WALL-MOUNTING THE PRIMUS 140 AND PRIMUS 150

The Primus 140 and Primus 150 are designed to mount directly to a wall. Each satellite speaker has two keyholes on the back. Each speaker will require (2) 1-1/2," #10 wood screws fastened to a wall stud. If a wall stud is unavailable, install an anchor appropriate for a 1-1/2," #10 screw.

NOTE: The customer is responsible for the correct selection and use of mounting hardware (available through hardware stores) that will ensure the proper and safe wall-mounting of the speakers.

Step 1.

Mark the positions on the wall where you would like to place the mounting screws.

Step 2.

Fasten two 1-1/2," #10 wood screws to the wall using the markings placed in Step 1 as your guide. Leave an 11/16" space between the wall and screwhead. If a wall stud is not available, use an appropriate anchor.

Step 3.

Place the speaker on the wall by aligning the keyholes on the back of the speaker to the screwheads on the wall. Once positioned properly, the speaker should slide down slightly and become secure.

The Primus 140 also allows the use of third-party wall brackets using the 1/4"-20 threaded insert located beneath the keyhole mount. Consult the wall-bracket manufacturer for selection of proper bracket.ker on the wall by aligning the keyhole on the back of the speaker to the screwhead on the wall. Once positioned properly, the speaker should slide down slightly and become secure.

WIRING THE SYSTEM

IMPORTANT: Make sure all equipment is turned off before making any connections.

For speaker connections, use a minimum #16-gauge speaker wire with polarity coding. The side of the wire with a ridge or other coding is usually considered positive polarity (i.e., +).

NOTE: If desired, consult your local Infinity dealer about speaker wire and connection options.

The speakers have coded terminals that accept a variety of wire connec- tors. The most common connection is shown in Figure 5.

To ensure proper polarity, connect each + terminal on the back of the amplifier or receiver to the respective + (red) terminal on each speaker, as shown in Figure 6. Connect the – (black) terminals in a similar way. See the owner’s guides that were included with your amplifier, receiver and television to confirm connection procedures.

IMPORTANT: Do not reverse polarities (i.e., + to – or – to +) when making connections. Doing so will cause poor imaging and diminished bass response.

Figure 5. This example shows how to connect bare wires to the terminals.
