From the 88-key fully-weighted keyboard to the newly added features, the DGX-660 is a quality digital piano capable of fulfilling the grand elements of music needed from a digital piano.

Yamaha DGX-660 has an increased polyphony compared to the DGX-650 model. The polyphony reaches 192-note maximum from a previous 128. Yamaha Educational Suite (Y.E.S.) which should be very useful to beginners is also another fantastic feature to look in to, and we are going to talk about that later in the review.

Features of the Yamaha DGX 660

Features are considered amongst the most essential parts within any digital piano, and this is true since they are responsible for sound quality, performance, and much more. Yamaha, for that fact, has never disappointed in delivering market quality pianos with digital features hence, making the brand maintain a competitive, productive business. Yamaha has for a long time been producing some good pianos with excellent features. We are going to outline these features below.

Specs

Just like the DGX-650’s amazing specs were, so are the new model DGX-660’s are but on this model, they are a bit more detailed to fit the user’s specifications. There’s a vivid difference seen from the height, depth, size, and also weight of this DGX-660. The piano is 5.7” high without a stand and 29.9” high with the stand included, and for an 88-key keyboard, it’s actually standard height.

For the width, the DGX-660 is 55” wide, and the depth goes up to about 17.5” deep. Although the DGX-660 is released under the Portable Grand piano line, it might be a bit bulkier to consider moving it around more often. This is made a reality due to its weight that is 21kgs (46lbs) without the keyboard stand. Now with the stand, it gets heavier to about 28kgs (61lbs).

Design

Yamaha DGX-660 Digital Piano

The DGX-660 is bigger and heavier than other models released under the portable line. The design for that matter is one to talk about. It has a sturdy, well-built standard stand to offer needed support to the piano considering its weight. The stand is available in both black and white colors and consists of wooden side panels.

The DGX-660 has a 320×240 LCD screen which creates a user-friendly experience for the keyboard. In the screen, a pianist can observe the notes they are playing and those supposed to be followed, lyrics of songs, scores and the default settings on the keyboard.

Among the design features is the Yamaha Educational Suite (Y.E.S.) which promises excellent advantage to the beginners as it offers quick, easy-to-learn lessons. The long term pianist has also been considered by a new additional feature Yamaha developed. It is called the Piano Room which has its dedicated button, and once the button is pressed, it activates the optimum function of the piano.

Keyboard

The keyboard is where it gets touchy, and it has a lot to offer. The DGX-660, as mentioned earlier, has an 88-key, plastic, touch-sensitive fully-weighted keyboard with Graded Hammer Standard (G.H.S.) action. The G.H.S action utilizes its effect which is connected to the keys in order to produce an acoustic piano feel.

The action explains why there is a heavier touch in the low end, which then becomes progressively lighter in the higher ranges. The touch-sensitive feature acts in a way that when you press the keys harder, the sound also gets louder. That, in turn, gives the total user control over the expressions and dynamics.

However, the keyboard sensitivity may be adjusted to suit your customs of play. This is made possible by four pre-set settings, namely;

  1. Soft
  2. Medium
  3. Hard
  4. Fixed

The “Fixed” setting l neutralizes the keyboard’s sensitivity and produces a level sound no matter how hard, or low a key is pressed.

The black keys have a matte finish and the white ones a glossy finish to prevent the slipping of fingers when wet from sweating after long sessions of playing the piano. The Graded Hammer Standard action is also available on the Yamaha P-115 and the Yamaha P45 from Yamaha’s digital piano P-series.

