Nov.2002 fig.test71_70 fig.test81_70 Press the [F6] button to proceed to the [DIRECT OUTPUT 1 L/R] jack circuit test. First you will make the “5 cm” setting for the [D BEAM 1] controller. The LCD display will show “L-Low (5cm).” Use audio cables to connect the [DIRECT OUTPUT 1 L] jack to the [INPUT L] jack, and the [DIRECT OUTPUT 1 R] jack to the [INPUT R] jack. Then turn the [VOLUME INPUT] knob all the way to the right (MAX). Place your hand parallel with the panel surface at a vertical distance of 5 cm from the [D BEAM 1] controller, and press the [ENTER] button. Verify that the LCD display shows a sawtooth wave above and a sine wave below.
Do not move your hand as long as the lower part of the LCD display indicates “Now Adjusting....” When the setting is completed, you will automatically proceed to the next setting. Press the [F6] button to proceed to the [DIRECT OUTPUT 2 L/R] jack circuit test. Make the “5 cm” setting for the [D BEAM 2] controller. Use audio cables to connect the [DIRECT OUTPUT 2 L] jack to the [INPUT L] jack, and the [DIRECT OUTPUT 2 R] jack to the [INPUT R] jack. Then turn the [VOLUME INPUT] knob all the way to the right (MAX). Place your hand parallel with the panel surface at a vertical distance of 5 cm from the [D BEAM 2] controller, and press the [ENTER] button.
The LCD display will show “R-Low (5cm).” Verify that the LCD display shows a sawtooth wave above and a sine wave below. Do not move your hand as long as the lower part of the LCD display indicates “Now Adjusting....” Press the [F6] button to proceed to the [DIGITAL AUDIO INTERFACE OPTICAL] jack circuit test. When the setting is completed, you will automatically proceed to the next setting. Use an optical (angular plug) cable to connect the [DIGITAL AUDIO INTERFACE OPTICAL OUT] jack to the [DIGITAL AUDIO INTERFACE OPTICAL IN] jack. Make the “45 cm” setting for the [D BEAM 1] controller.
Place your hand parallel with the panel surface at a vertical distance of 45 cm from the [D BEAM 1] controller, and press the [ENTER] button. The LCD display will show “L-High (45cm).” Verify that the LCD display shows a sawtooth wave above and a sine wave below. Do not move your hand as long as the lower part of the LCD display indicates “Now Adjusting....” Press the [F6] button to proceed to the [DIGITAL AUDIO INTERFACE COAXIAL] jack circuit test. Use a coaxial (pin plug) cable to connect the [DIGITAL AUDIO INTERFACE COAXIAL OUT] jack to the [DIGITAL AUDIO INTERFACE COAXIAL IN] jack. When the setting is completed, you will automatically proceed to the next setting.
Verify that the LCD display shows a sawtooth wave above and a sine wave below. Make the “45 cm” setting for the [D BEAM 2] controller. The LCD display will show “R-High (45cm).” Press the [F6] button to proceed to the next test item. Place your hand parallel with the panel surface at a vertical distance of 45 cm from the [D BEAM 2] controller, and press the [ENTER] button. Do not move your hand as long as the lower part of the LCD display indicates “Now Adjusting....” 8. D-Beam Adjustment test When the setting is completed, you will automatically proceed to the next test item. This adjusts the sensitivity of the [TWIN D BEAM] controllers.
This adjustment will optimize the sensitivity of the controller at two distances (5 cm, 45 cm) from the [TWIN D BEAM] controller to the user’s hand. Here you will also correct any differences in the sensitivity of [D BEAM 1] and [D BEAM 2]. 9. D-Beam test This tests the operation of the [TWIN D BEAM] controllers. Before the test: In order to perform the D-Beam Adjustment test and the D- Beam test, the surroundings of the MC-909 must meet the following conditions. When you enter the D-Beam test, the LCD display will show as follows. • Do not place any objects near the MC-909.
(Keep them at least 30 cm away.) • Place the MC-909 at a distance (at least 100 cm) from large flat surfaces such as the walls or ceiling. • Do not place the MC-909 where strong light (such as direct sunlight or electric light) falls on it. When you enter the D-Beam Adjustment test, the LCD display will show the following. 26
