Night and day difference
I received my MSC1 from Sweetwater a little over a week ago. Setup was a breeze with my Windows 7 64 PC, but when it came time to calibrating the Room Correction Mode, that was a different story.
My setup is a pair of LSR2328P active monitors and the MSC1. My first few attempts kept giving me error code 3 messages, and being as I am familiar with home theater audio calibrations, I thought that maybe I should check the actual levels of the speakers with a dB meter to start off with. Low and behold with both LSRs set to full open on the input gain, one of the speakers was outputting more volume than the other.
Once I adjusted the output of the speakers to match, I proceeded with attempting a couple more calibrations and they failed. Since like I mentioned before that I am familiar with home theater calibration, and I have previously calibrated a few JBL Synthesis systems and remember them being much louder during the calibration tests. Remembering this made me decide to raise the input trim on the MSC1 so more test tone signal was going through the unit, and walla... the calibration succeeded!
The difference between RMC being engaged and disengaged is night and day. With the RMC engaged the low end spectrum of the LSR2328Ps are much more defined, and the separation is unbelievable!
Hopefully some of the information I am sharing helps others in their setup and calibration. I wish JBL would update the instructions (maybe make a video if their is not one already), as I wouldn't have not figured it out without my experiences with their Synthesis systems.
I am only giving it 4 stars because of the lack of online JBL support pertaining to the calibration process and such, but as far as the quality of the unit I received it would deserve 5 stars.
