General
Play music in two different rooms at once with the GR3 2-channel zone mixer by Allen & Heath. This practical device can be mounted in a 19-inch rack with the rest of your audio equipment. You can plug in two microphones, one for each room, and connect a CD player or other multimedia device with a phono connector and fine-tune the sound for both zones separately.
Dispersed audio
Using this zone mixer's 2-band EQ, you can adjust the microphone or the player or both, depending on what you want to be heard in either of the rooms. The mixer even comes with two remote controls so you can make adjustments easily. It's also equipped with an alarm and a pager feature.
