Re: Noisy A&H GL2400
Wow lots of great ideas here I'll try to answer some questions...
In Video Land, we have a four robotic camera recording
system, blu-ray playback, a video conferencing
system, output to the
house Panny
projector, output to
lobby video monitors, and output to stream over the internet. While we do have a campus TV station, I don't think the connection is in my booth, I think it's off in the video guy's main lair on the other side of campus. I'm not a
vidiot and don't exactly know everything that is going on the other side of that wall.
The Audi has been rebooted.
I'll try to test individual outputs one at a time.
Chris I think you have it right. My understanding is that the two
DSP's share audio information back and forth and give or take whatever signal they need from the
network. It's sort of a shared two part brain. We were having problems originally because the video guys installed the second
DSP on switched
power. Everything would work fine, then the video guys would turn off their rack and go home and my audio would go crazy because my
DSP suddenly couldn't find it's friend. I think the only way to
disconnect video from the
system is to crawl in the back of a tiny rack and unplug inputs one at a time. I'll see what happens.
Not sure if this helps at all, but my video guy was complaining about lots of noise from my rack of
Shure ULX-P receivers. When you unmute the Shures the noise goes up into like the 60db range. There is a single Senny 300 G2 in the rack and it sounds clean. We stopped using the Shures for video and the video guy brings over some AT 3000's instead which we just set up as needed and they sound clean. It all seams really odd that there is so much noise as those ULX-P's are good quality and cost more than the AT 3000's. The Shures were plugged into the same
circuit that the GL2400 is currently plugged into.
Should I try running the board through a
UPS to clean the
power?
EDIT: Just thinking that the GL2400, the rack of ULX-P's, the Audia EXPI (A/D converter), a computer for running SFX, a set of powered booth monitor speakers, and a CD burner all are plugged into the same Tripp Lite surge supressor. The problem could easily be that the power just isn't clean on that circut. Right? They really should be running through a line conditioner shouldn't they? Would one good UPS clean the electricity enough to fix any problems?
Pluss I need to install all ETC Sensor Sinewave dimmers to make Derek happy.
