An NLT720 weighs less than 50 lbs (22.25 kg), but a mere 7 per side provided by EAW’s Estonian distribution partner Heliart proved plenty heavy enough for the Rabarock Festival in the city of Järvakandi in the Baltic republic. The annual event features local Estonian heavy metal acts as well as bands from across Europe.
These videos of Estonian band Metsatöll show a little bit of the madness.
The system included NTL720 mains, SB2001 main subs and MW12 Microwedges, plus JFL210 front fills and JFL210 side fills supplemented with VFS250 side fill subs. All of it was controlled with UX8800 signal processors, and to get maximum performance from the Microwedge monitors, Heliart powered them bi-amplified, using the “White” DSP settings. Heliart chose the White setting to cut through the high on-stage levels common with heavy metal bands.
Microwedge active processing allows three options for processing created with our development partner Dave Rat of Rat Sound:
- White - As Dave says, “EAW lab coat white – pure and unadulterated”
- Grey – Rolled off slightly at the top for a little less edge
- Blue – Dave Rat’s “blue-collar setting” that reverses out the midrange bump in the most common vocal mics for maximum gain before feedback
