In our foyer we have three Tannoy 4" CVS4 160 watt speakers fed by a single channel of a BiAmp MXA75 75 watt 6 channel mixer/amp. We have 2 problems with this setup. The first is that it's never loud enough. The second is that if we turn the amp up half way (6 out of 12), the amp will inevitably stop working and not work again until powered off and back on. I do not know enough to say if we need more amp or more speakers. I don't know if the amp is shutting off because it's trying to protect the speakers or if it's just failing. Does anyone have any insight they can share?
I'm not a professional by any means, but
there are several variables that need to be considered in this scenario:
1. Are the speakers wired with transformers
2a. If not with transformers are they wired in series or parallel (i.e. resistance/ohm reading)
2b. If with transformers (I can't help you because I am not familiar with voltage systems)
3. How large is the room?
4. Is this for ONLY speech or are you trying to play music through it?
