Rolls MX153 1U 1/2 rack mixer. 2 mic/3 stereo source

The MX153 is a one-half rack space, two microphone and three stereo source mixer.

The unit provides a compact and efficient way to mix sources such as AM/FM tuners, CD players, and video players with dynamic or condenser microphones. Applications include background music and paging for small clubs, churches, schools, restaurants, etc.

Each microphone channel has a Level and Tone control. Sources One and Two have Level adjustments and pass through combined Bass and Treble controls. Source Three has a Level adjustment only.

The Microphone inputs are balanced XLR jacks, all Source inputs are stereo RCA. The main output is stereo RCA. An included 12VAC adapter (Rolls PS12) provides power to the unit.

A series of six DIP switches provide important features to the MX152. Two switches apply the 12VDC of phantom power to the individual Microphone Inputs. A second switch sums the program material of Source Three to mono, and a third sums the overall output to mono. Another switch provides priority ducking to Source Three input allowing that channel to mute the other source inputs for use with a jukebox. The final switch configures Microphone Input One as a paging input, ducking the other microphone and Sources One and Two.
