Works with Alexa

MartinLogan DTS Play-Fi products now have “Works with Alexa” certification, meaning they can be controlled using voice commands given to an Amazon Echo, Echo Dot, Echo Show, Fire TV Cube, or other Alexa voice command-enabled device. Alexa functionality is activated by using the Alexa app to enable the DTS Play-Fi skill. This links your Alexa account to "Works with Alexa" DTS Play-Fi compatible products like this one.

After installing the skill, Alexa will know your speaker by name and allow you to control volume and playback functions such as track skip, mute, pause, and stop or request a song to play in a specific room or group of rooms linked together. Once an Alexa voice command is used to start audio playback, the DTS Play-Fi app can be used to dynamically add more products to the streaming session. Additionally, Alexa's Routines feature can be used to create events that initiate audio playback on your DTS Play-Fi speaker, such as setting up your speaker to work as an alarm clock by starting your favorite song.

MartinLogan Unison Wireless Preamplifier

"ML’s Unison preamp had the clarity I’ve come to expect from the best systems, and ARC seemed to me better than ever. Subtle details of instruments’ sounds were better integrated, my room’s midbass boom was gone, and the precision of the placement of instruments and voices on the soundstage was no longer limited by the room."

"I simply loved the MartinLogan Unison. It lets you convert virtually any analog or digital audio component into a multi-room audio node using your choice of DTS Play-Fi or Apple’s AirPlay. The inclusion of ARC is icing on the cake that enables the gear it’s connected to to deliver the best performance possible from the room that it’s in. The Unison is a no-brainer recommendation."
