[. . . ] LavryBlack Series Model AD10 Analog to Digital Converter Lavry Engineering, Inc. Box 4602 Rolling Bay, WA 98061 http://lavryengineering. com email: techsupport@lavryengineering. com Rev 1. 20 January 24, 2008 Quick Start Guide The AD10's front panel has 3 regions: (1) The Function setting region is used to display and edit the AD10 operational settings. (2) The Left Channel Meter region has a dual function 1. A level meter (bar graph display) for the AD10 Left channel. [. . . ] DIGITAL OUTPUTS: Connect the XLR AES/EBU and /or the Toslink optical output to the digital input of your destination(s). If your destination has an RCA connector, plug the included XLR to RCA adapter into the digital output (marked AES/SPDIF). AC POWER: The AD10 automatically adjusts to AC power inputs in the range of 90 to 264 Volts AC and line frequencies between 47 and 63 Hertz. There are no settings to change. 3 OPERATION: A. Overview The AD10 has a single User Interface Switch that allows all functions to be controlled from one place. Moving the switch up or down will either select or set the function. All Rate, Clock, Sound, Bit Depth and Gain Control functions are controlled by this switch. When powered on, the unit initializes for about 6 seconds. After initialization completes, the function lamps indicate the unit settings. Also, the Level and Gain meters will flash for about 6 seconds to indicate the Gain setting for each channel. The unit is ready for use when the meters stop flashing. Functions In normal operating mode, one LED will be lit for each function, indicating the setting for that function. While in editing mode, a flashing LED will indicate status and function during programming. To enter the Function Mode, press the switch DOWN and hold it in this position until a Function LED starts to flash. Either click the switch DOWN to select the next function (Sample Rate, Clock, Sound, or Bit Depth), or click the switch UP, to select the next available Setting within that function. Please Note- To move more than one step, the switch must be clicked repeatedly; holding the switch down (or up) will not result in the setting changing by more than one step. It will either only change one step, or if held long enough in the applicable direction, will change the mode. To exit Function editing mode, hold the switch DOWN until the LED stops flashing. Alternatively, wait for 6 second (leave the switch untouched) and the unit will automatically exit the editing mode. Gain In normal mode the Level Meter indicate signal from 0dB, or Full Scale, to -13dB digital level. In Gain Mode, this meter will allow you to set up to 13dB's of gain, with each channel being individually controlled. When in Gain Set mode, ignore the minus sign in front of each of the Level values on the meter scale; these values will indicate the amount of Gain you are setting. [. . . ] Pin 1 shield - Unbalanced analog: Pin 2 non-inverting, Pin 3 signal return, Pin 1 shield - Balanced analog TRS: Tip non-inverting, Ring inverting, Sleeve shield - Unbalanced analog TS: Tip non-inverting, Sleeve signal return and shield - Termination set to 75 Ohms for Word Clock or AES connections using standard 75 Ohm coaxial cable with BNC connectors. Termination can be set by user to 110 Ohms using internal jumper U11 for AES signals connected using 110 Ohm cable with a BNC adapter. ¼" BNC Digital Output Connections: XLR - Connect to AES inputs using standard 110 ohm XLR to XLR cables - Connect to coaxial SPDIF inputs using supplied XLR to RCA adapter and user supplied 75 Ohm RCA to RCA "SPDIF" cable or user supplied adapter cable. 75 Ohm coaxial cable length should be kept short if possible- less than 3 meters; 2 meters is better and 1 meter is best. Optical - Optical output connects to SPDIF optical inputs using standard Toslink interconnect. [. . . ]
