See the assembly drawings in Section 6 for component locations. Be sure to turn the
power off before removing or installing circuit boards.
Follow these instructions in order without skipping steps.
Note: All levels are the same regardless of whether the output is balanced or unbalanced.
To unbalance an output, connect either pin 2 or pin 3 of the XLR to pin 1 (ground). The
remaining pin is "hot."
All levels refer to balanced outputs. These readings are 6dB higher than unbalanced
readings. For unbalanced output, measure between pin 1 (ground) and pin 2 (hot).
Note: All analog output measurements must be taken with a 600Ω resistor tied between
pin 2 and 3.
1. Prepare the unit.
Use the front panel controls to set the 6200's software controls to their default set-
