In-wall Speaker Installation

To install a Performance Series in-wall speaker, proceed as described in the following paragraphs and accompanying diagrams:

Having selected the installation position and checked for the presence of studs (joists), pipe work, ducts or cables, mark a portrait orientation cut-line on the wall using the supplied template. Check that the dimensions of the cut-line are correct: 175 x 275 mm (678 x 1078 in) for the P4-W65, 215 x 370 mm (812 x 1412 in) for the P4-W80 and 175 x 340 mm (678 x 1338 in) for the P4-LCR50.

Use an appropriate tool to cut along the cut-line to create a cut-out in the wall. Trial fit the Speaker Unit in the cut-out to check clearances.

The length of free cable should be sufficient to allow the Speaker Unit to be held in one hand while connecting the cable to the terminals with the other hand.

The speaker cable can now be connected to the Speaker Unit. Strip 15 mm insulation from the cable (if necessary), twist the wire strands and insert the stripped ends into the Speaker Unit spring terminals. Ensure that the positive conductor is connected to the red speaker terminal and the negative conductor is connected to the black speaker terminal.

With the cut-out checked, and the cable connected the speaker can be installed. Insert the Speaker Unit into place and while holding it against the wall with one hand use the other hand to turn the four cross-head screws clockwise untill they are tight. Do not over-tighten the screws. Turning the screws first rotates the four internal securing clamps and then moves them inwards to secure the Speaker Unit against the inner surface of the drywall (plasterboard).

The high frequency tonal balance of the Performance Series speakers can be adjusted to suit different installation environments. A tweeter level switch located on the Speaker Unit front bezel offers +3 dB, 0 dB and -3 dB options. The level adjustment operates from approximately 3 kHz upwards.

With the speaker connected and secured into the Installation Frame, in-wall speaker installation is completed by fitting the grille. The grille is secured magnetically and requires no more than placing into position.
