With the new v 1.11 software for TC TouchMonitor TM7 & TM9, you can load two LM6 Radar instances simultaneously for dual 24-hour history, which allows you to monitor both a pre and a post processing signal at the same time. You could also set up your TM7 or TM9 to display a stereo Radar and a 5.1 Radar simultaneously - or two stereo or two 5.1 Radars for that matter!
