A portable digital piano bundle with Bluetooth capabilities, power supply and a sustain pedal.

The Allegro IV digital piano from Williams provides the sound and feel of a real grand piano in a compact, Bluetooth-enabled instrument. With 12 different instrument sounds and a hammer-weighted keyboard, it offers an authentic playing experience for pianists of all levels. The Allegro IV is equipped with a powerful speaker system that produces full, realistic sound with an impressive bass response, allowing the nuances of your performance to shine through.

Grand Piano Sound and 12 Instrument Types

At the heart of the Allegro IV is a stereo grand piano sound recorded from a famous Italian concert grand piano. In addition to the robust grand piano sound, you have a choice of 11 other instrument types such as electric pianos, organs and synthesizers. You can layer or split different instrument sounds on the keyboard for a full, multi-textured performance.

Hammer-Weighted Keyboard Provides Realistic Feel

The Allegro IV's graded, hammer-weighted keyboard provides the feel of an acoustic piano, with heavier touch in the bass and lighter touch in the treble. This familiar, realistic feel allows for expressive control and nuanced playing. For an even more authentic grand piano experience, add the optional Williams wooden stand and triple pedal unit.

Powerful Speaker System Delivers Impressive Sound

The Allegro IV features a powerful speaker system rarely found in portable digital pianos. Large, ported speaker cabinets provide an extended bass response while dual drivers and a powerful amplifier generate full, realistic sound. Advanced DSP technology further enhances the sound with rich tone and clarity. Whether you're practicing with headphones or performing for others, the Allegro IV delivers high-quality sound with the full dynamic range of an acoustic grand piano.

Connectivity Options for Playing and Recording

With Bluetooth audio connectivity, you can wirelessly stream music through the Allegro IV's speaker system or headphones to play along. The built-in Bluetooth MIDI also allows you to use piano learning apps. An AUX input provides another option for connecting external audio devices. The USB audio/MIDI interface lets you connect to a computer for recording your performances or using digital audio workstations.
