Switching on and off the device

Once the power cable has been connected to the back of your Tower (21), connect the plug to the socket and move the power switch (20) to the ON position. From that moment on, you can turn it on or off by pressing the On/ Off button (7) on the top panel or on the remote control for 2 seconds.

Change function

In order to select different functions, press Change function (9). You will be able to see the selected function on the Display (1).

In case that there are no units connected to the rear inputs ('USB', 'MicroSD', 'AUX 1' or 'AUX 2'), the Change function (9) button will switch between Bluetooth, AUX1 or Radio FM.

In case that all inputs are being used, the Change function (9) will switch from one to another in the following order:

Bluetooth -> USB -> microSD -> AUX2 -> AUX1 -> FM Radio

Bluetooth connection

To pair your tower with a Bluetooth device, press the Change function button (9) on the top panel or remote control until "bt" is displayed on the LED display (1). At this point, access the Bluetooth settings on the device and search for the Tower 7 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 (9) for 2 seconds to enable sync mode.

True Wireless Stereo

This technology allows you to wirelessly connect another True Wireless Stereo device within a maximum distance range of 10 meters to increase power and create a stereo system with separate left and right channels.

Switch on both devices and enable Bluetooth mode, press the TWS Connection button (10) on each device and you will see that the L/R indicators blink alternately on the LED display (1). Once the connection has been established, you will hear a confirmation sound and the L/R indicators will stop blinking. From that moment on, both devices will play the same content simultaneously.

Press and hold once again the TWS Connection (10) button a few seconds to disable TWS connection.

Removable USB sticks and microSD cards

Your Tower 7 True Wireless allows you to play MP3 and WAV files from USB sticks and microSD cards of up to 128 GB (FAT, FAT32 y exFAT).

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 (5) and Back (3) on the panel or the same buttons on the remote control. Press and hold the above mentioned buttons to fast-forward and rewind and get to the part you want to hear.

Press Change folder (22) on the remote control or press and hold Change function (9) on the panel to browse through a different folder. Please keep in mind that you can change playback mode by pressing Select repeat mode (24) on the remote control or by pressing and holding Play/ Pause (4) on the panel.

Playback mode

Press Select repeat mode (24) on the remote control or press and hold Play/ Pause (4) on the panel to select one of the 4 options below:

1) ALL: all USB or card contents will be repeated. The folders and files of your external cards or sticks will be read in chronological order.

2) ONE: the song you are listening to will be repeated.

2) FOLDER: the folder with the songs you are listening to will be repeated.

4) RANDOM: random playback of all the contents of your removable storage unit.

Mini jack and RCA inputs (analogue inputs)

Your Tower 7 True Wireless features two analogue stereo inputs to connect external devices. The first one is a mini jack input (the cable is provided with the product) and the other one is a RCA audio-in.

Mini jack input

Your Tower 7 True Wireless features an 3.5 mm audio-in (AUX) (16) which allows you to connect your music player using a 3.5 mm jack audio cable.

Once you connect the cable to this input, "Line-in" mode will be enabled automatically and you will see the word "AUX2" on the Display (1). You will be able to change function even if the cable is still connected.

To pause or resume playback use the Play/ Pause (4) button on the panel or on the remote control.

We recommend to use this input to connect small devices such as MP3 players or smartphones.

RCA input

This audio-in is situated on the rear top part with the name "INPUT". It has been conceived to connect your TV or audio devices permanently.

Press the Change function (9) button to enable and disable the use of this input.

We recommend to use this input to connect audio systems such as stack systems, televisions or mixing desks permanently.

Important: In both cases, you will have to control music playback (volume, equalizer or track changes) using the external music player connected to your tower.

FM radio

To be able to use this function, you have to tune in the radio stations first. To do that, connect the radio antenna on the rear top panel and press and hold the Change function (9) button on the top panel for two seconds while radio mode is enabled. The process may take a few minutes.

The radio stations will be saved to the memory of your Tower 7 True Wireless, therefore it is not necessary to carry out a new search each time you switch it on. You will only have to do this when you place the tower in a new location. Press Back (3) or Next (5)* once again to switch from one saved station to another.

You can use either the antenna provided with the product or connect the tower to the antenna outlet on the wall of your house using a RF coaxial IEC male to female cable. You will get better signal this way.

RCA audio-out (analogue output)

Your Tower 7 True Wireless features a RCA audio-out (AUX) (11) to connect other self-powered speakers featuring an analogue input and hear your music simultaneously through several speakers.

You can even connect a second Tower 7 True Wireless to your tower using a RCA male to RCA male stereo cable. To do that, connect one end of the cable to the OUTPUT of the first tower and the other end to the INPUT of the second tower. The signal will be transferred to the second tower, regardless of the enabled playback mode and music both devices will play music simultaneously.

This analogue output makes it possible to create a sound stereo system for your tv by connecting both Tower as follows:

Schema

To set up the system, you will need two RCA splitter cables (male to male).

USB port to charge external devices

Your Tower 7 True Wireless features an USB charging port (13) to connect an USB cable and charge other devices such as smartphones, tablets or MP3 players, even while playing music.

Output technical specifications:

  • Voltage = 5 V
  • Current = 2 A

Any device that requires more than 5 V voltage cannot be charged.

Important: In case you are using the provided radio antenna, keep it away from the charging cable to avoid interferences while charging devices.

The device has two controllers at the back that enable users to adjust equalization:

  • Adjust Treble (This function is indicated as "Treble")
  • Adjust Bass (This function is indicated as "Bass")
