A portable pa (public address) system is loosely defined as a system that does not need 110 volt AC power to operate. The system always includes one or more microphones and usually they are wireless.
The size or power of a pa system is stated in watts and there are two types of designations. One is normal operating watts and the other is peak wattage. Any amplification system can only attain peak power for short bursts but can’t sustain that level. So the normal operating power is the most important value.
As to how much power do you need for a given audience size the rule of thumb is 10 watts of power for 100 people if they are directly in front of the system squeezed together as in a church pew situation. So for example the Hisonic HS321 is rated for 35 watts and it can handle up to 350 people as long as they were not spread too far apart from side to side. It is always best to get more power than potentially necessary as the volume control can always be lowered.
The angle that the sound is delivered is very narrow from a single system so listeners off to either side would not hear the speaker as well as those in front of the speakers line of broadcast. For situations where there is a wide spread of listeners the solution is to use two systems. One system on each side of the performance area aimed toward each side of the audience. The Hisonic DUAL 120 watt HS683 AC power system is ideal for a larger audience size of up to 1,000+ listeners in an area up to 60 feet wide by 150 feet deep or more.
It is always best to raise the pa speaker system off the floor and place it on an elevated structure such as a desk to allow better sound penetration through the audience. Ideally it should be elevated at the audience’s ear level. The best solution is a tripod mount such as those available with the Hisonic 80 watt AC power HS687 and the Hisonic 120 watt AC power HS683 systems.
