On the UIW 55, 65 and 75, you will note that there is a two position switch marked HF EQ on the top of the crossover circuit board facing the speaker bafﬂe.

Step by Step Installation

The included template is the exact size of the required speaker opening. Once you have decided on a general location for your speaker, hold the template in the preferred position on the wall or ceiling and trace around it taking care that the opening is level.

Use a saw or knife to cut the opening.

Run color coded wires between the speaker cavity and the ampliﬁer unit. When running the wires inside the wall to the opening, leave a minimum of 12" of additional length in the cavity to facilitate speaker connection.

Connect the speaker wires to the In-Wall unit taking care to make red to red (“+”) and black to black (“-”) terminal connections.

Refer to your ampliﬁer or receiver loudspeaker wiring instructions, turn off the unit and connect the speaker wires to the appropriate col- ored output terminal on the unit, again making red to red (“+”)

and black to black (“-”) connections. This will ensure absolute phase throughout the system.

The metal pivoting dogs are pre-installed in the loudspeaker frame with Phillips screws. The dogs can be rotated left or right by turning the screws.

To install speaker, ﬁrst rotate screws one-half turn counter clock- wise to swing the dogs into position to clear the edge of the wall cutout. Then place speaker frame in position in the cutout and rotate screws clockwise one-half turn to grip the wall and tighten by hand until frame is stable but loose enough to be adjusted in ﬁnal position. Level the speaker frame and snug screws into place taking care not to overtighten.

Fit grill on frame.
