Overview
Ultra AL32 Processing utilizes data interpolation algorithms and supports high-resolution 192-kHz/24-bit PCM signal input. These algorithms interpolate points that should exist before and after the points in large quantities of data to achieve a smooth waveform that is close to that of the original signal.

Carefully restoring data that was lost during digital recording results in playback sound that is highly detailed, richly expressive in the lower range, and beautifully faithful to the original sound.

Because accuracy is the key to performance, the high-quality master clock is the reference for the four-audio DAC operation, the network module, and USB-DAC to ensure that the digital audio circuitry performs at its maximum potential.

With HEOS Built-in technology, enjoy your favorite music in any room of your home for a wireless, whole-home audio experience. Play the same song in every room or select a different song for each connected room—the choice is yours. Enjoy streaming music from your favorite music service or your local music file libraries. With additional HEOS Built-in components, like HEOS-capable speakers, play all your music in one room or many.

Use your voice to stream your favourite music services via Alexa. Ask Alexa to play music, turn volume up or down, pause, mute, and play the next song—all with your voice. To start streaming with Alexa voice commands, open the Alexa app, select “Skills,” and add HEOS Home Entertainment. Then, go to Smart Home in the Alexa app menu and choose “Devices and Discover” or say, “Alexa, discover my devices.”

Stream audio from your favourite music services like Apple Music and Spotify from any iPhone, iPad, Mac, or Apple TV. Hear audio perfectly synced to your speakers from AirPlay 2 sources. Use AirPlay 2 in-app or with your voice via Siri.

The center button is play/pause/enter. It determines selection and acts as play/pause on the “Now Playing” screen. Surrounding buttons are directional cursors: up, down, right, left. Left and right buttons work as previous and next, respectively, on the “Now Playing” screen.
