Digital pianos with 1 pedal input

 

— in this case, it is assumed that the digital piano has one input for connecting an external pedal. Among portable instruments (see "Body"), this feature is typical mainly for low-cost models that are not designed for highly professional performance (although there are exceptions — "genre" instruments, for which the presence of several pedals is not critical). But in stationary digital pianos, the opposite is true: the presence of this input allows you to connect an additional fourth pedal (in addition to the three standard ones installed by definition), which is required specifically for professional tasks.