Sound Quality

The DGX-660 uses a Pure C.F. Sound Engine that is the same source of sound for the P-255 and P-115. This Pure C.F. Sound Engine is utterly responsible for the sound recorded on the Yamaha CFIIIS Full Concert grand piano. The piano has also enabled room for creativity due to its many sounds. It has a total of 554 instruments. They include:

  • 10 piano sounds such as the Live, Natural, Warm Grand, Pop Grand, and more.
  • 14 Guitars
  • 12 Electric pianos
  • 14 Saxophones
  • 5 Accordions
  • 14 Organs
  • 16 Strings
  • 9 Trumpets
  • 9 Bass Guitars

Drum kits, synths, flutes, brasses, and many more sounds have also been incorporated. There are 26 harmony types of effects responsible for a much better performance, 41 reverb types that act by simulating the acoustics of different environments, and 44 chorus types for giving a much more thicker, and richer sound capable of simulating timing variations and pitch in order to produce a sound that seems to be coming from several players performing at the same time.

The DGX-660 has a Pitch Bend wheel that will make it capable of producing various exciting sound effects. The polyphony reaches a maximum of 192 notes, and the speakers are 12cm x 2 plus 5cm x 2 built-in, with two 6W amplifiers. Intelligent Acoustic Control ensures the quality of the sound is improved by intelligently adjusting the treble and bass frequencies.

Connectivity

Unlike many digital pianos, the DGX-660 offers a lot more connectivity options. All of them may be found on the rear panel of the keyboard aside from the USB to the host terminal located on the front.

USB to Host terminal – This is useful in connecting the keyboard to a computer in aid of exchanging files/songs.

Headphone jack – The jack is ¼” and has multiple uses. It can be connected to a pair of headphones, and one can play without disturbing anyone. The other function is that it can also be connected as a Line Out to an external sound system such as a mixer, amplifier, etc.

USB to Device terminal – This is responsible for any Data/files sent to/from the keyboard by using a USB flash drive. That is, data produced in the piano may be saved to a disk. MIDI files may also be downloaded from the internet and played directly from a flash drive.

Aux in – It enables connectivity to external sound systems to the keyboard through a 1/8” mini-jack.

Pedal unit jack – There is an optional LP-7A/LP-7AWH can connect to this jack.

Sustain jack – A sustain pedal or footswitch can be connected to the keyboard using this jack.

Extra Features

The DGX 660 has all the necessary functions needed to provide an excellent experience. It includes extra features such as the transpose, an onboard metronome, tuning functions, Split Mode, Dual mode, and a 2-track MIDI recorder. The split mode is capable of playing two different instruments by dividing the piano into two sides.

Dual-mode ensures there is a layering of two different sounds on the keyboard so that they end up sounding at the same time. The piano is capable of working with two different types of data which are the MIDI and Audio.

MIDI is responsible for recording the actual sound of the instrument but in their lengths, the sequence of notes and velocity. Audio, on the other hand, records the actual sound of the keyboard, and the DGX-660 accepts up to 80 minutes of recording and stores it to a flash drive in W.A.V. format.

The audio recorded can be played in any of your smart devices. The piano also features a metronome which assists in improving the speed and timing accuracy of the player. The transpose and tuning functions may be applicable in adjusting the pitch of the keyboard.

Benefits of Yamaha DGX 660

If you are looking for the best cost-benefit digital piano, then you’re lucky because the DGX-660 has lots of benefits to offer its users. It is both suitable for beginners and seasoned pianists. As I had explained earlier, the Yamaha Educational Suite feature will go a long way in assisting both a beginner and even an experienced pianist. The DGX-660 has three types of lessons, namely; Your Tempo, Waiting, and Minus One.

Your Tempo – This is mostly about correct timing. The playback tempo adjusts to become level with your playing speed. The melody also adjusts itself if wrong notes end up being played and will only resume to the initial tempo when the correct notes are played.

Waiting – Here, the song waits until the correct notes are shown on the LCD screen are played before the playback resumes.

Minus One – In this lesson, the user can choose either the left or right-hand part of a song for practicing and play at a reasonable tempo besides the playback of the other hand part of the piano. The DGX-660 also displays music scores and lyrics of songs. There are also a lot of new beneficial features alongside advanced, already pre-existing features within the digital piano.
