      To play audio files from a USB flash drive or hard drive

      • Connect the USB drive to the USB A input on the I15 Prisma MK2.
      • Use the Prisma app to browse, play, and control the music.

      The USB drive can contain folders and music files in any of the popular formats; see Technical specification for details.

      Note that playing music via the USB A input has the following restrictions:

      • No playlist.
      • No queue.
      • No album art.
      • The recommended arrangement for folders is alphabetical by artist folder.

      The USB input is mainly for USB thumb and other portable hard drives and has been tested up to 2TB drives on NTFS and FAT32. Please note exFAT is not supported.

      The USB A connection is recommended for less critical listening, as both signal and power go through this connection point, which we find subtly compromises performance when compared to a network connected hard drive.

      6.7. Streaming music from a phone, tablet, or PC

      The I15 Prisma MK2 can use Chromecast built-in to connect directly to a music service that supports Chromecast, such as Qobuz, Deezer, Tidal, TuneIn Radio and more. The music is streamed direct to the I15 Prisma MK2; once set up you can use your phone to make calls, or play other audio.

      With a phone, tablet, or Mac/PC you can also play the audio wirelessly to the I15 Prisma MK2, using Bluetooth or AirPlay (iOS only), so the sound from any apps you run on your device will be played through the I15 Prisma MK2.

      Although you can stream music over Wi-Fi, for best results connect the I15 Prisma MK2 to your home router via an Ethernet cable. If necessary, use the Google Home app to configure the network settings on your I15 Prisma MK2.

      To stream using Chromecast built-in

      The I15 Prisma MK2 has Chromecast built-in, which means you can stream (cast) music over your network directly to the I15 Prisma MK2 from any Chromecast supported music service, using the music service’s app on your desktop or mobile device as a controller. To be able to use Chromecast, please see Getting started and how to configure I15 Prisma MK2 with Google Home app.

      Click the Cast button within your music service’s app and select the I15 Prisma MK2 in the device list.

      To stream using AirPlay
