Design Aspects of PX-770

The greatest design attraction of this PX 770 series is the integrated cabinet set and triple pedal unit. The minimalistic design considerations with lesser seams make the model more user friendly than the previous versions. The wooden texture offered on the cabinet helps in embracing an elegant and royal appearance. The inbuilt sliding cover helps to maintain the keys without any specks of dust. The whole package comes as separate functional modules, but the assembly of the whole piece is very easy and within half an hour one can do it.

The small dimensions of the piano set (54.7” X 11.7”) enable it to accommodate in small spaces. The peculiar designing with the left side alignment of the control elements make it more clutter-free.  This series is available in three different appealing colors- white, black, and brown. The labeling above the different functioning keys at the setting side helps in easy navigation.

The Key System

The fully weighted 88-key functioning ensures an unparalleled performance of PX 770. Similar to all the Casio digital pianos; it works through the tri-sensor hammer action. Unlike the springs, these hammer action recreates the original acoustic piano sound. The scaled hammer system works in a weighted manner where the one can find heavier keys at the lower notes and lighter keys at the higher side. The intelligent touch sensor system produces volume changes according to the pressure you apply to each key.

It also has the provision to create equal volumes on all touches by turning off the touch sensitivity. The moisture absorption competency of the ivory and ebony textured key-tops is appreciable. With all these features on the keyboards, it offers a realistic and enjoyable playing experience to both the players and listeners. The richness of the conventional wooden keys is maintained even in the plastic keys with the weighted keys.

Speakers and Volume

The invariable sound eminence across any volume at variant pitches is a very attractive feature of this product. Though it uses the same speaker as that of the lower Px-160 series, the versatile cabinet design with bigger keyboard blocks helps it produce resonant sound. It accommodates 2 speakers with 8W amplification each, delivering an output of 16 W which is quite decent for small indoor performances.

The Casio’s own multi-dimensional morphing AiR sound sourcing is used in the PX 770 series also. As we know, it offers the prime quality samples with its elevated memory capacity. Without compromising the quality of the output sound, the original piano sound is reproduced with the lossless audio compression technology. The player can experience the soft pianissimo to powerful fortissimo variations in the product. One can expect 19 sounds from different other instruments in the PX 770 series. The chorus feature delivers a wealthy sound with different pitch and tone variations in each note.
