Surround speakers should be placed on the side walls of the room, at or slightly behind the listening position. The speakers should be located so that the bottom of the cabinet is at least 24� higher than the listeners� ears when in the desired area. If side wall mounting is not practical, the speakers may be placed on a rear wall, behind the listening position. Again, they should be located so that the bottom of the cabinet is at least 24� higher than the listeners� ears. The speakers should be no more than 6� behind the rear of the seating area. Subwoofers produce non-directional sound, so they may be placed almost anywhere in a room. Subwoofer placement is highly influenced by room size and shape, and the type of subwoofer used. Follow the instructions of the subwoofer�s manufacturer, or experiment with the best location for a subwoofer in your listening room. Speaker Connections Once the speakers are positioned in the room connect them to the rear panel output terminals. For optimal reproduction we recommend the use of high quality speaker wire. Wire of AWG 16 or greater is recommended for short runs (under 15�) and wire of AWG 14 or greater is recommended for longer runs. Be certain to observe polarity when connecting speakers by connecting the positive (+) and negative (-) terminals on the AVR40 to like terminals on the speakers. To connect the front left, right and center channel speakers twist the red or black terminal ¤�� counterclockwise until the V-shaped notch at the rear of the terminal is exposed. Insert the

stripped end of the speaker wire through the notch and tighten the terminal until it is tight. NOTE: Be certain to match positive (+) terminals on the AVR40 to the positive terminals on the speakers. While most speaker manufacturers observe the same red/black color code as the AVR40, some reverse the pattern. IMPORTANT NOTE: To avoid a short circuit that will cause the receiver to shut down, make sure that the wires for one speaker do not touch any other. For proper operation, it is essential that a speaker be connected to BOTH Rear Speaker � terminals. If only one rear speaker is connected, no sound will be heard. It is also important that the impedance of the rear speakers be no less than 4-ohms each, although 6-ohm or 8-ohm speakers may also be used. To connect the rear speakers �, hold the spring clips down and push the wire through the hole, making certain that the inner copper conductors do not separate. Release the clip to secure the connection. Again, make certain that you observe proper polarity by connecting the (+) terminals on the receiver to (+) terminals on the speakers, and likewise for the negative (-) terminals. Subwoofer connections are made using the Subwoofer Outputs a. When using a powered subwoofer, connect BOTH the left and right output subwoofer outputs to the respective left and right line level inputs on your subwoofer. The AVR40 subwoofer outputs are full range, so it may be necessary to adjust the crossover frequency on the subwoofer�s control panel to properly match the subwoofer to your other speakers.
