Active Control Monitor


The Neumann M 52 Active Control Monitor is the reference monitor used in many small studios and broadcast vans. It is compact, taking up a volume of 1.8 liters, and offers a flat frequency response, making it suitable as either a control monitor in live broadcast or as a mix monitor in a smaller recording studio. This monitor can be powered by a 12 to 20V external supply, such as a car battery in small broadcast vans or video editing stations. As a multimedia monitor, the M 52 is suitable for both permanent and mobile applications. The speaker chassis is magnetically shielded so that placement next to video monitors or magnetic media will pose no problem.

The enclosure, which is constructed entirely of aluminum, offers maximum interior volume for its size, and inner wall bracing adds a stiffness that eliminates resonant colorations. These factors help the 3" (75mm) high-performance neodymium broadband driver deliver good sound with very low distortion and a frequency response that is flat across the entire pass band.

The volume knob is located on the front of the monitor for quick and easy adjustment. If needed, the knob can be removed to prevent unauthorized operation. The XLR floating transformer-balanced input (+6 dBu) offers a Common Mode Rejection ratio of over 50 dB.

The M 52 Control Monitor is so lightweight that it can be mounted on a microphone stand using the cabinet base 3/8" threaded socket. The monitor can be connected to the LH 11 table stand using the adjustable side-mounted screws that allow it to be tilted at any angle for optimal monitoring. The power switch, mains connector, fuse holder, and the 4-pole XLR input for battery operation (12 to 20 volts) are all located on the rear panel.
