Setup menu BEAM settings When "AUTO SETUP" in the "IntelliBeam" menu (☞p. 24) is used, recommended beam settings are automatically applied by this unit. "HORIZONTAL ANGLE", "BEAM TRAVEL LENGTH", "FOCAL LENGTH" (except "Center"), and "IMAGE LOCATION" settings, however, can later be fine-tuned. Surround sound channel output can also be modified from the "BEAM" menu. HORIZONTAL ANGLE Adjust the horizontal angle of sound beams for each channel using test tones. Adjust toward L (left) to move the direction of the output to the left and adjust toward R (right) to move it to the right. Beam angle BEAM TRAVEL LENGTH 2) Specify the distance that sound beams travel for each channel. The distance starts at this unit, ends at the listening position, and includes refraction off a wall. The audio delay is adjusted and sound from each channel arrives at the listening position simultaneously. Sub menu1): Front L, Front R, Center, Surround L, Surround R Control range: 0.3 m to 24.0 m (1.0 ft to 80.0 ft) Sub menu: Subwoofer Control range: 0.3 m to 15.0 m (default: 2.5 m) (1.0 ft to 50.0 ft (default: 8.5 ft)) The length of each arrow indicates the beam travel length. Angle to Angle to left right Sub menu1): Front L, Front R, Center. Surround L, Surround R Control range: L90° to R90° Left T key: Increase angle. S key: Decrease angle. Right S key: Increase angle. T key: Decrease angle. FOCAL LENGTH 3) Expand the optimal listening area (sweet spot). The illustration below shows how output from all channels is once concentrated in a focal point and then expanded from that point. Apply negative (-) values to broaden the sweet spot, or positive (+) values to narrow the sweet spot. Focal length Focal point Sweet spot We recommend using the default setting (-0.5 m or -1.5 ft) for "Center". Sub menu1): Front L, Front R, Surround L, Surround R Control range: -1.0 m to +13.0 m (-3.5 ft to +43.5 ft) Sub menu: Center Control range: -1.0 m to +13.0 m (default: -0.5 m) (-3.5 ft to +43.5 ft (default: -1.5 ft)) 1) y Channels that cannot be configured are displayed in grey as settings are specified as indicated in "Changing the audio output method for surround playback" (☞p. 36). 2) Note Configure this setting only when you have adjusted "HORIZONTAL ANGLE". 3) y "AUTO SETUP" (☞p. 24) automatically enables a range for optimal listening (sweet spot) that is broader than the width of this unit. 60 En
