Switching on and off the device

Once the power cable has been connected to the back of the tower (14), connect the plug to the socket and move the Power switch (13) to the ON position. From that moment on, you can turn it on or off by pressing the On/ Off button (6) on the top panel or on the remote control for 2 seconds.

Initial setup

Before using the speaker, you need to download the Multiroom Wi-Fi app to your device. If you have an Android device, download the app from Google Play. If you have an iOS device, you can get it from the App Store. With this app you can set up and manage all compatible Wi-Fi speakers.

Turn on the speaker and wait until setup mode is enabled (you will hear a confirmation message). If you do not hear this message, press and hold the Change Function (5) button for 2 seconds to enable it.

Open the app and select ?Add device? on the lower part of the screen to start the setup. If you have already added a speaker, you can add another one by pressing the + symbol at the top of the screen.

Select the model of your device from the drop-down menu and press ?Connect Speaker?. Access the Wi-Fi settings on your smartphone or tablet and connect to the speaker?s network. The network will be called Smart Speaker_XXXX. Once connected, return to the app to continue.

NOTE: If your device works with Android 7.0 or higher, you may receive a notification to enable the Wi-Fi connection at this point. If you do not accept it, the setup may fail.

Once the speaker has been detected, you have to choose the Wi-Fi network you want to connect to and enter the password. After pressing ?Continue?, the app will set up the device. It will display a message once the process has been completed.

After this, you only have to give your speaker a name and set up an Amazon account. To do this, log in with your Amazon username and password, and choose the language you want for your interactions with Alexa.

NOTE: This final step is optional. You will only need to do this if you want to interact with Alexa. The other device functions can be used without logging in to Amazon.

Amazon Alexa

Once the initial setup has been completed, you will be able to interact with Alexa by pressing the corresponding button on the top panel or remote control (8). Ask a question or make a request while the lights on the device top panel glow cyan . Alexa will answer you automatically once you've finished talking.

To customize your Amazon Alexa experience and add Skills to enjoy more options, you'll need the Amazon Alexa app for Android or iOS. You can also access it through your web browser:

Change function

Press the Change function button (5) to choose between the available functions. The colour of the LED indicator (1) shows the enabled mode.

In case that there are no units connected to the rear inputs (USB, MicroSD or 3.5 mm jack), the Change function button (5) switches between Wi-Fi and Bluetooth mode. In case that all inputs are being used, this button will switch from one to another in the following order:

sudo apt-get update
sudo apt-get install pulseaudio-dlna

Access your operating system's audio manager and select the Smart Speaker as audio output.


If you have several Energy Sistem Wi-Fi speakers, you can connect them all to the same network and create stereo sound systems or play music separately through each speaker. To do this, first set up all your speakers pressing the + symbol on the upper part of the Multiroom Wi-Fi app and follow the steps.

Once connected, press and hold the speaker's name and release it on the main device's name to create speaker groups and listen to your music simultaneously.

Important: The speaker's performance in Multiroom mode, as well as the number of speakers working at the same time, depends directly on the router, the distance to the access point, and the used transmitter. It is recommended to connect a maximum of 10 loudspeakers in synchronized mode to ensure proper operation.

Individual Multiroom Mode

This Multiroom mode is set by default. Each speaker plays music independently. You can control each of them using the app or interacting directly with the device. You will know that this play mode is active by looking the app. Each device will have one separate line.

Synchronized mode

This synchronized Multiroom mode enables to play the same song on all speakers at the same time. To set this playback mode, press and hold the name of the device you prefer and drag it to the speaker's name you want to connect it to. Wait a few seconds and you will see that both devices are synchronized. The synchronized tracks will appear on the app screen. This way, you will create groups comprising a main speaker and the rest of speakers.

You can assign a different channel to each speaker.

  • L = Left channel
  • R = Right channel
  • LR = Stereo

The synchronized mode remains active until it is disabled manually, so if you change the main speaker's playback mode pressing the Change function button (5), for instance, to Bluetooth mode, you will be able to stream the contents via Bluetooth to all synchronized speakers.

To enable the individual Multiroom Mode once again, you only have to select the synchronized secondary speaker and drag it out of the group. Wait a few seconds and the process to end the synchronized mode will be completed.

Bluetooth mode

To pair your tower with a Bluetooth device, press the Change function button (5) on the top panel or remote control until Bluetooth mode is selected. At this point, access the Bluetooth settings on your device and search for the Smart 7 Tower among the detected devices. Once selected, the connection will be established immediately and you will hear a sound that confirms that both devices have been paired correctly.

If you want to pair your tower with another Bluetooth device, press and hold the Change function button (5) for 2 seconds to enable sync mode.

Removable USB sticks and microSD cards

Your Smart Speaker 7 Tower allows you to play MP3, WAV, WMA, FLAC and M4A files from USB sticks and microSD cards of up to 128 GB with supported FAT/ FAT32 file system.

Plug the USB stick into the corresponding port or insert the microSD card into the corresponding slot. The device will switch automatically to USB or microSD mode to play the content of the inserted storage card or USB stick. If you turn off the device or remove any storage unit, the internal memory will save the moment when you paused playback. If you connect the same removable storage unit once again, playback will resume from the point at which it stopped.

To browse songs, press Next (4) and Back (3) on the top panel for 2 seconds or press the same buttons on the remote control once. Press Change folder (15) on the remote control or press and hold Change function (5) on the panel to browse a different folder. Press Select repeat mode (16) on the remote control or press and hold Play/ Pause (7) on the panel to change playback mode.

Playback mode

Press Select repeat mode (16) on the remote control or press and hold Play/ Pause (7) on the panel to select one of the 4 options below:

  • Repeat all: all songs stored on the internal memory are read in chronological order. This mode is enabled by default when turning on the device.
  • Repeat folder: the folder with the songs you are listening to will be repeated.
  • Repeat one: the song you are listening to will be repeated over and over again.
  • Random: random playback of all internal memory contents.

Auxiliary audio input

Your Smart Speaker 7 Tower features an Audio-in for 3.5 mm jack (12) which allows you to connect your music player using the provided 3.5 mm jack audio cable.

Once you plug the cable into this input, Line-in mode will be enabled automatically. You will be able to change function even if the cable is still connected. To pause or resume playback use the Play/ Pause button (7) on the panel or on the remote control.

Please take into account that you will have to use the external source device connected to your tower to control music playback (change track, pause or adjust volume).

Changing the language

You can change the speaker's language using the Multiroom Wi-Fi app. Access the speaker's settings pressing the Settings icon on the speaker's right upper corner:

Then, select "Speaker info" and the menu to select the speaker's language will appear. There are two languages available: English and Spanish.

Mimimum router requirements

In order for the speakers to work via Wi-Fi correctly, the router of your private network must fulfill the following requirements:

  • Use a 2.4 GHz Wi-Fi band. The Multiroom system is not compatible with 5 GHz Wi-Fi bands.
  • The selected network must use a WEP/WPA-PSK/WPA-PSK/WPA2-PSK/WAPI security protocol with WEP64/WEP128/TKIP/AES encryption.
  • The selected network must enable the SSID broadcast.

Considerations related to advanced router settings that can cause problems:

  • Assign static IP addresses.
  • Filter the connections by MAC adresses.
  • The router doesn't have access to the Internet. If you need to set up an access code from an Internet browser to access the Internet, it won't be possible to set up the speaker and connect to these type of routers.

Network environments with high levels of noise or a low performance level between router and speaker can result in mistakes that affect settings. Please verify that both the speaker and the router are not far away from each other and that the Wi-Fi channel is not overflowed.
