To Set-Up 2 Loudspeakers (Stereo)

Visual guide showing two speakers. One is designated as the MASTER, and the other as the SLAVE. Key controls and indicators are highlighted: PAIR BUTTON, LINK BUTTON, PAIR LED, and LINK LED.

  1. Choose one loudspeaker as the MASTER. The other will automatically become the SLAVE. Ensure only one is designated MASTER.
  2. Press and release the PAIR BUTTON on the MASTER loudspeaker. The PAIR LED will flash, and a tone will repeat approximately every second.
  3. On your Bluetooth audio device, select 'ALTO PRO WIRELESS'.
  4. Wait for the device to pair. This process may take up to 60 seconds or longer. Upon successful pairing, the tones will cease, and the PAIR LED will illuminate steadily. If the device fails to connect, repeat steps 2 and 3.
  5. Press and release the LINK BUTTON on the MASTER loudspeaker. The LINK LED will flash, and a repetitive tone sequence (beep beep) will be heard. If this does not function as expected, wait 5 seconds and press the button again.
  6. Press and release the LINK BUTTON on the SLAVE loudspeaker. The LINK LED will flash, and a repetitive tone sequence (beep beep) will be heard. If this does not function as expected, wait 5 seconds and press the button again.
  7. Wait for the MASTER and SLAVE loudspeakers to link. Successful linking is indicated when the tones stop and the LINK LEDs on both speakers light up solid. If they do not link within 2 minutes, power off both loudspeakers, then power them back on and resume from step 2.
  8. Play Music.
