System Installation
1.Unpacking Your System
•Ensure that you have received all of the components to your system.
•Locate the speaker installation instruction sheet that is packed with your speakers.
•Keep ALL packaging materials. If the system must be returned, it will be quick, convenient and undamaged.
2.Location
Before installing the system, take time to consider the placement of your components.
•Infrared (IR) Sensor: Consider areas of dark color in the room as they reflect less infrared light. Sensor mounting locations should be closer to dark areas to improve reception.
•Receiver: Place on flat surface close to standard electrical outlet.
•Speaker: Refer to the speaker installation sheet that is included with the speaker for placement needs.
•Speaker Wire and Sensor Wire: Plenum wire is included for each. Ensure the wire length will cover the area from where you hang the sensor and speaker(s) to where you place the receiver. It’s optimal to route wire overhead (above ceiling tiles) if possible. In addition, wire can be routed down the wall and around the room perimeter secured with heavy staples or wire raceway.
3.Speaker(s)
•Locate the speaker installation instructions packed with your speaker(s).
•Follow instructions and mount speakers(s).
•Return to the LES 780iR manual to complete the set up of your system.
4.Receiver/Amplifier
•Place the LES 780iR on a flat surface like a bookcase or countertop.
•Ensure that the A VOLUME and B VOLUME knobs are turned all the way down (fully
•Connect the speaker wire(s) to the appropriate 1/4” SPEAKER OUT jacks on the back of the LES 780iR. (Refer to your speaker instructions for additional information.)
•Plug the power cord into a standard 110 V electrical outlet and attach the other end into the DC POWER jack on the back of the LES 780iR.
•Switch the power on the front panel to the ON position. The red power indicator on the switch will light.
