IA76 Posted April 13, 2009 Share Posted April 13, 2009 Hi We need to purchase a 'portable' PA system which we can take around various venues for spoken audio seminars regarding drugs etc. The most common setup is usually 1 room with about 100 people in and 1 room with about 50 people in. The speaker will be in the room with 100 people in but the sound also needs to go to the room next door with 50 people in. Any recommendations on what we should buy? Ideally we are looking at the cheaper end of the market as this will be paid for via donations and it should be easy to setup & pack away. The system should be capable of being used for a slightly larger audience as well eg. up to 150 in one room & 100 people in the other room. Thanks.

mi-ul Posted April 13, 2009 Share Posted April 13, 2009 Have a look at Yamaha StagePas 300/500 and Yamaha MSR 100 (or I think) 400. What other requirements do you have other than number of people. e.g. inputs (mics / CD / laptop)what mics - radio mics (line level?) do you need phantom power? The MSRs are all powered but have line out to link them, the StagePas are master/slave. Mi-ul Link to comment Share on other sites More sharing options...
Killyp Posted April 13, 2009 Share Posted April 13, 2009 Bear in mind you get what you pay for. If you want something which can produce decent levels of vocals, you'll want the Yamahas. They're the loudest 'PA-in-a-box' systems I've used. I'll be using one this friday for a full-on gig... Link to comment Share on other sites More sharing options...
Jivemaster Posted April 13, 2009 Share Posted April 13, 2009 Chat to Terralec! They certainly used to do a radio mic into a powered speaker/receivew for aerobics etc. See if they can supply two units on the same frequency in the VHF deregulated band. That way the speaker can address one crowd through on LS and the other through the wall via the other LS. Several powered speakers from Gemini to Mackie and on up the range can receive a cabled mic input AND send a link line to another unit of similar sort. You will need a long lead to go round via the doors and windows into the next room. Many of these units are for cheap DJing and can be heavy on the bass (Well bass frrom a little driver!) so careful cutting of bass levels will help voice clarity when speaking.

IA76 Posted April 14, 2009 Author Share Posted April 14, 2009 Thanks for the ideas. I'll have a read through all the link. What kind of wattage is needed for an audience of 150 people? Link to comment Share on other sites More sharing options...
Killyp Posted April 14, 2009 Share Posted April 14, 2009 Depends greatly on the source material and actual speakers in question, but for plain straight ahead speech, ~150 per channel would be enough. Less than that would suffice but your safest bet is to over-do things a little rather than go for something which'll fail the moment someone raises their voice above normal (for example) or someone pops into the microphone.
