1. Locate the USB port

Find the USB port on your speaker. It is usually located on the side or at the back of the device.

2. Insert the USB key

Gently insert your USB key into the designated port. Make sure it is securely in place without forcing it.

3. Turn on the speaker

If not already done, power on the speaker by pressing the power button.

4. Select USB mode

Use the mode button on the speaker to switch to USB mode. This may be a dedicated button or a combination of buttons depending on the model.

5. Play music

Once in USB mode, the speaker will automatically detect the audio files on the key. You can then use the play, pause, and navigation controls to listen to your music.

Note: Ensure that the audio files on the USB key are in a format compatible with the speaker (e.g., MP3, WAV).

How to connect two BOOST 120VHF-BT speakers together?

Accepted Answer

The BOOST 120VHF-BT has several options for simultaneously playing sound on two speakers, depending on your setup and needs.

Wired connection (recommended method) - This is the best approach to connect two BOOST 120VHF-BT speakers. Plug an audio cable from the MIX OUT (output to mixer or amplifier) of the first speaker into the LINE IN (RCA connector) of the second speaker. The first speaker receives the audio signal from your source and then transmits the signal to the second speaker via this wired connection. This setup allows simultaneous sound playback on both devices. You can connect your audio source (smartphone via Bluetooth, USB stick, SD card, or other device) to the first speaker, and the signal will automatically propagate to the second speaker.

Wireless streaming via separate Bluetooth - If you prefer a cable-free setup, you can activate the Bluetooth function on each of the two speakers and pair them separately with your mobile device or computer. To activate Bluetooth: press the Bluetooth control button (button 23), wait for the LED (22) to light up, then hold the pairing button for 3 seconds until the LED blinks. Once both speakers are paired with your device, enable the simultaneous playback option on multiple speakers in your device's Bluetooth settings (if available). Note that this method does not create true stereo (left/right) but streams the same signal to both speakers.

Practical tips - For better sound quality with the wired connection, keep the two speakers close to each other (at least 5 meters apart) and use high-quality audio cables to avoid interference. Ensure that the RCA cables are firmly connected to the correct jacks (red/white for stereo). Before connecting, make sure both speakers are turned off, then turn them on after making the connections to avoid damage.
