We’re after the quietest 5kVA there is… Can you help?
The question was posed to Midas by a Manchester-based production company, Ear to the Ground, specifically to power part of the Samsung promotional display touring the UK with the Olympic Torch Relay.
The brief was simple… a 5kVA unit with sound levels of no more than 60 dB at 1m, easily movable by two people, and with that, Midas set to work.
The machine side of the operation was relatively simple, and we finally decided on a Pramac P4500 as the power plant. Now for the tricky bit: reducing the noise levels from 96 LWA down to the required level.
Obviously we can’t be expected to reveal all our secrets but suffice to say a series of attenuation panels with a 400w fan to help drive the air flow achieved, when measured a reading of 59db at 1m.
With a tight build schedule achieved in a matter of hours, it was off to Star Events HQ in Bedford, where the whole ensemble was loaded onto a truck and disappeared for its grand tour.
Since finishing the tour at the end of July, the machine and attenuated box have been in great demand, within a matter of days heading up to north Norfolk for the month of August, powering part of the Norfolk and Norwich Festival’s most challenging project yet.
