Behringer ZMX8210 V2 Ultrazone 8-channel Mic/Line Zone Mixer - 1U

Here's what Behringer say about the X1204USB:

The ZMX8210 lets you take up to 8 input signals and route them to any, or all of 3 destinations. Maybe you want to play stereo music for clients waiting in the lobby of your office complex and page people in the work area. Another example might be the small church that wants to play soft music in the foyer, mic the preacher in the sanctuary, then send the sermon and music to the nursery. These are all perfect applications for the ZMX8210 – multiple sound sources, multiple zones, total flexibility!

You can use any microphone with the ZMX8210 including professional-grade condenser mics, thanks to the onboard phantom power. The 8 Inputs feature high-quality mic preamplifiers for absolutely pristine sound quality. A master 4-band equalizer is provided to ensure voice intelligibility and address any potential feedback. And if you need more than 8 channels, two ZMX8210s can be linked together to provide a total of 16 inputs.

You can also set the ZMX8210 to automatically lower the volume level of the program music in specific zones during announcements. Referred to as “ducking”, this feature allows the voice message to take precedence over the musical program, without turning the music off completely.
