Hi and welcome to audioholics forum, We will need a bit more information before we can proceed..
First, how many sets of speakers are there?
Second, How do you wire them to your receiver?
Usually, you wire Multiple pairs of speakers to a speaker selector that impedance matches those speaker sets so that they don't present an Unduly high ohm (resistance)load to the receiver.
Typically, separate speaker sets are controlled by their own volume controller in the room that they're located.
Some of these volume controllers are impedance matched already, however you still need a speaker selector if you have more than two sets for a standard receiver to control those speakers.
If you have several sets of speakers, it may make sense to use a multichannel amplifier to control each individual zone.
