HOSAPXF-105 XLR3F to 1/4" TS Unbalanced Interconnect Cable, 5 Feet

hi: i have a dj mixer with xlr output and i want to conecter to my bbe 382i maximizer with 1/4 unbalanced...will work,??

Will these work with Ddrum drum triggers ?

I have a karaokevision machine and bought these unbalanced XLR3to 1/4 in ts... they don't work...should i have ordered balanced ?

On the xlr side, if pin 1=gnd, 2=hot, 3=cold, how are they connected to the ts side? Is t=hot, s= cold? Or is s=gnd and cold?
