Pops, classic, Jazz) may be selected by pressing the CYC key. The default value is the Flat Mode. This Means that when power is turned ON, the mode is active. Pressing the Cyclic Key lets you go from one sound selection to the other in the following order: Flat→ Rock →Pops→ Classic → Jazz. That is, press the CYC key to activate the next mode. The BB key controls the Bass Booster. When the power is turned ON, the bass Booster is OFF. 2. DIRECT KEY SELECT.
