Good day all. Apologies if this subject has already been covered in another thread that I just didn't come across.
I'm speccing out a system for backstage monitoring. The theatre I am at has just built a new building attached to the performance space, so we have brand new dressing rooms, costume shop, and huge rehearsal space. I'm trying to piece together a system that can originate at the racks near our sound console and be spread to the dressing rooms and other areas.
As I understand them, it seems like a 70v system would be preferable, as I would anticipate 100' to 150' worth of wire run to get to any individual speaker. Never having built a system, and only having a tiny bit of working experience with an existing system, I'm trying to solicit two things:
1. Gear I need to get
2. Things I need to know about such systems
The ideal world is for the distribution amplifier at the sound system to have at least two inputs, one for program feed and one for paging. Most of the amplifiers I've looked at seem to accommodate this easily. I do not foresee the need for the system to expand beyond this, so a TOA system with multiple potential inputs is probably more than we need.
In an ideal world, we'd be looking at each dressing room and the costume shop having 2 ceiling speakers, connected to a single wall attenuator for volume control. In total, 6 ceiling speakers and 3 wall controls.
As I understand it, the 70v system is preferred particularly to accommodate the longer cable runs, yes? And the speakers I would select would need a 70v transformer? Or would most any ceiling speaker work as long as the load is within the tolerances of the amp?
Any help and advice would be greatly appreciated. Thank you!
