Manuals and Documentation
  • The speaker supports dual band 802.11 a/b/g/n/ac WIFI and Bluetooth 4.1 with BLE.

  • Download the Google Home application and then proceed to follow the prompts within the application.
    Further instructions can be found here:

  • To switch WiFi networks, open the Google Home app and tap on the Settings icon for the speaker you wish to change the network for. Select "Forget this Network" and then connect the speaker to a new network following the same prompts during the initial setup.

  • There is no need to turn your speaker on or off. When connected to a power source the speaker is always ready for use.

  • iOS and Android devices with the latest software updates can be used with your speaker. Unless you're using Bluetooth, the device must be connected to the same wireless network as the speaker.

  • The speaker is compatible with all Chromecast enabled streaming services. For a full list, please visit:

  • Once the speaker is connected to the wireless network, make sure the light next to CAST on the control panel is lit and then open your favorite music streaming app. Tap the Cast button and then Play.

  • To complete a factory reset, hold the -VOL and SOURCE keys for four seconds until the lights on the SOURCE key flash quickly four times.

  • When connected to a WiFI network, your speaker will automatically update with improved software when available.

  • Every speaker has a TOSLINK Optical and Auxiliary Analog 3.5mm input, both of which are compatible with devices that have similar outputs.

  • The unique serial number can be found the base of the packaging or the speaker base.

  • To create a stereo pair between two MA770 speakers, first make sure they are both connected to the same WiFi network. Now hold down the -VOL and PAUSE keys on the left speaker for four seconds. Once the lights on the SOURCE key quickly flash quickly release the keys. Next, hold down the +VOL and PAUSE keys on the right speaker for four seconds. Similarly, once the lights on the SOURCE key flash, you can release. When the lights on each speaker remain on, you've successfully created a stereo pair. If the pairing has failed, the lights on each speaker will quickly flash and then turn off.

  • To return your speakers to single unit mode, hold down the PAUSE key on either speaker for four seconds until the lights on the SOURCE key quickly flash. The lights flashing indicate the stereo pair has been disconnected.

  • An audio group can be created with multiple Chromecast Built-In enabled audio devices in separate rooms within a single location. To create an audio group via Chromecast Built-In, visit the Google Support Center for further instructions:

  • First make the light next to BT on the control panel is lit. Next, make sure Bluetooth is turned enabled on your mobile device and then select the speaker as the device. Tap Play within the music streaming application.

  • Each speaker has an Auxiliary Analog Audio and TOSLINK Optical Audio input. Your speaker is compatible with devices that have similar auxiliary and optical outputs.

  • The speaker can be cleaned with a lint free damp cloth. Only a minimal amount of water should be used to dampen the cloth; avoid all solvents. When handling the speaker, use both hands - one hand at the base and the second hand at the top corner of the opposite side.
