UPQ-2P and CQ-2 are potential alternatives, though they lack the same reach and are heavier, making them unsuitable for stick mounting.

Use cases and applications

0 0

UPQs, using the same amp and drivers as JM-1P, are noted for their versatility and suitability for events like small rock festivals and beer gardens due to their smaller size and stick mounting capability.

MSL-4 excels in long-distance speech intelligibility, ideal for political rallies; not suitable for events without additional subs for music applications.

A combination of 6 MSL-4s with 700HP subs and Galileo processing is effective for extended outdoor events, notably for maintaining consistent SPL across large areas.

Setup and maintenance

0 0

Ensure MSL-4s are not tight-packed to prevent high-frequency issues; a gap is necessary due to their 40º dispersion.

Scaffolding with tarps is commonly used for long-term outdoor setups; however, proper waterproofing is crucial to protect amp modules from elements.

Tending to all of this activity is front-of-house engineer Blake Suib, who is taking the FOH reins, having spent countless hours behind a monitor board for Spears, as well as for such artists as Seal, Destiny's Child, Janet Jackson, Annie Lennox and many more. One would think that making the transition from the side of the stage to FOH would be a bit difficult, but Suib has seamlessly made the change, pointing out that the tour's Meyer Sound P.A. has been instrumental in switching positions. As the tour is in the round, Suib and company employ 64 MILOs, split up into four hangs (16 per hang) and 32 MICAs split up into two hangs (16 per hang). In addition, there are 12 M'elodies in the center rig (four hangs) and HP-700 subs with some M'elodies on top “to kind of fill in the floor,” Suib says. Rounding out the substantial and clear-sounding system are hanging MSL4s and C1s for Spears' stage monitors.
