Everyone, In preparation for an upcoming FOH article on generators, I've be reviewing the NEC and OSHA code, especially as it relates to GFCIs. The requisite "I am not an electrician" disclaimer here. --- GFCI and OSHA As it stands today, here is OSHA's stance:1926.404(b)(1)(ii) Ground-fault...

Everyone, The FOH magazine editors have asked me to write about generators. I agreed, as long as they put the world's biggest "I am not an electrician" disclaimer in front of the article. As a result, I'm trying to make sure all my ducks are in a row. Because inverter generators are an odd...

Folks, For an upcoming FOH article I'd like to solicit photos of "in the field" subwoofer configurations. Preferably configurations that you implemented at live event, and not for a permanent installation. I'm not looking exclusively for fancy (e.g. endfire) arrays, but also circumstances...

Curious, as the season ramps up, what's the componentry complement of your most common utility speaker. The one that serves as delays, front fills, SOS, monitor duty, etc. For instance, in my undergraduate days this would have been EAW JF:

Hey all, Let me first say that this isn't a backhanded launch of something sitting in the proverbial basement, I've done no formal development outside of my head yet. I learned my lesson from a year ago when I considered writing short audio instructional pamphlets for sale, and have since...

Hey All, Has anyone ever stumbled across anything in the NEC related to electrical requirements in caves. The code explicitly excludes mining applications, but I can't seem to find where something like Mammoth Cave, Ruby Falls, or other tourist-type caves come into play. Any help pointers in...

...When the new bass player walks in carrying only his bass and this: with all of his (good sounding) settings sharpied in place on orange gaff tape.

I dont normally complain about gear, but here at 11:00am in the midst of Easter service, I am extremely perturbed. I have one channel of line6 wireless for our pastor. I like the sound well enough, it's built well, the headset is decent. There's just one overarching problem: THE WIRELESS...

Greetings, I'm getting familiar with Luminair, and the manual is rather lacking. How does one get it to do crossfades, or to have a collection of fixtures fade at different rates, but tied together as they are one fired cue. I assume it is somehow activated from Merge Cues, but the manual (pp...

Greetings. I've got a small 4 channel dimmer pack from NSI (NSI DDS 6000). It has 2 15amp edison circuits and could be used as a wall pack, etc. All four fuses are good, and the DMX indicator lights on four channels also function when sent DMX 512. One half of the dimmer pack (2 channels)...

Everyone, A well meaning party at my church purchased some 575 bulbs for our leko fixtures. Unfortunately, our lekos are Altman Shakespeares, and have G9.5 series lamp bases. I'm looking to sell or trade these bulbs for their GLx equivalents (i.e. new 575w 115V GLC or GLA bulbs). If you're a...

I need to install a vertical raceway to lace up some socapex runs to for temporary lighting of a stage play. I have three questions: Does anyone know the code for separation of this raceway from the AC subpanel conduit that is feeding the dimmer packs? Is there a specific type of raceway that...

Hey all, If you happened to read this title and immediately know what I am talking about, please chime in. I am hoping the community's diverse reader base can recommend me a couple of reputable manufacturers in this space. Surgex is the go to for us in AV, but this is for "heavier lifting"...

One that needs no introduction. As a kid I remember watching "The Secret Life of Machines" which was my first introduction to his music. That show's theme song was a cover of "Take Five."

I'm selling my Crown PH-1A battery phantom power supply, and two custom DIs. I've used the crown for many years to power measurement microphones, but changed my measurement setup and no longer have any need for it. Its built like a tank and requires two 9V batteries. A quick look at eBay shows...

Hey all, So, I've got a pro-grade wireless access point, and what I really need is another router. Rather than go the whole eBay route, I'd see if perhaps someone would be interested in trading hardware. That access point is a Cisco Aironet 1130ag WiFi unit. I would like to trade for a...

Title says it all. Anyone had luck making this work?
