The Media Operator BT from American DJ is an easy-to-operate, all-in-one pre-amplifier/mixer with a built-in MP3 player and a Bluetooth receiver. It can be integrated as a component for an existing system or used as a stand-alone mixer in hotels, bars, restaurants, and other venues.

The unit offers digital playback of MP3 files from SD cards and USB flash drives, with full transport control, while the Bluetooth receiver lets you stream music from Bluetooth-compatible media players. You can also connect five stereo audio sources via the RCA connectors on the back panel and the 1/8" aux jack on the front panel, and an XLR-1/4" jack combo lets you plug in a microphone so you can be heard over the music. Independent volume and EQ controls are available for both the mic and the music channels.

Run the Media Operator BT straight up to powered speakers via the balanced XLR outputs or the unbalanced 1/4" jacks, or use the RCA outs to connect the unit to a system.
