Separate audio for outdoors using indoor receiver

[Zeppelin21]

Getting a pool. Would like to use my indoor receiver for indoor and then separately for outdoor so either when music is playing inside it's not playing outside or when its playing outside it's not playing inside. How can this be achieved?

Simplest way would be a speaker selector switch like this -- https/www.crutchfield.com/p_543AB22/Russound-AB-2-2.html

If your receiver has speaker A and B terminals you don't need an external switch.
If you may want both indoor and pool speakers to play at the same time then get an impedance matching speaker selector that will give you that option. The switch linked to above doesn't give you that option since it's primarily used to connect one pair of speakers to two different amps rather than the reverse.
