9. Sample configurations and typical use cases
You have probably noticed that a 100V PA system gives you the opportunity to set up relatively complex circuitry. Let's take the example of a centre (an amp), the lines (zones) and 18 speakers in total, all of which can be controlled by additional volume controls. The middle zone in this example is a larger function room, and powerful speakers are to be installed in its ceiling.
This is what the corresponding overview circuit diagram would look like:
Of course, announcements are rarely, if ever, necessary in a restaurant, which would leave a significant component of the 100V PA system unutilised.
Another example shows a system in a restaurant which allows announcements to be broadcast to several areas separately. This can come in very useful, for example if you wish to summon a particular person without this becoming general knowledge.

Check list for your planning
If you have decided that the time has come to invest in a 100V PA system for your company or public facility, you should know the snasers to these questions before you start looking at and comparing products:
| a) | How many sources do I have at my disposal or do I plan to connect (CD player, DVD player, tape, etc.)? |
| b) | How many mics do I need? Is one communications station perhaps sufficient? |
| c) | How many individually controllable areas/zones do I want, and do I need to control these centrally or from the zones themselves? |
| d) | Do I maybe want to run more than one programme, and, if so, how many? |
| e) | Is the system maybe safety and/or security-related according to EN 60849 (Sound systems for emergency purposes) or national norms? If yo, or if you are not sure, please turn to the relevant authorities for information. |
