TL:DR - worked but was too close to Jim for the soundwave to work as well as a foldback unit.
Plenty loud for the audience.
Pub 2 - same again, he didn't move the speaker though to a new position so we need 1 more test.
Reports were Plenty Loud from Audience, Jim thinks the unit is under powered.
I reckon we need 1 more test with the unit offset as we did at the markets. Jim had it right up his clacker so to speak. 60 cm from an open mic. wow.
