Sound System for Sean Lock

If you're looking to hire a sound system for a corporate event or a band, have a look at my website here.

A few days ago I did the sound for the comedian Sean Lock at a corporate awards function, which took place at the Park Plaza Riverbank Hotel in London.  A Sennheiser EW300 series microphone was set up, but most of the talking was done from the lectern, equipped with a pair of Audio Technica ES915 mics. Front of house speaker system consisted of 6 HK Audio IL12.1 speakers flown in three way clusters.  An additional 2 boxes where flown over the dance floor.  6 HK Audio Elias subs were positioned under the stage, in order to preserve sight lines.  Front of house mixing was accomplished with a Soundcraft GB4 desk, with Mackie digital outboard.

The positioning of the subs made for a very clean looking stage area, also with no speaker stands in sight as all the mid / high tops where flown from a 12m truss, parallel with the front of the stage.  There was a certain amount of power alley noticeable during the DJ set, but this was a price worth paying to hide all the subs.

In order to provide maximum gain before feedback, only one of the Audio Technica ES915's was used, the other serving as a hot spare.

Sean Lock proved to be a very entertaining host, although the official photographer might disagree, being the butt of several jokes!

World's largest photo album- PA System

Last week we supplied a PA System for the Worlds largest photo album.  The record was atempted by Photobox at the Old Truman Brewery in London's Brick Lane.

Sound coverage was needed for background music, and various anouncments for up to 300 people.  We supplied and installed a pair of Yamaha MSR400 powered speakers, together with a Soundraft E6 mixer and a Sennheiser EW100 series hand held radio microphone.
The photo's on display were superb, and many of them were taken by amature photographers around the UK. The subject was World travel.

Subs up for more bass

Getting a good kick drum sound on a gig many engineers would agree, is a factor of how good your subs are.  A pair of 15in drivers is not really going to cut it unless it's a really small gig.  Horn loaded 15s or band pass 15s maybe!  A key fact to consider is this:- to double the perceived volume you'll need to need to more than double the power.  In fact, you'll need around 10 times the power to double the volume (a 10dB increase).  So that's like going from your 1KW system to a 10KW system.
But there is another way... doubling the number of subs will generally increase  your bass output by 6dB.  So let's say you take your 1KW rig, and instead of 1 15 inch sub each side, you put 4 15inch subs each side.  You will have more than doubled the bass output.  For the same power!  I'm assuming your amp will cope here, by the way... It may be asking a lot to go from an 8ohm load per side to a 2ohm load per side with 4 cabs a side connected.  I've blown amps up using them like this in the past.
But what about the mid range and high end?  Yes, you can gain around 3bB each time you double the number of cabs on the high end.  But you'll need to watch out for comb filtering, and lobing.  For small(ish) events, sometimes just pumping up the bass with more cabs can be enough, if you've got good quality tops.
