AMPLIFIER AND CONTROL PANEL INSTALLATION
The plate amp panel requires a cutout 2.75″ x 1.75″ (70 x 45 mm) with at least 2.625″ (67 mm) depth. Mount the plate to your right speaker cabinet, and connect the included output leads to the terminals of your speaker or crossover network, observing correct polarity.
The control panel requires a cutout approximately 2.6″ x 0.79″ with at least
1″ depth. The control panel is press-fit, and uses no mounting hardware.
Different materials will have various degrees of “give” or resistance to the
pressure fit of the panel. Therefore, you may wish to cut a test hole(s) in a
piece of scrap material to ensure a proper fit, and only cut the hole in your
finished cabinet once this has been determined.
Connect the control panel to the amp panel using the included leads, then
press the control panel into place.
CONNECTING YOUR SPEAKERS
With the power turned OFF, use high quality wire for the connection between the right and left speakers. For distances up to 10 feet, conventional 18AWG wire is acceptable. For longer runs, heavier wire should be used. For proper performance please observe correct polarity.
BLUETOOTH CONNECTION
Turn the power switch ON. The speaker will enter pairing mode, and the LED indicator will flash blue quickly. Open the Bluetooth menu on your device and select “LP40PA”. You will hear two beeps when pairing is complete, and the LED will remain solid blue.
AUX CONNECTION
Plug your device into the AUX jack on the right speaker using a 3.5 mm stereo
cable (not included). The LED indicator will light solid red to indicate AUX
connection.
PLEASE NOTE: for the best sound quality in Bluetooth or AUX mode, we
recommend that your device’s volume level be set no higher than 90%.
