The optimized output stage features even lower re-sidual distortion than the MR2, com-bined with an extended level range up to +18 dBu.Compensated output StageThe output level corresponds over a wide range of loads to the set output voltage based upon the output imped-ance of the generator. Possible maxi-mum limits when reaching the output current limit are clearly indicated.Measurement FunctionsSophisticated and unique technology continuously measures load imped-ance, balance and any phantom power voltage, providing a detailed view of the connected load for rapid fault find-ing.Cable testThe built-in cable tester verifies the proper 1:1 pin connection through any cable connected between the XLR output and the built-in XLR input. Alternatively an optional Cable Test Plug may be used for single ended installations.Store Preset ConfigurationsUp to 10 complete instrument con-figurations can be stored in the inter-nal flash memory and reloaded for re-petitive tasks. The saved settings may also be transferred to other Minirator MR-PRO instruments.User Wave Forms (*.WAV)A number of user test signals may be stored as uncompressed WAV-files in the MR-PRO memory. The selected file is seamlessly looped. Data exchange is simplified via the USB port.MR2 or MR-PRo? The Minirator is available as MR2 and MR-PRO.
