PA & SOUND SYSTEM HIRE - Helpful professional hints for correct operation

SETUP AND TEST YOUR EQUIPMENT WELL BEFORE THE EVENT
PA POSITION 1. Position the PA under cover and away from any water. 2.   Position   to   get   best   coverage   of   your   audience.      Mount   the   PA   on   the   stand supplied   and   get   the   sound   to   throw   over   the   heads   of   the   audience.      Every member   of   the   audience   should   have   line   of   sight   to   the   PA   speaker,   when   they look   at   it.      The   wireless   microphones   should   still   work   up   to   30m+   from   the Receiver. 3.   Get   the   level   and   tone   as   constant   as   possible   throughout   the   audience.   Both overall   level   and   frequency   content   can   affect   intelligibility.   You   don't   want   the sound     uncomfortably     loud     near     the     stage     and     impossible     to     hear     or understand   near   the   back   wall.      Get   someone   to   help   by   standing   at   various positions and signalling on best sound. 4.   Keep   reflected   sound   to   a   minimum   (keep   it   off   the   walls   and   other   surfaces). By   reducing   the   level   of   reflected   sound,   you   increase   the   area   in   which   the original sound is intelligible. 5.   Keep   direct   and   reflected   sound   away   from   microphones.   If   you   don't,   you make     your     system     more     prone     to     feedback.     Even     below     the     feedback threshold,   reflected   sound   or   delayed   direct   sound   in   the   microphones   will reduce overall coherence.

PA VOLUME ADJUSTMENT 6.   Adjust   each   input   Volume   Control   to   get   the   desired   balance   between   inputs from   Mics,   MP3   music   etc.      Then   you   can   adjust   the   OVERALL   VOLUME   with   the Volume control. AVOIDING MICROPHONE FEEDBACK 7.   In   most   common   feedback   situations   -   a   microphone   feeds   a   signal   into   a sound   system,   which   then   amplifies   and   outputs   the   signal   from   a   speaker, which   is   picked   up   again   by   the   microphone   creating   a   screaming   feedback loop. 8. Avoid excessive volume Be   careful   -   to   turn   down   all   of   the   inputs   on   your   PA   system   before   powering   it on,   and   until   levels   are   fully   set,   stay   close   to   it   to   make   sure   nothing   starts feeding   back.      Know   the   different   knobs   on   your   PA   system,   and   make   sure   the overall   volume   is   down   as   well   as   any   monitors   or   secondary   speakers   that   you might be using.  When you're not using the PA, be sure to mute the mics. 9. Microphone and speaker placement - you   definitely   don't   want   your   microphone   pointing   at   your   speakers   or   you'll create   a   feedback   loop.   Place   the   microphones   to   one   side   of   the   speaker,   if the   speakers   must   be   behind   you,   and   pointed      away   from   any   speaker.   If   you can,   put   the   speaker   in   front   of   where   the   Mics   will   operate,   as   that   way   the chances    of    feeding    back    will    greatly    diminish.    You    also    want    to    keep    the microphone from pointing at any reflective walls if you can.
