The two switches under the SELECT legend are used to change settings. moves the cursor left or right as indicated by the arrows. [. . . ] - If the outputs are configured for balanced operation and connected to unbalanced wiring, the reproduced audio will be significantly more distorted than with the proper configuration. - If the outputs are set for the unbalanced configuration opposite the correct one, there will be no audio reproduced. - The configuration of the XLR outputs has no affect on the headphone outputs. One way to confirm that the unbalanced setting is opposite the correct configuration is to check for the presence of audio in the headphones when there is no audio from the XLR outputs is. An example of incorrect setting with XLR to RCA adapters is if the outputs are configured for Pin 3 Hot instead of Pin 2 Hot. When in the Setting mode, the LED's above each label indicate the status of each setting. Please remember that the cursor position affects the way an LED indicates the status: - At the cursor position, a rapidly blinking LED indicates "on" and slowly blinking cursor indicates "off. " - At all other positions, a steadily illuminated LED indicates "on, " and an LED that is not illuminated indicates "off. " To set the XLR outputs; " down. 1. ) Enter the Setting mode by clicking the switch marked " 2. ) The current setting of the XLR outputs is now displayed above the front panel designations "pin 2" and "pin 3. " If it has not been changed from the factory setting, both LED's above the pin 2 and pin 3 designations will be "On, " denoting balanced operation. switch to move the flashing cursor until it is the above "pin 3" legend. Click the 3. ) Click the second switch down once in the set direction to toggle pin 3 "Off. " The LED above pin 3 will be "Off" to indicate that pin 3 of the XLR outputs is now connected to ground. This chart shows the status of the front panel LED's in Setting mode and the signals on the XLR output pins with the (audio polarity) invert function set to "off. " The "+" denotes non-inverted signal polarity and the "-"denotes inverted signal polarity. Setting for the XLR to RCA adapters included with the DA11 XLR Output Configuration LED status Pin 2 Signal Pin 3 Signal Balanced operation pin 2 "on" pin 3 "on" Audio + Audio Unbalanced Pin 2 Hot pin 2 "on" pin 3 "off" Audio + Ground Unbalanced Pin 3 Hot pin 2 "off" pin 3 "on" Ground Audio - * *For "Unbalanced Pin 3 Hot" operation, the invert function would normally need to be turned "on" to make the polarity of pin 3 "non-inverted. " Please see the "invert" section (below) for details on the signal polarity. 9 DA11 Operation OPERATION: A. FRONT PANEL DISPLAYS There are two modes for the front panel controls of the DA11- Operating Mode and Setting Mode. The front panel displays serve different functions in the two modes, and may also change appearance in each mode to indicate changes in settings or input signals. In the center of the front panel, the IMAGE display has three modes: - In Operating mode, two LED's indicate the setting of the >PiC< Playback Image ControlTM. The numbers above the display are the legend for this mode. - In Setting mode the status of all of the programmable settings are displayed. The legend for the indicators in Setting mode is below the display- xlr, opt, usb, rca, output, pin 2, pin 3, dim. - In Operating mode, if the "mute" function is activated by the optional infrared remote, the entire display goes "dark. " - In Operating mode, if the SAFE MODE of the infrared receiver is disabled, the two LED's that indicate the setting of the Stereo Image Control flash when the "LE" symbol appears. On the right side of the front panel, the VOLUME display has a number of modes: - Any time the VOLUME display reverts from the numerical display to the LE symbol, the settings are stored in non-volatile memory. - In Operating mode, the numerical value of the volume is displayed for ten seconds after the setting has been changed. After ten seconds, the "LE" symbol appears. [. . . ] - When SAFE MODE is disabled, the LED's in the IMAGE section will blink once whenever the VOLUME display reverts to the "LE" symbol. - The setting for SAFE MODE is stored in non-volatile memory, so the DA11 will retain the setting when the AC power is cycled. SPECIFICATIONS: THD+N at max volume (volume = 55) ­ typical, 0. 0008% FS, maximum 0. 0013% FS Test conditions: 20Hz ­ 20KHz, -3dBFS sine wave, 22-22KHz BW At all possible settings and switch combinations. This also applies to operating the DA11 with the included XLR to RCA adapters. Dynamic Range: -112dB typical, -110 dB minimum Test conditions: Non weighted At all possible settings and switch combinations. [. . . ]
