• Cut a squared hole in the wall to place the electrical box.
• Place the electrical box and fix it to the wall. Previously all cabling (speaker outputs, AC power and signal input) has been installed in the wall with sufficient length to provide proper stress relief.
• Run the cables out of the wall Through the electrical box.
• Attach the metal mounting ring to the electrical box with the provided screws.
• Mount the connectors on the extremes of the installed cabling.
• Connect the unit (speaker outputs, AC power etc.) and secure it to the mounting ring.

Use

All the main functions can be controlled using the front panel buttons. More options are available using the remote control. To switch on the unit, change the position (to the right) of the slide button located at the bottom. When using an external sound source (line input), be sure to switch on this unit before the amplifier. Once the amplifier has been switched on, select the au – dio source and start playing music. It is recommendable to start at low levels and increase volume if needed (the volume can be adjusted in 20 different levels). When setting the unit into standby mode (using the remote controller), it will restart by default reproducing the latest audio source before being switched off and keeping the same volume. When switching off the unit from the bottom button, it won´t keep the audio source previously selected. It will restart trying to find audio sources in this order:

• Micro SD
• BT
• USB

When connecting the unit via Bluetooth to a mobile device such a tablet or phone, the displayed name should be BA-225D. When the link between the tablet or phone and the amplifier has been set, no other devices can be paired to the unit unless the device has lost the link (because of the distance) or has been unpaired by the user.
