Casio PX-160 Privia Touch Sensitive 88 Key Tri Sensor Scaled Hammer Action Keyboard Digital Piano with Stand, Pedal Board , Piano Lamp, Bench, Headphone, Instructional Book and Zorro Polishing Cloth The PX-160 utilizes Casios famous Tri-Sensor Scaled Hammer Action II keyboard. This action features new simulated Ebony and Ivory textured keys for an incredible feel and its three sensors capture the dynamics of a performance with unparalleled speed and accuracy. Casios proprietary Hammer Response feature takes into consideration the speed at which different sized hammers move inside an acoustic grand piano relative to the velocity the keys are played. Casios proprietary sound source, AiR (Acoustic and intelligent Resonator) provides the grand piano sounds in the PX-160. Casio meticulously recorded the sound of a 9-foot concert grand at 4 dynamic levels. The AiR engine delivers this sound with seamless dynamics for a remarkably expressive and powerful performance. Damper Resonance is simulated by AiR for uncanny realism when the damper pedal is used The chassis has been redesigned not only to provide a more elegant look but also to accommodate a new 8w x 8w speaker system, which delivers the PX-160s remarkable sounds with the richness that they deserve. This speaker system is open to the front but also ported to the back, which provides remarkable sound when the PX-160 is placed against a wall. This also allows it to easily be used in a classroom or other environment where the sound will be projected towards the audience. The PX-160 also features newly developed string ensemble sounds. These rich stereo strings sound wonderful by themselves or layered with the PX-160s grand pianos, electric pianos, harpsichord and more. The electric pianos have also been updated providing some dynamic sounds derived from Casios award winning PX-5S stage piano. The PX-160 provides split and layer capability allowing you to play bass in your left hand and have two layered tones in your right. For quiet listening, the PX-160 now has two headphone outputs which are located on the front of the instrument and for those who are performing with other amplification, the PX-160 also features 1/4" left and right line outputs on the rear panel. The PX-160 continues Casios tradition of providing class compliant USB connectivity on Privia digital pianos. This allows the PX-160 to be used with Mac or Windows computers without the need for downloading drivers.
