My amp is putting out 2100w at 4 ohms and I'm running that into a double 18 sub containing two speakers running in parallel 8 ohms 1000w peak. I can use the DSP to limit the audio so the amp never runs into the red, but by my maths, that's still a little on the over powered side (if the 1000w...

Tentatively posting this in varsity because both myself and the other tech have tech as our only sources of income. Last night I saw someone advertising for a lighting tech for a show tonight. Recommended my lighting tech friend, but as I'm flat broke and know my way around a desk, also offered...

Have the manual but the information either isn't in there, or I'm failing to process (or just plain impatient, you'd think this would be in the quick start seeing as failure to do so appears to render the unit useless). How do I ground it? I assume I put one end of my ground wire under the...

I had a few near misses so I started keeping a diary, that works pretty well, except sometimes I stop checking it (in times of not much work and therefore no point). And sometimes I say yes to something and then don't put it in the diary. A few days ago I was offered a small job for tonight...

I feel like this is so obvious it should just be common knowledge but I don't have the right words to start researching. What are people using to convert audio to digital for long runs in their installations? I see JayCar has a product, stereo RCA extender baylun or something to that effect, but...

A council I work for is seriously considering upgrading to a digital mixing console, particularly because they would like to be able to make trouble free multitrack recordings of performances. For live mixing, I'd tend towards the Allan and Heath QU16, X32 seems fine but maybe out of their...

I've come around to thinking that a small, portable, 8 channel digital mixer with wireless mixing capabilities might not be such a bad addition to the tool kit, mainly for lousy vocal rigs with side of stage mixing in pubs/beer gardens. Sourced the mixer all good, just wondering what I need to...

All my hire work so far has been word of mouth, and cold canvassing when I hear a place is looking. This has limited me to very slow growth though and my trickling income says I need to get more proactive finding work for my gear. My dilemmas are, I'd still potentially prefer to be hired by an...

What's the dumbest way you've lost gear? I'll go first, client at a pub was packing up the mic in the front bar and dropped it, it rolled into the cellar through a gap between the floor and the wall and was lost in a deep, murky pool of water (he's calling it a well. I don't remember there...

I landed my biggest hire job to date, a dry hire for the next month. Full PA including DSP and graphics and insertable outboard, and send and return of FX and 4 aux sends in a rolling rack, speakers, mics, mixer - the works. In short, something a bit more convoluted than a couple of Eons on...

What's the good, formal, courteous way to do this? I want to inform a venue that my rate is going up, give them a date that new rate comes into effect and ask them if they still want to book me. It's not a negotiation, just a "I will be more expensive as of date x, do you wish to continue using...

Running some cables for a very stingy client, we're trying to facilitate remote input points for an ipod, a computer and people's laptops being used for powerpoint presentations with sound. The client is happy to use the one input line for ipods and laptops, and we have a second line run for...

So the biggest hire company in town advertised for crew, and I applied, and did not even make it to the group interview which was peopled mostly by complete beginners. Ok fair enough maybe they want to train up from scratch for these jobs. Then they advertised again for experienced techs this...

I've been told just give them piano. My cast of wireless bud mic adorned singers want to hear their voices. What's common practice? Don't want to tell them no way if that's something you'd get on a professional production.

I'm about to put in a bid for supplying an event. It's for a launch outdoors. Expecting about 200 people. Rival company has specced 2 Meyer UPA-1Ps. Looking at the specs they seem to just be fancy 550w speakers. I'm wondering if they have other attributes I'm missing that make them best suited...

Called in today to fix a problem with someone else's installation. The problem was the sub intermittently dropping out. At first we through the speak on connectors coming out of the amp were to blame, the more I messed around back there the worse it got, now I was losing the tops for the main...

Using a Zone 4 controller in an installation, notice there's an irritating high pitched buzz in the system, prominent at 9.4, 10 kHz but there are frequencies lower in that. The signal chain is, working back from the amp, amp to mini DSP, mini DSP to zone controller, buzz box to DI, DI to pc. I...

Trying to sneak this post in here under AV hire as that's the capacity in which I own this kind of equipment.. So my question is, what do you check on your CDJs before you stamp them as functional? I own, and I hire out, but I never play with, and beyond putting a CD in and playing with the...

I kinda mostly almost have my head around this (amp should be rated halfway between the rms and peak capacity or something to that effect, and you can supply a more powerful amp, but without system protection, users might blow up the speakers right?) I don't feel confident enough with my...

If i understand correctly, a pub is about to be seized by the landlord and the leasee, who owns all the good AV gear in there and doesn't want to lose any of it, has started to remove his gear and wants to hire some off of me so it doesn't look like he's gutted it (...and any ownership dispute...
