Features

Made for iPod iPhone iPad

The “Made for iPod/iPhone/iPad logo means the Onkyo product was designed specifically to interface with these Apple devices. This compatibility allows the user to control playback using the Onkyo system remote controller while their iPod, iPhone, or iPad is recharged. Users can also enjoy superior sound quality, as signals are transported in digital form—rather than analog—via the direct-digital connection on selected models.
