Rena's LA Audio PC80 Phase Checker

A few days ago I ended up using the LA Audio Phase Checker to test the sound rig that gets used at MacEwan Hall at the University of Calgary. This thing is pretty cool.

Its a send and receive based system. The "emitter" sends a pulse through the whole PA and the "receiver" picks up the pulse after it leaves the speaker and instantly tells you if something is in or out of phase with either a green or red LED. You can also check phasing in hard wired situations with the built in XLR mounts whether its a reversed cable, or input, or anything that passes a balanced signal. Its a great feeling knowing that the speakers and components you are using in a rig are perfectly in phase. The kit also comes with a cable tester.

You can get all the details in the LA Audio's data

sheet HERE.

A big thank you to Rena Kozak for showing me this incredible tool. She is the House Audio Technical Co-ordinator at the University of Calgary. She had me in for a couple days of testing and repairing her frequently used sound system. We phase tested every speaker and component in the rig, and now we know that everything is working perfectly. On any given day you can expect Rena to be setting up her rig in either MacEwan Hall, or the smaller Ballroom upstairs. She uses a Meyer rig including 8 MSL-4's for the mains, 2 CQ-2's for audience fills, 4 UPJ-1P's for front fills, and 10 18" Sub cabinets (20 drivers). She has a Yamaha PM5D-RH at Front of House, and a Soundcraft SM16 for Monitors, currently being operated my Mike Rowland.

In picture to the left is Rena is displaying the LA PC80 in front of her pimped out, pink screened PM5D in MacEwan Hall. But don't let the pink fool you, she is a solid Sound Engineer with years of studio and live audio experience and training. She's taught me a lot during my stay in Calgary this month.

Thanks Rena!
