One thing I've done in similar situations is to use phase cancellation to set azimuth. Set levels, reverse the polarity of one channel, then sum the two channels into mono & adjust the azimuth until the 1kHz disappears. --Jeff Jeff Carroll, Mastering Engineer Bluefield Mastering, Inc. - Raleigh, NC USA 919.859.0102 Toll Free 877.847.2583 www.bluefieldmastering.com
