Positioning speakers Speaker placement plays an important role in the reproduction of Surround sound. The manner in which the speakers are placed varies depending on the size of the room and the wall coverings used in the room. The illustration below shows an example of a layout for standard speaker placement. Refer to this example when you position the speakers in order to experience the best of Surround sound. Standard speaker placement TV or Screen Sub- Center ke woofer speaker speaker Surround speaker Left Listener Front sR'°i.gahkter Surround speaker Right For ideal Surround effects, all speakers should be installed. If a center speaker or subwoofer is not connected, the sound from the unused channel is properly distributed to the connected speakers in order to produce the best Surround sound possible. Front: The left, right. and center speakers should face the seated listener and be placed at ear level. The center speaker produces a richer sound image by enhancing the perception of the sound's source and movement. Surround: Place the left and right Surround speakers I meter (3 feet) above the listener's ear level and toward the sides of the room, making sure that the listener is within the speakers' dispersion angle. These speakers produce the feel of a moving sound while creating the sensation of being in the middle of the action. Subwoofer: Install a subwoofer with a built-in power amplifier for powerful bass sounds. The placement of the subwoofer does not affect the fi nal quality of the sound image too much, so you can install it with the room layout in mind. Refer to the speaker's instruction manual for more details.

With such amplifiers. you can play sources at even higher volume levels than with the TX-DS-747 alone.
