[QUOTE="Brad Weber, post: 32723, member: 114"] Re: 70v System vs traditional... If there are four 8 Ohm speakers per locker room and each locker room is on a separate channel then using series-parallel wiring it would be quite easy to wire the system to have an 8 Ohm load per channel (two speakers in parallel in series with the other two speaker also in parallel or two speakers in series in parallel with the other two speakers also in series), you'd have to find out how the existing system is wired to determine if that is what was done. That approach may also explain why a speaker going bad in each locker room led to the demise of the receiver as a speaker going either open or short could significantly change the load on the amp output and cause the receiver to fail. At least in my experience, a 70V system can typically provide more than sufficient level and quality for a locker room, but perhaps it would help to define the goals and expectations before discussing potential solutions. What type of venue is this, is it a fitness club or golf club or college/pro athletics facility? How do they use the system and what are the expectations and goals for it? What is the budget? Do you plan to replace all the speakers or to try to reuse what is there? Do both locker rooms always get the same audio or do they want to be able to address them as separate zones? A simple example of how this may matter is that a consumer receiver might make sense if they are using one with a integrated FM tuner for music or have multiple sources hooked to it, however it may not make as much sense if there is a paging mic or if it is tied into a building wide paging and/or background music distribution system. SO I think it is important to know what you are trying to do before addressing how to best accomplish it. [/QUOTE]
