using lcvm-beamformer filter to project time-domain eeg data

i would like to use the filters generated by the lcmv-beamformer
algorithm to project my plain time-domain eeg data to the sources in the
brain. what puzzles me is that my eeg data in microvolts gets scaled by
10^6-10^7 after projection. what kind of unit is this? (if the data
still has one...). is this scaling reliable and constant over subjects?

thanks in advance for your help,
